Re: New AndyMark Product Game Hint???
You are assuming that the zeroes are not significant figures already. Zeros can be significant.
Tell a machinist to make a part with a dimension of 1.00000" and see how hard they hit you. Whereas...

Re: Rivnut Tool
If your ACE is selling 6061, good for them! But I would bet you $10 that it's 6063 and I HATE that stuff, super gummy and nowhere near as stiff.
Please don't buy hardware store aluminum. Please.

Re: Rivnut Tool
Installation is time consuming and rather annoying. Anything larger than a #10 rivnut takes some considerable muscle and/or the use of a cheater bar(s).

We had good success with Delrin hubs in our shooter wheels this year. Went with around 0.004" over size press, some may have been more like 6 >_>. We have a big arbor press and I may have gotten a...

Re: Team 4499's first Homemade Gear!
You know what really cuts my gears? Those Highlander guys!
Looks nice, I would suggest making gear stock and cutting pieces off of it as it is likely to be more time efficient. Also use 7075 if you...

Re: pic: 4908 Prototype West Coast Drive
Back when we used the cRio, this was more viable. Now that we have the RoboRio you need to exercise much greater care to prevent costly brown-outs. You NEED current sensing in your code for this to...

Re: Would it be a Penalty?
If you are just trying to bump into them to try and get them back upright I feel the ref might be unclear as to your intentions. It is entirely possible that it could appear hostile. Remember that...

Re: Would it be a Penalty?
It would depend on exactly how you were able to do it. Most cases you would get a penalty I believe, there is a good chance of damage if not done just right.

Re: New AM Shrink Tube Solder
There is no way there is profit margin in using that amount of Indium, that stuff is like $0.50 per gram, in bulk. I spent $150 for a half a pound of the stuff, but I will say I do like the taste and...

Re: Do you use 3d printed mounts?
1678 does quite a fair bit of 3D printed parts for mounting electronics. It makes space management much easier. We also make a lot of shaft spacers with 3D printing.

Re: Recommendations for Restoring Router
Well, I'm jealous.
The rust doesn't look so bad really, scotch-brite and some oil should clean it up nicely, maybe a wire brush too. Replace the chain if you feel so inclined.

Re: pic: ???
They could have at least had the decency to properly center the parts in the jaws, but no we'll put it in offset and not worry about it.
Unless..... maybe they did it in the 3 jaw?

Re: pic: ???
Also, why the heck are you facing down your square parts on the lathe in a 4-jaw chuck? How bored are your students and who taught them that was a thing in the first place?
