Hi

I'm contemplating starting a long term project:- a 2-6-0 Horwich Crab to Don Young's design.

Is there any one out their with any information or experiences of this design, what are the pitfalls, drawing errors, general impression, where did you get the casting/boiler/laser cut parts from, how did you deviate from Don's design etc etc.

Cheers

Stew

I realy don't find loading pictures to this site user friendly this should be at the beginning of the sequence:-

and they've gone out of sequence.

 

Ho-well you'll get the idea.

Excellent Stew,

If it wasn't for the time on each pic, I would assume you have a putting on tool.

I've made a fair bit of progress with the crab so I though it was about time for an update.

I've got the frame assembled with the stretchers and the horn blocks machined, sorry no photos I can't find them.

I'll take a picture of the stuff assembled in the frame

I'm currently working on the pony truck this is fabricated from laser cut parts, I'm scratching my head with how it goes together especially the spring centring I'm not following the drawing I'm trying to use my own idea to simplify the arrangement.

Time for another update

This is the progress so fardsc02931.jpg

The pony truck was fabricated and silver soldered together

I didn't follow Don young's centralising system I used a simpler system copied from a friends 7 1/4 crab, I'm taking her to the club track next week to push her round the bends to check that it works OK in 5".

This is a picture of it.

Its a getting a hefty lump to handle so next week I'm going to make/modify an assembly jig so that I can move her about without giving myself an injury.
