Mould for concrete chimney cap.

[mark vincent]

Where can i get a mould to make concrete chimney caps, the sort that are used to cover in chimney pots that are no long in use.

I was thinking of trying to make a mould my self, it sounds simple but the cap has to have vents in it to allow the chimney to "breathe"

Why not just buy one? (not a mould)

Failing that can you show us a pattern or picture of the design you want. It's difficult to suggest anything without knowing what it looks like.

should be able to pick them up from a salvage yard for around a tenner each.

If this is the model the OP is after I can see why he wants to make his own. Three of these in clay cost me nearly £120 last year.

That said it would be a tricky job to make your own reusable mould to produce then (I'm thinking cut up old plastic buckets here...).

If you can get them 2nd hand I would.

Can get plastic caps for about £10 - £15 each.

The clay pots as pictured in this thread are £25 each, i have 6 pots on my chimney, i have been told that you can cover the top of a chimney pot with a bit of slate bedded in mortar.The problem with this solution is that the chimney can't breathe and this can cause condensation.

they used to use the slate method years ago and vented it by making a hole in the slate and inserting a 18" piece of 15mm copper into the hole and bent it down into the shape of a swan neck to prevent water ingress, the pipe was splayed flat on the underside and a mortar collar on the top..........it works.
