Dewalt stealthsonic to Pegas scrollsaw

[Misha]

Hi all

Ive been wrestling with how to move my scrolling indoors when the weather eventually turns cold and wet. Right now I’ve been pulling my saw out to the deck off of the workshop. All the equipment in there is on wheels and I use it outside.

ive started to do some marquetry and am enjoying it, I’m using a Pegas saw, and I’d like to hook it up to dust collection. I just purchased the 11 gallon stealthsonic because it has the same 2 1/2” hose as the Pegas lower dust collection. However, when you hook the dewalt up to the saw, the dewalt starts screaming because it’s starved for air, and the Pegas starts whistling through those tiny holes in the table.

Has anyone actually solved this problem? Many thanks!!

Sorry I have no ideas but would love to see some of your marquetry, RJ

Split the line to collect dust from the top also. That should do the trick! I use a full size dust collector with a 4” hose split into two 2” hoses hooked up to my Pegas.  You should be able to to the same with your vac. There are a lot of hoses and adapters available at many woodworking stores and online. Here is a picture of what i use.

Wow, thanks so much for the info. I’ll try to split the hose and run it up top. I ordered a scrollnado hoping it would do something similar, but I’m afraid that choking the dewalt down to such small hoses is going to choke the airflow and destroy the dewalt. It hasn’t arrived yet, and I’m not sure if it’ll work.
I like the way your system looks, may I ask where you picked up the yellow hose attachment up top?

I’ve looked at the Foredom madc20 that Seyco sells and that’s my next attempt if this doesn’t work.

Many thanks for the response!!

I've been using the 12 gallon Stealthsonic with the Scrollnado on a Bauer scroll saw. It's been an adventure. It came with 1/4" flexible tubing at the dust collection end. I found it unworkable and I'm now using the  3/4 black hose by the blade and a 1/4" nylon hose at the base. I found that the attachment strips didn't hold for long. I'm using strong magnets to hold the upper tube in place and a Rube Goldberg adaptation at the top of the table. I've taped an onion bag on the end of the 3/4" hose to keep small pieces from getting wedged in the tube. It's been a work in progress since I started. I had problems with the DeWalt Stealthsonic heating up, which may be the result of using small diameter tubes. DeWalt was no help. They had me file a warranty claim with Alton Industries and 10 business days later i got the entire top of the vacuum in the mail. Guess what? It heats up too. They didn't ask for the old one back so now I switch them out when one gets hot. 

DGMan's tubes look impressive and I've seen where others have successfully used pvc pipe. I found that the fittings for the bendable suction tubes on the market are threaded, so I don't know how the users got them to mesh with the pipes.

You would think some company would have solved this already. Just as an fyi the way I’m trying to step down the stealthsonic is by ordering 2 “Y” splitters with blast gates. The first Y will go on the stealthsonic hose, the second Y will go in one of the two connectors on the first Y, leaving me with 3 avenues to vacuum with. I’ll run one hose to the top of the saw, the other to the bottom, and the third one I’ll use the blast gates to partially open and balance the dewalt’s pull. I figure with the gate partially open on the empty connector, the dewalt won’t be starved for air, I can step down the suction on the bottom enough to stop the awful whistling, or just not use the Pegas connection at all and rig a hose like pictured above, and rig a hose at the top. By giving the Dewalt a chance to suck air as needed maybe the whole thing goes into balance. The Y Splitters were 28 bucks each on Amazon and if this works it’s a whole lot cheaper than spending 900 bucks or more on the foredom! Anyway, it’s comforting to know other folks are working at a solution here! Thanks for the info everyone!

Are you going to use the Scrollnado with the Stealthsonic? 

[Misha]

I’m going to try. I don’t want to hang 2 1/2” hoses on the saw, the scrollnado is at least sized for the saw. If I can use the scrollnado, split the hoses and connect one to the Pegas bottom dust collection, and relieve the restricted draw through the gate scheme, then it might just work. If not, I have an older Fein that has smaller hoses, and it might work, although it’ll be much noisier. Frankly Greg I feel like I’ve gone down a rabbit hole with this, spent too much money on it, and forgotten to actually make some sawdust! But I guess if this all works it’ll have been worth it…

Sorry, last question. Dan, you do a lot of scrollling, you’re running big hoses up top. When you’re flipping the upper arm up to make an inside cut, isn’t that getting a bit unwieldy? That’s a lot of hose to move up and down, not the weight, just the wiggling mass. Is it something you’ve just gotten used to?

The weight of the hose is minimal. I have no problem lifting the arm.
