Drum sander question.....sandpaper?

**doggadog** · 28th November 2014, 07:58 PM

hi all....just building a drum sander ATM. What I do need is some info on what people use re abrasive sheet/belt etc to wrap around the drum and how to attach it at the ends. I think a hose clip might do the trick but can anyone suggest something better. Thanks in advance....Graeme

You are probley asking in the wrong place on the forum.

There have been a few drum sanders built before.
I'll see if I can find the links.

If you are wanting to use it to reduce the thickness of the timber, use a course grit like 80 or 100.

If you are wanting to just smooth the surface, use 180 or 240.

Sandpaperman sells long rolls of cloth backed in differing grit sizes

I built a drum sander about two years ago. All my pics would be there under my name. On my drum I attached adhesive backed velcro. Then bought the rolls of sandpaper with the loop back to grab to the velcro.

I only use the 120 grit now And my drum sander works like a charm.

hi Paul. I thought the 100 grit might be the go but now I`ll have to consider the 120. I also decided to go the plain cloth backed roll. I am actually making the final cut over the drum today. At the mens shed where I go they have a metal lathe and I will do a power feed run to get a dead straight drum.....yeehaaa. I miss my metal lathe...went when we moved..

cheers, Graeme

Wow thats a very accurate way to do it.

Mine is rough as guts compared to yours, I followed the idea discussed on various other builds of creating the final drum surface by mounting a big sandpaper block on the table and raising the table to kiss the drum - that guarantees that drum surface is parallel to table - drum could be slightly tapered but it doesnt matter.

SteamingBills method of drum levelling works a charm. The parallel-ness of the drum to the table is super super important.

Although mine is a second hand carbatech, I took the time to shim it using slivers cut from coke cans. They are very flat, very uniform and exactly 0.25mm.... shimming up, sand, measure board thickness both sides, repeat until its dead accurate on both sides. Doesn't take long.

Making one is highly satisfying and there ar some extremely good threads, plans and videos out there to do so.

Been waiting for some pics to appear

I guess it has to be on my to do list also since I started this CGB thing. I have mulled over the idea of running a drum on my lathe but the hastle of setting up and taking it off again for each job is holding me back. I am now thinking that one of those very basic GMC lathes may be the base to build a drum sander around.

You might find this Youtube video interesting ...... https://www.youtube.com/watch?v=tUJi...klww1YojZN-KiQ

The video was released only in the last day or so. His design for the Drum Sander that he discusses in the video has some interesting features - in particular, how he addresses the issue of changing the sand paper quickly between different grades. Personally, when I get round to building one next year I'll opt to use steel for better rigidity, less slop in the mechanism, etc. Not sure that I like this guy's use of MDF for the structure, but then he is designing it for woodworkers to build. The main feature I like about the drum sander in this video is that he has combined conveyor belt feed drum sander functionality with a SandFlee style sanding table on top of the drum.

Regards,

Roy

I was going to do the flattening with a sand papered board until I thought of the metal lathe and I think the lathe will work well. Murphy`s law prevailed yesterday however as the metal lathe was busy then not working....daym. Anyhoo, a friend there has a lathe and I`ll do it there...beauty. cheers, Graeme

I plan on using paper shims to level...if I have to ...should work ok.....cheeers Graeme
