Charly-In-Ct-Ri inFebruary posted a brilliant repair for broken mouse ears. A;l credit goes to him. I just tweaked his ideas.
No matter how careful I am kneeling and standing I somehow managed to break a half dozen expensive coils. I tried repairing them with nylon washers and even glueing them on before using them.
They still broke.
So I was enthusiastic in trying his repairs. But they centered around plastic electrical boxes that he cut and reshaped using PVC glue and primer. But I could never find the right size. They were always too large.
Well one day I was wandering through Home Depot and found myself on the PVC aisle and saw some joints and connectors that looked like they might work. So I bought several sizes and headed to my garage.
First I selected a coil and with my Drexel I started carefully slicing away the broken ears. Then I took my sander and smoothed it off. I then selected the right size cap and placed it on the coil and it looked like there was adequate surface area to support it.
Next I measured where to drill the holes and after using 4 different sized drill bits I had the right holes. But after connecting everything I realized there was still too much play. So I began adding nylon washers until I had a good combination for a snug fit.
I wanted to be able to have a little vertical play with the shaft so I took the Drexel and cut a space in the cap at the back. A little use of the sander smoothed up the edges. Then I also sanded the bottom of the connector to rough up the surface so the PVC glues will hold better.
Then I painted it. Mostly to hide my poor craftmanship.
I first used PVC Primer and then PVC glue to attach the 2 pieces. Always add the adhesives on both pieces. I let it sit overnight.
The next morning I tried to break the bond but it seems strong.
It’s a bit of a challenge to hook up the bolt, coil and washers because it’s a tight fit but perseverance will make it happen. A foam sealant might help if there’s too much play but this seems to be what I need.
I took my Garrett ATPro with the patched 5x8 coil out yesterday and today. I was cautious at first but before long I forgot I was using a broken coil. No problems and I even found a few things.
