I told y'all I'd order a fiberglassed phenolic tube from http://www.publicmissiles.com as a potential lightweight but strong tubing solution for my TMB175 project. Well it arrived today, and I had no idea what to expect when I opened the package. Let me tell you, it's awesome !!

The tube arrived smooth as a babies bottom, is pleasently light (I'll weigh it tomorrow.) The fiberglassing job looks superb to me.

Here's a couple of pics:

You can see in the edge detail it looks like a totally uniform layer of fiberglass (actually 2 layers I think.):

Also the publicmissiles.com custom length cutting job looks great. Haven't tested it for squareness yet but the cut looks super.

Now it's time to get the aluminum endpieces turned which will fit into the tube ends.

Excellent Mike,
I had a feeling that the strength and precision would be good because it was for rockets. Those things haul butt!
