Tracy Crook used a couple from a junkyard, 'cause he got them for $5
each. He was going to just use them for sizing purposes, but they had
the unfortunate quality of working very well, so he just kept them.

Most builders have just sort of followed a proven design. It's cheap.
It fits. It's lightweight. It works. I don't know if there is a better
deal in aviation.

Yea, makes sense. Don't break it if it ain't fixed! g

I got to talk to Tracy a couple years ago, at OSH, and checked out his
setup. Can't beat success. I was also impressed with some of his solutions
of sealing and strengthening the hose attach fittings on the GM AC
condensers. g
