:D

Thanks again peeps, I'm going to try a good hacksaw and see how I get on. I don't mind hard work as long as the cuts are accurate!

I hired a TCT mitre saw from A-Plant in Wrexham. Cost less than £50 and I cut the whole chassis in a couple of evenings. Sure I had some little pieces lefts over, but I just used a hacksaw for the one or two extra cuts.
