... very acurately mark the rails for length then cut them using a piercing saw although I only cut entirely through the rails where electrical gaps are needed using the Exactoscale insulating fishplates as you can see in the pic. Using this approach I have never needed jigs for crossings- most of mine have been to odd angles or been curved in anycase- but do make a simple wooden clamp to hold the rails for filing. (as per the very original Protofour method- available via the Scalefour Soc website) Best regards, Howard. 1129_050750_130000000.jpg 1129_100905_120000000.jpg posted: 5 Dec 2010 13:28 from: roythebus Thanks, that's more or less what I thought.

One thing I do to make sure that crossings and wing rails are perfectly aligned is to leave the rails well over length until the whole assembly is soldered up.
