Hi Rob,
I don’t know anyone who can cut copperclad strip economically, but I do know that various regulations have made cutting materials like that very costly in terms of protecting employees from the dust. One of our long-standing suppliers had to eventually turn down our orders for cutting Tufnol sheet into strip (nothing to do with model railways though!). In the end Tufnol themselves machined it for us - I suspect they realised that if they didn’t, and no-one else would, they’d lose sales of the sheet. It cost an arm, a leg and a couple of kidneys though, and took months!
It’ll be a shame if our copperclad strip becomes unavailable. I still use it for flat bottom track, and I also rather like building track with Masokits chairs. If only there was an alternative, innovative new solution to track building in the pipeline

Cheers,
Paul
