Title: Mounting engine on alum. pads ?
Post by: Rob Killick on February 10, 2008, 11:45:21 AM

Hi ,

I was looking at the photos of Randy Powell's motor mounts , on his latest post and was wondering what is the best way of securing the motor to the pads ?
Should I drill trough holes and blind nut the underside of the mount (with LocTite) , or tap the aluminum pads and lock washer and LocTite the screws ?
Thanks in advance .

Hi Rob,

In those pictures, the aluminum is bolted to the maple. The holes through the aluminum are tapped, there's a short piece of carbon fiber inserted through the maple and a blind nut on to secure. It's a bit of a trick to get the threads from the aluminum and the blind nuts lined up, but just takes some patience. The aluminum will be drilled and tapped for the engine when the time comes. I've done a bunch this way and so far it works quite well. One of the big, positive aspects is, it makes it pretty easy to change engines. Just cut another set of aluminum mounts and bolt them in.
