Thanks!

I’m looking at a very nice Baldor motor for sale to fit up to my disk grinder. Problem is, it has a 7/8” diameter drive and I need to find a keyed adapter/coupler that will step down to a 5/8” OD to attach to my aluminum grinding disk. Haven’t been able to find the right part. Any suggestions...

1200 f for an hour?? Hmm, never heard that before. Interesting.

I think I'm experiencing information overload! I guess I need to define my terms and perhaps rethink my Heat Treatment procedures. I have watched videos and read articles/posts that would suggest normalizing grain structure is a good practice prior to hardening (Austenizing), for forged blades...

My understanding for stress relief, you bring it up to critical temperature, at least from what I've heard. Thanks

I wonder how much longer...

I have a set of 1084 blades that are in need of stress relief prior to heat treat. I plan on foil wrapping them to minimize carbonization, as my blade tolerances don't allow for much more steel to be removed following heat treat. To relieve stress, I follow a three step process of bringing the...

I took some time to realign the motor, and believe that may have solved the problem. I’ll know more when I begin my next grind tomorrow. But it doesn’t move like before when applying pressure to the platen. Regarding the crown on the wheels, I misspoke before; the drive wheel and tracking wheel...

Ed’s astute observation could be the answer to my problem. The motor is mounted on a wooden bench and is attached separately to the machine. I’m thinking it might be slightly off in alignment with the machine. I’ll check it out and report my findings. With regard to the spring cylinder that came...

Thanks for the feedback. I’ve wondered about replacing the piston myself with a heavier duty one.

I’m trying to decide if the belt sliding on the platen when applying pressure while grinding is an equipment or operator problem. I have an Origin Blademaker Grinder with a one horse power motor. The wheels are all crowned and aluminum with the exception of the top platen wheel, which is a...

Final product. Turned out pretty good. Thanks to all for your help along the way.

Well, thanks to everyone’s helpful suggestions, I finally settled on Jeremy’s pinging the guard technique, seated with JB Weld. Nice, tight fit. Very satisfied with the results. Thanks again!

Hey Jeremy, I really appreciate you taking the time to share some of your techniques! Thanks!

I might try pressing again with my vice.
