Some of you may know that I've been working on the overhead dust pick up for my table saw. I have finished the second version today, and I'm having the same problem. I have tried the mount to the side (ceiling mount) and to the rear. But there is too much play side to side on the pick up housing. The wood doesn't want to slide under the pick up. Possibly my curve at the front is too abrupt, and needs to slant more to to ride up over the wood. But the whole housing moving side to side bothers me a lot. How stable are the commercial units that mount to the ceiling or the back right of the extension table? Any ideas on how to stabilize this set up?
The first picture shows the pick up, and hinging mechanism. I used the Wood Central Blade Guard article to go by. It is almost an exact copy...very minor changes in lengths beyond the pivot points, except for the extension from the attaching point to the dust shroud. This had to be lengthened because of where my TS has to sit in relation to the mounting point for the arm. (Lights directly above the TS) I'm sure this introduces some movement, but I'm surprised at how much I'm getting...3" either side of center, maybe a tad more. The second picture shows the mount at the ceiling that allows me to move the whole unit up and out of the way. It can also be taken out or pivoted in 90 degree increments to be further out of the way. Picture 3 shows the mechanism minus the dust pick up. Picture 4 shows the unit recessed as far as it will go up. (I'm limited by the shallow attic space or it could go all the way to the ceiling.)
The problem again is side to side movement as you are at the front of the TS. I hope someone has an idea. I'd hate to think about scraping 2 weekends worth of work, not to mention the steel and aluminum. THANKS!! Jim.
