literally to death?!? holy cow. Could you elaborate on this permenantly attached canvas tarp afixed to where exactly on the rack of your 55 and how big was it and what did you do to hold it open and and and...sorry, but I got to have the details...
Yes, the geologist that rolled the jeep was killed. Literally.
The roof rack works like this:
It uses real, live canvas 'cause the plastic tarps disintergrate in the sun and wind, canvas lasted me for over five years.
Regular "J" hooks mounted across the front of the rack, grommets on the tarp hook on, I just left 'em on like that. I planned to cut the little knobby things off the J hooks thread the ends and put nylocks over fender washers to keep it on permanently, never got 'round to it. Down the sides at the grommet points two J hooks one pointing in and one out. Bungee cords crimped onto grommets.
Works like this: flip the trap forward. Load camp boxes, etc, on rack. Tie down cargo with ropes to the J hooks that curve inward. Flip tarp over rack, pass bungee cords under, hook on J hooks that curve outward. Bungees shortened to fit.
Rack has 3/4" plywood deck with 1 1/2" angle iron running fore and aft, gutter mounts attach to these. Cross braced with same angle on top of rack, (except back two, over which the extra spare tire goes, more later), which prevents cargo from shifting fore and aft, ropes prevent side to side shifting.
3 gutter mounts about a foot from front and rear and middle, 4th about a foot in in front of rear to support spare, 3/4" bolt goes through angle and a 10" or so piece of 2" square stock, double nutted on top to hold spare tire.
If you don't want to use a second spare, mount all cross braces on top, and divide gutter mounts evenly. Paint the plywood before assembly to prevent water damage. I used flat black on the bottom and silver on the top, that way if you choose to pull the tarp off or roll it up on the front, the silver helps reduce heat--the FJ55 was spectacularly ill vented. Wish I had a picture of it, but I can't find any That show anything.
That help?
