Ok so this morning I was mucking around with my reflector (thinking of selling it, etc.) and collimating it.
Well it took a dive from the piano stool and earned a dent on the tube. Nothing that affects functionality but it looks bad.
I pushed out the dent as best I could with some wood blocks and a C clamp but it's still unsightly.
Now I want to replace the tube.
So.. where can I get..
1) a 10" diameter paper or phenolic tube like a Sonotube - I can impregnate it with epoxy to strengthen it
2) or where can I have a carbon fibre tube made (RS Singapore sells sheet but it's expensive - $160 for a 30cm x 30cm sheet)
3) fibreglass sheet. In a previous hobby I made boats, I know fibreglass cloth can be overlaid on a paper tube and impregnated with epoxy to make a very strong structure.
Wanna make a scope? Or better still, grind a mirror yourself. Or, you have some good tips in making a really useful accessory? This is the place to show what your hands can do...
