JCDammeyer's 42 projects

I agree, In part. No air in or around the grinders to blow swarf around, but once removed, feel free to blow a vise out. If you have coolant, a wash down hose is sometimes better. Not always. Air in a shop is another hot button topic. So polarizing......Around other machines it's ok to blow chips out by me, just be careful to not blow stuff INTO crevices, and behind way covers etc. Used sparingly, and correctly it's great. Used wrong, it's destructive. I don't like blanket rules trying to cover all situations. Education and proper instruction are much better than catch all rules like "no air at all". Engage brain first before doing anything. YMMV.

Sorry John, didn't mean to start opinion wars in your thread lol.

Using air in the shop is similar to using a pressure washer on a machine. I would cringe when fellow dirt bikers would go at the mud on their bikes - full blast on the suspension components. In those areas, I only used garden hose pressure and was careful even with it. As Dan said - when used correctly/carefully such things can be a big time saver and not be damaging. I regularly used the pressure washer on the muddy bike but only for specific areas and very carefully.

Gerardi vises are great workholding tools. I think they actually hold stock better, and square-er than kurt style, but the moving fixed jaw was a non starter for me.

Didn't they show you how to lock the fixed jaw down? I do it all the time when needed for reference dimensions etc. The beauty of it is that leaving the moving jaw unfixed still retains the pull down feature. But if you want, you can lock them both down.

Yep, I know how to lock the fixed jaw down. But I couldn't figure out how to swap to aluminum soft jaws quickly, or to talon grips, or back to hard jaws again....

Gerardi's were great, but they weren't always the best or most versatile work holding tool available. Another downside is they had way more nooks and crannies for chips to pack into. A bit of a PIA in a VMC, when blowing out between parts. For us, they were way more useful as a secondary vise, than a primary one. Everybody's needs are different. They had their place, it just wasn't on my mill table.

Tweaked the depth of the pockets that are there so the heat sink doesn't run into capacitors on the PC board.

All done.

Nice work John.

Thanks but the credit all goes to @kstrauss for making them in the first place. Had I evaluated his sample properly or even just sent him a sample I wouldn't have had fun in the shop.

All my projects tend to be one-of type machining. Doing a bunch of something is such a learning experience. It's also really clear that I don't quite have the backlash setting correct and that I really need to get ball screws for this puppy.

I even used the timer on my phone to calculate 02:24.59 for one complete cycle. That includes manually moving the lever for cooling air. The G-Code does turn on a relay but there's no wire from the relay to the solenoid. #42 on the list...
