I picked up a 1930s P&W R6 Tool and Cutter Grinder in the last several weeks (what isn't vintage in my shop).
Looks like I might have a contract with the local Tech School where I've been taking machine tool and machine trigonometry classes.
Evidently they've been having difficulty finding someone who would take the HSS end mills that the entry level students would inevitably break, and sharpen them to their standards, and meet deadlines. I've contacted an account/attorney and am setting up an LLC (yes, it looks like this is for real). They intend to come out to my shop and show me how to use the Tool and Cutter grinder at no charge, if I agree to take their contract.
If you can wait a few weeks, maybe a month, I should be able to help out at the same price, whatever that ends up being.
If interested my email:

I've yet to establish a business name or business email. I too have a 30s r6, I have a follow finger for flutes and a little gear motor with a rubber vacuum belt for turning ods, it will grind a ball nose or corner radius on endmills almost perfect.
Please delete this post if it violates HM rules/policy.
