My project was inspired by another Instructable: https://www.instructables.com/id/HOWTO-Compression-Connectors/.
Step 1: Supplies & Tools
3/4 inch hardwood
Washer (Metal or Plastic)
J-B Weld (super strong two-part epoxy)
Drill (not shown)
Hole-saw blade (1 3/4", to fit the body of the caulking gun)
Drill bits (1/4", 3/8" & 5/16")
Bench vise (not shown, to hold disc & washer while cutting slots)
In the picture:
Top row - Hole saw blade, drill bits (1/4", 5/16", 3/8"), metal file, rat-tail file, metal saw, coping saw
Bottom left - J B Weld
Step 2: Cutting the Holder and Pusher
I then sanded down both pieces.
Step 3: Making the Holder
The second picture shows a dual coupler with wallplate I got at a dollar store.
Step 4: Making the Pusher
After the first use I noticed that the blue collar was leaving a mark in the wood so I added a metal washer. I cut a slot in it to match the wood, cleaned up with a metal file. Held on with J-B Weld too.
Step 5: Using the Homemade Wooden Coax Compression Fitting Tool
1) Cut Coax wire with Flush Cutters
2) Strip the Coax wire
3) Slip the Compression fitting on the wire
4) Screw the fitting onto the Holder (coupler, Picture #1)
5) Slip the Pusher on the wire up to the end of the fitting (Picture #2)
6) Put the whole assembly into a Caulking Gun (Picture #3)
7) Squeeze the Caulking Gun handle until the fitting is fully 'compressed'
8) Admire the fitting (Picture #4)
