James Roadman Instrument Repair
I had these DeArmond Hershey Bar pickups come into the shop for rewinding recently. These pose a couple of challenges – the covers are riveted to the pickup and the coil is wound around the magnet which is unsupported on top.
I am sure the proper rivets are commercially available but I wasn’t able to figure out where to get the proper ones. The world of rivets is more varied than one might expect. Considering how often I do this repair it was just easier to make them. I had some 3/16 nickel rod on hand it is not too difficult to machine them on the lathe.
To wind the coils I made a temporary support that was bolted onto the bobbin with cellophane tape in between. I was able to wax pot the coil to make it more solid before removing the support.
