Talltim Posted December 26, 2013 Share Posted December 26, 2013 I've got a 40 degree (or is it 50 degree?) diamond to build from code 83 rail. It's American prototype and mostly consists of castings. Any ideas on how to represent this? http://donsdepot.donrossgroup.net/dr0001/cnw344.jpg Link to post Share on other sites More sharing options...
Michael Woolford Posted December 26, 2013 Share Posted December 26, 2013 Perhaps build the vee and then construct a jig around it which can be filled with solder to represent the casting? Michael Link to post Share on other sites More sharing options...
RMweb Gold beast66606 Posted December 26, 2013 RMweb Gold Share Posted December 26, 2013 We've had an HO one on Widnes for a few years - I can't remember where we got it from now or what the angle is, but I know a man who does. Link to post Share on other sites More sharing options...

Grovenor Posted December 27, 2013 Share Posted December 27, 2013 You buy these: http://www.proto87.c...roduct1903.html Except that they are not on offer for the required angles, but you could talk to Andy Reichert and see if he would add a diamond crossing set to his range, they should be quite popular as such diamonds seem common in US practice.

Talltim Posted December 27, 2013 Author Share Posted December 27, 2013 I had looked at the Proto87 store and came to the conclusion that all the cast crossings were for switches. I think I will ask on the proto 87 e-group Link to post Share on other sites More sharing options...
Talltim Posted June 5, 2014 Author Share Posted June 5, 2014 I've actually started building this, and realised that I don't know how to isolate the check/wing rails. I've got a couple of frog juicers to deal with the frog polarity as per http://www.dccwiki.com/Wiring_Crossings#Frog_Juicers but in an all soldered handbuilt crossing what do you do about the rails that run across the direction the train is traveling? The wing rails at both ends of this cross rail will have the same polarity, but with the possibility that the back of the wheel may touch you would get a short circuit.

Talltim Posted June 5, 2014 Author Share Posted June 5, 2014 Hmm, this photo shows one way http://i67.photobucket.com/albums/h305/Renegade1c/diamond.jpg, but leaves unsightly gaps (not sure why they have cut through the ends of the wing rails). Do people do it this way and and do they fill the gaps with anything? Edit:Think I've found my answer in a nice step by step http://coxy.squarespace.com/coxys-n-scale-and-railroad-bl/2007/3/30/curved-diamond-crossings-for-the-mn-rr-part-6.html. I'm contemplating an alternative, with plastic wing rails and diamond, any thoughts on this? Link to post Share on other sites More sharing options...

The gaps in the ends of the wing rails are completely unnecessary as gaps can be provided a bit further from the crossing in the plain line. You just need the 4 gaps in the centre of the diamond. At that sort of angle the real thing will most likely be made of 4 castings joined in those 4 locations, insulated if it has track circuits.
