Thank youThat is one outstanding build!
(I think I might have seen some solder in picture 37)
I like to be mean with the solder, makes it last longer!

Sparing with the solder and remove the excess straight away, and obviously solder from behind where possible. I mostly use a microflame torch so with capillary action the solder sucks into the joins and the residue is easy to clean away.

Spent the day going through each section of teh A3 and listing out what needs finishing, the list is fairly long but at least now I know exactly what needs doing so I can progress.
There are a couple items of note which I need some help with.....
Cinder guards on the cab sides, the kit has some pretty poor etched pieces, I recall years ago that someone made some nice cast cinder guards that actually pivot. Does anyone know who made these?
Speedo drive, in later years the class has a speedo drive driven from the rear wheel, this is not part of the kit so again, does anyone know if someone makes some castings for this?
And lastly, what are you guys using for pickups, I had used the Slaters plunger pickups in the past but I recall they were never that successful, any suggestions?
Any help would be much appriciated

I 3D print the top hats now, though I used to turn them, I use 2mm brass rod as the plungers, and Premier coupling springs for the springs, and ESU Hochflexibelkabel (or something rather similar) to wire them up.

I think that you may be thinking of those in the former Hobby Horse range. In their absence I made some pivoting examples for the Princess using the etches in the kit which I modified and added to some lengths of brass angle for the pivot attaching them with a stub of a brass dress makers pin through the hole in the cabside.
As ever these photos will tell much more than my description
This is a cruel close up after painting and glazing

YES! Thats the ones, Hobbyhorse, another supplier that has sadly disappeared, I guess no one has taken over?
Looks like I will have to scratch build something, I too have the etches from the A3 to use as a guide

I've used Alan Gibson plunger pickups on my last couple of 7mm/1ft builds. They work very well for me.
