OK I think you just lost me. I'm not sure where you got the 120 bucks. I made my mount for about $8.00 worth of material, including the dave brown mount. The neoprene well nuts are a bit difficult to track down (my neighbor who helped with the mount had some in his shop) I didnt use the fuel tubing as in the piedmont mount, just have the well nuts in 1/4" holes, and a 10/32 hex head nut to hold the mount to the nuts. Washers are added as necessary for right/down thrust. 4 6/32's to hold the engine to the mount. I'll try to snap a pic of the mount on my pattern plane to show you how its done (since the engine is out of it). It is much simpler than it sounds.
