I decided to have some fun today and make a pattern for some thing I have been thinking of casting.

I used some lexan that was given to me. I pinned two pieces together so I can cast in sand.

Started roughing it out with a 1/4 inch cutter.








Then I made some horizontal passes with a 1/8 inch ball nose. Can see more detail coming out.






Then vertical passes .006 on center for a few hours.






Then to the manual mill to remove the extra off the bottom

Nuthin' but COOL !
Awsome don't even come close.
Ok, so now you need 2 carbs. And what are you going to use for a belt ?
Just put it on as a dummy, no rotors necessary (unless you got plans for em')
Way to go Steve !
Gotta see this thing blow some smoke.
Wicked !

I made 3 carbs a few weeks ago. It will use a 1/2 inch wide MXL belt. I have 3 lobe rotors planned. It will be no dummy.

Any reason why you decided to make your carbs rather than to use something like a walbro off the shelf?

Walbro would be way!!!!!!  to big. Alot of the real small RC carbs are made to flow nitro. Also couldn't find one that looked like a holley.

Not alot of progress but progress none the less. The oil pan is offically done. I drilled the holes for the motor mounts. I also added a hole with a pipe plug to allow for checking the oil level. Now both of the boys are standing proudly on there legs. I mocked one up just to get a feel for how big they will be. SMALL!!
