I saw these miniature hairspray cans and wondered if they might be useful to build replacements for metal can electrolytic capacitors.

The size is about right and they could be trimmed to size with a Dremel, or even better, on a lathe. Have not tried this yet, but should accommodate some large size radial electrolytics.

I have used copper pipe for cans, because I had it. I didn't bother making a top, I just leveled off the top of the can with hot glue.

They wouldn't work me thinks. The ali is so thin it virtually collapses when you cut into it. Try it with a sharp junior hacksaw.

The old caps used a good metal gauge and I still find them and buy them up at Swap meets as long as they aren't badly dented.

I've always tried to use the original can for a rebuild.. I use a die grinder with a cut off wheel to get it apart..
For the cardboard tube caps, I have used the card board tube from a roll of aluminum foil, wax paper, or some such..
Different sized rolls come with a different sized tube.. Sure makes my wife mad though..

New cans are available from china. I've tried to get quotes, min order is about 400-500 with some.
problem is trying to communicate and get an effective quote together, I gave up.
Its not impossible nor expensive. Still working it off and on.
