I found this old Manning Bowman 4 1/2” bench grinder on Facebook marketplace. Guy was asking $30, we made a deal for $20. I really like the looks of it, and it works, and it’s small, so it wont take up much real estate in the shop. Right after I picked it up, I swung by old reliable HF for some parts and such. I picked up a new grinding wheel, a 6” (all they had) polishing wheel that I’m gonna have to cut down to 4 1/2” and a “sander base?” looking thing that I thought I could make a small disk sander, as the sides of the grinder are open. Give me your ideas on what configuration you guys would go with. What you would put on the left, and what you would put on the right? As soon as I got home after that, I started tearing it apart. I cleaned the motor very well, and lubed the shaft up. It was caked in dust and grime. But now she’s clean, and spins like butter. Next, I started work on the case. I tried to heat up and remove the decal, but it wasn’t happening. So, I sanded it off with the paint, after I took many pictures of it with a ruler. So I can try and make a new one, or paint it on. I then primed the case, sanded to 240, and painted with the blue I paint all my tools with. The next morning, I sanded out some of the runs, dust, and imperfections in the 1st coat of paint with 1200, and sprayed on a second coat, a lot more carefully to try and avoid the runs. That’s as far as I am so far. I think I may do 2 more coats of paint, lightly sanding with the 1200 in between coats, with many coats of spray on poly after. I need to polish up all the metal parts, repair, replace any bad electrical components, and put it all back together. I’ll update after I get a little more done with it. Thanks for reading if you made it this far. This is my 1st blog post, and I’m still new to all of this, so please excuse any wrong names I come up with for parts, or anything like that. Thanks again

Oh, also it came with a small chuck that screw onto the thread shaft, after you put the nut on and tighten down the disk. I assume it tightens around whatever’s in it through centrifugal force? Any ideas what it could be used for, or what it may have originally been intended for would be appreciated. I don’t know if it originally came installed on the grinder, but I’ll defin put it back on, just cause it looks cool sticking off the side, if for nothing else. Thanks

After looking at the blue paint I put on this, I don’t know if I like it or not. I like the color. I just don’t know that it fits the style. I’m gonna leave it for now, and I’m gonna paint the “ribbed” section with either white, or orange, probably white. Maybe silver. Lol. Who knows? Id appreciate your guys thoughts? I’m gonna leave it the blue I painted it for now, but what color should I use to accent the ribbed sections? If I ever do repaint it again, I think going back to the original color would be best
