  • As some of you know, I have wanted to stop managing H-M for some time. It's a tremendous strain on my personal life. I want to set up my own shop. In September, September 15, to be exact, it will be 8 years that Hobby-Machinist has been in existence.

    I have been training VTCNC to run things here. Dabbler is going to learn too. I feel that they are ready to start taking over the operation. I will be here to help in case they need, but I don't think they will. Tony Wells is and will be here also to consult with. I will be doing backups, upgrades, and installing addons. Other than that, I will not be around. I am leaving this place in good operating condition, and financial condition.

This is not a new subject. These grinders are known for their poor quality wheels and sticking tool rests.
I replaced the grinding wheels with one diamond and one good quality “green wheel”.
I followed the advice from YouTube to make this Baldor knock off worth a darn.
Squaring the protractors, removing paint where it contacts the sliding protractors, removing burs and providing clearance where. Required.
I assumed, “type 50” grinding wheels would fit this machine since the manual’s Instructions did not say, modifications required. No, I had to remove about .010” from the aluminum backing plate on the well made diamond wheel. I also had to increase the ID of the CGW wheel for proper mounting clearance.
Just be aware, I was expecting to perform these upgrades. I have a very smooth, capable machine now.
I saved hundreds of $$$$&$ but I did have to spend a few hours on it.

Very nice. I hope to find one like that one day. All that import stuff anymore is bought in "kit" form, huh? Good work!

I must be honest. Shadon HKW, otherwise known as the “Bash” host, did a repair on his baldor 510 tool room grinder.
He made a tool path on the grinder and surfaced his grinder wheel backing plate at 3,500 rpm.
I am obsessive compulsive, I noticed a bit of runout on my cheap Baldor knock off and decided to surface my face plate just like my YouTube Mentor.
It was 5:45AM, the screeching howl was so loud it reminded me of a concert in the 70’s where I was lucky enough to stand right next to the speaker mountain.
My wife came running out of the bedroom out of a sound sleep!
“Are you out of your f#$@;!!ing mind??
I have to tell you, the runout is gone!
I clamped a parallel to the cast iron table. Used one of my Phase II QCTP holders and HSS bit.
I probably should have used carbide. But, it worked. My ears are still ringing.
I overheard my wife talking to my oldest son, “he gets up at 3:00 and goes out to his shop, he goes to work at 5:30. When he gets home, he changes his clothes, goes out to the shop until dinner. After he eats, he goes out to the shop until bed time”
My son said, yep, sounds like Pop.
