Hi Eddie,

Many thanks for the data. I am hoping to join a club - few and far between now in the West of Scotland.

Hi Julian,

I'm only getting the materials together for the boiler at the moment and studying it's construction. Hopefully I will find a club to join long before I build it. The chassis work is keeping me pretty busy at the present.

I thought the Clarkson design a bit odd with its choice of staying when comparing so many other round top boiler/firebox designs in the same gauge by others.

Hi Geoff,

Thanks for the reply. I'm amazed at the variations from different designs. My 3 1/2 gauge Jinty (LBSC Molly) was a lot simpler!

As regards a tester - I have n't joined a club yet - not much going on in the West of Scotland methinks as regards loco building. I hope I'm wrong on that one as there used (20 years plus back) to be a fair amount of loco works and running tracks of which there were three within a fifteen mile radius of where I live.

The 'Schools' was started over twenty years ago and now fully retired just picked up again.

Hi Eddie,

Working pressure is 80 psi and was planning to use copper for the stays.

I found another variation this evening - Martin Evans suggests 4 BA at 7/8th pitch for 13 swg wrappers in his book - 'The Model Steam Locomotive'.

I am building an 3.5" gauge 'Schools' - I have drawings from Clarksons of York dated 1935 by H P Jackson and LBSC Roedean from Mechanics dated 1948.

For the firebox stays in Jackson's design he calls up 13 off 3/16th x 40 tpi per side at 1 and 1/16 th centres. The LBSC design calls up 50 off 5 BA stays on 5/8th centres per side. In both cases the firbox wrapper is 13 gauge.

Which is the better design and recommended staying?

Hi,

Is the annealed copper tube sold rolled up in coils for microbore heating suitable as firetube material or is it too soft? I have always used harddrawn previously on small boilers and there seems to be a cost advantage with the microbore heating tubing. The size I am looking at is 10mm OD 20 swg
