From what I understand, Delta did not keep serial number records on Unisaws prior to 1941, but there are clues in some of the specific design features that may help to date the machine. I recently picked up just such a saw that appears to be in great shape and needs no parts, but I would like to have a close approximation of when it was manufactured for my own reference. Any ideas on what specifics that might help date my saw would be greatly appreciated.

If you have a Unisaw mfg’d prior to 1941, works as it should and it needs no parts it might be time to stop and get a lottery ticket.
Great find !

Delta has serial numbers all the way back to the 20’s. Used to be if you had a casting number they would tell you what year it was manufactured in, but now, as with all things that is no longer available. Go to OWWM.com and you’ll find your information there. Have fun, make some dust.

Well I checked out vintagemachinery.org and there was an article dedicated specifically to dating vintage Delta. “Delta only began keeping records of serial numbers after 1941” on http://wiki.vintagemachinery.org/DeltaSerialNumbers.ashx put a damper on my search. My serial number plate matches that used between 1939 & 1942, but my serial number predates those where data is available.

[Chanting] PICTURES PICTURES PICTURES!

Those of us in the old uni club demand pictures.

Have ye a 4 footer?

I thought about that after my last posting so I snapped a few pictures. The thing I’ve noticed about those that were made very early on was the presence or absence of a louvered dust door and whether the base was solid around the perimeter or had four feet cast into it. I don’t know if these are genuine indicators of specific years or not, but someone with more experience than I could probably shed some light on when these features were incorporated into the design.

Just from looking at it: the switch isn’t original. The uni came with a nice cutler hammer switch. My uni didn’t have it eiither. On OWWM they go for around $50 a piece, give or take.

The cast vs 4 foot uni: I believe that in 41 some of the earlier saws had 4 feet, the rest had a solid plinth. So, assuming the saw as a whole is original, it is possible for it to be a 41. Check my years on vintage machinery.

Real nice get. And it wasn’t hacked to take a non-bullet motor.

So it didn’t come with the dust door? Become friends with BOYD over at OWWM. You can get anything you may be missing from there. BOYD is the classifieds.

It does have the dust door, forgot to photo that. The goose egg motor cover is missing as it looks like most are and while an original would be nice, those offering them for sale are pretty proud of them, that, and I don’t really care if it’s missing. The serial number is 6-2382.

You sure about that serial? The records I have from VM indicate the following:
1941 13-0000 – 15-0000

I don’t have years prior to 41.

That looks exactly like my 1946 unisaw. Sure the serial didn’t fall off the backside of the table?

Get a Vega fence for it. You won’t regret it. Only upgrade I did to it. Might spring on a shark blade guard too, besides bearings

That’s why I think it’s made prior to 1941, it’s definitely the right number, I just double checked it.

Get an account at OWWM and start a uni thread. Upon second post you can add pics. Take one of the serial. Gents there know some unis.

I just might do that. In the mean time, in the off chance that someone on here is in the know about vintage Unisaws, here is the serial number plate from my saw:
