John,
Don't really have any details. It needs to have a pretty sharp angle to work right and not have the handle way down of the floor when you lift. All I used was square tube iron from the local hardware store, estimated

the angle, cut and welded it together. I gas welded but a wire feed would probably work better (I don't have a wire feed unit). The lift pegs are just carriage bolts (I think maybe 3/8) with a hole drilled through the tube iron and a nut holding them in place but they could be welded too, except then you can't move them. There could be a couple of different holes to accomodate different size tail wheels. I put plastic tubing over the bolts but probably not necessary. One other thing, it might not be the worst idea to reinforce the angle with a 'gusset'. I didn't but am watching to see if anything bends. So far, so good..........!! Used it today to pull the L16 in tail first and it worked fine. Hope this helps.
Mike
