etails about the oven? Way back when I formed plexi after heating in a box with about 4 light bulbs...
I've been doing some vacuforming with 1/8" acrylic, using a machine
much like this one...
Years ago I was hanging out with Jackie Yoder and he was explaining how he bent the
lens for his "in the wing" landing lights. Just a plywood box with an old heating
element (I think he said he scrounged it out of a dryer). Takes a few practice
attempts to get it right, but acrylic is cheap.
For those who were arguing the materials: Most aircraft "glass" is acrylic (plexiglas
is a brandname for acrylic). It's not quite as strong, but is easier to work and can
be reheated (theroforming). Some people do use polycarbonate (lexan is a trade name
for that). It's much stronger (bulletproof even), but can scratch badly. It's harder
to work (thermosetting).
