Hi All

Model engineer issue 4576 has part one of a project by Martin Gearing on a vertical boiler for beginners.

Can anyone tell me if this is continued in issue 4577? I've searched online for information but am unable to find anything.

Called in W.H. Smith at the weekend but they had sold out.

I will order a copy online but only if part two of the boiler project is featured.

cheers geoff

Part 2 is in 4578

 

Anyone know if this is going to be a duplicate of the EiM vertical steam plant?

Thanks Frances, Jason.

4578 is out on Friday, so not long to wait.

Perhaps I've missed something but I have to admit to being a bit perplexed by this series. Why would a beginner be encouraged to equip themselevs with a milling machine (not necessarily a small investment) in order to build a simple boiler? I can't recall this ever being proposed in the past sixty odd year that I've been reading M.E. and I've never needed one for that purpose. If you want to encourage beginners wouldn't it be better to show them how to achieve results at least cost, to start with?

I have to say that the use of milling machine puzzled me. That's not a criticism just an observation and I look forward to part 2 in issue 4578. As I have no milling machine I will have to improvise.

I assume the use of a rotary table is for setting out the hole positions in the top flange plate?

In due course all will be revealed.

Looks very much like the same boiler Jason.

Have you got the eim issue numbers? I may need them

I have just bought today M.E. 4578 today eagerly anticipating part 2 of the M.E. boiler article.

I can't believe what I'm reading, preparing blanks and datum locations, understanding working drawings, axis conventions and locations and checking a machine head and vice alignment.

Absolutely nothing to make and it looks very much like part 3 will have nothing to make as well. In part 3, quote, we will look at the bill of materials you will need.

Three parts, well two at least and nothing to make? Do me a favour!!!

Rant over

I think you have completely misunderstood the focus and reasoning behind this series. As I read it the articles are more a "school / apprentice type project" than "amateur builds a simple boiler project".

The author appears to be using the boiler build as a vehicle for explaining many of the skills and concepts a neophyte needs to get to grips with if they are to make successful working models from drawings with minimal frustration along the way. A boiler is an interesting choice for this sort of thing. Usually small tools, work holding and marking out equipment tend to be the subjects. A good example of the conventional approach being the SouthBend book no 39B "Machine Shop Course for Apprentices".

Given the modern trend towards CNC, the greater emphasis on CAD and general tendency towards more complex models using a boiler may well be a better approach here and now. I suspect much, if not all, of the generally applicable learning value could be got armchair wise by careful reading and re-reading. When it comes to marking out, dimensioning reading drawings et al boiler components provide a very clear subject. Probably only the specific constructional skills and techniques need the actual practice of making a real boiler. The old style way is much more geared to learning by doing with considerable scope for just winging it.

Nowt wrong with just winging it. I learned near enough everything that way. But overall its a slow way of going about things.

Plenty of complaints about the old school way books too. "I don't need to make these tools. If I want them I'll buy them for thruppence three farthin' (plus postage) on line. I need useful things to get going on my 7 1/2" gauge Big Boy project."  But then it was ever thus. Think of the guys who bought a cheap Machine Mart welder expecting to fix their rusty MoT failed car just-like-that.

Clive.

Sorry Geoff but I don't usually take EiM, does look like it could be quite a while until steams upsad

I think I read somewhere that the pump will be detailed and made first and then presumably the boiler.

As has been said, it looks like everything on there could be made on the lathe and possibly not even a vertical slide needed so with the series Lathes & More in ME and Neil's in MEW that would have covered the theory so this could have got straight down to putting things into practice.

Maybe Martin could comment on the order and length of the vertical Boiler Articles?

The series in EIM is by the same author and started in Oct.'16 and is still going. It started with a similar preamble then detailed the making of the engine, which finished in Nov. '17. The latest serial (part 11 Dec. '17) details the displacement lubricator. He hasn't got to the boiler yet.

Further to my last, to quote from part one of the EIM series " The project is divided into six parts #1, Engine, #2 Displacement Lubricator, #3, Hand Pump, #4, Boiler, #5, Boiler fittings, and #6, Gas Burner."

Hi Gents,

Thank you a for your replies.

Clive as you say I may have misunderstood the reasoning on this project although the introduction states, quote,

" A project aimed at beginners wishing to develop there skills OR those requiring a requiring a robust vertical boiler for the running or testing of small steam engines."

I suppose it all depends how you interpret that introduction. I saw it as for complete beginners and also amateurs who just want a boiler. I'm just an amateur who wants a boiler so I see myself in the latter category.

My gut feeling is that the remaining articles will be heavily biased towards the complete beginner with a lot of instructional preamble which is not for me.

I'll keep an eye on the progress, I'm in no hurry. I'll just cherry pick the parts of value to me.

thanks again geoff

Hello.

The I have received the first part of this series but ask if anyone who has received the following copies can list the materials required for the drawn tubes and the firetubes, number, lengths, dia and gauge.

It would be good to assemble these parts before receiving the boiler construction issues later.

Thank you.

As welll as the following tubes you wil need a piece of 16swg C106 copper sheet 4" x 12"

Guess if I order and have the material parts shipped by sea to New Zealand the construction issues might be to hand.sarcastic

No really ..just being sarcastic chaps and thanks for the list Jason. I am sure amongst friends we could scrap together the materials and give it a go. Maybe I should start on the boat first.I quite like stationary boilers and the other half seems at ease now with the 8" dia one sitting in the living room. I'll squeek a few more in when she is away.

Thanks.

What is the intended heat source - curious as to why there are so many holes around the base - cant be coal and the holes would be very counter productive to gas?

Gas

As you say any air needed for combustion would be drawn in as part of the burner in most cases so not sure what the holes are for.

LOL!

I put holes in my boiler stand, I even went as far as making a punch from silver steel just for the job. Never occurred to me that they might not be doing anything... I suppose they make it less exciting to light than putting a lighter to the top of the chimney

I find the materials list interesting.

I know very little about boiler design and cannot visualise the internal layout of this boiler from the list.

Can anyone explain to me what the arrangement is LIKELY to be inside the 3" diameter shell.

I've been looking at the 3" Tubal Cain vertical boiler in M.E. feb/april 1977 and it would appear from the materials list that the internal structure of the current M.E. Boiler is completely different. The Tubal Cain design has conical firebox with 3 crossing and angled fire tubes.

Issue numbers 3555 to 3558 over a period of 6 weeks cover the whole design with detailed and informative diagrams and building notes all aimed at the beginner to boiler making making their first boiler.

I think it will have a flanged plate at the bottom and a second flanged plate about 1" down from the top. one ring of 5/16" tubes running vertically and an outer ring of 7/16" tubes running vertically. Heat will pass up through the firetubes into the space at the top and then out up the chimney. Don't think this is a centre flue boiler like the TC one.
