Re: [TCML] Cleaning Copper Primary Coil (with Muriatic/HydrochloricAcid)
If you do not want to spend much money or time you can cut up a cheap HDPE cutting board. To make the holes you drill the size you need to match the OD of the copper. (drill so that the edge of the bit is almost touching the edge of the HDPE). Then, use place a slightly smaller bit through the hole and pull it through the thin side wall.
Not the best method but it works.
Here is an example.

FYI, a router bit or sideways cutting bit in a drill press works pretty well.
