So I was considering the idea of doing a miniature traction engine of some sort. Because that’s just how I roll.
It looks to me like there are two ways to build your own engine: buy a machined kit (Maxitrak or Steam Traction World) which are lovely and expensive. Or buy a set of castings, and machine them yourself (such as the Clayton wagon or Atkinson wagon from A J Reeves), which is less expensive, but requires to tools and skills to machine them out properly.
While I’m usually a jump-in-the-deep-end kind of person, it is probably sensible for me to consider my machining experience (zero) and skill before I go down the less expensive route. So my options are: try and find a machining course near me, which appears to be very tricky, Gloucester College and Worcester College don’t appear to do anything suitable, but I may just be looking in the wrong place. Or get a simpler first project, such as one of the more basic, stationary engines, from A J Reeves.
What advice do the friendly people on this forum have for me on this topic?

Welcome to this Forum, someone more knowledgeable may come along soon but these people might be able to help.
You could try **LINK**.
They are almost bound to be rail enthusiasts but there may be some traction engine fans and either way, they will know if there are any courses or they may even have their own workshop.
As a previous builder of the Clayton Wagon, I can confirm that it is a good one to build and runs very well. You can always start on easy parts and work your skill level up to the more complicated items.
All the best with it,

Myfordboy does a beginners stationary and also a traction engine. He sells the castings at what I regard very reasonable prices too. I have not built one yet but have watched all the videos and I am thinking of doing the stationary engine.
No connection, just impressed by his videos.

Welcome to the forum. You will probably find that equipping a workshop costs most of the money you save - but it will leave you with a great deal of satisfaction and the means to do a lot more and maintain your engine.
Do expect a self build to take long time.
Most people prefer to start on a simpler subject or two to learn some skills without making expensive castings into scrap... but there are people who have started on the easy bits like Brian suggests - a big, complex model is best considered as many small models - the trick being they have to fit together properly!
The other hazard is getting half way and deciding your early stuff wan't up the scratch, ending up in a cycle of constant improvement and never reaching the end.
Another route is to buy second hand or part-finished and develop you skills bringing it up to scratch.
Just make sure you don't end up buying a second hand boiler without proper paperwork that you can't insure.

First engine i made was John Hainings Suffolk Dredging tractor in 3” scale. I chose this as it is mainly made from standard bright bars sizes and generally fairly easy machining. I did most of it at Penistone grammar school on a evening class over two years. By eck that brings back memories 🙄

The myfordboy blog looks very useful and interesting! I may start there, as it looks like it gives all the support I could want in videos! But I think you're right about the cost of a workshop being enough to put me off. As for a constant cycle of "the previous stuff I did isn't good enough", that's probably the story of my life and I'd much rather improve than never learn it.
I'm still looking for evening courses, but I'm not holding my breath just yet. I did use to work somewhere which had a lathe I could have used for my own stuff, but left there a year ago or so. But that would have been really handy.
That John Hainings Suffolk Dredging tractor looks really interesting. Where did you get the castings from for it? Always nice to do something unusual like that!
If I do start thinking workshop, how much space do I need to be sensible? I am planning on a 6ft x 6ft shed... Enough for a lawnmower and hedge cutter... Maybe enough for a small later or mill too.

I started with a Stuart 10H, I learned a lot and gained confidence, not to mention a nice looking model at the end of it. Worth a look.

If you are in the Gloucester / Worcester area look up MSRVS via Google. A really friendly bunch. Grum

I recommend Stewart Hart's PottyMill as a starter engine.
Made from stock metal - no castings. Inexpensive. I found it a good balance between simplicity and difficulty. Pushed my machine skills without frustration making it necessary to kick the cat or take to alcohol! Didn't find any errors in the plans, plenty of others have built it if you run into trouble, and Stewart himself is active on the forum.
Certain lucky chaps are workshop naturals. Their saws cut straight, taps never break, holes are always in the right place, perfect finish, and they never crash the saddle or cut a wrong thread. You might be one of them.
I'm not like that at all! As a clumsy novice I found it best to start simple and work up. Much practice, forum advice and cursing has made me the advanced bodger I am today. Although I can do good work, it takes forever and I regularly spoil lashings of metal on the way. Every time I do something I get a little bit better, it's just taking a decade or two longer than expected for me to reach exhibition standard!

Re: machining experience (zero)... some thoughts
The SMEE run courses on “Basic Training for Model Engineers” , “Lathe Tool Grinding” and “Milling”. I’ve done the lathe tool grinding and milling courses both of which I found useful in raising my knowledge base
The SMEE run a Building a Simple Steam Engine (“The Polly Course). I haven’t done this one, but those that have give it a ”thumbs up” .
The bad news is that the Polly Course only runs one a year and has already started

Thank's for reminding me I'm not alone.

I had not realised SMEE did courses! That is interesting to know. I'm not sure how practical it will be to do the Polly course, but the first workshop overview kind of course might be good to get a look in. Thank you!

All of these ideas look good. Is there a list anywhere of projects which require no castings, so just made from off the the shelf stock metal? That way, when I muck up I'll at least be able to replace the part without too much strain on the wallet.

I haven't seen the SMEE courses, but have signed up to a two day course on small lathe engineering at Axminster, from recommendation. Mine is in Aug, but there are more.

I'm not sure how much knowledge you have of the processes involved in even a project not involving castings.
If you dont have a lathe or mill or access to them you may as well save your money.
Hemingway kits are about as basic as they come, with a box full of metal cut to rough size and the engineering drawings to turn them into the required parts for the finished project. If you have no machining experience and no machines I dont think you will get very far. There certainly would not be enough time on an evening class basis to learn the skills and machine each part.
I do hope you were joking about the 6ft square shed, you need a lot more room than that for the things you are looking at building.

In your first post of Sept last year you said you were considering a traction engine as you also say in this new thread
Quote - So I was considering the idea of doing a miniature traction engine of some sort. Because that’s just how I roll.
Is this still the case ?
Plasma is spot on with shed size comment.
PS - a google search inputting STEAM ENGINES FROM BAR STOCK will provide a mine of information. Also there is a model engine forum - home model engine maker - which may be of interest to you.

If you google PYRTE traction engine you may find this one suitable.

I was in the same position as you. I fancied building a beam engine but, not knowing how well I would manage not being an engineer. I didn’t fancy shelling out on a castings kit because of the cost. I finally decided on building the beam engine by Julius de Waal. It was built totally from scrap or basic metal stock. I started it about 3 years ago and have had it running on air. I am in the process of painting it and making a suitable mounting block to finish it off. It was a wise decision as I had to re-make several bits and have scrapped a fair bit of metal in the process. I found the drawings online and I did depart from the spec on occasions. I haven’t added up the cost but I’m sure it was way cheaper than a beam engine casting kit and of course there was no initial outlay, I bought the bits of metal as I needed them. Hope that is some help.

HI, there is no castings in the Suffolk that's why i liked it at the time. All square edges to work from.

I'm building a 3.5 inch gauge britannia in a shed with no problems. It's snug but if you are organised it isn't an issue.
