Delta 1426 12" direct drive disk sander with Breuer Electric Tornado dust collector vacuum fan.
The (1/2" x 3" with 2-3/4" on center drive screws) serial number tag is missing but the outline can be seen in the paint.
The logo tag is Delta Milwaukee.

It appears that the dust collection spout and Tornado fan was added later.
There are some small tapped holes around the lower guard outlet--I'm guessing that metal ductwork was originally connected to the outlet.
Judging from the swarf and lack of sawdust, this sander appears to have been used exclusively for metalwork.

Motor: Delta 3/4hp, 110/220V, RI, 1725rpm, dual shaft with guard, ~70#, currently wired for 115V operation.

Stand: Delta bolt together style.

Delta 351 caster set: Cast iron wheels, brackets, and pads.
Two lengths of iron pipe with a coupler slip into the holes of the brackets--both ends capped.
You slide the pipe forward and use it as a lever to tip the stand back onto the wheels.
It is a bit awkward but matches the vintage of the sander.

Dust collection: I originally attached the Tornado, but later removed it and fabricated an adapter for my dust collector.

>>HISTORY<<
Mid-1990s:
Here is the machine that started me down the OWWM slippery slope.
I found it in a dumpster.
The sander included a later model dust spout with Tornado dust collection vacuum and bag.
The original stand was damaged beyond repair, the dust bag torn up, and the motor was 3-phase, so I left all three in the dumpster.

I disassembled the Tornado and removed bits of metal.
After reassembly, it powered up and ran well.

I was able to get the owners manual from Delta and I began searching for a suitable motor.
This sander takes an 8-1/2" frame motor with a 3/4" shaft.
The only motor I could find that fit this sander was a Baldor NEMA 66 model L3566M, which listed for $425.
So the sander just sat in pieces in a box.

Fall 2001:
I was sitting in front of a computer and I thought of the sander.
I Googled "motor Delta disk sander".
The first hit was www.owwm.com
Once I entered the site, there was no turning back!

2003:
I posted separate requests for a motor and stand.
I bought the motor and stand from a fellow OWWMer located in California.
I left everything boxed because I was in the process of moving again.

2005: Found an old style Delta caster set on eBay.

2007:
While purging clutter from the workshop, I notice the milk crated motor and three boxes with the sander, stand, and casters.
I've carried this sander (parts in boxes) through two house moves, for more than ten years--why not assemble it?
Overall the basic sander is in nice shape and runs well.

2014:
Up until now, I've used this sander exclusively for wood working.
But now it is used exclusively for metal working.
