Being a bit stymied by the lack of Styrene elbows at the Evergreen site and a lengthy search of the Internet all I have so far is:
Pegasus Hobbies Chemical plant for pipes, elbows and valves of one size and Reverisco pipe fitting for 3 sizes. Anyone know of some hobby or other site that would stock pipes, elbows, fittings and valves to mix and match pipe work for my underground base? Evergreen has a nice source of assorted pipe sizes but no elbows etc! The hope is to make a few complex pipe maze areas from assorted sizes of pipes.
