My two step sons work for a company which install encrypted audio-video systems nationwide, They install these systems in government offices , in courts, churches , LDS temples and stakes, schools and so on.
This company needs a lot of wooden boxes, speaker enclosures and so on to install their products.
This company used to to have another company in Wyoming to make all these boxes for them. It took several weeks to have the boxes ordered, made and then shipped to SLC Utah.
About two years ago, one of my step son, who was then the project manager, needed some boxes made over-night. I asked me if I could make them.
I made the boxes.
Since then I make all the boxes, speaker enclosures, pulpits and other stuff for this company.
The money is really good, I average between $40.00 to 60.00/hour, which for a side job is not too bad.

Last week then needed some plate made to install new speakers in existing speaker enclosures.
The plates had to be 16”x16” with a 10” hole in the center.
At first I had no idea how to cleanly cut 10” holes.
I found on YouTube a video which really helped me a lot.
I needed a circle cutter jig to use with me router to cut the holes.
Instead of buying one, I made one.
It works perfect.

Thank you for watching

Looks great. I made one last week for my bandsaw. Very simple but works great as well. Nice job!

nice looking jig. What did you use to adhere the HDMSKA (slick plastic) to the upper base?

I found your circle jig when searching for examples online, thought it was quite clever, and build one very much like yours. Instead of using two “base” pieces, I only used one though, and routed a slot into it for an aluminum piece. My opening for the router is also wider, I am hoping to catch more of the dust this way. I am thinking of beveling it as well.

One thing I always wondered about: Why are most of these (including yours) tapered towards one end? Is there a practical reason for this?

Thanks for the inspiration!

Nice jig, and thanks for sharing the story behind it. Sounds like your step-stons have a pretty neat job!
