Re: Loctite and wheels

You might refer to Loctite's documentation to identify the various types. E.g. the page for the 600-series retainers: http://www.loctite.co.uk/retaining-9171.htm . Always worth checking out these things - I've used 601 for years, but only just discovered that it "fluoresces for presence monito...

And in pursuit of some nice model detail, it might pay to think how the prototype was constructed, they wouldn't have soldered the supports to the inside edge of the flue either.


But did they really need to have the roof hinge on the prototype?

Re: Dave Bradwell Springing units

50gm per wagon is a figure plucked from the air via some very dubious north American logic. The NMRA Recommended Practice for car weight is actually 1oz (28gms) plus 1/2oz (14gms) per inch of car length (for HO gauge), so somewhere between 50 to 70 gms would be derived values, without adjustment fo...

Re: Gibson crankpins

The M1 screws you're most likely to encounter will be either coarse, or fine. Fine has a thread pitch of 0.2, coarse 0.25. Sorry I don't know which Colin's crankpins are, or which taps you've got, but there is at least the possibility you've got a mismatch. Have the taps been used much? My 'bush eng...

Looks great in that state, but if you can get such a thickness to dry without shrinking/splitting I'll be fascinated to learn how.

I'd second Mark's comments on the Wills paving, it is a bit of a faff cutting out the bond but it does make a world of difference. This begs the question, though, did Wills ever have any serious intention that the sheets should actually be used ? It would have been easy enough for them to mould in j...

Re: Goings on at the Norfolk Wagonarium

Bearing in mind when two wagons are coupled there's always one coupling hanging 'spare', I wonder how much damage came from rubbing on the 'working' coupling and how much from being clouted by the loose one swinging around? And was there a preference as to which links should be used in such circumst...

You might be able to remove the residual magnetism with a degaussing plate salvaged from an old CRT - bet it runs on mains voltage, though, so might (literally!) be a bit of overkill. More seriously, I have in the past experienced soft-iron coupling links on S&W couplings becoming 'permanently' ...

If a wheel wobbles it will be tight to gauge on one side and loose on the other. Err, isn't that the back-to-back will be tight on one side and loose on the other? It should only affect running if (a) it wobbles enough for the flange to bind/go the wrong side of a check rail, or (b) it wobbles more...

Don't Microsol and Microset fulfil the function of setting transfers / decals? Yes, but on a matt (i.e. rough) surface they can't eliminate silvering (air bubbles under the decal) which is the reason for applying a gloss finish first. Beware, though, that Microsol can react with (Johnson's) Klear t...
