Flange Stabilizer

I talked to Bieker about my part, and he noted adding something to keep the flange from pumping under load.  Is it really needed?  I don't know, but I didn't hesitate to take his advice, as he is the best in the business.

The fabrication of the foam wedge was a little tricky because the pvc foam isn't flexible at room temp.  As this foam will apparently emit cyanid gas if heated, I stuck it in a cardboard tube chimney and shot hot air past it, and out the window.  Together with a bunch of slits, I was able to get the shape needed.  Once I had it glued in place, I bagged a bit of DB90 over it to create the anti-pumping support.
