Well Guys and Gals, Here is an update on the Thickness Sander I’m building. I have good news and bad. First the Bad, The idea of the power window motor is a bust. Turns out it doesnt have enough torque. So due to the Lack of money I will be making it a manual ( Crank) feed for now. The good news is It sanded it’s first piece of lumber today. I’ll post a picture of it with it’s sandpaper in place and I’ll post a 30 sec. video of it sanding it’s first piece. More to follow. The micro adjust system and the dust collection hood. Thanks for looking.
Lance

Pretty cool! Keep working on the feed though. It makes a big difference.

Thanks for the update. This is a great project. Looks like the manual feed crank works well. That is faster than my commercial one. I am amazed the drum didn’t launch that board across the shop without some kind of hold down. Can you gear down your feed motor and make it work? Have you tried using a car battery instead of a power supply? What holds the paper to the drum? keep up the good work.

You might want to try a motor from the sliding side door on a minivan. I have used window motors and van door motors on different projects in the past. The van door motor is a similar package size but has more torque.
I too am curious what stops the drum from shooting the board across the workshop when it comes out.

I would imagine that the 120 grit sand paper conveyor is what keeps the wood from flying. As for what holds down the paper the drum, wedges made out of Oak screwed to the drum. Thanks for the comments. and other info.

Maybe try a powerwheels motor and gear box. Can be had pretty cheaply on ebay, and with some gearing and some voltage manipulation, you could further control it’s speed. They can handle 6 volt, 12 volt, and some people mod them to 18 volt, so a variable from 3 and up could work out for you.

I have one on my drill press table now.
