Really nice work. I have often thought about using CAD but I agree that getting the pencils back out is nice.

Very nice to see more small scale work. Another one here in agreement of drawing by hand. Have to get the use out of my 40 year old drawing set made in czechoslovakia. Keep the updates coming.

I'm spending too many hours just looking at the parts I've made so far.....

Don't worry Nigel - you are not alone in doing that!

Nice work - look forward to seeing more.

smiley Hi Nigel

Thanks for posting this and the link to your blog site in your first post. Loads of interesting reading there.

I was instantly attracted to the post as I am very much into toy engines, Mamod, Wilesco and Mercer for traction engines. Like you I am inspired by Cherry Hills work; I am a Fellow of the IMechE and I have made the pilgrimage to see her models more than once. They are breathtaking, so small that the close-up views in the book hardly make sense.

Your idea to make this pretty and fat-boilered Burrell is a sound one. There is plenty of space for heating area and transmission in the design, where a more efficient, more modern (is that the right word in 2020??) prototype would be a tight fit. You might want to nudge the size of the cylinder a little bit but it won't be much; the DM Mercer has a tiny cylinder, no steam jacket, only two small wicks and can pull a child, that is powerful enough.

Your engine will be more like a Myfordboy, due to the techniques used. That is a good runner but not very pretty and I am glad you are putting the work in to do a classier job.

I look forward to further instalments with great interest.

As to drawings! Bassett lowke did a 1.5" scale Burrell traction engine. This may help as the drawings were done in 1949 I think. Give me a PM. Noel.

Looks a tidy etch and makes good detail on the model.

Out of interest, is there an issue with etching after soldering the hinge? Is there a reaction there, or were you hoping for less solder creep? Asking before I try to copy your techniques!

Hello Nigel ,

Its great to see someone showing models on the site ! Instead of the usual boring subjects . After all it’s called model engineering ! Not what lathe etc should I buy .


Tony Wright raises an intesting point .

Yes it would be good to see someone showing models so how about it please, members?

Would be good if he  posted a picture of his Minnie to get the ball rolling.

I will sort some over the next day or two,

Hello br, Re Minnie long gone I’m sorry to say .Had to sell it due to lack of funds . But if anyone has any problems with the design please give me a shout. Tony.

Can you get your suggestion off the ground with someting else in a new thread rather than gooff topicin this one?


Apologies to Nigel
