Thanks Rod, that is exactly the way. It takes quite a bit of force to separate them but faint heart never won, etc...

Hornby -ex LMS non corridor coaches

These are Hornby R4689 and R4691. Does anyone know how to separate the body from the underframe? The usual 20 thou styrene between the bodyside and the solebar doesn't seem to work and there appear to be some tabs of glazing material in the extreme corners of the floor which don't respond to gentle ...

Re: Blade filing jig.

These jigs used to be supplied with two machine screws and washers but recent ones have only one screw. I queried this with Jeremy at Scaleforum and he told me that the second one was unnecessary - and he's right. The piece which is screwed on to protect the foot of the rail will also firmly clamp t...

Has anyone tried using the GW Models roller? It would be a bit cheaper than the item suggested.

Re: Best technique for curving rail?

I've had this problem too and find that, with nickel silver rail, I have to be very careful to avoid it happening (when bending I try to apply a bit of downward pressure to the ends as well as the bending force to counteract the tendency for the head to rise). I have put it down to the additional ma...

It does - compare, say, an LMS Duchess with an LNER A1, the former is much more pronounced than the latter.

Re: Drill for rivets.

Getting rivets lined up to pass through the hole is bad enough when drilled 1.1mm, perish the thought of inserting them into a smaller hole.

Re: Track Laying

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...

Re: Track Laying

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...

Re: BR CCT's

………..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...

Re: Bachmann LMS twin conversion.

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.

Re: Turnout construction - Question here please.

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 ...

Re: Flange thickness-effect of.

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...
