Why not just a pipe clamp? They attach to black gas pipe and can easily to
made to the length you want. In both cases won't weight be an issue?
Instead how about some 1/4" channel ? Put it in a piece of of plywood. A
little more money. But I think the prices in the link are Canadian.

The other thing with a lens that heavy you're going to have to build the
front strong but that's obvious I guess.
If you check the leevalley there is various jig hardware that is standard
1/4" size. Use it for ideas.
Front rise would seem easy. An oversized lensboard in a couple of grooves.
Put some sort of system to hold the board in position. Wouldn't need to be
more then pegs.
