Spamcanman Would love to tackle the coal fired version, but not sure yet. I have been studying the boiler plans and it has been designed for coal firing so maybe thats the way I'll go. This would be my first big boiler build so it may take me a while to construct it and then solder it all together, must say though I am looking forward to it now my skills and courage are getting better. Not sure about the cylinders though, don't know if they are still available or if I'll have to make them from solid brass or something like that, cast iron would be better I think. ace
Decided to build a rotating jig to hold the loco whilst working on her. It will adjust to any size G1, just got to fabricate some small 'G' clamps to clamp the frame to the jig, quick lick of paint and there she is. Only took a few hours to make.
No yet yet, Should have pinched yours while you were not watching last weekend. Who did you get yours from - Walsall engineering?. Looked on the stall and noted that they didn't have wheels with weights on in my size, haven't looked on their website though. I will be sizing up the cylinders this weekend with the hope of fabricating my own - don't look to difficult to do (might take me awhile).
Few more hours in the workshop drilling the 26 holes in the main frame stretcher, tricky thing that was to setting it up true in the frame. however the new home made holding jig has made this task that bit easier by holding the main frame in place whilst the stretcher was clamped in place.
Final job done including the 26 holes taped out to 10BA and the stretcher screwed into place and the water pump fitted.
The front pony truck now being offered up and the main frame stretcher fitted into place with the aid of the new jig ;D.
I am about to start work on the boiler and already have a piece of copper tube that will be long enough but it is only 16 s.w.g and the spec's require 18 s.w.g for the thickness will this make the tube I have already unsuitable.
You are right John, I have looked on the internet and can only fing it in 16swg. Same goes for some of the parts I'm making, if I haven't got in stock then I'll make from what evers available to me at the time. I tend to pick-up stock from the ME shows so will be going to Harrogate to stock up for this year. (and lots of other stuff too). ace
Hi Ace, Sorry for not replying I have been away from the PC building a new workshop, I'll take some pictures ASAP.
There is a very good show on over the weekend at The Fosse, Warwickshire a G1MRA track will be on display and Gauge1 loco's running including my Spamcan and 9F amongst others, many trade stands catering for all gauges.
don't use brass - it's considered a no-no in boilers nowadays. I use ordinary phosphor bronze for bushes and fittings, although it can be a pig to work with sometimes. Gunmetal is fine but a bit dearer I think.
I thought you had used the reamed holes earlier to line up your expansion link pivot bush holes in the motion brackets? That's what they are for
