When I did organic chemistry at school in 1960-62, methyl ethyl ketone (MEK) was the nomenclature. Subsequently systematic naming of organic compounds was adopted which gave us butanone, or more correctly butan-2-one (not 2-butanone unless that's a recent change). Butan-2-one indicates that the keto...
The original query referred to both wooden and plastic sleepers. I fully concur with the advice given about wooden sleepering, ie use plenty of butanone but the opposite is the case if using plastic (abs) sleepers. Here the need is to use the smallest amount of butanone which will do the job. The re...
………..or maybe not. I can't speak for CCTs but the colour of ends on some -ex LMS vehicles well into the BR period could depend upon which works did the painting, an example being pull and push driving trailer ends which could be red (Derby??) or black (Wolverton??). Finding a photograph of the end o...

I've no experience of the Branchlines P4 wheels but when I did the same EM conversion a few years ago I found that assembling the wheels onto the gear/muff gave a BB dimension which was 0.5mm greater than it should have been. I was told by Brian at Branchlines that these were intended originally for...
Also meths (the violet coloured variety) which, besides being a very gentle solvent, also contains pyridine. I was told many years ago by an adhesives researcher that pyridine acts as a catalyst for the polymerisation (ie setting) of cyano.

When I use my filing jig for soldering I find that the two rails don't quite line up in the vertical plane (presumably the grooves are very slightly out and this is magnified by the rails hanging off the end of the jig) - I then have to apply a slight twisting downward pressure on the jig against a ...

A couple of quick points: 1 RP25-100 exists only in Romford/Markits - it is not listed in the NMRA table which Julian quotes. It is, in fact, RP25-110 with a wheel thickness of 0.100". It only works satisfactorily on EM trackwork because the root radius of the Romford/Markits flange is less tha...
