Non Metallic Plumbing Fittings

Non-Metallic PEX Fittings
Pex piping was one of the discoveries I made on the Lunar Lander  project. It is used in place of PVC especially since it can survive freezing. The plumbers used metal joint fittings, which must be destroyed for the piping  to be revised.

At the IBEX conference I found these non-metal pex clamps. www.flairit.com  www.iplumb.tv .They can be installed with only pliers instead of a crimping machine that resembles bolt cutters. An improvement on an improvement. Made in Chile.  There, better pic.

Chris Anderson’s 20m Catamaran

We finally get to see some pictures of Chris Anderson’s cat that he designed and is building. This is going on in New Zealand. North Island I think. This is a CM (cylinder molded) developed plywood  vessel. Chris goes away back on the process. In fact he is in the original CM video.
If I may throw in a bit of bio: Chris led the team that designed the fly-by-wire controls for the Boeing 777. I’m surprised he has not also been interviewed by Wolf Blitzer this week.
Being from the antipodes, Chris did not know about Autocad, so he designed and used his own 3D modeling CADD software.
This unit will have 6 unstayed masts. I recall seeing the rig arrangement fastened to the top of his car; he was conducting tests.

Good stuff and great to see it move along.

A little hull layup…

Upgraded the video on this a bit: The layup on a 68′ cylinder molded hull currently under construction in Roatan: it’s speeded up quite a bit, this is about 25 minutes of real time. the half hull panels are approximately 11′ x 71′ – 4 layers of 3mm plywood and 33 gallons of epoxy.
