Topic tags/keywords: jtas-10xl cabinet saw dust bottom

There’s quite a lot of space on the on the sloped bottom of the new (to me) cabinet saw. I’d like to seal that space up to keep dust from falling on the floor.

Here’s a photo:

My first thought was silicone (stays put, easy to remove) but those corner spaces look a little big (up to 1/4”) to hold a bead.

Second idea: foil tape, but those corners will be tricky to keep a crisp edge. I’m seeing something like the way our 7y/o wrapped his mom’s Xmas gift. Except I’m not 7 and this is my gift.

-- Yeah, I'm probably over-thinking it. But that's my other hobby.

White vinyl duct tape. Silicone caulk. Maybe even that spray foam that doesn’t
expand so much. That could be messy though.

I would probably use duct tape if there is room to apply it.
Doesn’t matter so much what it looks like. Only you will
know its there.

I used the foil tape, and didn’t worry too much about “crisp” corners. Like Ron said, this isn’t something someone will see. Mines been in there for over 4 years so far with no damage or problems.

Use a backer board or dowel and then add silicone.

I would use foil tape as much as possible. I like the spray foam for the tricky places, like to seal off the table top cavities and cabinet.

Excellent. Turns out I have some backer rod already just waiting to be used.

I got some backer rod from ACE hdwe one time. It was 1/4” and looked and worked like modeling clay. I can see that working well if the other doesn’t.

Thx Grandpa. I’m glad you mentioned it, as the stuff I have is more like 1/2.” I purchased it for renovation on the 1872 house we bought a little over a year ago. Anyway, it was too big for the purpose I needed it for -filling in a 1/4” gap -so if I can find the stuff you mentioned I’ll be killing two birds.

I think I’d use the puddy Gpa mentions or the silicone and then the foil back tape.

I have a large gab between my table saw cast iron top and the cabinet. I used Styrofoam to wedge in the gap and that really helped the HF Dust / Chip collector keep up with collecting the waste.

I have a few rolls of the foil tape and hadn’t thought about using that > Hmmmmm I’ll look at that tomorrow!! There’s also a few openings in the bottom of the cabinet I can use that for!!

Thanks and hope it works for you.
