Update: I have completed the spider and secondary holder, it's pretty much a standard four vane design with the 3*120 degree spaced collimation screws. The materials are: hacksaw blades for the vanes (teeth ground down), Ply centre hub, and the mirror holder is made of model aircraft balsa wood to keep the weight as light as possible (notice that I used 5 cent coins as push plates on the secondary holder). Photo are attached. Yes the screws will be painted black.
The carbon fibre tubes have been covered with plastic sleeving to protect them and the tube joints and frame members cleaned up in prep for sealing the frame members with clear coat epoxy.
The primary cell is nearly complete, I just need to spray it.
Next step is to mount the mirrors on their cell/holder and install in the tube for a test. I have all the spacings worked out in Newt 2.5 but it is a visual design app so I need to do a real life test with my camera on the focuser to check focal plane distance and adjust if necessary by moving the front frame station forward or backward on the tubes.
Ordered some Nylon/Lycra for the shroud, but I don't have a sewing machine so it will be interesting to see what I can come up with to make it into a shroud. Any ideas would be appreciate.
