an update on my bench.

>i took a look at a 10 kit set for a full cornish riviera express
I look forward to seeing how these build up as I admire your coach building skills.

I have now updated my panel diagram with connection details in preparation for actually wiring it all up. There aren't many spare from the 180 available:-

Beautiful paint and lining jobs as ever Peter

>there was no mahogany paint
You'll be after tartan paint next

That's a fascinating piece of kit Peter!

As I have not (yet) tried to put a chassis together for myself I have had to reread your description of what you did a few times to work out how this jig helped, so do you mind if I give you my version to see if I have understood you correctly?

It looks like the jig has mounts for up to 5 axles.

The W1 is a 4-6-4 so you put three alignment "pins" through three mounts, ie one for each driving axle. The ends of the alignment "pins" are small enough to fit through the holes in the conrods.

Then you adjusted the position of the mounts on the longitudinal axis of the jig using the conrods to fix the positions.

Now you take some alignment pins which have the same diameter as the axles of your loco and extend them at least the width of the chassis plus a few mills.

Next you try to slide the chassis onto these extended pins and find that one of the bearings is in the wrong place.

You remove the misaligned bearing and enlarge the mounting hole.

You place the chassis (minus the misaligned bearing) back on the jig and then slide the bearing back against the frame at which point you solder it in its new position

I'm a bit hazy on what you did next, but I'm guessing that the important work has been done - all the axles are at right angles to the frames and are the same distance apart as the conrods. The only forces acting on the wheel set should be through the conrods.

Am I close?

Thanks for that additional information. I've filed it away for future reference, but first I must finish the track it's going to run on....

QUOTE I am rather fortunate in being relativly young and so i am hopeing to get 50 years use out of it.

I was having that very same thought when I picked up my rip saw which I bought 25 years ago for about £25. Only another 25 years and I'll be happy

David

Nice work Peter

Can anybody explain why the LNWR chose that particular pattern of wheel construction?

David

Lovely paint job Peter

David

That Nelson does look good Peter!

QUOTE I have some liquid lead that i could put in with PVA but i have heard and seen some very bad stories involving this stuff. the bad stories were because it was in a completly enclosed space but i am thinking that it will only be a small ammount in the top of the boiler i think it will be ok.
Any other suggestions? the weight needs to go in the top of the boiler above the motor.

My experience is that the PVA / Lead mixture needs room to expand regardless of whether it is in an enclosed space or not. I have a five plank open wagon which is now a three sided wagon due to the lead expanding and popping the seam. I also have a variety of pot bellied closed Parkside vans.

I haven't come up with a solution to this yet. I know from previous posts that the preferred method is to get solid lead sheets or blocks and beat it into shape with a large hammer. For liquid lead, I am considering making "ingots" of PVA and liquid lead which are smaller than the target space. I think I could make the formers from card which could be stripped away later or just allowed to burst. The trouble is I don't know how much expansion to allow.

Judging by the chunk that came out of the five plank wagon, there does appear to be a limit on how much expansion takes place.

QUOTE I only have 54 evenings left!

I think the sleep deprivation is getting to you.. it's not much more than that many hours...

Don't rush, it's looking good so far....

QUOTE Video footage of the W1!!!!!!!!!!!!!!!!!!!!

Crumbs !

I didn't realise that they called it "Hush hush" because it was totally silent

Are those drivers really 6' 8"? It's the first time I've ever seen such tall wheels made to look so small.

Interesting to note the turntable been started off by hand?

A remarkable piece of film.
