Flamestop

I just got some samples of the flamestop intumescent paint. http://www.flamestop.com/documents/Flame-Stop-IM.pdf

I want to be able to try painting it on a part and then covering that with the 2 part poly final paint.   This will be far better than applying toxic phenolic onto the inside surface, wearing a moon suit.   Or mixing toxic bromine in with the epoxy.

I will report on the results.  It looks like a great way to get code or rule compliance in galleys or engine rooms.

Sarabi Mast Update

Mast guru Ted van Dusen might be building the new mast for Sarabi. The reports we get are that the mast thickness at the upper bearing is between 1/2″ and 3/4″. Is odd that it varies that much. Just mic it and be sure?
Ted ran a FEA on it and came up with more like 1-1/2″ wall thickness required.  I may need to note that I did not design the mast for Sarabi, nor did Forespar.  It was all done at Aero.
That tracks with my work on Alex’s mast where first principles gave one wall thickness and the FEA required almost double that.
