For my next project I intend to make the track using copper-clad sleepers. Since the sleepers will be hidden I don't really care what they look like or what size they are. However my stocks of copper-clad strip have depleted, and it is not the sort of thing you can pick up in a local model shop! It can be bought by mail order but generally comes in packs of 20' (not as one length of course!), which works out quite expensive when you consider I probably need about a quarter of that.
I managed a trip to Squires last month (the wife needed something from Bognor so I took the opportunity!) and amongst a pile of bits and bobs I got a sheet of copper-clad board for about £1.50, thinking I could cut it into strips. However it proved resistant to all known knife blades - this is tough stuff! Then it struck me - rather overkill but perhaps the power jigsaw could be used? But how to cut a small, brittle board with something as large and crude as a jigsaw?
The photo shows how. The copper-clad was screwed face-down to a piece of board (more of that PVC plastic I got for free in this case), which could be held on the bench, and support the board during cutting. In the end I put the screws into the bench too! I managed to cut a dozen strips - not very straight or even, and a bit rough, but fine for my needs - plus the last bit can be cut into larger slabs for board and cassette ends. Sledgehammer and nut? Probably! But it worked.
