I have been wanting over table dust collection on my saw for years and have jury rigged some systems at times but with all the other upgrades to my shop in the last while I felt it was time to get a little more serious. I did some research on the internets and found this thread:

www.woodworkingtalk.com/f2/shop-built-table-saw-overarm-dust-collection-hood-45394/

I didn’t have an biesmeyer overarm system like in the thread but I have low ceilings! Made completely from scraps (birch ply, spf 2×4, birch and acrylic), it can be locked up using the black knob on the right and is positionable up/down/left/right (pic 5) and is easily removed with two knobs.

My only major change to the hood is the acrylic ramp at the front which allows the hood to ride up over the fence on my crosscut sled.

I am running a $30.00 mastercraft shop vac in to it at the moment and it does and awesome job!

Thanks for looking.

Nice job! I’m gathering parts to get ready to build my own customized overarm collector as well. That bungee cord acting as the counterweight is an interesting idea which also helps with the footprint. I might use that to some degree.

Glad you found some inspiration in my design and yours looks great as does your sled!

I went a little different route with my new sled that allows use with the hood in place http://lumberjocks.com/projects/149410 and I am actually in the process of making some modifications to my hood again that I will be posting here as soon as I get time to finish (I think I am going to add your ramp design for use with other table saw fixtures I have!)

Thanks Marv… I have been sitting with that tab open for about two weeks waiting to do this.

You’re welcome and I’m flattered that you chose to use my design for inspiration!

For anyone that is thinking of making one some quick tips. Don’t oversize the bolt holes on the parallelogram, I did on my first iteration and it allowed the hood unit to rack which interfered with the smooth operation of the hood mechanism while rising. Also I didn’t balance the hood on the arm that supports it, while it is ok on mine I feel that the hood would work better if balanced or slightly weighted towards the back (mine is slightly front heavy and I can’t move the arm any more because if the vacumn hole.

Good points Lumberpunk. On my new one I am using nylon shoulder washers since my current one has worn holes and racks as you mention.

Sweet! I hadn’t made one because all the plans I saw needed to use up footage on the floor of my workshop. Love the idea of the upper part of the jig being attached to the ceiling. The adjustments on the lower part of the arm both north and south and east to west makes this the jig I’ll base mine on.. Can’t wait to get back in the shop again.

I too used Marv’s design for guidance, I made mine from scraps around the shop. I used a gutter downspout fitting to attach a 4” hose and tied it back to my 2.5 hp. tempest DC

It is very rigid and does a great job of collecting the dust until the blade gets to the end of the board, then it spits out a small amount of dust.

Looks like your design with the front angled back may catch some of that end of board spray.
