I’ve got a 1950 Unisaw that I’m trying to figure out the best place to cut out hole for the dust port on.

The 5” dust hose will be coming in from the motor side. I’ve already cut the cabinet for the larger Baldor motor, so I’m not sure if I want to take away any more material on that side.

I leaning towards the bottom of the outfeed side. And, I was going to put it off to one side so that I don’t have to cut through the center seem – thinking that it will help keep some strength.

I guess my question is, is there a ‘best place’ to put the dust port?

With those old cabinet saws, you will have to build sloped sides into the bottom part of the compartment
to get the sawdust to feed to opening, and even then sawdust collection is not real good. One person
here on LJ, can not remember the name just hooked his 2-1/2” hose directly to the bottom of the U shaped
chute in front of the saw blade with good results, and I am thinking of doing the same thing since the chute
and hose opening I put in the access door in the front is not working real good.

I just hooked a big shop vac to a hole in the back of the plinth like Toolie did, but with 2-1/2” hose. I can honestly say that it works pretty badly. One reason is what Bluepine alluded to – these older saws weren’t designed for efficient dust collection. Another reason is that I have no motor cover on my saw (yet).

Since my Uni also tends to spit a lot of sawdust forward over the top of the blade, I’m piecing together an overhead blade guard with a dust collection hose. We’ll see how that works.

Its sacrilege to cut one of the cabinets on an old unisaw. You will go to hell.

Another reason is that I have no motor cover on my saw (yet).

a motor cover, louvered dust clean out door on the front of the saw and the floor i fabricated for the bottom of the saw base worked together to positively impact dust collection. dust collection was good, especially when i added the missing motor fan to the bell end of the motor. with the fabricated motor cover, there was enough air circulation within the cabinet to keep a good deal of dust suspended while the 4” DC drew air across the floor from the motor clean out door.
