- Dec 4, 2006Following up on Loren's suggestion, there is a way to take the work
out of this and prevent accidental cut-throughs especially if you
have more than 1 shell to shave. A jig can be made from a Dremel
drill press and when precisely aligned will easily shave the shell
walls to clear the motor bulge. Shims for adjusting the stage tilt
and a means of mechanically adjusting the guide positions are needed
to carefully align the jig. My version is made out of wood, perhaps
heavy styrene might work too if anyone wants to experiment.
Considering the current squeeze in this list photo section, I have
put a couple photos in the companion Z_Scale_2 photo list to show the
general idea. For those not yet members of the Z_Scale_2 photo list,
initial sign-up and moderator action is required to keep out
The album name is 'An MTL F7 B Dummy to Power Milling Jig'
The powered chassis needs to have it's shell locking tabs on both
sides of the fuel tank trimmed flat. Thin shims can be added under
the chassis end screws to raise them slightly to grip the inside of
the B shell so the chassis does not fall out when picked up. Flat
toothpicks can be inserted to release the shell afterwards for
The leftover B chassis can be filed or ground round at one end to fit
the leftover A shell and make a dummy A unit.
