bubbagates your bad !!
Seriously, really appreciate everyones reply. I'll get the chain saw out and fabricate a mount from one of my old Beech trees as needed !!
I really can only see that the advantage to mounting the engine solidly so that the entire engine is snugged to a solid (flat surface)firewall or mount is purely to control "excess" vibration and not as a matter of controlling backlash and torque in lieu of a good quality standoff like the SWB stuff, especially when the standoffs are used with solid spread washers on both sides of the firewall. Thats pretty solid as well.
Even on a solid firewall mounting you are still fastening the engine with 4 - 1/4" bolts, same as the SWB stand-offs, right ??
Am I missing something here ?? I know the DA guys obviously had to do the homework, just trying to figure it out.
