Re: Pieter Visser

I've removed the spar box and cleaned up the edges in preparation for the plywood load spreader and final UD layups. I managed to put the spar box back on the wings without too much trouble ;)

Re: Pieter Visser

This morning I sanded the inside area on the vertical spar planks where I had put the flox bead and did the 4 layers of 410 bi-ax E glass layups, finished with peel ply. It worked out perfectly ;) The glass cut pattern for this is simple: measure the middle from top of front spar plank down the trou...

Re: Pieter Visser

Removed the peel ply from the spar planks and sanded the areas to bond for the spar box. I then checked the alignment with the laser and fabricated the foam spacers for the spar box layup, which I put in place with packaging tape and also added added a flox bead in the corners. I won't have time to ...

Re: Pieter Visser

Set the wings up with zero incidence and correct dihedral and then glued in the wing spar bushes. All well but I found that there is slight misalignment on the rear spar plank and it takes quite a bit of force to get the wing bolts in. Overall I'm happy with the result and the 103mm turned out to be...

Re: Pieter Visser

Done the shaping ;) Now need the AN5 bolts to complete this job. I will need a slightly longer bolt as my layup is thicket, so AN5-22 should work well.

Re: Pieter Visser

To make the elevator bracket the simplest way was to take the bracket drawing and to get it resized to the correct scale through trial and error. Then cut the out the template, which I changed slightly to make it simpler and it will add a bit more strength where the alu parts did show hairline crack...

Re: Pieter Visser

Setup the angle grinder with a 1mm steel disk on the workbench at the correct height to cut the elevator pulley on the silver cut lines I've drawn. Once this was done, I removed the foam and pulled off the bottom layer of peel ply to get the part material free. The general rule of thumb for 300-400g...

Re: Pieter Visser

This morning I handed in the bronze wing bolt bushings to be shortened, both to a length of 101mm. I should be able to pick them up sometime this week, which means I will start cutting glass to do the layups of the carry through spar :) Not done much else... did extend the cut lines of the elevator ...

Re: Pieter Visser

Made hard board templates for the aileron bell crank and the rudder pulley. Then cut a section of polystyrene for the pulley bracket and made a carbon layup: 11 layers 300gr bi-ax carbon. Before the 12th layer, the resin started gelling, so I stopped on 11, but this is one SERIOUS layup! Rolled out ...

Re: Pieter Visser

Glued the bronze wing pin bushes onto the rear spar plank, so not a big work day, but at least something was done ;) The flange areas of the bushings are put against each other for this clamp and cure to put pressure on the busing when the planks are clamped. The front plank and bushings was already...
