Another trivial lathe job…
My ’86 Vanagon fuse box has multi-prong connectors in back. Some are spade, but most are the round prong variety, very similar to “Molex” brand. The individual metal connectors insert into the plastic blocks and are held in by “barbs” on the connector shaft. You can’t pull the connectors out of the block without damaging those barbs unless you have the special tool.
I made a couple of the tools for each size of connector. I used a large nail (spike) for stock and I have to admit to not really having confidence that the idea would work, so the you have to forgive me for choice of material and final finish. I am pretty sure there are commercial versions of this tool, better made and with a nicer finish.
As it turned out, the tools work perfectly well. You just insert the tool into the block, the barbs are pressed back into the body of the connector and the wire can be pulled out from the back of the block. The pictures below show the smaller sized tool. Jeez, I didn’t notice the rust on the little vice until I took the pictures. Winters on the west coast, damp and the workshop is not well sealed….
Update: Google “Molex pin remover” to see some nice and inexpensive commercial and home made versions.
