Well I’ve been looking to upgrade my current jobsite table saw and so I picked up a junior Unisaw., circa 1950. I couldn’t pass up this charming little machine, so I kind of just went for it. If it is the original motor (I haven’t torn into it much yet) than I believe it is either a 3/4 or 1hp motor? Regardless it sounds beastly but seems to be running smooth for a saw this old. Everything is in fair shape and I think it should serve me well for a while.

I have not found any information so far, but was wondering if indeed an aftermarket splitter or riving knife can be purchased for this saw. I know it didn’t see many years of production so I am assuming it probably won’t, but I know this is the place to inquire further about that.

Any other info would be greatly appreciated about what I just got myself into… ;)

PS, I’ll post pictures soon, but don’t have any available yet.

Yes, please, pictures! Really curious about it. If it’s a Junior Unisaw, perhaps there’s a chance that the dimensions of the relevant parts for mounting aftermarket splitter or guard are the same as the standard Unisaws.

Also, you could check the vintage machine forums—owwm is one. Perhaps Google “vintage woodworking forum” and see what pops up. Those folk are usually dedicated and pretty friendly.

Congrats and I agree with ForestGrl, look around for a manual and other information

Thank you both for the replies. Good point forestgirl, I’ll have to look into that. Looks like the motor is original. Overall its a bit more rough than the picture shows in regards to the cabinet including some ‘aftermarket’ holes etc the original owner created but generally is in pretty good shape. So far I’ve just cleaned it out, blew out a lot of the saw dust, oiled the moving parts and treated the cast top a bit.

Attached is a photo of a part that I believe held the original blade guard (which it did not come with), I’m wondering if that could be an attachment point for a aftermarket splitter.

And lastly, the only damage I’ve seen that may need to be addressed soon is a cracked arbor washer. Im assuming/wondering if this is a generic part I can just order that doesn’t neccesarily need to come from this saw specifically but only needs to fit the 5/8 arbor?

Thanks for reading, any thoughts suggestions are appreciated.

The generic model number for that saw is 34-260… add extension wings and the guard and it becomes a 34-265 which is what yours looks like. AFAIK, the only parts it shares in common with the Unisaw is the hand wheels and pinion gears for the raise/tilt mechanisms. Everything else I believe is specific to that machine except for the obvious hardware store items. The arbor flange washer should be generic as well.

Stewbot, if you post the measurements of the square part where the splitter connected, and the width and length of the throat, we can compare it to Unisaw (of which I have 1). You can always make a splitter for a shop-made throat insert (a rod or a flat one). Pair that with an overhead blade guard (such as a PSI) and you have protection and dust collection, but it’s still easily moved out of the way for non-through cuts.

Thanks for the link forestgirl. Measurements of the part pictured: 1 7/16” wide 2” tall. Throat is: 10 15/16” x 3 9/16”. I’m gonna email that company I’ve heard about that makes aftermarket splitters etc. and see if they’ve got something that might fit, if not something compatible with a more popular unisaw. I’ve never seen a homemade splitter, I look into that. In the mean time I’ve just been trying to dial everything else in.

Thanks again for the suggestions.

I have this saw, but it’s not all original. I have added (2) 9” x 24” extension wings and longer fence rails, + a safety paddle switch. I used a vintage Craftsman 1HP motor. A local rewind shop wanted too much to rebuild the original Dayton motor.

I never new that Delta made this model. Looked it up, and I see it’s an 8 inch. I also see it has the Jetlock fence, which I had on my old Rockwell contractor’s saw. I hated that fence from day one (and any fence that “relies” on clamping on both ends of the fence. I’ve never seen one that doesn’t move when bumped, and requires measuring, from both front and back teeth, to make it parallel to the blade.

I discarded mine, and made a T square type fence, which worked pretty well for the remaining years I had it.

Check with Leeway workshops (aka Shark Guard) to see if he would have a splitter for it. He has a new adjustable splitter that follows the blade up and down (manually adjusted, however), functioning almost like a true riving knife.

Of course it wouldn’t be hard to make your own.

Nice looking Unisaw Jr. Mine was a mess when I bought it. I had to restore it. I have it all done except the motor is full of saw dust. I am interested in a splitter info also.

Have your say...
