I'm going to post this topic here as pretty much everything I shall be using will be scratch made or etched, the subject is making an upper quadrant signal in O Gauge using mainly scrap brass material and only a few etch items such as signal arm, cast lamp case and weight bar. So this signal once built is going to form part of the Birchall Tunnel diorama which I shall start quite soonand is modeled on Leekbrook Junction's Number 1 Up Distant on the Churnet Valley line, this signal was located 860 yards north of the junction clearing point and was situated on the Leek side of the Birchall Tunnel on the embankment. For the purposes of my scene and to add some interest I shall show the signal in the cutting near the tunnel portal. First job this afternoon was to make a jig to hold the brass tube in place and drill a few holes, the jig is just made from lolly sticks PVA'ed onto a block of hard wood with drill hole points marked in ink, the dot on the sticks denotes where the centre of the lamp lens is. Here was the test piece to see if it worked... some of the holes are out of alignment and this tube was then scrapped once I'd sussed out a good way of working.
