RE: Motor Mounting... Old School?
I have been known to still use both methods. It is difficult to get two separate wooden beams on the same plane so that there is no twist applied to the crankcase when it is bolted down. My preference is for nylon engine mounts (glass filled, actually). Metal mounts are okay, but I'd rather break a nylon mount in a crash than a crankcase when bolted into a metal engine mount. Fortunately, crashing is a rare thing for me, but it does happen on rare occasion.
Wooden beam mounts are cool in that if you want to change engines with different bolting patterns, all you have to do is to fill the existing holes with small hardwood sections of dowel that has been epoxied in place with lots of epoxy. Once cured, sand smooth and begin all over again. Of course, it helps to have fuel proofed the original beam mounts with epoxy.
