Hey there Simko I was wondering if you had some measurements for the shims you used behind the wheels just looking to get close without too much back and forth putting it together and taking it apart a bunch of times and getting angry I'm ready for final assembly here after paint and wanna save myself some headache

After doing three grinders, I can say that each one was slightly different.

I would get an assortment of 1/2” ID shims (0.060, 0.030, 0.015, 0.010) and start with all of the wheels with just a 0.060” shim between the wheel and the plate and enough shims to make up the extra space on the outside of the shoulder bolt. I didn’t get too technical with the make up shims because the wheel pretty much stayed in place while testing. Once I got it pretty close then I added shims to the outside to take up all of the slop. If you need to shim the inside anymore, just move shims from outside the wheel to inside (between the wheel and platen plate).

It didn’t really take too long to do each one (30-45 mins) and that was really taking my time.

Put on a low grit belt and run the grinder slow so that you can try to stop it before it runs into anything.

Start with the platen wheels and get the belt running centered on those two wheels. After that is centered, look at the tracking wheel to see how much it needs to come out for the belt to be centered on it.

The tracking wheel for whatever reason needed about .120” to get the belt to run centered on it while it was centered on the platen wheels. Doesn’t make sense because it is on the same plane as the other wheels?!?

Sorry I can’t give you any better info. Each grinder is going to be different.

Hey im about to have 4 of the Rev 4 plans cut out. Was just curious are the original DC1 bill of materials the same sizes or did you change any of those. Also do you have a diagram of what needs tapped?

Simko -

I was hoping(when you have time) could you post or PM some pics of the tracking arm/wheel assembly. I’m trying to find some pics on how this assembles together. I will continue Googling to see if I can find something in the mean time.

I got my frame parts yesterday! Had them laser cut using your Rev 4 drawing.. seems like it will need some filing on the mating spaces between the frame and hinges but I kind of expected that anyway. I am still trying to decide whether to just order all my fastening components from online or try to source them locally. I’m not a huge fan of driving all over town and would almost rather order them and have them in a few days. Haha

I’m super excited about this as it is my first 2x72 and my first grinder build!

Thank you for posting this up! I’ll post pics here when I finish my build and any comments or issues I had while assembling it.

Thanks for posting these pics! This helps give me a better idea of what's happening with the tracking wheel assembly.


Appreciate it!!
