After the J63 I promised the wife that I would finish the A3. So I set to and cut out the the centre hornguides and soldered in some etched ones from the spares box. I sprung them with some nickel silver wire.
Sadly as I was soldering parts on more parts were dropping off.....
To make it easier to deal with the horn blocks I removed the centre springs, drilled them and the frames and tapped them 10ba so that the springs could be screwed on. While doing this I managed to snap of one of the hangers which I repaired with some 1mm rod.
After my experiences with the plunger pick ups on the J63 I decided to short out the wheels on one side of the loco and one side of the tender to use the american method of pick up.
To this end I had bought some small plugs from eBay and I made a set up, I made a representation of a hose by winding some soft brass wire around a piece of brass rod this rod was then removed and the wire from the plug passed through. Over the outer part I placed some heat shrink tube and shrunk it. This is for the tender pick up. I plan to solder a hook to the bottom of a paxolin drawbar to support it with the plug hidden under the tender chassis.
