The weather cleared yesterday afternoon and I was able to do the sanding down of the tube.
After I brought it back inside, I laminated the 3mm Coremat, using about one third of the amount of resin that it should be able to absorb. I painted the resin onto the carbon fibre only, as I wanted the outside of the coremat to remain dry for wrapping. I first wrapped the coremat with baking paper, as a barrier layer, and then with masking tape. After about 5 hours I removed all the wrapping. Today I will saturate the coremat with resin and wait for the next weather clearing.
BTW does anyone have any good internet links pointing to carbon telescope tube making? People seem to be a bit shy about revealing their techniques, or at least I didn't have much luck finding good information.
