Sounds like you may be getting a little snipe ass the ring enters or exits the sander. I can’t advise on a fix because I don’t have a drum sander.

I watched a video using something like this sled to stop snipe. The replaceable sides are replaced with each ring. They are sacrificial to each ring. Sorry about the crude sketch.

Used to do like above, with a planer vs drum sander. I got some large flat jaws for finishing bowl bottoms, and now use the flat jaws to hold each layer and use scrapers and a flat board with sandpaper wrapped around it to get rings flat.

I used to sand the rings but now I just hot glue them to a MDF piece, with concentric ring marks, on a faceplate and scraper/sand with a flat board. Then use it to center, glue and clamp onto the base assembly using the tailstock to apply pressure. Went this route because the Jet drum sander was such a bit*h to change the drum when the glue clogged the grit.

How does your sander perform on a planed, solid piece of wood? If I were you, I would start there. If you have planer and a jointer, joint one face of a board, then plane it. That way, you are running a board through your sander that already has flat parallel faces. If it comes out still with flat, parallel faces, you know your sander is ok and your problem stems from something off in the rings. If the board comes out bad from your sander, you know where to start trying to fix things.

If you don’t have a jointer and planer, so you can’t be sure that your test board is flat and with parallel sides, try a piece of MDF as your test board.

Honestly, I use a drum sander (Performax/Jet 1632) and have never experienced the issue you are having.

It seems there’s a dip in center of the rings, so obviously from my sander. Just gotta figure out how exactly to fix the problem. Not sure if i was taking too much off a pass or the in and out feed rollers are part of the problem. Still new to using the drum sander which is part of the problem haha. Might make a new sanding disc for my lathe since the last one was on my old lathe, make sure one side is exactly flat and go from there with my drum sander. Just hate the disc method because the amount of dust it makes and I don’t have a pipe for my dc by my lathe yet.

You might have to adjust the drum sander. I check mine ever so often and make sure it’s still parallel. I use an inside micrometer to see if the drum is parallel to the table across the entire length of the drum. hope this helps.

As others have mentioned, make sure the sander is parallel to the table. Sometimes with open ended ones like my Performax 16-32 (pre-Jet model), one side will dip down a bit. Also, make very light passes with a fine grit paper and see if that helps.

Once you use the sander for awhile, you’ll know by the sound if you took a bit more than you wanted off. I usually move my piece through by hand with the sander off until it moves the drum slightly, then I turn it on and run it through. Make minor adjustments and make more passes until you get a feel for it. Once you get used to it, you’ll be able to crank it down just right, but until then, make a lot of small passes to get used to it.

-- Why waste the money buying it, when I can spend twice as much on new tools, a week online researching new techniques, and a month building it.
