Well that's blown it. The motor I planned to use (pictured above) that I thought was brand new, turned out to be a dud, it runs hot. Checked the brushes and springs which look OK. I've now looked in my spare motor box, a couple of round cans which seem to work, so I'm going to have a look in the EMG...

DJH BR Std.5 chassis built up to "rolling" stage, initially with Pendlenton-type leaf spring arrangement. That was 1991. Bloody spring tails kept dropping out of the adjustable grub screws. No real progress since, especially as new suspension techniques kept on coming up over the years. I...

That is the plan. That is the workbench after I'd tidied up!

I thought they might be, looking at some MRRC gears I have to reduce the speed. It is a goods engine I'm building.

And look what I've found! A possible gearbox for the loco. Motor in the tender. I don't know how long I've had these gearboxes - weren't they part of Dynadrive (some of that pre-DCC nonsense to get better response). Anyway, they appear to work and I've got two of them. Just coupled them up to the mo...

Well, with broad gauge stuff, my working area went down to about three inches square - something had to be done, so I'm tidying the bench.

Can I just thank all the posters on here for helping to keep my spirits up during this crisis. It feels good to know there's a brother/sisterhood out there going through the same as me and finding some positives in a dreadful situation. Keep well. Andy Well said Andy, I too am finding it difficult ...

Tender body assembled, minor problem as it appears the castings may be slightly over-width, but a bit of squeezing and fiddling looks like it might be on track. Motor tried in position, next is to make the running gear.

Too late - already made them!

As said, I'm building this without recourse to any outside trade help. So although the BGS may have the correct wheels (for example), as I'm not a member I can't use their excellent trade counter!

Decided instead to build the tender first. Axles being made, wheels sourced.

It wasn't me M'lud.

Well that just slipped out! It was supposed to say round pin 15A!
I don't believe it - a website dedicated to old plugs - and the plug I was referring to!

Ah shows in the 70s. You never knew what socket you would get at the venue, round pin 5A, round pin 13A, 2/3 pins, used to have to take a supply of extra plugs. Then I found a converter plug - it had all options (I wonder what happened to it?). You just popped out the appropriate pins, screwed them ...

It was a very complicated box with spring strips - I used to have the instruction booklet, but looks like that's gone. The castings weren't bad, but the valve gear was very good.

Starting work on the BG goods engine, first job is make the split axles. Very few useful dimensions on the BG website, but I've calculated that a 45mm axle will cover the outside framed engine. So I've started making them.

Right, in my kit mountain I've found a Sharman kit for a Hercules class 0-6-0 broad gauge engine. I've found some used 5' diameter wheels. I've found some hornblocks. There could be a good motor (untested as yet). Some gears. The plan is to do it without recourse to ordering things in. Basic spec sa...

You asked the question, I expect a full report back (and an article for the snooze).

Concerning springing to improve electrical contact, it's worth noting that this is now common practice in 2FS, where spring for track holding don't work much and aren't considered necessary. The 'springs' are actually bearing on top of the axles (split frames), there is usually minimal slop in the ...

Actually, there is quite a lot of slop in RTR mechanisms. And that slop isn't just for road-holding, but for pickup. I can't recommend building rigid chassis with 'slop'. If you are going to that extent, putting in a simple beam system (remember that?) isn't much more work and will result in a far b...

Oh well, as for diesels, I had a Bachman warship that ran beautifully with new wheels, a Helkan Hymek that, after a change of motor runs superbly.
