Cheers Ken, I was going to draw some little feet on the tank and burner but got side tracked. I put the valve on the feed pipe so we could swap burners. I drew the feed tank up like that so there was no open fuel except in the burner it self, I'm still trying to think up a way of making the feed...

Hello guys , my apprentice is still on holiday so no actual work done, I've redesigned my boiler and had a think about the burner and tank. I've also had a go at pressing out the boiler end caps. The 3mm copper plate still hasn't arrived yet so I used a bit of 3mm aluminium just as a test...

Sprocket, not used to working in miniature, the theory is basically the same just smaller scale. Steamchick explained about superheaters to me and suggested routing it down the flue to the burner and back again, the bore of the flue is 22.2mm so i had to get a tight bend, the form roller is 16mm...

Cheers Ken all understood. Your idea for routing the heater tube has saved loads of work, one bush in the boiler top instead of the 2 through the flue and the one for the outlet in the top plus I was going to Tig up 2 90 deg elbows Best regards sutty

Hello Ken, you are of course right about boilers, never had anything to do with steam or boilers but it’s an interesting lesson and I'm enjoying it. After spending my working life as a machine tool fitter in all kinds of industries and manufacturing processes, most of the time solving the...

Cheers Ken, more mods to come, better now than when it’s all made up. We can see the logic behind your design. Edd’s away for a couple of weeks now so his brazing tuition is on hold , his technique with the O/A torch seemed pretty fluent, he seemed to understand the temp adjustment between...

Ken, do I need shoulders on the elbows for the superheater where they pass through the flue or will a decent fillet of silver solder suffice ? the elbows will be St/St and TIG welded together and soldered into the flue Edd's took to the torch like duck to water, his first couple of practice...

All knowledge is good to me, especially when it’s free, I feel I should have learnt this 60 yrs ago but two stokes took over. regards sutty

Ken, the type we were looking at doesn’t involve pressure or pumps, it’s shown in K Harri’s book page 99 plate 5.7. We can make it all from stock tube, there would be quite a bit of silver soldering on it, he’ll either get good or bored but all kinds of welding needs lots of practice. keep the...

Cheers Ken, yes and they look good but I want this exercise to be two fold, 1/ to get him interested in engines (all kinds) and 2/ to get him used to the making things bit. I tried to get him some Balsa wood model plane kits, you know the ones I mean, the ones you build on the plans then tissue...

Ken, enormous help, thank you. I've added a couple more bushes to the design, one for a blow down valve and one for a water feed . I've also designed the super heater tube to run down the flue and back again from 6mm St St tube with stainless elbows through the flue. The burners are nearly...

Ken, hope we're not being a pain, here's a modded drawing. The bushes are all phosphor bronze and everything will be silver soldered, we're upgrading the firebox to 10g, there are 8 cross tubes 3/8" 16g the top and bottom boiler caps will be 10g , the flue will still be 1'' x 16g

Cheers Ken , changed the drawing to suit already, I'll post a pic in a bit for your views. Regards sutty

Thanks Jens.

Cheers Ken, and does the glass tube diameter have to be a certain size ? regards sutty

Hello guys, back again. How much water should be in my boiler, I know it’s a bit of a silly question but I meant volume wise in relation to the total capacity and where to site the water level gauge. best regards sutty

Thanks for that Ken, going to Print them off and hang ‘em in the workshop, I’ll start Eddie of on some simple equations. best regards sutty

Ken, ED asked me what the abbreviations stand for, I don’t want to guess or get them wrong, if we’re going to do something we want to do it right, I’m having a hard enough time answering his questions as it is . best regards sutty

Ken, all good by us, it’s interesting to hear the differences plus it’s giving Ed an insight to material choice and design. regards. sutty

Charles, I think you’ve come in half way. We’re not building a loco, we’re building a small stationary mill engine, what you read was a brief history. we know nothing about steam but a lot about engineering and I needed a project to fire up the grandson and bring him from his virtual world of...
