The mast is not in this jig when vacuuming. The jig is simply to put the carbon on without touching any surface the carbon might stick to, pickup some dirt, or similar. Not sure about the 'pegs'?
Also, the jig will enable you to put the mast on an angle, any angle you make simply with a few nails (click on a pic, you'll see them). This will obviously work only with some sort of support, as I have SS 6mm bolts going deep into the mast ending in a brass insert:
Vacuum bagging is simple. No magic here. I would strongly advise to everyone, your peel ply must be first and must be 'soaked' with epoxy. That is where the jig kicks in as well, I did put the mast LE on an angle, and than added more epoxy under the peel ply where needed. Gently used my hands over the top of peel ply. When all completely wet, done.
The SS bolts stay on. They are waxed, no issue with taking them out after.
I understand the problem with a 'sag'. And it did happen slightly but way after the blue sticky tape where I actually need to cut the carbon excess. I think this might be due to the carbon setup. If having only a few (ie 2-4), carbon layers and they are all UNI directional carbon, than nothing is opposing to bending forces when applying a vac. Hence it might sag.
I have 45 degrees two layers first, than only one UNI, than big squares tow. With this there are 3 layers supporting UNI not to 'distort' in UNI direction.
Will take a pic of a LE&TE when ready. U bit stuck with other stuff atm.
There is one thing tho, the both mast sides are a bit wave-ish, with a 'wave' square on a LE, every 10mm or so. Not sure why this happened where there is NO carbon in this direction. No idea. You can see that on the above pic, middle right section, strait lines on a vac bag. Where from?
Otherwise perfect.
Hope this helps.
