McCulloch steel engine mount

Post by justin_cosgrove » Sat Jul 31, 2010 10:07 pm

I've been looking around for one, but after postage to NZ the price goes crazy, so I have decided to make one, I'm a fabricator so this is no trouble for me, if anyone has one could you please make me a scetch with acurate demensions :oops: I would consider it a big favor.

Cheers,
Justin

Justin,

No "real" fabricator would ask us clowns for dimensions... he would lay it out his own way :lol:
Just kidding... some questions for you.. do you want to build an angled mount or one that holds the engine with the center line of the bore parallel to the ground? Do you want to hold the motor by the four stuffer bolts like most mounts or do you want to grab it by the four mounting bosses on the side like the Rupp Uni-Mount setups did? Or do you want to mount the motor with the head up and carb forward as is done on most sidewinders?
I have all kinds of mounts I can measure for you but you need to be more specific in the type you want to build.

:lol: :lol: :?

I must admit I could make something similar from photos, but I want to make a repro ;)

Good question about the style, I had something in my head thinking everybody else knew what it was :D the mount I have been thinking about is the angled mount bolting to the motor by the stuffer bolts, I imagine this is the most popular type too.

That would be great if you could do that for me, and maybe I can do it in autocad and post it in pdf for others ;)

Cheers,
Justin

Justin,

The two most common mounts of the type you described are 30 degree and 45 degree angled mounts.
Do you have a preference for the angle?
If you go through some of the pictures on this site you'll see plenty of examples to know what angle you like best. I have both types to measure so let me know which looks the way you envision the mount and I'll measure one for you.
