I made the mount out of 1/8'' x 1'' 6061T6 aluminum. I actually made it this way to allow for enough noticeable strain to be picked up by a strain gauge. I calculated the dimensions of the mount by using the maximum thrust of the engine (97N or 22LB) in order to get about 450 micro-strain. So there won't be near enough force to cause the mount to fail. Thanks for the idea though!
