Hi Bill:

I've done it twice...the first was the SV-40 (Vector) it work out well but I had to make sure the tank had shimming on the sides diagonally so the skew would stay in place (for nice cut-off)

The bolt mount needs to be very secure.  In the tank, I used a piece of tubing and grommets top and bottom to increase the solder area.  I used 4-40 screws instead of the nylon larger bolt that Ted drew in the TP.

I started with my Katana the same way but could never keep the bolt tight.  It vibrated around and eventually (250 flights) the tubing developed cracks and leaked.

THis spring I took it all apart, plugged the holes, and put in the ply clips and cross bars that is the typical mounting method.

A single bolt does not seem secure enough for the 7 oz tank.

FWIW

Well, I thought I had commented, but apparently not.  I bury a fore and aft hook in the engine mounts and rubberband the tank in.  I'm not sure my soldering skills would do the job with the bolt through.

Yep...mine went about 350 flights before it began being a problem.
