Title: Motor mounts ?
Post by: Terry Bolin on January 06, 2008, 04:45:18 PM

I have a couple of questions about the type of wood motor mounts are cut from.
1:Will red oak be hard enough? I have some left over from projects around the house but seems like I remember hearing the words: "Rock hard maple" in the past
2: What are they using in the Brodak kits?
Thanks!

I have found the oak to be too soft and apparently porous to mount an engine directly.  I can be used under a doubler as in a profile.

I have been lucky to find maple in various sizes still in stock at the two local hobby shops I go to.

I am really not up enough on the different woods, but rock maple has been the old reliable.  With aluminum pads I guess others would work. ?? ?? ??

Seems rock maple just has the right characteristics.

Oak is beautiful for coffee table tops, but far to soft for engine mounts. Don't even consider it. Maple is the way to go.

I may be wrong, but it looks like some of those terrible motor mounts from overseas on many ARFS are red oak or worse, Philippine mahogany.. Too brittle, crushes easy.  God made hard maple for basketball courts and model airplane motor mounts.  H^^
