So almost seems to fly by instruments.
I have greatly helped the dimensions obtained in this forum in that they can be contrasted with the ones I had.
I have the intention to develop a design with construction details before starting work so that all information obtained is summarized in that drawing.
And obviously I'll put at your disposal in this forum.
To do so would need to clear some doubts.
I've seen several pictures where the arches are just resting with the back edge of the body, but others stand the arches.
According to the distances provided by Wes regarding the location of the rear top bow stowage, (dim "A") arches protrude 1 ". This is correct?

The second arc that folds over the principal, the total size of the arms is 32-1/2 ", but assuming that the distance from the end to the bolt hole is ½" (half of the ear) according to this photo

would be the distance to the outside of the bend of the tube, 32 "

means this is not the same distance from the hollow of the ear on the main span, as this is 32-1/4 "This is correct?
Another observation I have to do on the bow folding, it seems that there is another tube or sheet in the main pipe, in the end crushed.
I guess it's to give more resistance in the connection end.
As this photo shows several thicknesses, I can not tell if they're three or four.

Anyway, I need to know the total thickness "E", and the diameter of the bolt.
I would also like to know the precise dimensions of the rear top bow bracket.
