The tail lights
are 7"dia. Grote 60 diaode cartidges, Part no.53422 from Peterbuilt Pacific Inc.
at $86.52 ea. plus taxes. They are totally sealed and are guaranteed for 100,000 hours. They are so bright they almost blind the driver behind you at night.
Having had a number of horse and snowmobile trailers over the years and the lights
never working when you go to use them these are the greatest invention since sliced bread.
I used a big piece of carboard and scribed the body outline onto it for a template. The frame its self is fabbed from one 20ft. length of 1"sq. alum tubing (1/8"wall) Just enough to do the whole thing! The tabs and plates are from scraps of 1/8"& 1/4" I had. I bought a 12 ton bottle jack tubing bender from Princess Auto and carfully bent the tubing to match my template.
When I had it to shape and all the pieces cut I had a shop weld it up.
Then I bought a tube of Silkaflex-291 Fast Cure Marine Adhesive/Sealant & Bedding Compound from a marine supply. This product is used by alum. boat manufacturers to glue alum. boats together rather then welding them. I tried several construction type adhesives but they were usless compared to this product. I only used about half a tube to glue the 2 skins to the frame. Man does that stuff bond!
Alum. square tubing- $50
Tube bender- $269(I took it back)
Welding frame- $50
Fiberglass, Bondo and paint- $20
Hope this helps
