Re: Eileen's split axle test

There is a step missing. The silver steel rods should be heated until they are bright red and dropped into a cup of cold water. This will harden them enough so that when the tube is sawn there is no possibility of cutting into the central rod. Also I would suggest that one gap would be preferable as...

The easiest way of doing 6 wheeled underframes is here, providing, of course, that C&L have the Exoctoscale axles

Re: How real do your photo's look?

Photos of trackwork often show the same bodging and irregularity suggested for buildings. Maybe Templot needs a Jerry-built option? I'm not sure that this is true. There are photos, of pre- grouping track, where the sleepers are parallel but the ends of said sleepers are not square, or of even leng...

Re: profiling EM wheels to P4

My impression is that CLAG contains some very skilled precision engineers. Their view of such matters may perhaps be coloured by their general approach to model-making, with much greater emphasis on dimensional accuracy (particularly in the engineering) than the average model-maker. None of us are ...

Re: Barrow Road Breakdown Train - Identification of stock

The clerestory is/was MR Bain 54' corridor stock. Which one is anyone's guess. These sorts of conversions seem relatively common. The lefthand one is a staff van built by Derby on redundant underframes. See p 431 of Lacey and Dow for a similar one. The middle one is a six wheeled brake with centre l...

Re: profiling EM wheels to P4

All Sharman wheels (including the 'P4' ones) were 2.3 mm wide instead of a scale 1.8 mm. Clearly the width of Mike Sharman's wheels has not been a problem for people working in P4, or we would have heard about it - they were very widely used at one stage, and it is only their non-availability in mo...

Re: profiling EM wheels to P4

I think I would use the Alan Gibson LowMac wheels and ignore the extra half millimetre on the diameter.

Re: Are RTR models 'really' that good?

John's specific point about the seating of domes and chimneys is quite valid; his examples were Bachmann and having looked through the pictures of all the engines I've converted over the years, it is true that the Hornby ones are much better in this regard. We now have technology (and the inclinati...

Re: 0-4-0T csb

I can't see much point in putting a CSB into an 0-4-0T: pitch stability will be more manageable with 4 separate twin-support springs.

CLAG meetings

After a modicum of discussion it was decided that the next CLAG meeting will be on the 16th of November. Thereafter meetings will be on the second Friday of the month. Unless, that is, someone has something really exciting to tell/show us and then extra dates can be arranged. The meetings take place...

Re: Driving wheel axle material

Loctite is not a glue. It is a retainer. Meaning it reacts with steel in the absence of air and expands slightly, making a tighter force fit. It does not react in anyway with plastic.
But apart from that. If a wheel bore is less than the axle diameter just how thick will a glue film be?

Re: Driving wheel axle material

Quite right, Bill, a few microns either way is not the issue. What is of issue is a value a hundred or a thousand times that. Generally, anything 0.1235" or less will be useless IMO. It might suit a tight Sharman wheel bore, but an Ultrascale bore will not grip that sufficiently. And let's rem...

Really??????
Given the way that most frames are designed and built I would think a few micron +- on the axles were the least of people's problems. But then, P4 builders do like their hair shirts.

Re: Driving wheel axle material

I am pleased to hear that you managed to get these materials to work together, Paul. Can I ask, when using the tube and rod from Eileen's, how you cut the tube after assembling it onto the rod? It's best to cut the tube before assembling the axles. Also it is a good idea to make the inner rod sligh...
