motor mount

[Lay26]

.............the speedmaster motor mount's don't come drilled and tapped. i need some tips on installing one in MY ac pro sport 40.

OK, because not all motors have the holes in their mounting lugs the same distance apart because of case width and length. Yeah, it's a real pain in the you-know-where to drill them so that they fit right. Anyone got any hot tips on how to do this?

Make a jig out of a square scrap of aluminium or steel 1/16 - 1/4 inch thick. Measure and scribe straight lines lenghtwise and crosswise that intersect where you want the holes.Center punch and drill.clamp this to you'r mounts and use as a drill guide.

Great Planes makes a nice tool called a Dead Center Engine Mount hole

locator. Part # GP MR 8130 Try it,you'll like it.

Just mount your mount brackets in a milling machine and drill them the right distance from the end of the mount and so the spacing is right . and then hand tap. Scott

Sorry, but a milling machine won't fit in my tool box. If you buy the mounts from Jerry Crowther he will drill & tap the mount for any engine you want. He is a great guy to deal with. Send him an email.

Later!
