The Rockwell belt sander is completely apart. Very glad that I did as well since the lower bearings were pretty bad and there were a lot of loose bolts and screws. The base is a bolted together assembly so I opted to pull it completely apart and paint it in pieces. The sandblaster is getting lots of work these days.
This is the before of it. While I have it apart, I'm going to change out the motor for a 1 HP that I happen to have. I thought that it was a 1/2 HP but it's actually a 3/4 HP. Someone was saying that they had up to 2 HP in them.
This is the motor that I'm going to run in it. It's actually new but has been stored poorly.
The unit is much better built than I had originally thought. The drums looked like they were thin stampings but once it was apart, they are actually fairly heavy walled casting. Not sure if pot metal or aluminum but they seem strong. I'm used to the machines with 1/2" walled machined aluminum drums from billet.
The paint was very thin and blasted off easily. My sand media is quite fine since I don't mind a bit more time on it rather than damaging my parts.
The screws for the base are interesting as I've never seen this style. Obviously for sheet metal with dimpling and they seem to be a good design. They cleaned up nicely on the wire wheel and have a bit of a luster to them.
Once I got the bearings apart, I realized that it might be a problem finding them. I hadn't thought about it but they would definitely be older style inch bearings. As it turned out, I had them in stock. I had purchased a whack of bearings a few years back from a motor guy that retired. I had all four that I needed.
