I’ve wanted to upgrade my vacuum system for a while now and got around to it over the weekend. Thanks to my friend David Jones for his help with the pipes.

My shop is a garage more than a shop and everything has to be on wheels. I couldn’t run vacuum hoses across the floor so I had to run it along the ceiling. My vacuum system uses 4” irrigation pipe which connects to Rockler blast gates quite well.

The existing vacuum drop was a 4” fixed drop with a flex hose along the garage wall. For my new vacuum drop I tapped into the existing 4” line by adding a “T”, then ran a 4” pipe across the garage roof then down the length of the garage to my lathe, work bench area. By running the pipe across the roof I was able to keep the garage floor clear for vehicle parking. For stability a 4” x 10’ cedar post was installed between the garage floor and the ceiling. After the cedar post installation, I ran the 4” vacuum pipe down the cedar post to a blast gate. A flex hose was attached to the blast gate for use with my lathe, band saw, down draft sanding table and belt sander. All joints were wrapped with rubberized sealing tape. The new drop works great, this is going to be a great addition to the shop.

Good job!
Always gret to get help doing stuff!
Your garage looks as crowded as mine!
What are the black rings visible on the joints?

Robert, I’m on the anal side. I wrapped the white rubber sealing tape with a piece of black vinyl electrical tape to make sure the white tape did not come loose.

From another anal member (actually I now say I have a mild case of OCD), Nicely done!

If you ever have any suction issues at the new drop, you may want to consider replacing the “T” with a “Y” so the debris has a straighter shot back to the dust collector. A “T” places more restriction than a “Y” does on a system, which will reduce the static pressure, and therefore will lower the suction ability at that drop.

BUT, with all that said, you are much better off than you were! Plus, it came out looking really good, especially when a garage needs to be a garage (like so many of us deal with).

Looking good. Any chance of changing 90s to 2- 45s, gives you an easier flow on the turns. Nice job.

Nothing wrong with being anal,,, the only valve I know of at the moment that has the capabilities of being able to effectively pass gas, liquid and solid or nothing !!

Hmmmm, I would highly recommend wrapping the black electrical tape that is wrapped over the white sealing tape with some good old silver Duct tape just to be sure. :-P

Other than that it looks exactly like what I hope to set up in my garage one day. Good job.

Question; how loud is it? I live in a neighborhood with a horrible HOA, noise complaints are always a fear.

Have your say...
