I always love to see people tweak things to suit their needs. Well done. You didn't mention the tool arm slot. I really like that. I might have to make one for mine.

Thanks for sharing! I like the gas shock. I've never worked with them, and I like how that turned out. It gives me ideas.

Would you mind if I saved your pictures and added them to a FAQ on my site? All credit will be given to you for them.

Have at it! Now you know what I did with the extra upright.

David,
Did you use the same parts on your KMG? I would like to modify my KMG clone also.
Thanks,
Fred

David responded to my email that the part numbers worked for the KMG as well. I ordered a set for my clone today.
Thanks again David.

Thanks, both of you. I have used duct tape on one of my wheels as a temporary fix, some time ago. Worked fine.

Parts arrived yesterday and I installed them.
The grinder sounded different as I ran it through different speeds.
I did not have a chance to do any serious grinding because I had a whoops moment. I managed to snap an 8-32 tap in the tracking and tension arm and had a heck of a time getting it out.
I should have switched to another type of tap holder, but was in too much of a hurry. So it took 3 times longer.:(
Thanks again for the info!

David, your grinder mods got me motivated to get the Fellhoelter inspired gas tension going on my NWG. I advocate the NWG for people with some fab skills - I love it's versatility and I would be happy to put mine up against some production options, but, like you, my next grinder will most likely be a GIB with variable speed. I got the parts you listed for the piston but knew I had some geometry to work out as we have different machines. My parts have been sitting in a drawer for some time. Today, I got off the horse and chopped some tubing off the top end of my grinder (back of the tracking arm - mine was longer than most) to get the gas piston to fit. It fit - tracking went to hell. Way too much angle in my tracking arm for the tracking adjustment to work. After a moment of silence and another type of condolence, I got the welder and some scrap iron out. I put an upright on the front of the tracking arm to accommodate the piston. Now, the thing tracks and responds like a dream, but I will swap that 20 lb piston for a 40 lb one when I have a need to order from MM Carr. Thanks for sharing your build. EA

World's first coil over spring on a gas shock for a grinder - or maybe not, I have no idea. It rocks. EA

Funny... I just ordered a 40lb from McMaster-Carr today. My 20 seemed a little soft for one of my grinders. I like your set up Erik.

Ha! My piston is too weak for my GIB too. I moved my tracking arm out and swapped the rear spring for the piston but it was NOT enough weight. Impossible to use. I moved it back to the original mount and added the rear spring again. Now it runs and tracks great. Piston in front pushing up and a spring in back pulling down.

I only have a 1 1/2 hp motor and its only bogged down on me a couple times. Im not sure if I read it in one of Brians posts but who uses a rubber drive wheel, Im thinking about getting one?

The first person i know of who uses rubber drive wheels is Brian Fellhoelter. Beaumont know sells them.

I have 20lb gas springs on my GIB and KMG, work fine.

Wat is the reasoning for using a rubber drive wheel! I chatted with a grinder maker on another site and did not get the answer I expected. Thanks
