Flipping the grinder onto it's side is the easy button for 90 degree angles, and particularly on an inside radius. Being able to lay your blade flat on a work rest and bump it up against a contact wheel running left/right makes it much easier to grind an inside radius and keep the grinds square to the blade.
The tilting you see if from my horribly tilting assembly I built for my AmeriBrade. I was going to cut some angle iron as a 3rd leg to stabilize it, I am just going to buy their tilting assembly instead of redoing mine now that I have the surface grinder!
The grinder came with some little rubber feet on it. I've operated it for months with the rubber feet (while still being bolted down to the stand) and it worked out pretty well. I recently removed the feet and now have the grinder sitting on some wood blocks. I believe this slightly reduced vibration I have some "vibration footage" in the video ...
Hey guys I'm new to the forum, just figured I would post my version of the grinder in a box, 2hp 3 phase motor running off single phase220 with a Teco FM50...
Gosh I hate that static shock thing at the grinder!! I didn't read through all responses, but can tell you that it has a lot to do with humidity. At anything less then 45% static becomes huge issue in my shop, with any machine. Either grounding as has been mentioned, or what I do is a humidifier in the shop.
For those of you with disk grinders. What are you using? I'm looking at the 1 horse 9" from tru-grit. Thanks
