David Andrews Princess Royal – Return Cranks

I have really struggled for motivation this week so haven’t achieved as much as I might have liked.

I decided that the etched return cranks were a little under nourished and 2D so I added a bit of detail.

Drilling out the circular pattern for the return crank

First a turned a spigot on an offcut of rod and soldered the rear etch to it and drilled out the four bolt holes using 90 degrees spacing on my Proxxon mini pillar drill using the dividing head.

Next, I soldered them to a piece of scrap etch from the kit drilled through the holes to transfer them to the other layer and cut around them with a piercing saw. I forgot to take photos of that bit.

Then I made up eight (actually nine) studs from rod and microbore tube filed to a hex head and cut to length.

And finally I assembled all the parts.

Magnified as they are they look a little rough around the edges but it’s not visible at normal viewing distances.
