GPO-3

I got the GPO-3 fiberglass sheet from Online Metals dot com. I hoped to substitute it for the more expensive G-10. Looks like it worked. It is smooth like G-10 though in the picture above it looks rough.
This 2 foot by 2 foot sheet was $10.  Picked it up myself.  Compare to same size G-10 at McMaster Carr at $47 plus some $20 shipping.
The red probably means it is phenolic.  Both of these are fire resistant.

The panel looks like it was made with chopper gun, but it will be used for low load applications, so no worry.
They did used to be a friendly neighborhood supplier. They have been bought by Thyssen Krupp and have a new corporate bureaucracy feel now. Good prices though.

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.
