Phenolic Tubes:
I am offering to the telescope making community an excellent alternative to cardboard sono tubes! Kraft Phenolic tubing is a resin impregnated paper that is cured in an oven under pressure. The resin makes the tube much stronger than paper alone. The big bonus is that it also becomes moisture resistant and dimensionally stable. The perfect combination for scope builders! It is also much lighter than a typical sono tube. Recently several telescope makers have purchased our tubing for making Dobs and they loved it! Now it is time for us to offer it to the rest of you. These are the only sizes of phenolic tubing currently available. They can be cut to length for you upon request.
PT-6.0: 6" ID x 48" long. ~0.074 wall 36.9 oz. $32.95 each
PT-7.5: 7.5" ID x 48" long. ~0.080 wall 48.1 oz. $38.45 each
PT-11.4: 11.4" ID x 48" long. ~0.125 wall 104 oz. $76.15 each
We also offer fiberglass wrapped phenolic tubing for superior strength.
Carbon Fiber Tubes:
We manufacture custom made carbon fiber tubing up to 48" diameter and up to 96" length. For diameters larger than 15", we offer very unique foam core carbon fiber tubing. These tubes have a 0.18 layer of medium density foam sandwiched by several layers of aerospace quality carbon fiber. Hardpoints are added during manufacture to your specs. These tubes are VERY light weight, rigid, and dimensionally stable. These tubes are ideal of large observatory grade scopes. Email for more info and shipping charges. Please note that these tubes are of the highest quality and built by professonals. Serious inquiries only. Photos and samples available.
I may consider some trades for high quality scopes and parts as well.
Thanks,
