I have a Mikron 132 and have slowly been tooling it up. I just bought a Mod 1.25 hob so now I can make the change gears I am missing.
I am always looking for parts and info on this machine and gear hobbing in general.
I have been to those sites. Like you found, these is little info available. I understand the basics of hobbing and succesfully made some gears. But I know there is a lot to still learn!
Figuring all the change gear ratios is tricky. I made a spreadsheet to help calculate the proper ratios, but I dont have a full set of change or feed gears. I am going to start making my own now that I have a Mod 1.25 hob
