Another small crane detail not in the Italeri offering. I am going to call it a "Stop Rest". The purpose of the rest is that it supports the Knuckle arm when it is totally stowed for travel and the hydraulics are turned off.

A few more detail shots of the Groves crane:


Drill holes you might want to add as extra details for your crane build.



Add some extra details to the hydraulic winch.



Lots of hoses run under that main center strut. Might want to add those.



Add small beads as control knobs or use bead headed straight sewing pins to make the control levers. Also add fine plastic rod as hoses to the hydraulic cylinders of the support legs.

FINISHED . . . .

Did my cables and hydraulics "thang" to the Groves crane last night and then a coat of gray primer:
(It's all real this time - no Photoshop.)







Model is still movable. The hoses tend to offer additional resistance to movement allowing the model crane to now better hold a given position.

Thanks Rob, I appreciate it.

Very much did not care for the smallish pivot point provided by the Italeri design of the crane base as it allowed the crane to wobble a lot. Thought a somewhat larger shaft diameter and more solid attachment to the gear ring might make for a more steady connection.




As Doc Brown would say; "I apologize for the crude quality of this drawing and the fact that it is not to scale."

The blue coloring represents glue. I did not make any attempt to build any sort of physical locking retainer for the crane turntable assembly. As of now it just fits very snugly into the base as built on the vehicle and can be lifted out when maintenance is required.

This time I used Plastruct tubing #90604 1/8" and #90605 3/16". These two sizes telescope rather tightly into each other and therefore provide a snug "push to fit" bearing connection for the crane base.
