The Ozzyboards TubeMagic Drilling Jig (1”) is an innovative tool which allows teams to easily make accurate frames and mechanisms without the need for costly pre-drilled tubing. Featuring 7 hardened 5/32” drill bushings on 1/2” intervals, this tool will withstand many seasons of heavy use. The adjustable end-stop allows teams to precisely select the width of their chassis wheel well in 1/4” increments. The ability to remove the end-stop allows the jig to be placed and clamped in the middle of a 2x1 or 1x1 tube to create a precise ½” hole pattern without the need for the entire piece of tubing to be pre-drilled.
This product will be black anodized and come with the drill bushings pre-installed. The high-quality knurled thumbscrews are suitable for most clamping applications but standard socket head bolts will also be included for those who want the extra security.
The Drilling Jig is available for preorder now for $35 and will be shipping in approximately 2-3 weeks. We will update the thread as well as email customers when we have more information on availability.
With the increasingly large community of FRC Teams who use CNC Routers to produce aluminums parts for there robots we have evaluated a range of different single flute endmills and are now proud to offer high-quality endmills in 4 and 6mm sizes.
The 4mm is a workhorse Solid Carbide endmill capable of boring and slotting at high speeds. This size of endmill is ideal for teams who have routers without ATC Spindles and want to be able to cut parts fast without needing to worry about changing tools. This endmill is capable of boring 5/32 and 3/16 holes with ease while still being able to achieve decent speeds and MRR while slotting. Cutting dry this endmill is able to cut through 1/8” aluminium sheet in 2-3 passes at 60IPM+ and with the addition of a mister can comfortably cut through 1/8” aluminum sheet in 2 passes at 80IPM+. A chipload of 0.003-004 is recommended. This endmill is also ideal for routing polycarb, Delrin and other plastics with ¼” DOC and 100IPM+ being possible in these softer materials.
The 6mm is ideal for applications involving slotting and pocketing in thicker sheet/plate, 1/8” aluminum sheet can easily be cut in a single pass at speeds of over 100IPM but be careful to ensure your work holding and machine can support this. These larger endmills are also incredibly durable and difficult to break, these endmills will make huge numbers of parts before they need replacing, just a couple of these endmills are capable of making an entire seasons parts.
Shipping on Endmills is free of charge and is done from Australia (will take around 1.5-2 weeks to arrive)
The Jig is certainly an interesting idea we might consider. We actually had some issues this season with the uniformity of the holes in some of our pre-drilled stock, so this might be a good alternative (not to mention the lower cost of material).
It also looks like it’s something you could probably do on a drill press with limited experience, potentially providing a good training tool for new students, and also freeing up work time on our CNC Mill.
I’d love to buy one, but last fine we bought your other big we got absolutely soaked in brokerage fees. UPS and FedEx c.o.d. charges can exceed the price of the part! I don’t suppose you can look at pre-clearing items shipped to Canada, or distributing through different who does (Andymark, Vex)
Aside of coming with 5/32" drill bushings (my team uses 3/16" anyway), are there any advantages to the OzzyBoards TubeMagic Drilling Jig compared to, say, this HarborFreight jig? Do you have any of them in-hand yet, to speak to Quality Control and tolerances? When a vendor only has CAD renders of a product, I’m always a bit skeptical, but this is doubly true when said product is a jig and thus its whole purpose rests on quality manufacturing and tight tolerances of the production pieces (not just the design).
5/32" was chosen because it works well with the range of existing COTS gussets available. We have made a number of aluminium prototype/preproduction models of this product, but they aren’t anodised and we are waiting on that particular thumbscrew. We could post photos of some of these but it wouldn’t be representative of what the product being sent out would be like. The two main areas which require good tolerances and the overall width and the press-fit of the bushings and we have had no trouble hitting those on an OMIO on our prototypes. Our manufacturing partner is currently making several final anodized prototypes and we will share photos of these once they are available.
The key advantage of this product over said Harbor Freight or other jigs is the adjustable Endstop system. This allows teams to only have to drill holes at the end of there drivetrain tubes as well as being able to accurately select the chassis wheel well size in 0.25" increments. On a chassis there are usually 8-16 identical hole patterns which need to be drilled, this tool allows this to be done very quickly with no adjustment or messing around, just slide clamp and drill. As long as you can cut two tubes to the same length building an accurate chassis with this tool is very simple.
You can see in this video where we use a similar tool (in house) to create a standard hole pattern on our driverails. It’s a massive time saver! Nice product!
Been making some prototype gearbox plates for a potential product out of 1/4" aluminium plate today and thought I would film some cutting.
This is an OMIO X8 router and will happily remove 3 Cubic Inches of aluminium per minute with the 6mm Endmill while getting an amazing mirror finish.
This is full DOC pocketing in 1/4" plate with a 0.1" stepover at 120IPM@20krpm and there is plenty of potential to increase the stepover and IPM. At these speeds it is better to simply clear out all the holes and pockets rather than contouring/slotting .
I don’t want to rain on their parade, but to be clear there is nothing special about the endmills they are selling that’s enabling the performance you’re seeing in that video. This is probably the same one WCP sells (or nearly identical) and is some generic Chinese off brand.
I got to check these out at champs, and they’re a little different from the WCP ones. The WCP ones have a straighter helix and are a lighter color, for some reason. Chances are these are some generic Chinese brand, but as long as they’re more consistent than the HuHao ones that I’ve been plugging for some time, I’d be willing to switch to them.
I have seen HuHao 6mm endmills get similar performance in aluminum. The main advantage of these would be reliability and life. IIRC the HuHao ones get worse surface finish than these do in aluminum, so there’s probably slightly better geometry on these than on the generic ones.
1072 is sponsored by OzzyBoards, but we don’t have a CNC router yet. Once we find lab space for an Omio we’ll try a few of these out.
Yep, this was more meant to be an example of what is possible on a CNC Router commonly used by FRC teams with a tool of this size and type. A lot of teams don’t realise that with a good quality 6mm or 1/4" single flute tool you can achieve high MRR on an OMIO or similiar machine, a lot of teams run very slowly with small tools.
This tool can definitely be pushed more on a rigid machine capable of faster speeds (probably need servos)
I have done a considerable amount of testing with a number of different low-cost 6mm Single Flute Endmills and this particular one is the best I have tested in terms of durability/life, finish and consistency.
In regards to these vs HuHao, wanting the fix the issues with the HuHao bits while still providing good value is one of the reason for selling these bits. They are more expensive but also perform way better. There is a lot of inconsistency with the HuHao bits, especially with the 4mm which often come ground slightly differently so you basically need to change your feeds and speeds when you change tools over. Our 4mm can be run faster in both boring and slotting vs the HuHao 4mm while giving a better finish and life. The life of both tools is also very high, a few 4 and 6mm endmills($40-50 total) will happily make an entire seasons worth of parts.
