When you mention you can file to make the rails fit, what do you file? Do both rails move forward or just one? |

First, both rails move. If there is a hitch, I can file the diverging rail's outside surface just a bit to get it to line up with the other rail-see sk. I did a couple more turnouts this weekend, this time using code 83 vs code 70, and I found by sliding the 'movable ' piece all the way towards the point portion of the turnout, it worked fine without needing to file anything. Is this confusing? Stephen

I see now. You are building prototypical asymmetric frog point rails vs. the the equal angled symmetrical ones. The point filing blocks from Fast Tracks are setup for the symmetrical assembly. (Though the double slip filing blocks have an extra positioning for the oblique center frog that works well for doing the asymmetrical styles). Likely the code 83 gave just enough extra 'heft' in the profile to allow your filing to make a cleaner fit. P. S. Prototype would have the main route be the solid point rail. When filing the asymmetric diverging route, you have to also (JUST) file along the base of the main route point back a bit further so the diverging point nestles up and fits to the main point. You also have to use a different angle block to make the filing. I use #4 for #8 turnouts, #5 for #10 - etc. Have to 'hand' file the #5, #6, #7 and #9 turnouts after first filing with the #4 or #5 filing block. After a few times, it becomes second nature. Once you fit and solder though, seldom can you actually see the difference in a joint. I'm not sure one gains a lot, though with very light soldering the joint does show (and gives the prototypical cosmetic). |
