Re: Cutting PVC trunking cleanly...

[Paul Gale <groups2@xxxxxxxxxxxxxxxx>]

If you don't want to spend anything/much, you could always make up a
cutting guide/box.

All you need is three bits of timber nailed/screwed together to form a C
section (just like the open trunking shape) and so that the trunking is
held securely. Then cut a 45 degree slot in the uprights.

You then use this as a guide with your existing saw to cut nice neat 45 deg
angles (or 90 deg angles with another slot). Pretty easy to make.

You really need to make sure the saw is sharp though for best results and
has fine teeth / high teeth per inch.

Paul.
