Indomitable026 Posted December 16, 2020 Author Share Posted December 16, 2020 Just thinking this through, instead of the joggle, what if the wire went all the way down and out the bottom end of the tube and then was bent back on its self? Would that have the same effect of preventing the switch rising? I’m sure there’s good reasons for the accepted methods... 1 Link to post Share on other sites More sharing options...

It slides under the adjacent stock rail, so it’s not just preventing the switch from rising, but more importantly from rising above the adjacent stock rail. 1 Link to post Share on other sites More sharing options...

RMweb Premium Mark Forrest Posted December 17, 2020 RMweb Premium Share Posted December 17, 2020 I've found operation of the blades and tie/stretcher bars to be an area that seem to get glossed over in a lot of the books/articles on track construction. Personally I've never bothered doing it that way with three bends. Rightly or wrongly I've previously got away with just an L bend in the wire soldered to the inside of the blade. Think the bar in the turnout operating units on Fryers are at something like 16.5mm centres. I do have an issue with one of the blades occasionally rising up; to date it hasn't caused any running problems, but it doesn't look great. Alternative would be to solder a tab of nickel silver to the underside of the blade that goes under the stock rail, or a pin through the web of the stock rail that aligns with a hole in the blade. 1 1 Link to post Share on other sites More sharing options...

I’ve purposely drawn this subject out because I’ve found the same - a lack of information. Yes I was wondering if to go down the tab route. Thank you for suggesting that.

I did that with the 5 turnouts on my last P4 layout and had no issues with the switch blades lifting or otherwise going where they shouldn't have...

Indomitable026 Posted December 18, 2020 Author Share Posted December 18, 2020 Day off today, so getting a few jobs done on the layout. I’ve had the board down so I took the opportunity to do a couple of under the board jobs. I’ve put a bottom on the wash road pit and also fitted the Tortoise mounting units in position. I’ll touch up the paintwork later. I know it’s under the board and you can’t see it but I like things neat and I know it’s there... 3 1 Link to post Share on other sites More sharing options...
Indomitable026 Posted December 18, 2020 Author Share Posted December 18, 2020 Back the right way up. I’m moving forward with the buffer stops. I’ve re-aligned the sleepers to coincide with buffer stops rails, put the inner rail parts on and chaired up. 8 Link to post Share on other sites More sharing options...

Chairs only on single rail sections and sleeper spacing modified to suit? Or in the case of the style in Damian's photo, no chairs on the triple rail section. 2 2 Link to post Share on other sites More sharing options...

I agree. Found it very frustrating that all the books etc concentrate on rails, sleepers, chairs, gauging but omit the bit that makes it work. 2 Link to post Share on other sites More sharing options...
RMweb Premium Mark Forrest Posted December 19, 2020 RMweb Premium Share Posted December 19, 2020 Nice clear photo of a bufferstop here (although appreciate it is likely to be a different type). It does appear to have chairs on some of the double rail sections, possibly special chairs? I've seen a photo somewhere that looked like it showed a chair with keys on both the inside and outside of the rail. What you really need is a good clear photo of the prototype. 1 Link to post Share on other sites More sharing options...
Indomitable026 Posted December 19, 2020 Author Share Posted December 19, 2020 Ok, I’ll have another go at this - I didn’t realise about the Dave’s website! I mean - how much easier would that have been? here’s a picture of a buffer stop with the triple section chaired. https://www.alamy.com/buffer-stop-and-rusty-sidings-dartmouth-steam-railway-kingswear-south-devon-england-uk-image213294190.html?pv=1&stamp=2&imageid=45293AD2-A8B2-419F-9C4A-E83565C1014D&p=87346&n=0&orientation=0&pn=1&searchtype=0&IsFromSearch=1&srch=foo%3dbar%26st%3d0%26pn%3d1%26ps%3d100%26sortby%3d2%26resultview%3dsortbyPopular%26npgs%3d0%26qt%3dbuffer%20stop%26qt_raw%3dbuffer%20stop%26lic%3d3%26mr%3d0%26pr%3d0%26ot%3d0%26creative%3d%26ag%3d0%26hc%3d0%26pc%3d%26blackwhite%3d%26cutout%3d%26tbar%3d1%26et%3d0x000000000000000000000%26vp%3d0%26loc%3d0%26imgt%3d0%26dtfr%3d%26dtto%3d%26size%3d0xFF%26archive%3d1%26groupid%3d%26pseudoid%3d%26a%3d%26cdid%3d%26cdsrt%3d%26name%3d%26qn%3d%26apalib%3d%26apalic%3d%26lightbox%3d%26gname%3d%26gtype%3d%26xstx%3d0%26simid%3d%26saveQry%3d%26editorial%3d1%26nu%3d%26t%3d%26edoptin%3d%26customgeoip%3d%26cap%3d1%26cbstore%3d1%26vd%3d0%26lb%3d%26fi%3d2%26edrf%3d%26ispremium%3d1%26flip%3d0%26pl%3d 1 Link to post Share on other sites More sharing options...

Indomitable026 Posted December 19, 2020 Author Share Posted December 19, 2020 No more bets please - no more bets. This is what I settled for, a compromise between the Website instructions (4 sleepers on single rail in the middle) and what I photographed at Inverness (2 sleepers on the single rail). 7 Link to post Share on other sites More sharing options...

Further dry brushing weathering will be added later. Looking good, but have you run out of fishplates? You've reminded me that when I assembled some brass bufferstops for Foundry Lane I glued a square of paper between the support brackets and the cross bar. This prevents a short when a wheel (inevitably) bridges the gap between the running rails and the bufferstop. 3 Link to post Share on other sites More sharing options...
