EC750E boom drive part 3

Fitting the new narrower cylinder drive still has overlap problems. At 12 stud width it is still too wide to fit in the maximum width that the model can handle before being way out of spec.
Looking at this photo it is clear to see how the turntable overlaps the space for the cab.

Time to rebuild the boom drive yet again using the half width gears, giving up a little on final drive ratio, and using an even thinner support frame to try and achieve a 9 stud width so that it fits within the space that the model requires on the frame.

In the photo above the new build is on the right side. It is one full stud width narrower. Note the single half beam between the tan coloured 12 tooth gears. This is the same gearing principles as the prior builds, but lower gear ratio to permit a tighter transfer box. This worked out better for framing strength. Bracing is added in the middle of the gears to always have a support on each side of the gears even in the middle of the transfer box. The space for the boom is now 6 studs, not the 7 that I had originally built so the boom will require a redesign. I may also reconsider the support structure for this boom drive as it would work better structurally if it more closely mimicked the real Volvo body frame:
