Bruce,

Thanks for the input. Yes, I should have done this in the scratch built forum, but being the new dumb guy, I was not aware of the option. I have searched the world over for tiny parts. Small Parts doesn't have the sizes I need in bolts and such (I need a source for 000-120 or smaller). As for the rollers, well I am in the process of making these. I was really just looking for good detailed information on the actual mechanism, or better yet, details of the F-111 flap / slat system. Of course, any help is good help. Thanks.

Les
