Well this was my second project over the summer.
It took about 2 weeks to do, and i learned a lot. If i had to sell it, it would be like over $2000.
When i was done there was 249 rivets, ya 249. So in the viewing window i added one extra rivet just to round it out to 250.
It works with an old vacuum i had and its ok.
I sealed up every thing with foil tape, on the duct and the rest of the saw. Pictures
1. The viewing port, front of saw. You can see the extra support i built for the shelf above the duct.
2. Another front view, showing the piping. (also the switch for the vacuum, haven’t made a full install of it)
3. Full view of the front of the saw.
4. Before the full install, user view. Ya rust on the saw is gone now, fully gone, now its beautifully waxed, a week later i bought some boeshield t9 for something else and wish i had used it on the saw.
5. Opening of the viewing port. Everything lines up perfect and the miters to the front of the duct are spot on, to bad you can’t see them with the window on.
6. Rivet #250 Baby.

Here is the full set of pictures i wanted to share
Backside of duct, back of saw

Picture of the tubing, i should have shown it with the vacuum, although its not the prettiest thing.

Backside of duct before the initial install, eww rust.

Underside of the duct

Inside view, upside down (before i did the taping on the inside)

This is a pic from inside of the saw looking out after the second taping job i did to help with the flow of saw dust, with the viewing port on the right and the exit in the center. i really need a dust collector and get some 4in ducting going. but really i want to just make a shroud around the blade and it would be way more efficient.

Out side view of the viewing window, without the wing nuts

Here is the viewing window with seal, and #250

And again, #250

Well there it is. This was one of the first items i built this summer. It came after making these 3 dollies for my jointer, router table, and this shelf unit. I wanted to do more and this was the first project that came up after finishing those. I got sick of picking up the saw dust real quick. after that, big changes. my garage went from storage to a woodworking shop.
The duct is pretty much the most anally built thing i have ever made. I have made one other thing with sheet metal and rivets. It was for my car, and guess what, it was radiator ducting. The duct for the saw doesn’t work right now to its full potential because of the crummy vacuum connected to it. But i think when i get a dust collector it will work much better. Even with the vacuum not really sucking all of the dust out, it keeps it all contained and im happy with it.
And to leave you with some pics of my garage now. All built by me, except the work bench. Everything pretty much on the table saw was replaced as well (side top and shelf).

Rivet overkill :) Do you have any left now?

Looks like you have a nice set up now. Let’s just hope the saw doesn’t ever break down. ;-)

Nice job, but that looks like a TON of work.

I think you to talk to a therapist about all the rivets…...You need help….but it looks great, and should last forvever.

I would have limited the rivets as well – just enough to maintain the structure shape. Lots of drag from the rivets sticking out inside. It wouldn’t be pretty, but if you reversed the rivets it would have less air drag and more room for air movement. Reversing the rivets and using metalized ducting tape on the inside would have done the deed.

Nice idea though. I need to do something like this as well. Thanks for the idea.

Very rivetting project. (Sorry, I couldn’t stop myself)! Having assembled just a few metal cabinets held together with rivets, if you did those with a manual rivet tool, I bet you have a serious grip in a hand shake now. I saw something very similar recently available commercially, except the joints were spot welded instead of rivets. It looks very well thought out and it certainly is not going to fall apart. However, I do think the rivets may lead to some air restriction. I would think that you could have used fewer rivets, or even short sheet metal screws, but use some sort of adhesive. Very likely a common construction adhesive would work or possibly a silicone based adhesive. Then as has already been mentioned, apply some foil seam tape to smooth the inside.

Cool pics.

Great shop.

NICE design.

MY first reaction to this concept was …. to think how much I miss my old Airstream.

For we who had Airstreams …. grew to love the pop rivet, with time :-)

By the way … shop safety DOES indicate that we should NOT wear loose fitting clothing, while woodworking, but … isn’t a 3.5mm neoprene suit just the tiniest bit of overkill ? ;-)

Thanks for sharing. Looks a little Mad Max, to me. I dig it !

Well, cool concept, but your probably finding out that your not pulling in near enough cfm with that little pvc pipe. I’m guessing even with a huge dust collector hooked up to that your only pulling 150 to 200 cfm max.

well if i got a dc i would be replacing the tubing indefinitely. at the white part of the tubing there are threads that are about 3 1/2 in, so it would be making something to fit that

just to let you guys know, ive been using my saw a lot lately and its been really nice having the window there to help clean it out. i wouldn’t have to clean it out as much if i just got a dust collector but im really saving up for a bandsaw.

.... well that was… Riveting! lol. nice story about your dad – I “helped” my dad build a boat once, I think know your feelings about having tools taken out of your hand.
I agree with your best friend – You have a shop now.
