home made over arm dust collection #1: Assembly instructions for my over arm dust collection.

Bear with me this is my first blog. I’ve had a few comments on my homemade over arm dust collection on my Ridgid tablesaw. First off I’ll tell you why I made it, I was just plain tired of being covered up with saw dust when I used the saw. Now I’ll tell you how I made it and give you some part #’s in case you want to make one for yourself.

Here’s parts you will need:
One T-connetor Rockler#88527
I had some 4” flex hose laying around, in case you don’t Rockler#22791
2’ of 1 1/4” hose came from a dead shop vac, sorry no #
4” to 2 1/4” reducer Rockler#23486
1 1/4” to 2 1/4” reducer Rockler#26967
7- 4” hose clamps Rockler#64528
1- 1 1/4” hose clamp sorry no #
3- 4” 90°Galvanized Elbow Lowes#36400
3- 4” x 24” Galvanized Pipe Lowes#36395
1- roll of metal straping

And now assembly:
I started with the 4” dust port on the saw, attach the uncrimped end of the 90° elbow to the dust port with a 4” hose clamp attach one of the 4’‘x24’’ pipes to the crimped end of the 90° with a 4’’ hose clamp rotate the elbow and pipe assembly so that it faces the right side of the saw. Add another 90° face it stright up attach with a 4” hose clamp cut a 8” peice of 4” flex hose and attach to the crimped end of the 90° attach the other end to the t-connector with a 4’’ hose clamp. Cut a 6” peice of 4” flex hose and attach to the top of the t-connector with a 4” hose clamp. Attach the other end the crimped end of a 4’‘x24” pipe with a 4” hose clamp. Attach the last 90° to the uncrimped end of the pipe. Attach the last peice of 4’‘x24’’ pipe with a 4’’ hose clamp. Insert the 4’’ to 2 1/4’’ reducer into the uncrimped end of the pipe and attach with a 4’’ hose clamp. Attach the 2 1/4’’ to 1 1/4’’ reducer to the other reducer with tape. And finnaly attach the 1 1/4’’ hose with a 1 1/4’’ hose clamp.
I attached the whole assembly to my saw’s tableboard with the metal straping, If you don’t have a table board you will have to find another way to attach it to your saw.
Now you will need to bore a 1 1/4’’ hole in your blade guard I used a 1 1/4’’ hole saw to do it. I put the hole in front of the blade on the guard. After the hole is compleated I cut half way through the the 1 1/4’’ hose and a length of about an 1 1/4’’. Then push the hose in to the guard and down until it touches the insert on the saw. Connect your dust collector to the t-connector and your done.

I hope that the instructions dosen’t confuse anyone too bad, I tryed to get my Photobucket account working to post some photos. Hopefully I will have them up in the next day or two.

Thanks for looking.
