Mauser rifles have a buttress thread where the gas shield fits into the back end of the bolt. I've got a special tool bit stashed away ground to turn that thread when I need to fabricate a copper heat sink to protect the threads when I'm welding on a custom bolt handle. The thrust bearing face of the thread is angled at 5 degrees, and the other side is 45 degrees. The thrust of lifting the bolt handle and compressing the firing pin spring is carried by the flatter angle. There's no really good reason for it, as other, less sophisticated rifles use a conventional 60 degree V thread on the bolt parts, but Paul Mauser over-engineered everything about his designs- - - - -way back in the late 1800's!

I have had great luck with my old craftsman “block grinder”. I bought it used and cleanedxit up and replaced the cord. Its from the 60’s and runs great all the time.

Weird, my 3/4hp 8 inch Craftsman grinder I bought used 30 years ago died yesterday. It uses an obsolete starting relay that I tried to repair by cleaning the contacts, but it still won't go unless I give the wheels a good spin to get it moving. I hate to give up on it, but maybe it's time for a newer one after I get tired of spin starting it.

The capacitor has crapped out on it. That relay runs power thru the capacitor for starting, then takes it out of the circuit. Is there a cylinder on the side of the motor or maybe under the base? That's the start capacitor.

My grinder does not have, or use a capacitor. It uses a Klixon 4CR starting relay in series with the start/run windings. It also needs to be an exact match for the motor size too. I don't know if I want to go to the trouble to find a pricy replacement and have it still not work.
