I can't remember if I checked the middle of the material or not. I guess I was more concerned with it being consistent side to side. I'll run a couple boards tonight and see what I come up with.Nice detailed post(s). Thanks. :thumbsup:
I have the Performax 16/32 purchased around the time the company was purchased by Jet. Now being sold under the Jet label.
I do not have the extension tables, but even with shorter pieces which do not need the extension tables, no matter what I do the wood comes out flat side to side, but thinner in the middle than the ends. A significant depth reduction in the middle vs the ends.
I have stopped using the drum sander except for some roughing work for this reason.
I use light passes and slow feed rate.
Are you are to get consistent thickness?
I will have to check my manual to see if I can change the pressure in the feed rollers. I think I looked at that some time ago and they are just springs.How much of a variance are you seeing with yours? I know that you can adjust the pressure of the in feed and out feed rollers on my unit. Is it possible you just aren't getting enough pressure on one of the two when the material is entering or exiting the sander?
Wow that is a significant difference. Does it do the same thing at both ends of the drum? If you let it keep going, how far off do you think it would get? Also, how heavy of passes are you making?I will have to check my manual to see if I can change the pressure in the feed rollers. I think I looked at that some time ago and they are just springs.
I can easily have 1/16in thinner in the middle. I have to stop sanding or else this gets worse.

A lot of questions I know, I just can't think of what might be happening. Since it's an older model, is there any chance that something like the bearings have worn out and could be causing this?
I remember the guy at the store where I bought it saying that he recommends flipping the piece to the opposite face after each pass. This isn't always possible though if you are having to flatten an entire face with multiple passes before you can trust sending it through the other way.About the same on either side of the drum. If I continued I may get 1/8in taper in the middle.
I turn the piece between passes. I take like passes, about 1/8th turn.
The unit was purchased new in 1998 - 2000. Despite the age it has not seen heavy use over the years, especially in the last 3+ years.
Thanks Mike. You seriously won't regret it. I find myself using it every time I'm in the shop. I've since switched the paper over to 120 grit which leaves a much nicer surface, and no obnoxious snipe or tool marks like the planer leaves.Sean, great review of the machine, very helpful. Always wanted a drum sander. Might be watching for it to go on sale again at Woodcraft.
I've heard about that in some reviews. I came across a video where someone built a DC hose bracket off to the side. I'll see if I can find it tomorrow. Mine hasn't been an issue yet, but the hose hanging there puts a lot of pressure on it so I'm sure it will start popping off pretty soonTo add the only problem I have had is the latch that holds the cover on is a little flimsy.
