Hi, very interesting and enlightening. I enjoyed reading the thread. Thank you very much.

I'm intrigued by the geometry of what I assume is a lift up section. Could we have a closer look please? Regards John

I'm really pleased to read this. I only came to the hobby during covid, but I've built a few loco's and saw an old Jamieson Jubilee chassis for sale and decided to buy it. A match made in HELL!!! I used 9.5mm spacers from Markits with screw inserts and tested it for being square by putting a 12" length of 1/8 brass rod through the middle axle on my modelling mat. It was absolutely spot on over 11 inches . I put a Mashima motor with high level gearbox in (which runs smoothly and quietly out of the loco with axle and wheels fitted)) and Markits wheels with a Comet motion set. My first rod literally fell on. I couldn't stop grinning!! However, on the other side I had to enlarge the holes and eventually had to do the same on both sides, the holes getting ever larger.. After much bad language I eventually got it to run smoothly at very slow speed but when I accelerated it sounded like a bag of spanners!! To cut this short I then replaced absolutely everything(and I mean everything) and decided not to enlarge the centre hole (Driven) at all, but to elongate the others. Sadly, with the same result. I'm going to take it to the club tomorrow (BELMRC) and hope Messrs Hewitt and Robinson can help. I think I'll have to bush one of the axles. I checked the middle one for square and assumed the outside two would be accurate. I suspect it isn't. I now have much time ,effort and sweat in this and it's fought me very step of the way but I'm not going to be beaten. Cheers John PS. I was "Super D" in my early forum days.

Thank you all very much for your replies. I shall watch the uTube "ultrasonic cleaner" and the Horolene looks interesting. I had also thought of trying dunking them in white vinegar. Anyway, I'll let you know how I get on. Cheers John

I've recently been given a collection of loco and tender kits. They're really well built and I'd guess probably 70's vintage and all are brass/nickel with the occasional bit of white metal. The chassis are old type motors with thick rimmed wheels, so I'd like to put new (Comet) chassis (What's plural for them?) under them, and get them running again. My problem, as you can imagine, is that the brass is now almost black and I'd like to get them clean enough to paint. There are too many to do by rubbing/scrubbing type cleaning and I'm looking for something that I can use as a "bath" type solution. I've used Dettoll to remove paint but not sure if it will do this. I've also tried Coca Cola as I remember cleaning coins with it when I was a youngster, alas. this doesn't seem to work any more. Probably something to do with Safety, 'elf and Welfare. It's quite a collection, with Black 5, Crab, Fairburn, several 0-6-0's and lots of tenders, mostly Fowler with a few Staniers. Just as well, because I've built several 4F's ( I used to be Super D before the crash, but couldn't get it back afterwards, so re registered with this monicker) so any Help / advice/ suggestions would be very much appreciated. Regards John.

Sorry, didn't mean to shout!

HI TONY. I'LL TAKE A COUPLE OF THE MASHIMA 1620 'S PLEASE,

Have you tried Alan Gibson?

I've recently had some vinyl flooring done. There are several offcuts which are ideal for track underlay. 3mm thick, good quality. It occurs to me that it may well be cheaper to do a deal for offcuts with your local flooring shop than to buy cork at todays prices.
