Hey Guys,

Thought you might enjoy some of my pain tonight, After restoring my Unisaw, the last thing that I needed was a new base, you can see by the first pic that the base I got with my unisaw was cracked really bad. (part of the reason I got it so cheap. I went on owwm.org, and met someone online who had one spare one, and we agreed on a price, however, it took a grand total of 5 months to get it (customs held it up REALLY good) finally got it the other day, cleaned it, sprayed it, and now it’s time to install it. However, me being the lazy guy I am, I did not feel like dis-assembling the saw, the fence, the side table, the outfeed table, etc.. so.. here are some pics of how to change it the hard way!

First Pics, Here is the saw just resting on the old base (you can see the back crack, and the bad paint job the saw had before)

Here is the “Chair” I built around the top of the saw, the plan was to jack it up 1/2” and let the saw hang in the air while I change the base. I already jacked it up in the picture, and it’s sitting on the 1/2” spacers I made up.

And now, for a magic trick! how to make a Unisaw Hover!

Here’s the base before it gets bolted on!

And Finally, the finished project. I find that now that the saw is bolted on, it much more stable then just sitting on top of the post. (yeah, go figure) Finally, the Unisaw project is complete!!

For those of you who are wondering, this is what the saw looked like when I got it…. Saw was Built June of 1954, Still running with the original motor! Only thing I need now is the Goose-Egg cover…. but.. that can wait :)

i believe this deserves a big hearty “woooooooot!”

This is a really nice transformation. It looks better now than it did when it was new! I love seeing older tools, like this unisaw, refurbished and given a new lease on life.

Im guessing by the way you installed the plinth the sheet metal floor is MIA. For some unknown reason mine is missing also. You might want to get some pain on that dust door before it starts to rust. You can also get a nice replacement badge for it from Justin(naturalmystic) at owwm. He does great work and at $15 good price as well. Nice saw….just finished mine last week. What HP and is it single or 3ph?

I think the sheet metal floors were only made into the 40’s.. they stopped putting them in for some reason or another, I made us a wood floor that slips in, works better than nothing. The dust door is the only thing I have left to paint.. I lent my large compressor out, and just got it back, so I can finish cleaning up the back of it (which is still a little rusty) with my die grinder and a wire wheel. I still have the badge that goes on the front, once it’s done being painted, it’s good to go. It’s only a 1 HP 1Ph motor, but it is HEAVY!! runs great, I would like to get a 3 HP motor, but that’s another $600 I can wait to spend for now… Plus if I go to the 3 HP, I will have to murder the side of the case to make it fit and work properly, along with having to find a different dust cover for over the motor.. we’ll see, I don’t want to invest too much more in to this wonderful workhorse, I find that the 1 HP motor has more power than my 1.5HP Craftsman Contractor saw used to have.

Mine is 3ph and 2hp. There many 3hp motors out there that will fit without modifying the cabinet. I have found that 2hp is plenty, even ripping 8/4 walnut or maple. You might consider putting a want to buy on BOYD on the owwm site. You might be surprised what is available.
