Picked up two grinders today. Found both on local craigslist.
First is a 1940s craftsman 1/2HP. Model is S4150. It was $20.
As seen on CL
Mostly original. Missing one guard cover (and studs/nuts to attach) and left shield isn't original.
Vintage craftsman catalogs show it in late 30s / early 40s as PN 99 PTM 2609. Mine show PN S4150. Was $32.95 back then or over $500 in 2015 dollars.
During disassembly two bolts snapped while removing and had to be drilled out. This turned into an adventure as the drill bit snapped too and I had to work it out. Finally I got small drill through and worked up to bigger sizes and another bit snapped just as the hole neared completion. Before I knew it, it was 6 hours later and time for a late dinner.
Bearings are shot. Original is New Departure 1204 which is same as 6204. I happen to have a set of Nachi with rubber seals (6204 2NSE) which I ordered for another project but I'll use them in this as the other project is a while from completion.
Original paint is light blue for base and center band and black for end caps and guards.
Large 10 MFD starting capacitor is made by Aerovox. Amazingly still in business. I clipped soldered wires to remove and will resolder once reassembled.
If anyone has side guard cover or original bolts please let me know.
Any thoughts on paint? I'm inclined to leave it as-is and just replace cord and beatings and clean it up. But since it is fully apart it may make sense to blast and paint. Otherwise I'll wire brush loose rust off and call it done.
Looking at parts on either side I suspect someone was in here and assembled wrong. Here is what was on each side
Main difference is left side has spring washer then large washer and right side had two smaller washers and then large washer but no spring. Should I get another spring (source?) and move on smaller washer to other side to match sides?
Here is what vintage hardware looks like. Never saw a slotted acorn nut before.
Then today I picked up a Stanley 1/3 HP model 667 on Craftsman stand. This one included lighted shields too. Cord is dry rotted and needs to be replaced. Bearings are good and it is in nice shape. Seller was asking $110 but it was listed for 3w and he accepted my $80 offer. And hour later I loaded it up.
I plan to sell the stand and should break even or better in the grinder. Plus I'll replace the cord and try to get missing slide from sharpener attachment or remove it.
