Re: Bob Moore Lining pens

Advice I read appears to be that lighter fluid is apparently added to, but not mixed into, the paint, the purpose being not to thin it, but to reduce surface tension - the paint should be used neat from a new tin. Cellulose thinners were considered better for cleaning the pen than lighter fluid.

Re: Pentroller repairs

For those looking for an alternative DC hand held controller, the Varipulse from the USA appears to be highly thought of:

Re: The Adventures of an RSU Virgin

I speculate that the solder paste only works reliably if the joint is sweated such that all the flux reacts. I've used solder paste quite successfully with my RSU, but I always add extra liquid flux before applying the iron. While the paste incorporates flux, there doesn't seem to be enough for use...

Re: Weathering rail and chairs separately?

I don't know how much you have to do, but you don't have to use an airbrush - perfectly satisfactory results can be achieved using a small hand paintbrush.

Re: Chassis for a J50

There is also one other possibility, but it is a bit of a cheat. The High Level "tags" to go on the bearings for CSBs have three holes etched in each of them. I think the distance between them is something like 0.75 to 1.0mm (I'm typing this on a Eurostar so can't exactly check my stock)....

I'm not sure how you'll know whether the ride height is correct or not until you've actually tried it, by which time, if it isn't correct. the damage will have been done. I suspect thnat there must be a proper way of working this out and then placing the fulcrum points correctly, and it may involve ...

Indeed it was a 782 class, Julian. Rather crude and I haven't done an awful lot to improve its appearance but it is recognisable as what it purports to be and it runs well and would probably pull all the freight stock that I have (must try that). You're right to be concerned about the ride height wh...

Re: Chassis for a J50

I'd go along with the CSB suggestion. I resurrected a Wills Mackintosh 0-6-0T that I'd part built several decades ago, bought some AG mainframes (hornguides happily already cut out), and used CSBs together with the High Level CSB hornblock system. It runs very nicely indeed.

While challenging the accepted ways is admirable and often worthwhile, ultimately nothing beats actually getting on with it.

And another vote for the Bachrus product. You'll need a set of 50-series "saddles", which are the rolling component (as I don't ever see myself modelling anything with more than three driving axles I got the set of three) and a "stirrup" which basically supports the tender and no...
