Intro: Homemade Wooden Coax Compression Fitting Tool
Here is my Homemade Wooden Coax Compression Fitting Tool. I needed a Compression Fitting Tool to make my own cables but I did not want to pay $10-35 and I wanted to see if I could make my own. This tool is inexpensive and portable.
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 put a 1 3/4" hole-saw blade in my drill and cut two discs from 3/4" hardwood; plywood or particle board would be OK too. If you don't have a hole-saw blade you can cut little octagons (stop signs).
I then sanded down both pieces.
Step 3: Making the Holder
For the Holder (left in the picture) I expanded the initial hole with a 3/8" drill bit and a rat-tail file until I could fit a Coax coupler snugly (or you can hammer it in). I secured it with some J-B Weld.
The second picture shows a dual coupler with wallplate I got at a dollar store.
Step 4: Making the Pusher
For the Pusher (right in the picture) I expanded the initial hole with a 1/4" drill bit and the rat-tail file, then I cut a slot with a coping saw and used a wood file to clear the path until a Coax cable could slide in snugly.
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)
