Well, I guess everybody's seen the FoamStream drawings in my Album .... Really excited about this build ! In the planning and materials acquisition stage ... Been reading up on Wagon"bows" .... Most seem to be 5/8" X 2" strips 14' long , and made of hardwood ... pre-bent and somewhat pricy...
Needed here is 16' strips 3/4" X 3"-4" , the wider strips providing more surface area to glue the foam sides to...
Problem is going to be finding hardwoods in 16' lengths , not to mention expensive... couple alternatives come to mind...
One , just use shorter 1/4" hardwood strips and just laminate them together with staggered seams ... ?
Two, make thin 1/4" plywood strips and laminate those together ...?
Three, we can easily get #1 Pine here (clear, no knots) even in 16'... Might be thrifty to buzz up a board into strips and use that ... Wonder if Pine is strong or flexible enough ...???
Four, buy the pre-made Wagon bows ($$$) and make a box off the floor to retain the 6'3" inner height..
Five . laminate all the ribs out of Foam ... Thick enough and wide enough should be strong ... enough ... Maybe some plywood "faces" on the ribs???
to be continued ...
