came into this thread on base metal source late - there's a supplier
'www.micromark.com' (actually a model train supply business) that
has brass, copper, aluminum strips, angles (L-shaped), round,
rectangular and square tubing as well as solid rods. they have a
pound assortment of 'odds & ends' - of all of the above on sale now
for $15.50 + s&h.
micromark has a great hard copy catalog. after buying a lot of items
from micromark, i can recommend them - they have good quality items.
who owns no stock in micromark -
