So - a fellow from Lumberjocks.com asked me how i did the dust collection on my Wadkin AGS. So i made a short video for him. Since it took me a while to figure it out, i thought i might share it here as well, since others might be in the same situation.

Misterfish was kind enough to help me out by sending me pictures of his original Wadkin setup, so i took it from there, and made this:

Since i made the video, i actually bought one of those magnetic signs you see on student driver cars, that i cut in half, and put a notch in, to fit over the hole where the tilt handle moves. It actually says "student driver" (in Swedish though), which i think is kind of cool.

I also ut some foam rubber in the slot under the table

So - now most of the air is sucked down throught the throat, so boring a couple of ekstra holes in your (home made zero clearance) insert will help getting more airflow where you want it.

Looks a good solution Peter,
I know you say you don`t run the saw for more than 2 minutes at a time, but I think i would still want some ventilation to the back of the motor, could you not fix some flexible ducting to the fan housing & then route it out of the box, this would ventilate the motor & still allow the motor to move.

I`ve recently converted an old Wadkin spindle from 3 phase to single & while I was at it I`ve tried to improve the dust collection, I found spray foam really useful for sealing the ribbed section of the underside of the table to the main body of the machine.

Yes - in my case i does.
The bigger the gap around the blade at the throat plate, the more difference it makes.

A table saw cuts the wood with the teeth of the blades going down into the cabinet, so what i wanted was for the largest amount of air to pass by the blade under the table, to help the teeth get rid of the saw dust. If there is a lot of gaps in areas further down in the cabinet, that air is just "lost".

Being a HPLV system, you can't plug up all the holes, since you will starve the DC of air, but if the hole around the trunion and in the throat plate is left, that's plenty.

I plan on making an over head dust thingy, so i will lose some air volume there too.

Anyway - there is no sawdust by the base of my saw. You can kind of see in the video, that the area around the saw is pretty clean.

The reason i mounted the box over the motor with those quick release thingys instead of a hinge in one side, is because i want to build a cabinet on the mobile base, and a swinging box would require more space to open.

Space is at a premium, when having a 34m2 shop :).

Doug B:
I thought about it, but the HVLP moves 2000m3 of air an hour, thats 500 liters of air a second, so as long as i turn the dust collection on when using the saw, the motor will get more "fresh air" than if it was "free", with no dust collection. And as stated - the temperature didn't rise in the cabinet at all when running the saw for 10 minutes, 5 of those under load.
Now - if i ran the saw without the DC, and the box closed, i would agree, that it would be bad for the motor.
The foam i cool, but i was affraid, that if i wanted to adjust the tables mitre slots to the blade some time in the future, it would be to hard to move. I will use it for my old planer (jointer).

I've not had any temperature problemss with my saw when running for longer periods - though I do always use the dust extractor. What I must do is experiment with blocking up some of the many aperures to force more suckage down from the blade area, and then maybe also extract from the blade guard.

I stumbled across this forum and this thread from a google search. I thought I might show what I have done for dust collection on my Wadkin Bursgreen AGS 12 table saw. It works really well as you can see from my demonstration video here. (well, I apparently cannot post links either).

My idea was to catch the dust right at the source. Catch the dust straight tangentially below the blade and cut off the airstream from the blade. In order to be able to tilt the saw to 45 degrees I couldnt fit the chute around the entire blade, but just in the front.

I tried to post images but it seems I am not allowed to do that. Not allowed to post images, link to anything so this post seems kind of pointless. What do I have to do to post anything?

Hi Vetrex and welcome to this forum. You will be able to post links after some more posts (it's an anti spam thing). I found your you tube video and your dust collections works very well. I am very interested in this as I am about to do something about under table collection on my AGS10. I have recently stopped using the saw in favour of my TS75 in a CMS unit until I do something about the dust, the CMS works OK but I am dying to get back into using a real saw. Any more details about how you built the duct and attached it under the table would be greatly appreciated.

Well, there is not much more too it than what you see in those pictures. I dont have any measurements or drawings of the chute since I just designed it on the go. Here are a few more details as I remember them.

The transparent plastic is 1,5mm polycarbonate and the white painted stuff is 12mm birch plywood glued in 3 layers to become 36mm thick.
The whole thing is mounted in the holes already in the saw, for the original dust-deflector plate. It is as tight as possible with minimal gaps up towards the throat plate, it does not move up and down with the saw blade but it is still very efficient both with 10" and 12" blades at all heights.

The greenish plastic piece is 3D printed and I have a Fusion360 model of that. It is a very tight fit when the saw is tilted to 45 degrees, hence the odd shape.

Shame your not making a batch up to sell Vectrex, I am sure they would be a few people interested, myself included.
