Solution. Do NOT buy a round column mill drill. But, if like me, you came to that conclusion too late, here is my fix.... (and I have tried laser pointers, etc etc., none of which were satisfactory) https://wordpress.com/post/johnsmachines.com/14693 It was costly and time consuming, but it...

Made to Jerry Howell's plans.

Magnificent!!

StanStocker, I also made the 1779 24 pounder from Jerry Howells plans, and then a carronade, then an Ottoman Bombard, All 1:10 scale. The bombard is 515mm long. The photos are my latest model cannon, also 1:10. It is an Armstrong 1866 RML. I spotted the original at Port Fairy, Victoria...

Hi Jenny! Nice job. From you know who in Oz.

Hi Irek, I have recently finished a 1:8 Trevithick dredger engine, and had similar problems with the gas burner. The main problem is that it is an inefficient steam engine, made even more inefficient by being a 1:8 model. I solved the problem eventually by using a very large capacity burner...

Interesting video, and thanks for the noise warning. Unfortunately I was a bit slow turning it off. Horrible!

Hello Chuck, I have recently finished my second boiler, and you might find my blogs about the building helpful. They are at johnsmachines.com .Just a cautionary note... copper, silver solder and brazing gases are not cheap. I estimate that my 6" vertical boiler has cost at least $AUD1000...

Thanks for the mention Peter! I have posted a video and other pics of my Bolton 12 running on steam and construction at johnsmachines.com. John

Hi Peter, I used angle grinder gears for the governor of my Bolton 12. I heated them red hot and slowly cooled them several times, and was then able to machine them with carbide insert tools. John johnsmachines.com

Is the boiler still for sale? I would be interested. [email protected]

Hi Ned, I run my Bolton 7 with a 4" diameter boiler which I built from plans supplied by EJ Winter. I also used their castings for the firebox ends. It works perfectly well at about 35psi, although the boiler is rated (from memory) for 100 psi. The boiler looks the right physical size for...

Congratulations on your progress. I am very impressed by you managing to make the bevel gears. I "cheated" and modified some gears out of an angle grinder for my Bolton 12. I am interested that you have chosen a dark green colour. That is almost exactly the same colour which I am using on my...

Hi I built a Bolton 7 and then enquired about a boiler from the Bolton7 supplier. EJ WINTER Sydney. Kelly Mayberry supplied plans snd castings for s 4" horizontal boiler and that works very well. It can be seen working on video and photos at johnsmachines.com Not cheap though. By the time I...

Hello John, I have not yet installed any drain cocks on my beam engine, but in view of the cylinder size, I intend to install them at the top and bottom of the cylinder. The top cock needs to be positioned very carefully, so it will drain with the piston at TDC. I am not yet steam ready, just...

Hello John I have built an EJ Winter Bolton 12 recently. The ejw model is bigger than the Stuart model. You can see mine on johnsmachines.com. I am happy to help You will definately need the ejw plans for the ejw castings. Contact Kelly Mayberry at ejw John Viggers Jviggers@ iinet.net.au...

For CNC turning, I use Lazyturn. It is freeware, simple, and easy to learn. It uses dxf files and produces G code text files which Mach3 can use. Admittedly, the files do need to be checked and sometimes need some editing, but it is excellent value for the price (free).

This is my 2nd engine, again being made from castings and plans from EJ Winter of Sydney. Started Jan 2013, and about 2/3 completed June 2013. The 14 inch flywheel was right at the size limit of my lathe's capacity. The project has advanced significantly since these photos were taken. More...

I might bump into you there, while we are paying our respects to B & W.!! I am sure it is not an atmospheric engine though. It operates on positive steam pressure. I gather that it has been modified in the 100 or so years of its industrial use, and it was changed from single acting to double...
