Building Out a Workshop
 
My team is now a 3rd year team, and we are growing, in team size and in team skill. Around this time every year, I keep starting to think about what more to do to allow the team to gain and grow technical skills.

I want to put together a proposal to our school to build a workshop that would be primarily utilized by FRC and FTC teams at school. The room would ONLY be used to build robots. Basically, no tools outside, and no non-robot work inside.

Some background as to why:
We're still a very young team (with a not highly mechanically skilled mentor, me), and we are still climbing the ropes together when it comes to new tools. We primarily use powered and un-powered hand tools, and a Chopsaw this year. Last year was primarily un-powered hand tools.

Currently, our "workshop" (for chopsaw and storage) is a 6 foot by 15 foot space. It's difficult to build in here and so un-powered hand tools and building is done in the adjacent computer classroom. That also proves a little difficult as we don't have any proper benches and end up using the floor (darn stable bench, downside is the floor loves to make bolts/nuts/wrenches disappear).

It's dawned on me (actually ever since we started) that if the team has any future there needs to be a proper investment. A proper workshop with space to build and eventually expand the depth of tools, I think is opportune for a team at our stage. 3 years is when most teams get lost, and I think it would benefit us to make an investment and stand firm. Quick side note: I don't think we're ready for any advanced machining tools (lathe, mill, CNC) but I do want to keep that in mind for 2 or 3 years down the road.

So my main questions:
  1. What is a good size for a future-proof workshop dedicated to building robots?
  2. Any specific power, structural, extraneous feature recommendation? Think dream-workshop from scratch...okay...dream budget workshop.
  3. Our next tool to be purchased will likely be a drill-press and potentially a bandsaw. Any tips or recommendations here?
  4. I'll also take recommendations for organization. We currently have a "cheap" Craftsman tool center purchased this year, and a bunch of stacking bins to do a bit of re-org.


If you have any more input on how to better or properly train students with regards to tools and machining, post away. We as a team are about reaching the limit of my knowledge, and this is an attempt for me to try to stay a few steps ahead.

How many students do you currently have and what do you expect your growth rate to be over the next few years?

Re: Building Out a Workshop
 
We currently have 10 students. I expect us to continue growing to about 30-40 students over the course of 4 to 5 years.

Re: Building Out a Workshop
 
Regardless of team size or growth, there are a few staple items that would be good to have.

-Central compressed air (Our school has a compressor in the basement that we are plumbed into. If your school has something similar it shouldn't be too difficult to add)

-Multiple circuits of 120V and 220V (240V? I'm not excatly sure on the standard, but look it up for what you might use to power a mill or lathe) power and possibly ceiling mounted cord reels to get power wherever you need in the shop

-Garage door. It sounds silly but without it getting robots in and out is way harder, and you may not be able to move machines into the shop in the future

-Good internet/WiFi and potentially a server to store team files on

-Lots of organizational storage spaces. Think shelving units for parts, hardware, small raw material, and anything else you can think of ever wanting to store. We go up pretty tall on ours, and it works as long as you keep light stuff at the top (foam, rarely used supplies like car wash stuff, pneumatic and surgical tubing, tread, etc). Also, racks for raw metal and wood, including common bar and tube stock, shaft stock, and sheets/plate materials. Additional closet space to store assemblies and to organize parts by subsystem is also incredibly helpful. Basically as much storage as you can get, try and fit it in everywhere. You will always have something new that you decide to keep around and useful stuff just accumulates. Obviously tool organization is very important too, including even seemingly stupid things like a spot to charge drill batteries.

-Potential benchwork around the outside of the shop, and also caster-mounted mobile benchtop spaces for the middle of the floor work well. You can also put storage within your benchwork.

-If possible, tables and chairs to sit around, or chairs for the benches. Nobody wants to stand for hours on end every night and it gets tiring (Also people like to sit when they eat). Also, try to get a carpeted area for the CAD/Programmer people so they don't have to work in a crowded, loud, dusty shop where their electronics can get damaged. This carpeted area can double as a place to test drive your robot if you don't have space for a practice field, as long as the carpet is similar to FRC carpet.

-A fridge and possibly a microwave or more if you can get away with it, even if just to keep cold drinks around

-Never underestimate the power of speakers, having some music in the background (at a safe level) is nice because it discourages students from using headphones, and most people like having something to listen to while they work (I stress again, do not play music at a level where clear shop communication is impossible or any unsafe condition is created)

-If your team does a lot of bearing work or broaching, consider getting an arbor press. It's a really useful tool for a lot of different applications, and something that will be noticeably missed if you get one and then take it away

-I prefer free-standing drill presses and bandsaws to benchtop ones, they are generally bigger, more robust, and more comfortable to use. I also find that they are generally of a higher quality as well, and can do more heavy-duty work. That being said, if benchtop is all that is in your budget or size restrictions, then by all means, the difference isn't that big of a deal

-Make sure your workspace is bright. All of our mills and lathes have clamp-on spotlights (super cheap, and wonderfully helpful) attached and extra fluorescent tubes overhead, as do some of our other tools. I am of the firm belief that a bright work area is a safe, accurate work area, and it just makes everything easier.

-A sink and running water is absolutely invaluable to a shop, as is a first-aid kit and safety goggles cabinet. Also, some small lockers for students to keep their stuff is always nice to have (I always kept my personal safety goggles, calipers, and a couple other oddball tools locked up so as not to lose them, and it is nice to not have to take them home all the time)

-Additional tools to consider if you are thinking about doing more precise work include a few good calipers (I prefer dial over digital, but to each his own), micrometers, possibly a scale to weigh the robot, and more accurate punch sets


With regard to machine safety, obviously nothing is as valuable as common sense, but there are some things that every student needs to know about before entering the shop. Here is a pretty comprehensive safety list from the wonderful Team 358. Also, before buying a new tool of piece of equipment, read up on its particular safety precautions and procedures, as every tool has its quirks. For technical information and other general robot stuff, 358 has some amazing stuff on that as well, as do some other top teams, like 1114.

This seems very comprehensive, but in submitting such a big proposal to the school, you should plan everything out meticulously, once you have a hint that it might be possible to move forward, in order to prove that you are truly dedicated to the task and prepared to see it through in a constructive, futureproof, and responsible way. Generally, showing that you did your research will make administrations more willing to help you out, since they can bank on your plan actually working. Obviously not everything here will be ideal for your team, and there may be other things that you deem necessary to your shop, but this is a general outline for what I would do for a dream shop on a limited budget. Best of luck, this would be an excellent step forward for a growing team.

Re: Building Out a Workshop
 
There are a ton of great tool and machinery recommendations in this thread:
http://www.chiefdelphi.com/forums/sh...d.php?t=115165

For storage of large items like wheels, sprockets, motors, etc, the FRC Kit of parts/2015 game piece totes work great.

For storage of small parts like screws, nuts, pneumatic fittings, etc compartmentalized storage trays are a good choice. Since you're asking about a dream shop, then I would recommend the "Design-Your-Own Steel Small-Parts Drawer Cabinet" from McMaster, as they are very heavy duty and having the drawer slides for each tray is very convienent:
http://www.mcmaster.com/#bin-boxes/=wqqq38

Have a large open building space with power and compressed air drops that hang from the ceiling on retractable coils; this way there is always a close source of power without the tripping hazard of cords/hoses running on the floor. Have plenty of really heavy duty workbenches and tables - ideally at a light color to make it easier to find a dropped screw. Light-colored epoxy floors are great - again, the light/white color is great at helping to find the inevitable dropped item.

Have plenty of whiteboards around. Have a few computer workstations with large monitors near the building area for CAD/part reference while building. Have good shop vacs and cleaning equipment - a clean shop is a safe shop. Fridge, freezer, microwave and coffee makers are not to be underestimated. Good speakers are a valuable asset. Have a few comfortable chairs/couch/hammock to relax for a few minutes during long meetings.

Re: Building Out a Workshop
 
Funny... you two guys just described 1197's shop. At least to a point. I didn't realize it was quite so ideal.

We've got a large open area with workbenches around the outside, a small loft (used for leadership/mentor small meetings), a room for electronics (why that has one of the compressed-air drops is beyond me), and a storage/meal room.

And yes, we've got speakers and some random degree of organization (read: 90% chance of finding what we're looking for and the rest is finding something that will work) and the fridge/microwave/coffeepot. Some lockers. Plenty of power drops in the ceiling, and yep, they're retractable. Not a lot of practice space, but getting out through the garage door isn't hard and there's a parking area out there that we're able to largely keep empty.

That big room used to be the auto shop at the school. The lifts and such are long gone... but the robotics team has been busy.

In many ways cars are (or are about to become) most people's most intimate contact with robotics. The suitability of the auto shop is not just functional, but symbolic. :-)

I'd suggest considering what the shop will be used for "the other 46 weeks" of the year. Summer workshops? Classes? Headquarters for pursuit of a Chairman's award?

In our case...driver practice, prototyping, and other FRC offseason activities. It's not open as often, though.

Re: Building Out a Workshop
 
We have yet to find the ideal workshop. This year is pretty good, though. The Pre Engineering classroom is now in the old Print Shop (progress?), and there are several nice work benches with drop down power cords above, a roll up door, and a little bit of storage space. Unfortunately it's a classroom every day, so we have to put our stuff away when we're done with it. But the lighting is good, the teacher plays music often, there's a table to serve dinner, plenty of computers with CAD software, etc. There is a carpeted hallway where we can play with robots, and just a short hike to a larger play area. We even used the shop air once.

Somehow our team has managed to stay about the same size for ten years, with about ten "core" students, and another dozen or so that hopefully are getting something out of it. Since we don't seem to be able to get more mentors involved, I guess the size of the shop is just fine.

cadandcookies 14-04-2015 01:55

Re: Building Out a Workshop
 
I'd also suggest a bin cabinet for storage. When I was on 2220, we had a couple that we mounted on caster wheels that stored everything from safety gear to seven seasons of partially disassembled gearboxes. They're a bit pricy, but they're fantastic things, both for teams that have a dedicated build space and those who have to be more nomadic-- especially the latter, though.

I'm also a fan of good workbenches-- whether it's a station work table like this or a more table-y table like this (as a side note, I'm not recommending this specific supplier-- these are just examples of what I'm talking about-- research is key!).

As for size, I'd lay out precisely what you want in it-- even if you can't afford it all now. If you want to have a Bridgeport and a tooling cabinet in there, but can't afford it now, lay that out. If you're talking 10-15 people in the shop now and maybe 30-40 later, I'd plan for 2-4 workbenches plus whatever machinery you deem necessary.

I'd definitely second/third the idea of having a "clean" side of the shop-- keeping everyone in close proximity is huge, so if you can swing it, go for it.

Best of luck with your pursuit of a new shop space, and keep us updated! It's always cool to see what teams are capable of getting accomplished!

Re: Building Out a Workshop
 
Speccing out, purchasing, and creating operating plans for model shops and makerspaces at universities and corporations is my job. I would like to share with you some pitfalls that are too easy to fall into.

1) Maintenance and operating costs money. Remember that you are going to need replacement parts, consumables like cutting tools, oil and grease. All of these cost money. Make sure you budget for these. If you are purchasing through a school, build operating costs for a minimum of 5 years into your budget. Always be thinking about sustainability.

2) Plan for training. Just because someone there right now knows how to use these tools does not mean they will be there in the future. Make sure you have a plan for training at least a few people. For manual machine tools this may just be watching some youtube videos. For CNC machines and other more complicated machines, you may need to pay to have someone trained by the manufacturer or put together resources for learning how to operate it.

3) Remember you need tooling. budget 20-50% of the purchase price of a machine tool for work holding and tooling. In similar vein; Make sure you have the software you need. For example; a CNC mill is not a whole lot of use without CAD *And* CAM software. It can be a killer if your school gives you a grant for that $50,000 vertical machining center but not for the CAM software to drive it.

4) work space is just as important as the tools to go in it. Make sure you budget for work benches, storage, power distribution etc.

5) focus on the basics, then move to the more complex stuff. Make sure you have a good set of hand tools before you start moving to machine tools. With machine tools stick with the most universal stuff first then move to the fancy computer controlled stuff.

Re: Building Out a Workshop
 
Additionally, you can save a ton of money by building shelving and workbenches/tables from scratch. Use good dimensional lumber for the support, and thick, smooth plywood for the benchtops. We like it because it's cheap and easy to replace, meaning you can mount stuff to it and when the tabletop gets really unusable its not too difficult to change to a fresh top. For example, we usually build plywood "walls" around the bench that holds our bagged robot after bag day, so that students in the shop (it's also a classroom space) don't mess with the bag.

If you go down this route and end up with the machine without the software, the student licenses of SolidWorks work just fine with HSMWorks Lite.

Some of the features are disabled in the Lite version but you can do a lot of the basic stuff with it.

Another CNC issue is make sure you understand all the parts of your CNC system before you buy it. A CNC plasma table without the plasma cutter is not very useful. A manual mill with retrofit and no control is equally an issue.

Re: Building Out a Workshop
 
Sorry - meant to post on another thread.
Any ideas on how to learn to use these tools should we buy them? Whether a lathe, a CNC, milling machine, or whatever, we don't have any mentors with experience using these tools.
Example: Off the top of my head, I can't figure out what I would do with a lathe that I couldn't do with a drill press and a bit of patience. Based on the posts, there's obviously something else they're good for.
Are there any on-line tutorials that cover use of these tools, or will each turn into a high-priced coat rack unless we find a local person who can teach us to operate it?

It's already free. You just have to do some legwork to get in touch with a rep and get licenses.

We've been doing that for the past few years. It usually takes a while (2-6 months) and the licence they give us only allows for one installation. Autodesk education makes it a one click download.

I think people overestimate the necessity of 3D CAM for frc, we've never found the need to do anything that HSMexpress couldn't handle.

As far as machining, these are some of my favorite Youtube channels that I've learned a lot from:
-Abom79
-Tom Lipton
-Tubalcain
-Keith Fenner
-Keith Rucker
-Arduinoversusevil (not machining centric but hilarious)

Also, here are some decent resources from MIT: Overview and videos

We spent quite a bit of time before the season started getting HSMWorks license for all of our computers through autodesk education. Eventually, somebody emailed us a code that we could use many times, but it won't work unless the same user logs in on the same computer to use HSMWorks.

The HSMExpress still comes with adaptive clearing/pocketing feature and the same set of post processors, so there's almost no reason to go after HSMWorks.

I second Jared entirely. South Bend's How to Run a Lathe is definitively the best single source for instruction on lathes. The link below links to some free online PDF versions, and there are newer copies available online. The book literally explains everything about lathes.

Re: Building Out a Workshop
 
Thank you for all the great tips. Here's a few follow up questions and things that I've been thinking about. If you feel very strongly about your recommendation and I have not included it let me know, so we can talk.

Follow up questions:
- My big question is does anyone have any recommendations as far as size? Clearly bigger is better, but I'm thinking about something around 450 to 500 sqft to be reasonable (I think I was looking at 30 x 18)
- Also what's the use of the compressed air line? When I was on the high school team, we had one in the robotics room but I didn't see that we got much use of it.
- It's likely that we will be unable to get a garage door, as they re-did the end of the school (and actually removed a loading dock garage door). Do you think it's still possible to load in a floor-standing lathe (maybe...mill) through standard double doors?
- Power. Bringing in a 220 (or 240V) line, is it worth it? What would it be most used for? Estimated cost?
- I tried looking in the other threads but most everyone talks about mill/lathe/cnc recommendations. Anyone have recommendations for a good floor-standing drill press?


Things that will definitely be getting purchased/in the shop (if we get one):
- Re-vamp our hand-tool collection: Allen Key sets, Screwdriver sets, Socket Wrench set (anything else that is key for hand tools?)
- Floor-standing drill press
- Mobile benchtops for assembly
- Workbench lining the wall (with vises)
- Storage: small part shelving, tool shelving, handheld tool peg board, raw material stock rack
- Power: Definitely, ceiling (or wall) retractable extension cords
- Misc: Stools for mobile benchtops, 1 to 5 computers for work, cabinet for storage of paper/books/dry food, sink

An air line in the shop allows use of compressed air tools. The benefits of these are high power density and no need to recharge, while remaining relatively portable. An air riveter can be very handy for putting together any significant number of riveted joints, and is invaluable if you start doing lots of sheet metal construction.

WRT getting machines in - if you can mange to get a loading dock/garage door installed, it's ideal. However, in the event that you can't, there's not a lot of machines that you can't get through a set of double doors (provided they have no center post, or it can be removed). You can almost always find a way to get the machine through the door, be it removing the head assembly on a bridgeport and rolling it in on a high-cap dolly, or using an engine hoist to lift up a lathe to roll it in. It helps a lot if you have someone experienced with rigging or moving machinery to direct the process along.

You'll need a higher power drop for either of those machines, if they're of any reasonable size. I can almost guarantee your school has 240 volt power already, so it's a matter of getting a drop installed. Cost-wise, talk to whoever manages the contracting at the school.

For a drill press, you can get a decent Jet drill press in the ~$500-600 range. It's not a precision machine, and you have to treat it kindly, but it'll drill holes, and it'll be a rather robust machine for students to utilize. If you can find an old used one from a local machine shop, that's also a good choice, but be prepared to give it a little TLC to make it happy.

Good luck getting your shop together!

Ah ok. I think we're some time away from sheet metal. I was looking up videos of installing an internal compressed air system and it doesn't seem terrible.

Cool this is good news. It's just likely that the room will be put next to the computer lab which is in the middle of the school.

I linked the Jet because it was the first thing to come to mind as a decent, robust floor-standing drill press, and is generally available semi-locally to a lot of US teams. JETs are also sold, often more cheaply, as Grizzly or KBC (I think there's a couple other rebrands, too) - be sure to look for that kind of tool at a cheaper price.

As far as a band saw goes, a good floor-standing 13 3/4" Delta (or equivalent Jet/Grizzly) can sometimes be had for $250-300 from Lowes or equivalent. Surprisingly, I hear the Harbor Freight 9" benchtop bandsaw or MSC/Northern equivalrnt is pretty good. It is harbor freight, though, so keep that in mind.

You might also consider a horizontal band saw, instead of (or in addition to) a vertical one. Horizontals are nicer for cutting thick materials and pieces with larger structural cross sections, and can cut longer sections off without having to waste material with angle cuts. Basically, anything you'd do with a hack saw is work best suited for a Horizontal. They're not suited for more delicate work, though - you can do a lot on a vertical bandsaw with a steady hand. Many horizontals can be changed to be vertical position, and come with a table for this use. Brand recommendations are the same.

Used band saws can be a good idea in some cases, if you can find a robust older machine. You can often get a hold of well-used but still-good band saws for a decent price - local auctions and repocast are the places to look. Keep in mind you might be getting into a little restoration work if you go that route, but it can be well worth it. I was spoiled... we got to use a wide-mouth bandsaw that looked something like this. The thing cuts like a dream, and has a mouth wide enough to accomodate any work you throw at it. Finding a machine like that (hopefully not that big) is a great pickup.

For all bandsaws, remember to get wood or soft material blades (large tooth) instead of metal blades for cutting aluminum - see here for why.

You might also consider a horizontal band saw...

We've actually got a chop saw, so I'm not sure we'd go this route for now. I think a vertical band saw would allow us to make cuts beyond straight cuts, hence the interest.

Please, correct me if I'm wrong or if you disagree.

Probably will want to for the vertical, then. You can do some nice angle and curve work in tube/small sheet on a vertical.

You do not want a wood blade for cutting aluminum...you just want the right tooth count/type. For aluminum a variable set/variable pitch blade is what you want. We use this one, from McMaster

You're right, I used the wrong term for a coarse-tooth blade. I usually hear those called wood blades.

For what it's worth, McMaster does claim that their "Blades for Softwood" are appropriate for aluminum:

Appreciate the correction.

I believe the rule of thumb is that you should always have 2-10 teeth in contact with the metal.

Ahh! That's what I'm missing here. The blades for softwood have a super coarse pitch (4TPI/0.25"). That would make the variable pitch blade Cory posted with the 10-14TPI a way better choice for the thinner stuff we tend to cut in FRC.

Today I learned a bit more about band saw blades.

For power tools, please consider that you have to live with the darn things for years, so don't skimp on quality. Don't buy Harbor Freight. It will drive you batty. Check that the drill press doesn't make the drill bit wobble, and that the table is square, and other such things. Get a band saw that's made for cutting metal, as they are stronger and last longer. Delta is reasonable quality.

Generally speaking, old power tools are better built than new Chinese ones, if you can find them. But make sure you have someone on call who understands how to make them work well and keep them tuned up.

We have what is basically this same saw. Ours is from Northern Tool, and it may have some slight differences, but again - essentially the same. This has been one of the best additions to our shop. It has been running flawlessly now for three seasons. It can be used either vertically or horizontally (requires addition/removal of the table) but we very rarely ever use it horizontally. (We have a power miterbox with an appropriate blade for aluminum and a large chopsaw set up for ferrous metals that are better choices for straight cuts.)

The saw is usually about $250 from HF...but watch for their coupons. They occasionally offer a 20% off one item coupon. I'm seriously considering a second one of these for my basement the next time there's a 20% off coupon.

On bandsaws, we recently had a need to buy a couple saws in a hurry. We chose the Grizzly G9743 7x12 horizontal and the G0555X vertical. They haven't arrived yet but I'll post back when they do.

We went with Grizzly because they have good parts availability and they're a fairly reputable supplier, albeit not the top quality in machines.

We currently have a G9742, and it's been okay. The motor caught fire about 2 years into its life, and the power switch gave out about 3 years in, and the hydraulic down feed is now going out at about the 4 year mark, but overall, it's been an acceptable tool for its cost. We cut big bar stock on it all the time, and pretty darn straight once we got it dialed in. Slow, but it gets the job done.

The new saw will support a bigger blade which will be nice.
