Quote from: trkilliman on June 25, 2026, 08:20:28 PMA friend has moved up to O gauge due to his eyesight not so good as it was.
He has given me a whitemetal kit and chassis as in the subject title.

I have made up the body and cleaned up the gunk that was around the chassis cogs.

I'll look to buy a Tramfabriek replacement motor for it if it's not too large for the 13xx body?. Has anyone done this?

I'd be grateful for any advice, such as any problems encountered and how to solve them.

Thanks
Steve

yes--ive done one, it was my first attempt at a coreless conversion. Unfortunately i got it wrong--the position of the worm wasnt quite right . THe result is it runs beautifully forwards--but reverse means the loco body lifts up leans over and frog hops along.

Hi,
When you say I've done one, was this with a repacement motor to accomodate/fit within the 13xx white-metal body?

I have sent a message to Tramfabriek asking which of their motors will be best suited/fit to the 13xx body.

The 13xx cab area that the motor will sit in is a tad smaller than the original Minitrix cab.

Their website which has good photos of fitting replament motors, just shows a replacment motor for the Minitrix tank loco.

I await their reply.

Top work sir.
Nice layout too.

I agree she's certainly capable but it seemed boastful thrashing rather than a connect to the music.
I like many tracks by Rush but can't take them for more than about an hour

I can see why she might have been a good fit with Jeff Beck: he too was more mechanic than artist in my humble opinion!
(I bet that'll be contentious!)

Well done, Ian. I suspected that it'd be an easy fix as the UM wiring is very basic.

With two traction tyres and the weight of the tender it should cope with Scott's gradient without much trouble, the haulage capability of UM models is outstanding.

Quote from: icairns on June 28, 2026, 11:17:32 PMHere are a couple of quick YouTube links showing Scott's UM Prince of Wales Class No. 5604 "Enchantress" in operation on Ferryhill. 

Apologies for the quality of the videos but I just wanted to quickly demonstrate forward, reverse, slow running, and haulage capacity. 

As I do not have any LMS coaching stock, I paired No. 5604 with a rake of seven Graham Farish "Blood and Custards."  I think the train looks rather splendid! 

I will be mailing the loco back to Scott in Texas this week.  I hope he is pleased with the result.

Can't wait!!

Well done, Ian! I'm sure he will be over the moon.

Scott's Union Mills Prince of Wales model recently arrived at the repair shops here in California.  I have to say, it is a wonderful model and the crimson livery is excellent and very striking.


When I opened the box the coupling from the rear of the tender was loose in the box along with what looks like part of a standard Graham Farish coupling spring that had been compressed out of shape and was no longer usable.  Also, the area near the top of the handrails on the front of the tender on both sides had small paint chips. 

Carefully putting the coupling aside for later. I unscrewed the rear keeper plate screw from the loco to disconnect the drawbar and the motor wire. 

I undid the keeper plate screw from the front of the tender to release the chassis from the tender body and then replaced the drawbar screw and held it in place temporarily with a small nut from my spares box. 

Then I got a surprise! 

This is what I was expecting to see when I took the tender top off.  I copied the photo from the post linked below: 

https://www.ngaugeforum.co.uk/SMFN/index.php?msg=884867


But this is what I actually saw.  Can you see the difference?  From a previous post on this thread, I did think that something had been changed but I did not know exactly what.


Well, the two photos are very different in one important point!  The blue wire was now soldered to both the tender pickup motor terminal and the loco pickup motor terminal.

Surely, it couldn't be this easy?  As long as the soldered joints were good, and the motor had not been damaged in the previous work, all I had to do was cut the blue wire. So, I did cut the blue wire, connected 12V DC to the loco pickup wire and the tender pickups, and the motor ran as sweet as a nut. 

The soldered connections to the motor terminals appeared to be strong so I then cut the ends of the blue wire off as neatly as I could and the completed repair is shown in the photo below. 


To be honest, I was quite glad to be able to put my book Soldering for Dummies back on the bookshelf as I had not exactly shared with Scott that my soldering skills might be described as rudimentary (they have actually been called worse).  But I was confident that I could repair a Union Mills loco, even if I needed to solder wires to the motor terminals as I have done similar repairs to a couple of UM locos before. 

Because the wiring modification was so simple, repairing the coupling on the rear of the tender actually took me longer because it was so fiddly.  The UM coupling pocket is very short so I had to cut down a Graham Farish coupling spring to about one third of its normal length to enable it, and the coupling, to fit into the pocket. It is not a good design. 

After reassembling everything, I then cleaned the tender pickup wheels and gave it a good test run on Ferryhill.  It runs very smoothly in both directions, drawing about 75mA, albeit a little noisily compared to more modern steam loco models (but typical of Union Mills' locos).  The two traction tyres on the tender looked to be in good condition. 

I know Scott has a 4% grade somewhere on his layout but I was not able to test this on my layout as Ferryhill is a founding member of the Flat Earth Society. 

I will post some videos in my next post.

I get the same feeling. Although I have heard very little of her work so far, it seems one volume only. Good mechanics, not too much artistry.

For the AC thing, is there concern that the power infrastructure would need to be updated to handle the load?

Quote from: Moonglum on June 28, 2026, 01:13:12 PMThe UK government is not keen on domestic AC from what I gather @scottmitchell74

This has changed over the years with the arrival of what we call air/air heatpumps (ie aircon with heating ability) or the folks down under rather more sensibly just call "reversible aircon". Today you don't need planning for an air/air system on most houses, you get VAT off it just like solar and batteries and the more annoying regulations only kick in at 12kW of cooling power, which for a UK house and even this current climate is a ludicrous number (but in some parts of the world would indeed be considered as 'toy'). Fixed aircon is now on about 4-5% of UK homes depending how you count, and another 6% or so owned a portable one as of late last year so that'll have gone up a load

Meanwhile I am listening to a rather lovely cover
