Re Stuffing Tubular Capacitors?

[pwdrive]

As most will know, the end seals of the old metal tubular capacitors are sometimes difficult to salvage when restuffing, in the main they are black in colour both on the double ended and chassis mounting single ended ones.
I was wondering if anyone has tried casting their own with high temperature silicone rubber?

If not I might give that a go come winter time when I'm back on the case, that stuff should take soldering iron temperatures ok as I have used it in the past for sealing flue joints up.

Hi,

Good luck Lawrence with the re-stuffing.

I used modellers clay for my end caps; the clay was rolled out to the required thickness and I used a homemade punch to cut the caps out with; these were then baked in the kitchen oven to dry the clay. To finish I used a common black instant marker pen to colour the caps.

I hope this is of use.

Kind regards, Col.

Hi Col, I don't think that would work for metal tubulars because of the retaining lip but yes good tip for paper/cardboard tubulars.
