Servo Control of Turnouts
An 00 Turnout fitted with a Servo, which is bolted to a small piece of pcb, which in turn is soldered to a pcb timber. The timber is soldered to the rail via brass rivets.
Normally you could use a small bracket fixed to underneath of the baseboard or glue a plastic plate to the underside of the turnout.
The latter method is what I would normally supply. The pcb method is more costly.
I have removed the first slide chair timber for clarity.
