The last two weeks I’ve been gathering some of the materials and prototyping some of the parts.
I picked up a 1.125 HP two speed pool pump motor along with a hand full of pulleys and belts for only $22 on Craigslist! I tried to give the guy $30 and he wouldn’t take it. What a steal!
Does anybody know where I can get a custom sander paper belt made? It will need to be about 16” wide x 66”.
Using 1.75” OD PVC I made the conveyor pulleys. I used a hole saw to cut little blocks out of maple that fit perfectly inside each of the PVC pipes.
For these I used steel pipe instead of rod. I don’t think it needs to be as strong as the main drum.
I was thinking of putting a layer of rubber on the pulleys to grip the back of the sand-paper conveyor belt and keep it from slipping. Does anybody know if that would be necessary? My belt sander just has hard plastic rollers so I’m thinking the answer is no.
By looking at other people’s designs I figured out how to make the mechanism that will put tension on the conveyor belt. Before I spend a lot of time machining aluminum I prototyped it out of some scrap oak this evening. Seems like it will be a pretty straightforward build.
This week I’m trying to finish the conveyor table, but I don’t think I’ll be able to since I don’t have one of the sprockets I need yet. I can do the rest of it I guess.
Thanks for looking and any advice you’ve got I would appreciate. You guys always think of things that I miss.
