2102.1 | possible solutions. | SUBPAC::TADRY | | Fri Jan 24 1997 15:24 | 18 |
| Jewell,
I've always wanted one, as I hate sanding and scraping (WILL). Anyway,
I'll take it off your hands for $200.00...;*)
Anyway,
Are you taking light cuts and not trying to thickness sand? Are you
using one of those crepe(sp) sanding drum cleaners? That will help
get the crud out of your paper and make it last longer. Also, What type
of wood are you sanding? If its a softwood then I imagine it would be
a pain in the ass to use sine softwood it loaded with pitch and will
load quickly. I would also assume that your using a dust collector
of pick up the sanding dust so it doesn't re-deposit on the paper.
Good Luck and let us know how you make out.

2102.2 | Any other offers? | BSS::ANDERSON | Jewell Anderson | Fri Jan 24 1997 16:45 | 33 |

I probably have $200 worth of accessories on the sander. But I'll
consider the $200 offer made by reply 2102.1 as a starting bid for this
drum sander.
I've try to use both 35 and 80 grit sandpaper to sand down 2' x 6'
glued-up oak panels. Two problems occur:
o The sanding drum is unsupported on the open end and the weight
of the panel is heavy enough to cause the table to sag away from
the sanding drum and to rotate around the stand. It's not alot
of movement, but it's enough when you're trying to get a table-top
smooth finish. I've added a couple of support arms to help stabilize
the table.
o 3" strips of cloth sand paper are affixed to the drum in a spiral
fasion. When sanding the glued-up panel, the surface deviates alot
on the first pass. And when a high-point crosses the sanding drum,
it can cause the sanding strip to ride up on itself or tear at the
weakest point, usually the end of the strip that is attached into
the drum itself.
For me to become proficient at using this machine, I'm going to have to
acquire a better feel for height adjustment. There seems to be a balance
between making a pass that doesn't exert alot of pressure on the drum
and taking enough material on each pass so you don't spend all day
dancing around this machine.
And finally a note on design. Why would Performax design their sander
so height adjustments are made by raising the table & motor rather than
lowering the sanding drum? The weight of the sanding drum is much less
than the table and by making the table stationary they could beef up the
supports.

2102.3 | Wrong tool for the job? | SUBPAC::TADRY | | Mon Jan 27 1997 10:01 | 16 |
| Jewell,
I think, IMHO, your asking this machine to do too much. This isn't a
Timesaver (commercial unit) sanding/thicknessing unit. I don't think
thicknessing on this unit is wise at all and I don't think I would
have bought it to do so. It appears to be a small finish sanding
unit that will, given many passes, do thickness sanding in
the realm of 1/16 to 1/32". Your right, one end in hanging off in
space so there is no support/limited resistance so you will have
a skew across your board if your too aggressive. You also didn't
say what your trying to "plane" down so if I guess at a softwood
with 35-80 grit sandpaper I can see why your having problems with
paper loading. Have you tried "near" finish sanding on this machine
with something along the lines of a 120-150 grit paper?

2102.4 | Some tools live up to expectations | BSS::ANDERSON | Jewell Anderson | Mon Jan 27 1997 15:21 | 20 |
| Ray,
Make no mistake that these drum sanders are marketed as abrasive planners
and not just finish sanders. (see http://highland-hardware.com/catalog/
performax.html#37x2). I'm using mine (model 22-44) to finish glued-up
panels made from oak boards planed down to about 7/8". I don't believe
this is an unrealistic expectation based on Performax's product statements.
Since writing the base note, I bought the support rollers that go with
this machine, swapped to a different brand of sandpaper, and installed
2 additional support arms. The machine is working much better for me
although I'm still disappointed with it's speed and setup.
From rough-sawn 4/4 oak to 3/4 finished stock you have to make at least 6
passes with 80 grit paper. Your estimate of 1/16 to 1/32 inch per pass is
probably right. 36 grit was quite aggressive, but left the wood pretty
rough. I think the 60 grit paper I have on order will be a good compromise.

2102.5 | you should get what you pay for | SUBPAC::TADRY | | Mon Jan 27 1997 15:46 | 10 |
| Jewell,
I never got as far as you in terms of checking out system specs and
marketing statements. I was always seeing the tool advertised as a
sander, I must have missed the thickness planning lines. 30 grit paper
clogging oak is probably reality as you said since its very aggressive.
Good luck with your upgrades, they seem to be working. Have you tried
sanding in the 120-150 range?

2102.6 | Not too fast from the sounds of it | BIRDIE::JGREEN | | Thu Apr 03 1997 12:25 | 12 |
| On last weeks New Yankee Workshop Norm commented on his new drum
sander. Don't recall it being a Performax but what was interesting was he
made it a point of saying "after a few hours of sanding" he was able to
clean up some antique pine boards. He said he was limited to about 1/64
per pass. This particular unit had two sanding drums of different
grades.
His only positive comment was that he could spend less time with his
metal detector looking for nails to protect his planer knives. Sure
seemed like the surface plane was faster even with the metal detector.
