Re: Hornby Grange Conversion - Any Advice Please

I have one to do, having seen one running superbly on the Newport layout at Scaleforum. I was so impressed I had to have one. I've got the wheels, but haven't done anything else yet.

Re: Tender chassis construction

Unlike loco chassis, tenders are much more difficult to photograph. I basically use Pendlenton's system of fully sprung suspension (MRJ 6), using parallel axles. As I have a lathe, this is quite simple to make, but utilising Exatoscale parallel bearings and axle conversion packs is a way around. The...

Re: Oh for a simple but effective pick-up system

The original MRSG/Studiolith concept (Prototype 18) of carbon plungers would probably have worked, the pale imitations that have followed have consigned plunger pickups to the scrap box.

Re: Oh for a simple but effective pick-up system

Gibson plunger - I would recommend you don't even go there :!: Stick with what you've done already, plungers are non adjustable, seize, create a lot of friction.

Re: Spectacle plates

Hi Mike

Cillit Bang can cause these problems if it's not cleaned off properly, but the poster was asking about cleaning the etches before soldering - removing fingerprints and tarnish.

Cleanliness is very important after soldering, a good wash in Flash is what I usually use.

Something that is used to remove lime scale, clean shower heads, takes tarnish off a treat.

Re: Oh for a simple but effective pick-up system

Looks a bit more workmanlike, you may need some insulation if the pickups get dragged against the frames.

Next time have a go at split axles :!:

Re: Oh for a simple but effective pick-up system

You're using right angle bends instead of round bends, it's bound to fracture across the strip. The concept also creates wipers that are too short. They need to be longer, otherwise they won't "follow" the wheels as they move sideways. This design will also create a lot of friction, which ...

Re: Oh for a simple but effective pick-up system

From the description, I would suggest the copper clad was too small a piece, and the PB strips were too short.

Re: Shunting at through stations

Without working timetables, sectional appendices and dimensioned track plans, this is speculative.

There is an account of shunting at Burghclere in Burghclere Signalman by Kevin Robertson, that was post war, while I think your trackplans are pre 1942 improvements.

Re: Split Axles Shorting Wires

Hi Bob

Good to speak to you at Portsmouth.

I would suggest the EM society shorting strips are my favoured ones.

I didn't get on with the fine wires, and the ones I built I think failed, but it was a long time ago (late 80s), I've used the shorting strips ever since.

Re: Shunting at through stations

It is interesting to speculate what the reasons might be for the practice on a particular line. Perhaps the psychology that after a hard days work a straight run home encouraged good time keeping. Perhaps in some cases a gradient within station limits meant that an engine leaving a train on the thr...

Re: Split Axles Shorting Wires

Agree on pre-tinning the shorting strip. Use a lower temperature solder, not ordinary solder.

One tip I've tried is to file a slot into the back of the tyre, the shorting strip fits into this, then solder in and clean up so forming a smooth back to the wheel.

Re: Axle/hornblock alignment jigs

Another way of building locos is not to use any of these sort of jigs which rely on setting the wheelbase to the coupling rods, have a look at Scalefour News 142 (is it in the archive Keith :?: ), and build your locos the John Brighton way. I've built several now using his methods and it works :P

I've used a fibreglass brush, or lighter fluid/Slaters wheel/rail cleaning fluid on a cotton bud.

WD40 is also an insulator, so no good for cleaning wheels.

So as not to hijack the subject my reply to Dave K put elsewhere. I am not the person to ask regarding wiper pickups, as such things belong to the old days, but it's a good idea to keep them reasonably long so they aren't too stiff. If you can't make them long enough, put a coil in the wire, so incr...

Here is a little tip, I try to put points on the locos so that croc clips can be attached to the locos for wheel cleaning and programming. Seen here is a Bachmann 45XX with croc clips attached. It's a good idea not to use the old holding croc clips against the wheel, it can result in corrupting the ...
