Wondering if someone with a kmg could help me out?:D I need to know the offset from the edge of the tool arm to the inside edge of the wheels, be it contact or platen idler. I really just need to know the spacing so I can figure out the frame setup. I also need to know the material thickness of the aluminum on the flat platen attachment. Looking to build up a grinder and want to be able to have the attachments be interchangeable and easily accessible.

I searched and searched for this info and always hate to ask other people to do my leg work, but alas here I am asking. Guess my Google fu must be off...:foot: Of course, if anyone around me has one that they wouldn't mind me taking a look at for a few I would be happy to compensate your time with some beverages of your choice.

As always I appreciate any and all help guys!

Regards,
Justin
 
The aluminum Platen is 1/2" think and they use a 1/2-3 nut to space the wheels away from the platen which should be a 1/2 thick as well. Should be a total of a 1" offset from the tooling arm to the edge of the wheel but not absolutely 100% sure.

I honestly haven't seen any kmg plans for sale, only a clone that may or may not share the same dimensions. I would be all for buying plans, however this is a completely one off design I'm building and I only need the sizes for interchangeability reference. If I have to spend 25 bucks to get this info, I would rather put it towards a platen attachment and be $25 ahead since I'm purchasing one down the road anyways. I really didn't want to do that until the last stages of the build so I was hoping someone with a kmg and a pair of dial calipers could take a peek for me please. I would appreciate it greatly! I'm sure I could guesstimate and the grinder would run just fine, I just have OCD issues and need things to be extremely exact and definitive when I build things, even on the smallest of details.

Thanks again,
Justin
 
I will in the morning . . . I know it is not exactly one inch . . . I think mine was .9375, but I will check.

I had this conversation with Rob Frink a couple months ago because I want to have a shaft turned to replace the bolt & spacer.
 
This is correct .9375

I said exactly 1 inch because I cut coupling nuts to 1 inch for the eight different wheels and attachments on my KMG and they all track right on. If Rob Frink says .9375 then that is correct. I have not accounted for how far on the jackshaft I set my drive wheel and I have three .043 machine bushings on my tracking wheel. Sorry , I stand corrected. Larry
 
You guys are awesome, I really appreciate it. Didn't think I would get an answer so quickly!

Thanks everyone,
Justin
 
No need to defend your answer. Lets face it to 95% of public .935" is exactly 1 inch. LOL

Well I can assure you that I will be copying your 1' size to have a shaft turned. Tonight when I measured I got 0.96875 . . . . :rolleyes:

Hope I didn't sound rude are contradictory . . . I had asked Rob why he didn't use a 1" precision thick bushing & he told me because his people machine those nuts to the proper size . . . 0.9375 I am "pretty sure" is what he said . .

I don't think it really matters . . .
