my wife says I am not finished with the one I have but the frame it rides on is an old boat trailer which is about to get a 3rd expensive repair. And the cost might be better spent on a new rig.
Designing a trailer leads one is all directions.
I was looking at boat building today realizing that many bowed parts are several thin planks bent and then glued together.
Other wise one would take a wide plank or plywood and cut it to the same one needed.
The curves I have done to this point cutting plywood sides for the trailer attaching wood bars between each side then using 1/8th thick ply sheets glued to the bars in the shape of the angle. Meaning the front and top of a teardrop trailer. which is the way I intend to do the Cross bow only the 1/8th sheet will go left and right.
Then there are things I do not know how to do and want to figure out.
I have always loved the trolly top much like Doug has does on two of his teardrop trailers. What I would like to do is more like the old 1960 VW van top, in some those the little windows opened too it think?
where the windows on top are between the side and the center of the top is a little higher and flat so I can install a hatch or fan.
The part that concerns me is front top where the top little window area meets the front top???
I have seen great idea for new cars and when they come out they do not look anything like what was drawn, I can dream but it will take some time to work out what i can and can not do.
