Moses of the Mail Posted November 22, 2014 Share Posted November 22, 2014 Does any know where I can obtain a list of frog angles for point work in 4mm scale 16.5 mm track Thanks Link to post Share on other sites More sharing options...
Grovenor Posted November 22, 2014 Share Posted November 22, 2014 Frog angles are frog angles, they are completely independent from scale or gauge. If you mean frog angles used by commercial track suppliers then you need to check suppliers websites. Some track designs do not have identified frog angles, they may be based on a specific curved track radius or on the angle of divergence at the end of the turnout rather than at the crossing nose. Most of the Peco points follow one or other of these ideas, only their Code 83 American range has specified frog angles. Regards Keith Link to post Share on other sites More sharing options...
Gordon A Posted November 22, 2014 Share Posted November 22, 2014 You will also need to know what size rail you intend to use i.e. Code 100 or Code 75. To the best of my knowledge C&L are the only UK commercial sellers of pre assembled crossings in 4mm. If you are looking to build your own point work, then it is not too difficult to learn to make your own crossing assemblies using appropriate jigs.

brossard Posted November 22, 2014 Share Posted November 22, 2014 Iain Rice's Finescale Track Construction is a good starting point I think. Another is Traxx 2, book and DVD (I made a code 100 double slip following the instructions). You might also benefit from getting Right Track 10, Laying Terrific Trackwork with Tony Wright and Norman Solomon. John Link to post Share on other sites More sharing options...
Moses of the Mail Posted November 22, 2014 Author Share Posted November 22, 2014 thanks for your comments. I have built turnouts,curved tornouts, diamond crossings. single and double slips using SMP templates, but i need to build a couple of points to 382 and 40" rad using code 75 rail and it would be useful to know the angle of the frog or common crossing for those radii as a datum for the curved stock rail.

garethashenden Posted November 28, 2014 Share Posted November 28, 2014 Could you draw the turnout from that information in Templot and then work out the angle from that? Link to post Share on other sites More sharing options...
