18/36 drum sander question

[naveall]

i have a question about my 18/36 delta drum sander. when i feed my wood in regardless of the speed it will stop the top drum from spinning and i have to lower the bottom down to get the wood to feed through, i have tried feeding from 3 bfm all the way to 12 bfm and it still stops the upper drum. this happens on every wood i use from pine to oak, what am i doing wrong, i set my top drum so it barely sands the boards or say less than a 16th of an inch and i can still stop the top drum then adjust up as i need to with each pass. i know there is something i am missing i just do not know what, the problem i am having is keeping the lower belt tracking correctly, i adjust according to the instructions and it still rotates towards the back of the sander, my adjustments are in the front on the infeed side

any help would really sped up my work, i do have it connected to a 2 horse dust collector

Hi Naveall
What causes the slipping has to found before help can be on the way. The drum has a two speed pulley, with a belt that has a tightener on it.
The drum sandpaper has to be tightly wound, and the spring holder clamps must have tension on them to keep the sandpaper tight, or the sandpaper could bunch up and stall.
Check the drives that the keys are in the pulleys. You need to find the slip to fix it. If you overload and it is working right you should stall the motor and knock out the breaker.
Hope this helps you find the problem.

I agree with Norman, you need to find out where the slippage is.
If the top drum is belt driven, it may have stretched or dried out.

ok,

have to ask this one, how do i make sure the paper on the top drum is tight enough, these directions are very vauge in the book that came with the sander and really do not address this or how to even put the paper on the correct way, my guess is the paper is loose on the top wheel, i have it running on the fastest setting and run the lower belt on 7 feet per minute, most of the stopping is when the wood is a fraction different than the rest of the wood, i can even stall this out running 1/8 inch baltic through the sander i have only triped the beaker once and that was right after i got it and was playing with some scraps to see how it worked, if i ask please forgive me as i learn a new toy.

so far my jionter has worked perfect, i used it today to reduce some body parts on a cougar we are making for a customer here in town, took off 1/16 at a time and the jointer kept right up with me, i am waiting for a floor so i can hook up the delta table saw (unisaw x5) we got, it is a five horse induction motor and i have to wire the shop for it since it is 220 and that extra 5 feet of table on the right is going to really help when we are making our blanks for our portraits, not sure how or where it will end up, all togather the table saw is seven feet, 6 inches long and according to the packaging when put all togather weights about 900 pounds, and it is really hard to move around we have to get the lift that goes under it

Hi Naveall
Sorry to hear your problem won't fix itself, mine never do either.
I install the sandpaper starting in the right clamp, rotate the drum top side forward pulling the sandpaper around the drum untel you get tothe left side clamp. Put the taper end in and squeeze the clamp open and push the paper far enough that the clamp cannot return back to lower side of the drum. The spring in the clamp should apply a pull at all times. When you use it check it
right away, if loose thighten again, as machine will pull the paper tight and your left side clamp will loose it's pull. All sanders must be used with strong dust collecter system.
Tip; The board entering must be level going in and (high) level comming out to prevent snipe.
Hope this helps or someone else can explain better.
