Homemade Drum Sander / Finisher made from grinder Part 2 V Drum Sand-Flea

[SuperJamster1]

It doesn't seem to matter. Like a jointer I guess the back side (behind the roller) could be a bit higher than the front to compensate for the amount of sanded material coming off the working piece. But its so little of an amount material, it doesn't matter. I would use a V belt system to the grinder if I was going to do it again, Too much resistance on a piece with heavy grit sand paper. Thanks for your comment. Bullnose,was just the countertop piece of laminate I had.

I noticed that the piece of counter top that you used has a bullnose on the end and that it has a lip that rises about a 16th or an 8th above the rest of the top, Does this give you any problems when sanding longer pieces? It seems that the work would have to come in on a downward angle into the sanding drum.

Thanks, It has been working fine and the slight vibration really isn't bad once I fine tune the speed. I would love to see a video of your sander, or from which shopnote magazine article were the original plans. thanks for your constructive comments.

I made a sander something like this from the plans in Shopnotes magazine. the difference is that the wood runs underneath the drum on a table made of courser sandpaper that is actually a sanding belt that carries the wood through the sander.you have the right method for truing the drum. You just might need to run through several grits of sandpaper to get it perfect.

[SuperJamster1]

Silly Court Jester! of course it was partially out of round, but it was a prototype. It actually has been working pretty well, even with that. I plan on replacing the roller but its the idea of making something from scratch that's really the challenge. I guess 20,000 other viewers have the same idea, creativity first keeps the mind sharp. Oh, and watch your language. Hee hee

[odmcarp]

it runs with a lot of vibration and it's way out of round. the roller has to run true, or your work will be all fucked up. that's what i'm suspecting....how is is working?

[SuperJamster1]

Okay, I understand. Next time I'll get a lathe, also I noticed that a vacuum cleaners roller would work perfect and hit had a center rod and tabs for holding.

[moucon]

Too bad you didn't have access to a lathe to get that drum perfectly round. The comment re: the outfeed table shim - when you remove the stock by drum sanding the outfeed then needs to be a little higher than the infeed (the thickness you removed from the stock) to correctly support the workpiece. Imagine if you were removing 1/2" at a time instead of 1/128th. Same idea.

sounds like a bulldozer.... something is out of balance.

[MrWillieZ]

Hi I noticed in your vid that when you turn it on it sounds like maybe something is out of balance

[SuperJamster1]

Outfeed table shim? Hmmm, No I don't think it does if I understand your question. Although the direct drive does seem to be working, I'm thinking now that a V belt and pulley might be better. A V-Belt slips more and that might be easier on the shaft of the motor in when resistance is greater. I also use mostly coarse sand paper, but will be getting some fine paper for more detailed work.

does this need a an outfeed table shim?

Hi,i have built an drumsander like yours and i wounder what type of velcro you used?

Best regards Tom

[SuperJamster1]

@MrTobben1971

Tom, its just 2 inch velcro, hooks side, with adhesive backing, about three feet long (depends on the size of your cylinder and length). I brad nailed the beginning and finished edge down. Cut a piece of two inch wide strip paper, and wrap it, so you know how to cut the angle of the strip to get it started and so it will wrap around the cylinder without bubbling. I used this as a template before cutting the velcro or the sandpaper. Does that help?

[MrTobben1971]

@SuperJamster1 Yes it helps :) thanks

[SuperJamster1]

Oh, that's easy. After I was done with the roller, I put a wide velcro on it which attaches by an adhesive. The sandpaper is feltbacked and made to attach to velcro.

[idc1873]

How is the sandpaper belt attached to the roller?

[SuperJamster1]

Thanks, it seems to be working okay too. But I haven't had much time lately to try it.

[GAGET4U]

Good Job. Very creative. Can't wait to see more of your work.

[formula22000nz]

cool

[SuperJamster1]

Thanks, I used it today and it seems to be working well, definitely a finish sander though. The variable speed grinder made the difference, but I wouldn't use anything under 1/3 hp. It was easy to put some velcro on it, and the sanding roll from Rockler works perfect. I have lots of velcro left, if anyone needs some. Jamster1

very nice, good job
