I'm following Stew and I agree with Bill  :ThumbsUp: :ThumbsUp:. I think with that big of a lump spinning in the chuck I'd be drawn up tighter than a bull in fly season  :ThumbsUp: :ThumbsUp:

No. Your spelling is too good. Or is that what the rum does for you?  ;D

Stew

I have had great success with making the bobbin from stainless but fitted with the working bits made like a pair of polo mints these were made of PEEK ( login end sell it by the inch its expensive) this way if there is a problem then you only need to make a new polo mint

PM with your Email and i will draw it up in  fusion 360 i can produce a PDF from that if you do not have it

Kirk and Stew - Thanks for the reply  :)

I didn't think of a inspection hole the valve - but it makes quite good sense to be able to inspect function and timing through it - should have looked a bit more on the first picture (it's very small picture on my PC) :ThumbsUp:

I did not spot the draincok (sp?) holes, but I expect that most of the threaded holes on the side are for mounting on the frame and some are for the steam in and out.

The reason for my question about the smaller hole, was the simple fact that I hadn't seen a full size valve on a model before  :old:

The part that goes between the cylinders is the saddle, which also supports the smokebox.  Given the holes in the cylinder, I expect that the saddle is a two piece casting/fabrication.

Well its been a busy summer I've been beavering away on this project as well as running my Simplex Loco I recon I've clocked up about 250 miles on it, any way I thinks I'm well over due for giving you guys an up date, I'll probably spread it over a couple of post as I've made a fair bit of progress.

That's it for now I'm getting really p****d off with the performance of photobucket/ internet connecting /lap top:- I'll try again this evening when there is not so much traffic.

I've got the frame built and the cylinders mounted I'll show pictures of this in the next instalment.

Stew mentions the use PEEK earlier in the thread (and I presume he meant Noggin end as a supplier).

Very nice work and it will make a handsome engine (in an ugly/beautiful sort of way  :???:)

That is some nice progress and some fine looking parts there Stew. Looking forward to seeing the cylinders attached to the frames.

That's correct the spools are made from PEEK plastic I was given the idea on another forum apparently its very good in that application, I know of another chap whose used it for piston rings in his engine.

I've found out that the only Horwich Crab in preservation will be steaming at the Severn Valley Railway on 6 to 8th November so I'm going to take a visit.

Impressive amount of precision work in these cylinders and valves, wow...
is it easier to do the guide bar bracket as a separated piece or included in the rear cover ?

Stew,

I don't know if these are useful to you, but here are 3 pics I took of the Crab in the National Railway Museum in York this spring.  Currently she is set up heading a rake of carriages on a platform so you can't really see the motion terribly well.







PM me if you would like some higher res copies.

Cheers,

Rod
