Have a look around on junk stalls.tip recycling centres etc for brass door plates(the oblong ones you push aganst) or kick boards,they are usually cheap and and quite good to manipulate.

Regards

Phil.

I need to make one for my Robinson and will use whatever I have 'in stock' but I guess something around 20 gauge would be reasonable compromise between ease of folding and a solid look.

16 SWG or 0.7mm is easy enough to work, just make a pattern in alloy to tap the edges over with.

Thanks for the replies, a quick search on Fleabay and there's a 900mm x 900mm x 1mm thick piece for 8 a couple of miles away, does that seem a good price and would it be suitable?.

At 8 it seems a bargain....depends what grade of brass sheet it is...
At 1mm thick thats 40 thou as opposed to the 16 swg which is around 1/16"- 62 thou....should be ok.

When it comes to bending, you should anneal it first....

Not too difficult to do the radius corners too with a good pair of snips. I'd load a drawing for You but I'm battling with a "coal-fired" laptop while I await my new PC tower's arrival, and it doesn't have the driver for my scanner/printer!!

Right, dug out my apprentice training books from the 70's and will do a bit of reading if it's quite on nightshift tonight.
