Chris,
You don’t mention anything to keep the bridle iron vertically located (to keep it and both moving rails from flexing up). I note that Wolfgang didn’t either. Maybe such a thing is not necessary?
(I like the soldered-in spikes idea. That would be pretty similar to the proto:87 frets.)
Thanks,
Jeff.

It's been 30 years since I got out of Hon3, from what I can remember I used a narrow pcb tie with soldered in smallest size spikes for a Bridleiron and normal size spikes for the Headblock. Stops were square brass flats soldered on to the Headblock tie. A DPDT slideswitch was installed underneath the Bridleiron and a vertical 12thou spring steel wire was the throw rod linkage with an offshoot of same to the Harp casting. The DPDT switch was activated horizontally by 1/8 brazing rod to a knob on the Fasciapanel, sometimes these needed an R/C type elbow or crank inserted to line up the DPDT and Fascia.
That was for code55 and code40 rail. My mate bought all my Hon3 stuff and continued with the same tracklaying and turnout operating that I had used, he modelled Gunnison to Montrose with every prototype turnout in between and apart from some heat expansion, mainly in the Pliobond glued-down code40, he had no problems.
