Hey guys,

I got a used performax drum sander https://www.fastenal.com/products/details/0953537 a few months back and it works great!

When i got it the conveyor belt was slightly warn on the right side (closest to the motor) which means that it was not aligned properly and was rubbing against the shroud. You might be able to see in the attached picture.

As you can see by the first picture i had aligned the conveyor to be equal on both sides but over time it started shifting towards the right. I’ve tried adjusting the belt tension to get it to go to the middle but it keeps going to the right.

has anyone had this issue? i can’t keep messing up the conveyor or wasting time realigning after every use.

That’s awesome! i’ve been looking into it like crazy and i know i’m not the only one. I am tempted to get the rubber belts since a lot of people say that’s what they get and it fixes the problem. But i’m really hoping someone here has had the same issue and can help.

I’ve adjusted those multiple times and am still having the issue… I wish my belt looked like yours…

Some tips:

1. Check and make sure the conveyor is lined up to the drum correctly. There’s not a lot of play, but the drum head should be perpendicular to the conveyor bed.

2. Check the alignment of the black conveyor drive roller. There’s not a lot of play, but make sure the roller is straight and square to the table sides. On the outboard end, look for worn/missing brass bushing on the outer end or bent mounting plate. On the inboard side, the motor and controller box can be shifted back and forth just a tiny bit by loosening the mounting screws.

3. Check the idle roller end, check for bent mounting plates, bent screws, make sure the plates move smoothly when adjusting.

4. Loosen the idle roller until the belt won’t turn and then check it for square to the table. Then start tightening the belt a little at a time until there’s just enough tension to keep the belt moving. You can over-tighten the belt. Try doing the reverse of the instructions, instead of adding tension on one side, try loosening the other instead.

5. Pull the belt off and rotate it. The belts can get stretched with aggressive tightening and if the drift direction switches when you rotate the belt, it might be time for a new belt.

6. Check the ceramic tracking guides under the bed and make sure the belt is in them. I’ve seen lots of people say they don’t work and they definitely won’t keep a poorly tracking belt in the middle, but I think they do help with minor drift issues.

Good luck,
Mike

My Delta also did that, it looked to me like over time one side of the belt stretched a little. Regardless, your feed belt needs replaced…I’d get a new one and try to get it adjusted.

My original 16/32 belt was always a pain to adjust, but with lots of tweaking I was finally able to get it running true. The seam was giving me grief when sanding boards where I wanted a dead flat surface end to end. The seam being slightly thicker was leaving a divot (a lot like the usual snipe problems) if it passed under the drum while sanding.

Eventually I bought a “plastic” replacement belt without the glued seam. Setup was easy and the seam problem disappeared. When clean, it gives a better trip on the boards versus the original belt, but with any dust it gets a bit slippery. I’ve learned to keep downward pressure on the board as it passes through (simple enough) and all is well.

If the board slips while feeding (stalls), it will show a small divot where the drum removed the extra material.

The plastic belts were not cheap (about $60 on Amazon maybe 8 years ago), but well worth it for my uses.

the one i picked up last summer to replace my delta is a winner, i had left it in the back of my truck whilst i had lunch at a local establishment, when i got home and unloaded the 100 plus degree temps has loosened the joint glue and released, and so had to wait till a new one arrived to try out me new sander, and then once new one arrived, get it installed and adjusted, took some patience, but eventually got it squared away, lots of loosening, tightening, cussing and then almost like the sun coming out on a cloudy day, it all worked out,

Biggest issue i learned the hard way was to ensure the belt clamps on sanding strips engaged correctly, it can be deceiving and once you turn it on, boy howdy it comes loose and makes a racket and if lucky can salvage the strip if end isn’t damaged too bad, only happened once, scared the be jeebus outta me at first.
best of luck, just takes some time to adjust

I know we’ve been talking about the conveyor belt, but I just noticed in the first pic you have the dust port necked down for a smaller shop vac connection.

This will work ok for small narrow boards and very light passes on bigger stuff, but if you really want to get the most out of the sander you’re going to need a minimum of a bigger shop vac with a 2 1/2” hose or go to a full DC setup with a 4” hose. Even one of the small portable 1 HP blowers will help if you don’t have a bigger setup.
