       I think that you are unlikely to succeed with these materials due to 
temperature and humidity effects. You need a hacksaw, a ruler, a square, a 
scriber, a file and a drill with some bits, for working metal. You buy angle 
Al, cut it up into suitable lengths and bolt / stick it together. It is 
really not too difficult. Have a look at Frank Cooper's SG on 
http://freeweb.pdq.net/fxc/ Is that a particular step or part in the 
construction which is puzzling you?

       Best Wishes,
