Dust collection solution for my Unisaw

My new Unisaws’ dust chute just dumps on the floor..can’t have that! I tried to track down the Delta made dust collection adapter , but since this saw is 8 years old I couldn’t find one anywhere, so I figured it would be easy enough to make one. Here it is, in all its simple get ‘er done fashion!

Just a 4” universal dust fitting from Woodcraft, and some leftover 1/4” ply. I made sure the bottom of the outlet flange was even with the end of the dust chute to try and get the sawdust out as efficiently as I can. I was thinking I might go around all the seams with some foil back tape I have leftover from sealing up the seams on all my duct work in my house.

I managed to track down that dust chute part for my Unisaw a few years back (don’t even remember where I found it). However, I like yours just as well, if not better.

Should work great. What about a sloped piece inside the cabinet so it feeds the sawdust towards the shoot. That would make it similar to the new saw and not much stays in the cabinet. Just a thought Dave

Actually, Delta had that idea already! The bottom of the cabinet is a slanted dust chute. I aligned the bottom edge of the dust port with the bottom edge of the dust chute, so the chute should funnel the dust right to the opening. I haven’t really given it a workout..I cut a few pieces of scrap to test it out but it seems to work good so far! I can feel air being sucked down through the insert..which reminds me..I have to make some zero clearance inserts!

BN: Shoot looks good—that’ll work. Next, do like you talked about and tape up every crack and crevice in and around the top and any other holes you find with the foil tape. If you don’t, you’ll see dust escaping, and it’ll be on the floor all around the saw. I taped every crack and hole I could find when I got my saw with that tape.
Stopped that nonsense. No more dust all over the saw sides and on the floor. Works for me-should for you.
Have a good gobbler day, and keep on keeping on.

I know this was posted a while ago but I just stumbled across it today looking for some info. I am currently planning to retrofit my Rockwell unisaw with the new dust collection system off the latest model unisaw.

You can find all the parts and instruction manuals for most delta models on their service site.

I purchased the major parts for just under $22. I know that’s a little more than the fix listed above but it works well for what I am doing.
A27746 BAFFLE $6.50
A27748 HOUSING $8.00
A24283 ADAPTER $6.96

Have your say...
