I just bought a used Delta 31-255x. Works pretty good. Looks like it's been
used steady but treated well.
The only thing that bothers me is the infeed drive roller. When the bed is
raised so the drum will take off about a 64th, the wood will bump into the
drive roller and stay there until you give it a good healthy push downward
so it gets under the roller. Then it moves along just fine. As it comes out
the other side there's a solid THUNK as it comes out from under the front
drive roller and it returns to its stop.
Otherwise, the unit works fine. The piece comes out pretty even, same
thickness both sides so it looks like the drum is adjusted right, the feed
belt is tracking right.
This is my first drum sander. I haven't used one at all before. Can someone
tell me if that infeed drive roller is behaving the way it should?
Never used a Delta, but on my Jet (Performax) the infeed pressure roller
is height adjustable. Needs to be set a wee bit lower than the drum,
don't have the manual handy to tell you how much, but it isn't a lot.
Cleanliness is very important on these beasts, dust can bind up the
spring system on the pressure roller. And the head height adjusting
screw and slides can bind up in a hurry too. I blow mine out each time
I use it and use just enough lube to keep it moving freely.
Normal. Under a lot of pressure to make sure the work piece remains
flat on the table and cannot lift. Make sure you keep the feed belt
clean of dust so you don't get build up which will cause the board to
lift in spots. Support the outfeed end of the work piece if it is
heavy or long so that it doesn't snipe coming out from under that
roller. If you get snipe, a very slight upward pressure on the end of
the board may help.
Also the heavier the pass you are taking the harder it will be to
start it past the pressure roller.
Be careful not to lock up the table lift in the fully closed position,
could cause your lift transmission to slip. the X is a later model,
has some lift drive improvements and your manual should give you a
lift transmission adjustment procedure in the unlikely event it
happens. Been using mine for five years, hadn't happend, but I know
that it can, it was an early complaint.
Thanks Frank, Bill.
Bill, the roller stops on this model aren't adjustable. That threw me
for a while, thinking they'd gone out of adjustment and the roller was
now too far down. But from Frank's description that's the way it spose
I'm going to take my test piece to the jointer again, and see if I can't
get better results today but I'm still sick and reluctant to use power
So far I can't get the thicknesses at different points to within 1/64 of
each other. I was hoping to use this thing to get down to a consistent
1/16th so I could try doing veneers.
I bought it used. The previous owner said it was three or four years old
and the manual is hand-dated 08/2004.
