Re: Cutting PVC trunking cleanly...

[Steve Morgan <steve@xxxxxxxxxxxxxx>]

Phil,

A saw is almost always going to leave a burr, either because it's too slow
or it melts the plastic.

Try a mitre guillotine, as you can't beat the accuracy of a nice sharp
blade.

You can get benchtop ones, though you might struggle to find one big
enough. I've got a Morso foot operated one which is the scariest machine I
own! Got any picture framers near you? They'll undoubtedly have a Morso
too.
