Fitting the Barrel Elevating Gears.

Firstly the right hand carriage side was removed from the carriage.

This is a side of the model Armstrong RML carriage.

I turned a disk with a small hole to locate one arm of the dividers at the centre of the trunnion, and positioned the quadrant gear. Then super glued it, and its pinion, into position. Marked the locations. The super glue will be removed later.

Then drilled and reamed the pinion hole.
The location of the barrel fitting was determined after reassembly of the carriage, with the quadrant gear still glued into position. Very tentatively drilled and tapped the holes for the bronze fitting into the barrel. That cap screw will be replaced by a shop made countersunk screw.

The bevel gear case was located through the pinion gear hole, and keeping the control handle shaft level. The case was drilled and bolted into position. The control handle shaft will be replaced by one of smaller diameter, in keeping with the 1:10 scale.

starting to look like the real thing….
That cap screw is temporary.

A couple of days in the workshop working out how to position those parts and drilling, tapping, and reaming. The other cannon will take less time.
