I just purchased an almost new General 15-250 drum sander after doing the i nitial drum set up I cannot get the rear drum on the right side to raise en ough I have it level but I cannot get it high enough so as for now the fro nt drum is not touching the wood at all Is there any more adjustments I need to do Thank you Jim
I would think so, since it isn't working properly. If you have done the below adjustments correctly then there is a problem. Is the front Drum parallel? If you don't see anything obvious I would call General International. ~~~~~~~~ From the manual...
For optimal results, the rear drum, ,should be set fractionally lower than the front drum, ,by the depth of the grit of the paper on the front drum, .
- The front drum is factory set parallel with the conveyor table and needs no further adjustments.
- The rear drum is micro-ajustable. It can be slightly raised or lowered at each end and must be kept parallel to the table.
ADJUSTING THE HEIGHT OF THE REAR DRUM To set the rear drum to the correct height proceed as follows:
Note: To achieve parallelism with the front drum, any gauge blocks that are used (whether purchased or shop made) must be a matching set and must both be at the same height.
Note: You will not get an optimal result if the rear drum is not low enough. On the other hand, attempting to remove too much material in one single pass may result in workpiece burn problems or in motor overheating.

I adjusted the drums as directed in the manual but the right side of the re ar drum will not adjust any higher As now I can?t get the front drum to touch the material without cra nking the feed table too high and stall the feed table.
Any tips ? Thx Jim
OK - things were working - the front drum was touching the material - then you started making adjustments - and - now you can?t get the front drum to touch the material without cranking the feed table up too high and stalling the feed table belt because the rear drum is too low.
Why were you adjusting the rear drum?
To be of much help we will need more of the story
rear drum will not adjust any higher
cranking the feed table too high and stall the feed table.
When I bought the machine recently it had no sandpaper in it so I followed instructions in the manual applied sandpaper to the front roll I just did it to my blocks that I just did the back roll but in order to get it I just did parallel to the front row I needed to raise it up . The left side of the role I have lots of adjustment up and down but the rig ht side on the microwave just screw it will not come up high enough It seems that I ran out of adjustment on the right side when I tried bringi ng it up 1/8 of a turn to allow for sandpaper grit The machine works fine but when I ran material through it it was only sand ing on the rear or secondary drum the 1st drum is not touching Thank you for all your help

General is a real outfit; I suggest contacting them directly.
I've no personal experience with their machine so can't comment directly on just what might be the specific cause behind the symptoms altho perhaps the previous owner did something to cause an issue? Do you know whether that person ever had it set up correctly or not?
I?m not sure the machine has only been used just a few times it is in new condition there was no paper on it when I bought it he was an older gentleman that had it , it was out of adjustment when I bought it so I we nt through the procedure of setting it up as specs call for but I cannot ge t the rear drum on the right side to adjust high enough I?ll go bac k and work at it more tonight Thank you for all your help Jim

Hey, here are a few periods:
. . . . . . . . .
It appears that you have run out, so I'm willing to share some of mine.
You're welcome. ;-)
Well, on occasion even the good manufacturers have a lemon so you can't completely rule out there was an assembly problem...or that it somehow got damaged in shipping or the like.
I'm not sure whether it was shipped fully assembled from factory or whether required some user/dealer assembly; there's another place something could have happened if so.
Or, could have been mishandled anywhere along the route--it's a large machine so opportunities there for somebody to have slung a sling (so to speak :) ) under the drums and lifted, for example, bending a shaft or the like.
Just all kinds of possibilities besides perhaps just a simple oversight of some sort but that is impossible to diagnose remotely without the expert from the factory.
Did the elderly gentleman indicate it ever functioned properly--or would he have even known?

I don?t believe there has been any shipping damage that I can see the older gentleman was a machinist who is now in a home unfortunately that is one possibility I had not thought of though I will do some further inspections on the drums and the level of the table to make sure nothing is bent that is a good thought thank you
