I’ve been watching LJ for some time, and am impressed with the collective knowledge and experience here. I am a new member, as of yesterday.

This past summer, over exposure to Western Red Cedar dust led to me having been over sensitized, and I am now upgrading my dust collection. The last part that I haven’t finalized is table saw overhead collection. I’ve reviewed a lot of shop built solutions, both here and at SMC.

I can weld and fabricate, so a boom is no big issue, but the shroud itself will take a fair amount of time and fiddling to get it to the point of easy to use and remove when necessary, and still be durable. So I looked to just buying the shroud assembly from Grizzly (it appears to be a bit better unit than PSI). When checking the Grizzly website, it appears it isn’t available separately. I haven’t checked with Grizzly customer service directly yet. And I haven’t checked on the availability of the PSI shroud separately.

I need to make a decision and purchase soon, as my shop production begins to ramp up in March.

I would appreciate any input from anyone out there, particularly related to the PSI and Grizzly units.

My Grizzly G0623 came with a guard with a dust collection port. I quickly dumped that and got a Shark Guard.

Would you be able to create a shroud from some acrylic sheets? Lexan may be more wear resistant but I am not sure if its workability with regular tools. Welcome to Lumberjocks!

The Shark guard would be a great choice for you. The only downside is that normally Lee makes them to order so you may be facing a 6 week or so backlog. A shop built choice that is actually pretty good since you can fab the metal bracketry would be the “Badger Pond basket”. I built one of these as well, and didn’t use because I couldn;t come up with a suspension design I was happy with. It’s named (afaik) after a now defunct forum where it was first offered up by a member there. Here’s the url to the pdf file (I hope):

I don’t know how to link pdf files or I would’ve done that for you.

Mark, The only acrylic available locally is too thin (think storm window material). I would still need to design a suspension system, which leads me to want to purchase the pre-made shroud and suspension.

Fred, I’ve looked at the Shark Guard website: 4 month back log, so that isn’t going to work for me.

Thanks for the input.

Fred, thanks for that link. I had seen that unit before, and thought it would be perfect, but didn’t realize there was a set of plans available. I downloaded the plans, and will locate the necessary 3/8 Lexan, even if I have to order it.

I believe you have solved my dilemma, and I’m looking forward to building a nice piece of equipment for my shop and saving a couple hundred bucks to boot..

Thanks much!!

I ordered a shark guard back in October. Should be available hopefully any day! At the time he said the backlog was unusually long because of some supplier changes. So it might be better now then it was back then.

I was going to get a shark guard for my saw, however my saw is a 1980’s Jet CTAS and it could not be fitted with a riving knife. To me that was the main advantage to getting a shark guard in the first place. I came across a Excalibur guard on C L for $100 and bought that. In the end I have not used or seen the shark guard and it does seem to be the hottest guard right now, however I am very happy with the Excalibur as it easily moves out of the way when necessary and can be left in place for non through cuts. I riving knife is desired, but there are other means to reduce kickback.

Bill, thanks for posting that pic. I am planning on a similar design for the support boom, although I won’t run the air through it, as I am not sure I could get two sizes of lightweight tubing that slide together, and find a seal for the sliding joint

I’m presently looking at telescoping square tubing for the horizontal member, telescoping round tubing for the vertical adjustment at the blade end, and larger diameter pipe at the support end, to allow swinging it out of the way or completely removing it.

$100 for that unit is a helluva deal!!

Yes it was a great deal. I have looked on CL for years (Indy area) and have never seen one. Driving up I figured this was a used hard system and would offer him $80. When I saw it I just handed over the full price quickly and put it in my truck. FYI the vertical (black square piece) that sits on the floor has two steel straps that attach to underneath the table for support. This gives the whole system stability. I can take pictures if you need.

Bill, thanks for that offer. I think I’ve got my basic set up figured out. Just trying to figure my materials. I want to keep the guard end as light as possible, and will use some aluminum (which I can’t weld). I’ve got a pretty good supply of steel for the support end and can build that plenty rigid.

I want to have some telescoping ability in the boom, and will probably go with square steel tubing. I’ve used that for solar electric panel supports and have it worked out pretty well.

My UniSaw has the cast iron grid extension table, so I have plenty to anchor to.

Just an update. As mentioned previously, I’ve committed to building the Badger Pond/Sampson unit. I went through my collection of steel tubing to find what I could for the support arm. I have some pretty heavy stuff for the vertical support from the floor.

I had to buy some square tubing in the sizes I needed for the horizontal portion, and I ordered 3/8” polycarbonate on line. The polycarbonate was just shy of $50, delivered, but that is the most expensive individual part of this project. Also ordered some miscellaneous small hardware, after not finding it at my local suppliers.

I’m working on this between other projects, so it will be a few weeks in the making. I just finished the dust shroud. I thought about gluing it together, or a combination of gluing and screwing. But after reading about the hazards of methylene chloride (I think that is what is used), I decided to just screw it (ha ha).

Many 6-32 holes to drill and tap, all but three of them blind holes. Had a few holes not come out perfect, but overall, it’s OK.

Here’s the shroud, temporarily assembled.

Here it is,, ready for the dust collection fitting, which is a 3” hole in the shroud, stepped up to a 4” flex hose.

This is my first time posting pics here, so I think I’ll stop here and see if this is working right.

here’s a ghetto version made from the OEM blade guard adn scraps from around the shop. works quite well:

the overhead arrangement means it can service both of my table saws.

My ductwork runs under the floor, and my ceilings are very high, thus the need for a boom arm. The plan is to have it swivel at least 90 degrees, both to get it out of the way when necessary, and reach a second saw which is in the reverse direction, outfeeding on to the right extension of the main saw.

The plastic work is probably the hardest part of this project. I can do a reasonable job at metal fabrication, and enjoy it, too. The polycarbonate was a pain in the butt.

Last summer I purchased a Grizzly G0691 TS, and bought the Griz T10113 overarm DC as well. It is available separately for $295. See it here After about six months of usage, I am very pleased with it. It catches most everything that doesn’t go down into the cabinet, is pretty easy to set up, and easy to swing out of the way if you need to change blades. As a bonus, it adds a layer of protection between my fingers and the saw blade. So far I would give it two thumbs up. Hope this is helpful.
