Vertical Cross Single

[Stewart HartParticipant @stewarthart90345]

Just started work on a Vertical Cross Single engine that is loosely based on the Kenion Engine at the Northern Mill Engine Society at Bolton, it follows the same theme as my "Helping Dad" simple mill engine and is aimed at beginners with a basically equipped work shop

Simple Vertical Engine Suitable for beginners

Look forward to it Stew. Will it use the same cylinder components as the mill engine as I know you were intending to base several engines on those parts?

Thanks Jason

Yes it will use a lot of parts common to the mill engine I've given it an extra 8mm of stroke to try and slow it down so the cylinder will be longer but apart from that it is exactly the same. I've still got one or two design issues to sort out as the build progresses and I want to try a different way of fabricating the flywheel.

And I also want to give it a tile effect base similar to the base you did for your Benson engine

I've been making rapid progress as I've been using my mill to make the cylinder parts.

Cheers

Looks good, eagerly awaiting plans.

Thank you Stew,

I have a part-built and raher small engine (about 5" high) based on a picture of a colliery winding engine that used the same parallel motion.

I lost the ancient ME that had the picture in and the project has stalled, mostly because I wasn't sure of proportions for the motion. Your pictures solve this for me .

The Kenyon engine has part that they believe are from a NE winding engine it was bought by a thrifty Yorkshire man about 1910 and installed in a mil in Huddersfield which it powered for many years before being scrapped and abandoned in a field before the Bolton Lads rescued it. It's an engine that fascinates me on my visits to the museum.

I've had quite a few attempts at drawing it but never been quite happy with the results, and this very much simplified version will be a long way off from being called a model Kenyon engine but it should show the Phineas Crowther parallel motion off well and I have a few ideas on blinging it up.

As for the parallel motion linkage one thing that I missed until Neil Carney, Diane's Dad Pointed it out, is that the cross link are at the 90deg position when the engine is 2/3 from top dead centre, as shown in the front view drawing, I thought it was mid point. If you watch the engine under power you can see this but it isn't obvious.

Just a bit of an update on work done

Flywheel fabricated

[Stewart HartParticipant @stewarthart90345]

Any way I've got it running

Its a bit noisy but that will tune out bits are catching or have an headache but nothing that a bitter of fitting can't sort.

Its on a test base at the moment I want to fit it to a tile effect base,

I'm also going to make valve for it.

Looking good Stew, I prefer it at the slower speed.

J

[Stewart HartParticipant @stewarthart90345]

Thanks Jason

Yes it does look better at the slower speed, its got the same cylinder as my helping dad mill engine but I've made it 8mm longer giving it a 40mm stroke to try and slow things down, at the moment its still a bit tight the lowest pressure it will run at it 20 psi if I can get it down to 10 psi it will be better still.

I've cribbed the method you used to make the tile effect base for your Benson engine.

[Stewart HartParticipant @stewarthart90345]

Well I've got it finished had a bit of trouble making the wooden base, when it comes to wood I'm no Chippendale and I'm not much for exotic dancing either.

I just need to go through the drawing and amend them where required, I'll be writing it up fro the mag over the next couple of week in the mean time it's back to the Simplex build

Looks good now its got a lick of paint on it.
