Motor: Logic

Trying to install the clutch basket into the model motor and hit something of a logic roadblock.

All these things are true:

  1. Installed by itself, drive gear fits correctly onto the crank and engages the primary driven gear.
  2. The drive gear installs correctly into the clutch basket.
  3. The clutch basket installs correctly onto the crankshaft without the drive gear in place.
  4. BUT... with the drive gear installed in the clutch basket, the assembly will not mate with the crankshaft.
The only thing I can figure is that with the drive gear in place, it's putting the center of the basket slightly off center so it can't line up correctly to engage splines on the crankshaft.

If that's the case, though, what's the fix?

[2/3 edit]
So, the fix is that you just unpack the basket, repack it, and viola.  I guess the plates were just a little off center.  Still not sure how to guarantee they line up the first time...

Motor: Engine Stand

Decided to mount the Model Engine on the wooden stool I'd been using to mount them into the frames (before realizing they didn't work once the coil was installed).

Drilling the four holes to hold the engine was easy, but then realized the oil plug needed its own hole to get the bottom flat against the stool.  Used the dremel depth attachment for the first time along with the metal cutting bit to shave it out.

Worked a treat.
