Thanks. Interesting things in pics: seems like the pic is of the non vacuum bagged spar and they decided that they needed to vacuum bag it to drop resin fraction. They used peel ply to make good attach points for the ribs. I think this doesn't work well if you vacuum bag? The metal inserted for attach points is surprisingly small. I assume that they surrounded it with extra layers of carbon in a pattern of some sort, but I can't see evidence of that in the pictures. EDIT: ah. wing is not cantilever... doesnt need as much strength at that attach point.....You are not good digger:
Here you go :
It is not easy to see what pattern they laid the pultrusions in. (EDIT: some other pics shown after vacuum bag and curing make it look like he might stack them in the corner??? pics are kinda confusing for layout..) You can barely see them at the root end on one side in the pic. looks like the root end has 4 pultrusions on one side... so 8 total at root end? then other writing elsewhere on other builds say his method is to have even spacing between where he drops to 3-2-1 pultrusions. I assume that this means the longest pultrusion is the one closest to the web.....
Edit: it looks like in the hand layup pics they laid the pultrusions side by side so that they were spread flat on the spar cap. For the vacuum layup they stacked them in the web/cap corner into a compact square shape.
Another Edit: This is the best page I have found on the WayBack machine copies of Marske pages.......
