Hi Dave, Welcome back. The whole of Old RMweb is still available. Your Heatherburn layout topic is here: http://www.rmweb.co.uk/forum/viewtopic.php?f=9&t=34851 Your Potters Lane layout topic is here: http://www.rmweb.co.uk/forum/viewtopic.php?f=9&t=39651 regards, Martin.

Hi Dan, Brian Lewis bought this in as a clearance line, see: http://groups.yahoo.com/group/finescale/message/625 He is open to negotiations for larger quantities, see: http://groups.yahoo.com/group/finescale/message/627 Note that it is 12% Nickel, "yellow" Nickel-Silver. His normal rail product is "Hi-Ni" 18% Nickel, "white" Nickel-Silver. This looks much more like steel rail, and doesn't tarnish or need cleaning. regards, Martin.

Hi Gordon, Sorry if I wasn't clear. No gauge widening is ever needed for 16.5mm gauge in normal conditions -- i.e. standard 00 back-to-back: 14.4mm/14.5mm, and sensible curves, say 18" minimum radius. Some gauge widening on sharp curves may be needed for other 00 conditions -- i.e. using 14.8mm back-to-back (DOGA-Fine), or 16.2mm track gauge (00-SF). (Except for DOGA-Fine) you can regard 16.5mm gauge as already including gauge-widening for sharp curves, and that 00-SF removes it where it isn't needed on straight track and gentle curves. I made a longish post about the 00 gauge standards recently, at: http://www.rmweb.co....post__p__137494 YES. The check gauge dimension you want is 15.2mm min, and it is exactly the same in 00-SF, because 00-SF uses the same unmodified 00 wheels. This means that the 00-SF check gauge tool is the one you want: v = vee w = wing rail c = check rail r= running rail My reference to the EMGS and Scalefour societies was merely to illustrate that the more "technical" modellers don't use combined roller gauges. regards, Martin.

Hi Dan, I don't want to hijack Gordon's layout topic with technical discussions, but there are very good reasons for using a separate check gauge tool and crossing flangeway gauge, rather than a single combined gauge tool. If wing rail and check rail slots are combined in a single 4-slot roller gauge, then: 1. It's impossible to construct V-crossings on sharp curves with gauge-widening. 2. It confuses the setting of the V-crossing flangeway with the check gauge. These are two completely independent settings and shouldn't be mixed up. The flangeway gap dimension at the check rail is the instantaneous difference between the check gauge and the track gauge at that location. It's not necessarily the same as the V-crossing flangeway gap at the wing rail. And it's not necessarily the same for every V-crossing, i.e. if there is any gauge-widening. 3. If there is a problem with the track, it is impossible to see which rail is in error, using a combined multi-slot gauge tool. The rules are: a. Use a track gauge tool to set the running rails. This can be a roller gauge with two slots, or a triangular 3-point gauge to introduce automatic gauge-widening. b. Use a check gauge tool to set the check rails. This is usually a two-slot roller gauge, with a flat-portion for gauging from the nose of the vee. This dimension is the most important in constructing track. You could just about get away with constructing the other rails by eye from the template, but not the check rails. c. Use a crossing flangeway gauge to set the V-crossing flangeway gap between the vee and the wing rails. This is usually a small flat piece of metal of the required thickness, usually sourced from precision shim or a feeler gauge or similar. Under no circumstances should this be used to set the check rails -- use the check gauge tool as in b. above. The EMGS and Scalefour and other societies supply sets of the 3 gauge tools as above, so that the above rules can be followed. They don't supply combined roller gauges. The plain track 00-SF roller gauge tools which were available from the late Russ Simpson in the USA will soon be replaced with a similar tool sourced in the UK. Brian Tulley can update you on the current position, see: http://groups.yahoo.com/group/00-SF/message/966 http://groups.yahoo.com/group/00-SF/message/961 In the meantime, the available 00-SF 3-point gauge tools can be used as an alternative to the roller gauges. regards, Martin

Clue time. There's more than one tree here. But don't get an arrow in your eye while looking for them.

Clue time. This railway adopted an early design of articulated locomotive. Without much success.
