  • Multi-Section Capacitors - "Empties"

    From Peter Wieck@21:1/5 to All on Mon May 4 15:44:49 2020
    This has probably been asked-and-answered before, but:

    I am looking for multi-section "empties" - that would be the can and the phenolic wafer - so I can stuff them myself without the cutting-and-gutting otherwise necessary.

    Anyone aware of a source?

    Thanks in advance!

    Hayseed Hamfest makes replacements. Maybe they will sell you the empty cans?

    Good start - I will ask, and report back.

    Good luck. I found some aluminum tubing that is very close to the four section, but no way so far to make the plate with the ground lugs. A local Canopy manufacturer uses it for their art show products and six inch drops go back for recycling. If I can
    come up with a low cost ground plate, I will offer them and the tubing. They fill several 50 gallon plastic barrels with scrap, per year.

    Hayseed does not sell parts - they cite the raw costs for just the can and base at close to $20 retail.

    Working on the source for the eBay mounting plates. No cans, but a nice 4-way base and grounding options.

    Thank you!

    But, I do keep a Unimat Lathe/mill combination - and I have sufficient tooling to do this sort of thing. Being inherently lazy, my preference is to support other cottage industries other than my own, if possible.

    Next Kutztown, I will purchase a bunch of can-caps at the BIN table, typically "box for a buck" and make use of my industrial tubing cutter....

    Many thanks, however!

    A cutoff saw with a fine blade does a better job on tubing. That's how the Canopy company gets nice, clean cuts with no scratches on the tubing.

    I wonder if the Chinese capacitor companies would sell empty cans of the right size? For instance:

    Zero Manufacturing makes many sizes of deep drawn aluminum cans, but they aren't cheap:
