Whats wrong with a hacksaw with a 32tpi blade? The hard bit is holding the damn thing stable without distorting it.
hi - i need to cut a pressed ally mudguard neatly, have been told that the best tool for the job is an abra file blade.
cant find one anywhere - do you lot know where i can get one?
Re sawing through soft ally plate; I was taught once to fill any shape with plasticine/putty and saw through that so it holds the ally in place and shape whilst you cut.
would a cutting wheel on a dremel type tool work for this?
it is a curve to allow an exhaust pipe past the bottom corner
A cone cutter mite be useful or even a holesaw. You could use a scraper to get a neat finish.
Abrafiles would be stocked by a tool merchant like Buck and Hickman.
I have often got good results on alloy with tools meant for wood. Drawfiling produces a reasonable finish which can then be improved with reducing grades of wet and dry around a bit of broom handle.
