How to cut UPVC trim lengthways?

Sep 14, 2017 8 Replies

I want to cut quite a few flexible angle trims lengthways to reduce their width. What is the best way to do this? Clamping between two lengths of 4x2" and then cutting the excess seems like the way to go but cut with what? A hot wire cutter would be good but I suspect it would be too feeble.



Any ideas?



Thanks

Absolutely right to do the clamping as you propose.

Sanding disk on angle grinder, disk sander, jigsaw, circular saw, router, plane (manual or electric); file; rasp; hacksaw.

The problem with the power tools is is that the high sliding speed will tend to melt the plastic.

If there is not much material to remove, a "manual" tool may be best. If there is more than 5 mm or so then a saw of some sort might be best. Between say 2 mm and 5 mm I would go for abrasive (keeping the pressure down to avoid too much melting if using a power tool).

+1 When I was cutting acrylic with a jig saw at slow speed there was some melting on the cut edges.

Hand cutting is the way to go with something like a very fine tooth floorboard saw

A fine toothed blade in a circular saw used gently (to avoid overheating) from the bottom face?

Fine toothed panel saw used from the top face?

(I've used both to good effect).

circular saw works nicely on PVC [always smells buttery to me while cutting]

Thanks all for the suggestions. A fine toothed saw is what I will try, thanks for the link.

Excellent. Not quite the same, but I have been cutting and trimming fairly thin Perspex type material, and a fine toothed hand saw made the job simple, if perhaps a little long winded. Delighted with the results, though.

Probably better off with

They also do upvc saws that work well but cost more
