Run cornice in-situ

I bet they don't skip any molds they make.

I bet they don’t either, just charge the next one two hundred and fifty quid for a “new mould” cheeky buggers

They do !

They do !

Then they're a strange bunch. Most workshops have stacks of previous molds.

I’m not sure about the plastic, if it gets scuffed you would get a line in the run. I suppose it could be ok for a cove or an s shape cornice, but if it was a Victorian straight run with a bit of detail say a drip member zinc or tin would be a lot better and you would get a better finish on the Cornice and keep the details sharp.

Also think if you used it as a muffle the plastic would chip when you knocked the casting plaster off the mould.

I can cut and design plastic templates no problem at all

No it would start to wear away as the plaster hardened as you run it thru, even the thickness of a fag paper every time , it would just build up, and I wouldn’t get a sharp finish

Good point mate

Because it needs to cut the surplus off without dragging. A bit like how a sharp feather edge is better for ruling off S&C.

Ah I see... never done any fibrous so it's all fairly new to me
