Hi Dan,Pint of Adnams said:[quote=""Dan Randall"":3cx1ljbf](Funnily enough, I need to build a crossover for my S7 test track, so I'd better order some track gauges from the S7 stores soon). There are jigs on the market that make the filing and assembly very easy and given that a ready made vee is about ?12, you'll save a lot of money that would be better spent on a loco kit. :lol:
Be cautious as to the type of track gauge that you buy/use. On the West Mersea layout the roller type gauges have (for obvious manufacturing reasons) perpendicular slots for the rails. In reality and when using the proper chairs a 1 in 20 inwards inclination is required (you know this but not everybody might). The roller type gauges tend to force the rail upright, which springs back when the gauge is removed and immediately results in under-gauge trackwork. The problem is not so obvious or serious in the smaller scales.
I understood that the S7G 'boffins' were considering the re-design of track gauges with a view to improvements, but I haven't heard of any progress. If by any chance you are at the Brightwell-cum-Sotwell event on the 17th April, you could make enquiries. You could also raise the subject with Peter Hunt of Perfect Miniatures, if you had the time to spare...[/quote:3cx1ljbf]
Hi Pint.
Yes, I was aware of the inward inclination of the rails, so given that the chairs take care of that nicely for us, why can't the slots in the gauges be machined wide enough to accommodate the tilted rail, without trying to make it stand upright? Surely the slots would just need to be wide enough that the top inside and bottom outside of the rail were in contact with the vertical sides of the slot, or am I missing something obvious?
Having just given it some thought, maybe it's a throwback to the bad old days when people soldered rails to copper-clad sleepers.... :scratch:
I am intending to visit the S7 bash on the 17th, so if I see someone building some track, I'll talk things over with them.
See you there?
Regards
Dan
