... on the actual rail you will be using. cheers, Martin. posted: 20 Mar 2018 08:47 from: rodney_hills Rob, Back in the early days of the 00-SF yahoo group... https://groups.yahoo.com/neo/groups/00-sf/conversations/messages/1087 Hello, Modern-ish Lima wheels have flanges thin enough to pass through 1mm flangeways. However, the flanges are quite deep and it has been found that if one wants to have Lima wheels operating over chaired bullhead track and pointwork it's best to avoid the exact scale model chairs by C&L and to use instead those with extra clearance to the inner jaw that are produced by Exactoscale (thank you Mr Len Newman!). This Lima-tolerance issue was first reported to this group by member David A. Smith (see message archive). Thank you Dave.

... now get to the next stage Thanks! Julian posted: 20 Jun 2019 12:49 from: Martin Wynne Hi Julian, Thanks for the link. That's a complex station throat with curved slips, irregular diamond-crossings, etc. I strongly, strongly, recommend that you learn to use Templot on something much simpler, before starting on your magnum opus. Otherwise you are likely to get in a frustrating mess. I have made this point many times here. A first question would be for 1967, is this all bullhead, all inclined flat-bottom, or a mix? It won't be vertical FB, because that was introduced only about 1970. cheers, Martin. posted: 20 Jun 2019 12:59 from: Julian Roberts 3591_200757_000000000.png This is roughly what my screen looks like now, and where I don't know what to do next.

... the majority have previously opted for Exactoscale over CL components, I'm not sure where that leaves CL. Hi Derek, Andrew Jukes has made clear that he is interested only in EM and P4, and won't be having anything to do with 00. That leaves C&L with the entire 00 market, and the copper-clad market, and 0 gauge. All of which is an order of magnitude larger than EM/P4. Or at least it used to be, no doubt the arrival of the new Peco 00 bullhead range has changed things a bit. The addition of the Exactoscale range to C&L was a fairly recent development (since Brian Lewis's time), so its removal still leaves C&L where they were before. The big difference from Brian Lewis's time is that in those days the web site worked, and delivery was same-day despatch. cheers, Martin. posted: 6 Aug 2018 19:49 from: Rob Manchester Martin Wynne wrote: That leaves C&L with the entire 00 market, and ...

108. Track Jig
... the spacings for traditional jointed track with timber sleepers for the BR post-nationalization era. The table shows centre-to-centre dimensions, so to create spacers for a jig you need to subtract 10" (the width of a sleeper) from each dimension. Modern concrete-sleepered CWR (long-welded) track differs. Pre-nationalization track also differs for each company and period, although not by much. Pre-grouping track for different companies varies more and generally used shorter rails. Those dimensions for 60ft bullhead rails are the default settings in Templot2, so to create a jig for such bullhead track you can simply print some straight plain track templates. To choose between 24, 25 or 26 sleepers per length, go to the real> plain track options> rail lengths and sleeper spacings... menu item. For flat-bottom track you will need to enter the table dimensions as custom settings. regards, Martin. posted: 16 May 2014 10:08 from: Len Cattley Thanks Martin, I have printed a ...
... "K" crossings are close to 1:8- one just above and one just below. I have worries about there being problems with the "K" crossings because of the curves on both roads of the diamond- 7mm scale radii 5038mm/3763mm. I've had a thought about re-designing it with a switched diamond but is there a drawing of a slip with switched diamonds? I'm having problems trying to work in arrangements to anchor the switches of the diamond yet allow enough length for the rails to flex (bullhead rail) without encroaching on the slip switches. Or if switched diamonds did exist in slips, were the diamond switches relatively short with hinges?

... helpful again here. You don't need expensive jigs to make a crossing vee, you can use the paper template printed from Templot and do most of the work after assembly of the rails. This method results in solid metal at the tip and cleans up any slight alignment error and any stray solder. 2_201959_350000000.gif I have greatly exaggerated the crossing angle for clarity. The rails are shown in cross-section along the rail -- yellow shows the rail head and foot, orange shows the web of the rail. This is for bullhead rail as shown. A is a prepared piece of rail with the end bent to the crossing angle, or slightly less. Allow a little extra on the overall length. File it (or sand it on a sanding disc) down to the web, as at B. This makes the splice rail. C is the same as A, but bent the other way to make the opposite hand. This makes the point rail. File a recess down to the web to receive the splice rail B, as shown ...
... as hinged or flexible switch blades go it really does not make much difference as long as the blades are a reasonable length. At one time I had some short switches, A4( short A3 ?) in an industrial siding which gave me some trouble until I cut them to create a hinge but if you use B or longer blades you will have no trouble. I use hinged blades but that has more to do with the era that I model and maintaining electrical isolation of the frog than it does with blade operation. Bullhead rail tends to be more flexible than flat bottom but if the blade is long enough you will not have a problem with either. I use code 125 bullhead rail in the visible sections and code 148 flat bottom through a longish tunnel and in the fiddle yard. I cannot help you on the side mount issue. I have stayed away from side mounted point motors on purely aesthetic grounds, although I do have a couple in the fiddle yard where they are not visible. These are just temporary until I get around to ...

... many thanks Mike posted: 13 Mar 2016 22:58 from: Jim Guthrie mikewturner wrote: As a matter of interest what radius are you using at the end of your checkrails? Mike, You've just reminded me that I haven't decided what radius to use. In the first turnouts I have made in 1:32 scale, I tried making them a tighter radius than the standard Templot ones but I'm not sure that I've made the radius tight enough. It's also a bit difficult to put a tightish radius on Code 180 bullhead and I suspect that I might need to make some king of press tool to do it in a vice. I've just popped outside to remind myself of what I have done- I store the track on the baseboards outside- plenty of room out there and that's where they are going to finish up in any case. I've basically used a shorter version of the Templot default straight bend but with a larger angle to give the same distance between the rail and the check rail flare end. I've gone back to the drawings ...

... have discovered a serious bug which has remained undetected for 10 years. The CTRL+ Z REA resets don't work properly if the control template contains a custom switch, and don't work at all if the control template contains a custom gauge/scale setting which has not been adopted into the gauge/scale list. However, I'm a little puzzled about what you were trying to do. Resetting to an REA B6 makes no sense for a narrow-gauge turnout. That's the default startup setting for UK-pattern standard-gauge bullhead track. Thanks again for reporting the bug. I will get it fixed. regards, Martin. posted: 11 Apr 2008 04:57 from: jeckardt Martin Wynne wrote: However, I'm a little puzzled about what you were trying to do.

... with equalized timbering as the timbering of the diamond will always be of this type. It should also be bourne in mind that the nose of the crossing of the inner turnout will be in advance of that on the outer road in order to allow for the track spacing to increase entering the curve.

Hi Paul, For REA bullhead turnouts there is some information on the Templot web site at: http://templot.com/prototype_info.php#chairing_info For V-crossings the special chairs are identified Z Y X A B C D etc., the A chair being under the blunt nose of the crossing.

... it*. It is in fact a short length of curve, and a slight twist is introduced in the rail over the length of the curve so that the canted wing rails can lie level. They should be fractionally above the level of the vee nose to allow for the coning angle on the wheels, but that is done by removing metal from the vee top** (3 /16" at the tip, running out in 15"). See the section through the knuckle in this diagram of an REA bullhead crossing: 2_050420_590000000.png On GWR crossings, the knuckle radius matches the crossing angle in feet. So a 1:10 crossing has a 10ft radius at the knuckle, and so on. On REA crossings (diagram above) the knuckle gap is specified instead, and the rail is curved to a knuckle radius accordingly. For a 1:10 crossing, the knuckle gap is 2.5/32" (i.e. the knuckle gap is wider than the normal flangeway gap of 1.3/4 "). Here's a pic showing ...
... " (FP), i.e. the intersection of the track gauge lines, at peg position CTRL-4. The actual vee nose should be blunted back in the prototypical fashion so that it is strong enough to withstand wheel impacts and is properly supported in the "A" chair on the "A" timber. Here's a close-up of a Templot template showing that: blunt_nose.png It's worth printing a duplicate copy of the template so that the position of details obscured by the timbers can be checked during construction. For bullhead track the blunt nose width is 3/4" wide at the tip which scales to 0.44mm (17 thou) at 7mm/ft, so it's quite noticeably blunt and looks so much better than a sharp vee hanging in fresh air between the timbers. (GWR is 11/16" wide, 0.40mm, 16 thou). For 0-MF (31.5mm track gauge) the flangeways are narrow enough to allow for a scale width blunt nose, and still provide full support to the wheels through the V- ...
