Hey Flipflop thanks for the advise...I have two HN engine mounts...I'lll modify one for the Polan...by the way, how or what do you use to machine the aluminum with...like the fins or the flywheel to get a nice surface...I've tried the coursest grinding stone but they all just load up with aluminum...I have a little cutter for my dremel but it takes for ever and it reminds me of the DENTIST!!! TIA

Ron
