Topic tags/keywords: unisaw 1947

I just bought this Unisaw saw and I want to put it on a mobile base. It is really heavy as the top has left and right wings added to it. The top is off of it now. I want to locate it ONE time but keep it on a mobile base just in case.
It has a cast iron base.

What type of mobile base would you advise me to put it on?
I will be posting pictures and have other questions but for now I need to locate the saw to its new spot.
I have it on a 2×4 framed cart that puts it about 5” off the floor so I want to get it from there to a lower cart
and stronger casters. I’m excited about this because I never thought I would get to own one of these.

Advice needed. larry

I built my own for a much heavier PM planer. Just screwed and glued some oak. Bought casters off … McMaster carr maybe. It works fine. Held up for 8? year with no issues. No reason to spend a lot of money one. WE are woodworkers after all.

Welcome to the Unisaw club ;)

The cast iron plinth is a bonus, but unfortunately, AFAIK, it prevents you from using the stock Delta Unisaw mobile base (cat #50-273), which I like because it’s all welded instead of bolted together. But there are plenty of suitable aftermarket ones, by HTC and others, and I’m sure someone with the same setup will chime in on what is what. I originally made one for mine out of bed frame angle iron, but wound up re-purposing that and getting the Delta base instead.

BTW: You can date the machine via the serial number

Cheers,
Brad

Thanks Jeff, looks great.

Brad, where might I find the serial number? The motor has been replaced with a new 2hp Leeson. I gave
I gave $150 for the saw and figured the motor had to be worth that. I have two Unifences, a 30 and a 50 both in excellent condition so I don’t need the fence that came with it. Over the years there has been some mods done to it but I want a saw for work, not art. Pictures and further advice will come once I get it set in place and 220v run to it. Any guess as to what it weighs? It is all I can do to pickup the table for about 1/2 a second. I need a heavy build.

Follow the link for serial numbers I gave you before. It will show you what the different serial number badges looked like. They were typically located on the back or side of the machine cabinet, however I believe some have been found on the edge of the table. Very early ones had them stamped in the angle dial bezel.

As for weight… catalog lists it at just over 330 pounds with everything (extension wings, stock fence, miter gauge, etc…) except for the motor.

Cheers,
Brad

Brad, I have looked and looked but I will keep on as it has dodged me so far. Is there a place to get a copy of a manual as I know nothing about them and that would really help. larry

I have a 1951 Unisaw, and when researching it to pick it up last year, I came up with a weight of 385 lbs. I believe that included the motor, and mine has the R/I bullet motor, which alone is 85 lbs. BTW, I love the saw. Good luck. Jim

I have a number of my machines up on casters including an 800 pound Hammer sliding table saw. I find I don’t need locking casters. The weight of the machines keep them from moving with use. I get my casters from Harbor Freight and find them to be very good casters and a lot cheaper. As to the machine height, I ind I quickly adapt to somewhat higher table heights

Larry, go over to the vintagemachinery site and you will find all sorts of info about your saw – pictures, manuals, catalogs and other stuff. There are several ‘manuals’ for the Unisaw over there, and given that the Unisaw remained virtually unchanged since it was introduced in the late 30’s, most all of them will be helpful. Of course, one dated around the same time as your machine would probably be best ;)

For Delta specific stuff at the VM site, click here.

Cheers,
Brad

Sorry for the late reply guys I was working late trying to get that saw off of one cart onto another. Finally done!!!

Planeman40: I was hoping that was the case. I had a very low heavy duty cart handy so I did set it on that cart and it works fine. It does anchor itself so for the time I will settle for that.

Bondo: That looks like a really nice base. If what I’m using doesn’t workout I will certainly give that due thought. Thanks for the link.

Brad: I will do that very thing. Thanks for the links it really helps.
I appreciate all that you guys have done for me, it is very encouraging as well as helpful.

To All: I will post pictures as soon as I can of the saw and what I got for $150.
If I can get the fences out of the dark corner of my one car garage shop I will include those photos also. Till then, a bazilion thanks for being there. larry

Welcome to the Unisaw club!

+1 Vintage Machinery for product information.
Another good source on Unisaw rebuilding is OWWM.org forums.

+1 Shop Fox HD mobile base.
SF recently upgraded the wheels from plastic core caster, to steel core; which is good improvement. I like the flip down stop on the Grizzly Bear Crawl mobile base better than SF. Bear crawl has slightly more ground clearance if you that is important.

IMHO – Before you decide on mobile base, sort of need to decide on fence length?
With short fence, can use mobile base under saw cabinet only.
With longer 52 in fence, there can be lot of weight hanging off one end of saw. While it is hard, it is not impossible to stack 80lb planer plus some wood on unsupported end of TS table and tip saw over. DAMHIK.
So with long fence, really need a mobile base with extension to support legs under far end.

Have used a lot of different mobile bases. Wasn’t happy with retail options, so I made my own mobile base.

Captain: Quite interesting but you are way above my working skills. If i get past this last kitchen build my major work will be done and then I can do the fun stuff. Keep the faith and you will solve all the problems that you encounter. How happy you are going to be when it is all finshed and working. :)
Thanks for your advice. larry
