Hi folks. I just picked up a Delta Horizontal metal-cutting bandsaw. I
see that these are typically described as 6x8, 7x11 ect. What exactly
do these dimentions refer to?
My machine is a model 20-900, serial # 8613915 and is missing the motor
and an expensive looking variable speed pulley (looks kind of like a
I got the saw out of a dusty corner of a shop for free. It is pretty
rusty, but the bearings in the wheels, and gearbox seem ok.
I found an exploded diagram/parts list from the Delta website, but no
owners manual. The folks who gave it to me say "that thing was a POS
from day one!" Hopefully they are incorrect.
Do you folks think it is worth fixing up?
Thanks, Andy Hall
According to andy :
The smaller number is the maximum diameter (or thickness) which
can be cut before the workpiece hits the frame and stops the cut.
The larger number is the maximum width of workpiece, defined
both by the maximum separation of vise jaws, and the maximum unsupported
length of blade between guides.
That sounds like a good start.
For light duty, it probably is. You may prefer to use step
pulleys as a cheaper way to rebuild it. The original motor may well
have burned up -- this is a problem with some of them in heavy usage.
You can probably make it better than it was from the factory
with a bit of TLC.
Is this the equivalent to the $199 green or blue taiwan/chinese cheapie most
of us have? 4x7, iirc.
If so, keep this figure in mind ito your parts bill.
Is it worth it?
Maybe not for that particular saw, given the price of a new one, but they
are *extraordinarily useful* tools to have in a shop. You can also use them
as a limited vertical band saw as well (1/2" blade, which will limit detail
cuts, altho I think you could proly mount scroll blades as well). The
"table" is absolutely miniscule, but you can enlarge the platen quite a bit
without interfering w/ the horizontal mode--to about mebbe 3" by 4". Some
table, huh? :)
Also, the asian imports have various quality levels. Mine is a real dog,
but it works, for years now. I saw it's clone from MSC, the same price,
much better quality, at least appearance-wise.
I would also consider welding a decent angle iron frame, w/ casters. I also
bought a "work roller" stand from HD for $20, for long mat'l, which helps
When shit breaks off/falls off my saw, my supplier gives me parts for free,
as he has a mountain of rejects/parts rusting back in his warehouse--the
perks of buying local. :)

All good points.
Yeah, the MSC unit appears heads and shoulders better than mine. And MSC
has a helluva markup, so you can imagine what they get the saw for.
The sheetmetal legs are certainly stable;
I mention the casters in the context that the saw *appears* light and
portable, but when you actually try to move it, it's heavy like an SOB *and*
unevenly weighted, making it surprisingly difficult to shove around. I've
wished many times I'da put the goddamm frame and wheels on it!
Also, w/ a custom frame you could put a shelf or two for blades,
miscellaneous items, etc. Also a chip-catcher is nice.
But most of all, I'd like to put a Little Giant pump on there, for some
coolant. Be still my heart...
That's where a good stand would come in handy, w/ a sheetmetal coolant
I think there's part of an FAQ devoted to this style of saw, no?

Thanks for the replies.
I figured out that my saw is a model "7V" and is a 7x11 sized machine.
It is made mostly out of welded and folded pieces of steel rather than
castings. I found one on ebay, and it says the motor is 1/2 hp. This
sounds a little light to me. I think this motor may have been
specified due to the capabilities of the variable speed pulley (after
looking them up on Lovejoy's website).
I may end up using a larger motor and fixed pulley and just have one
Overall, the machine has a sort of "chintzy" feel to it. but I will
enjoy myself getting it back into shape.
Don: what do you mean when you suggest "fixed pitch font" I apparently
am not using it, because your sketch doesn't look right. I read the
group with Google Groups.
I understand what you meant though as my wheels have a shoulder on them
that the back of the blade runs against.
