Having built several normal turnouts and frogs I finally got the nerve to try my hand at a dual gauge turnout.
Our Phase 7 Extension has several and these have been the mental block in putting track down in this section.
The first step is to build the dual frogs which is the most difficult part of the turnout.
I use rail from a 5 foot section of Aristo SS track. Each rail makes one frog with parts left over for points. I use sectional rail because the rail has 2 holes for attaching each tie section. I cut the rail so that each section of the frog has two holes which I use to screw on a brass plate. This allows me to align the sections of rail.
Next step will be to solder the rail to the brass plate and then trim off the extra brass.
