Alyn Foundry:
CHUK " V "

The Vee Twin, my liking for them possibly inherited? Dad drove and competed with Morgan three wheelers through the late 40's and early 50's fitted with engines from Anzani, JAP and Matchless, he loved them.

As a natural progression my CHUK range developed starting with a vertical then an inverted vertical and onto a horizontal. The engines were conceived on a modular basis so the same patterns and castings could be used over and over keeping production costs to a minimum. CHUK 4 ( an inverted vertical twin cylinder ) is still in part built form and will be finished when it's finished.

The Vacuum, flame licker/gulper engine is one of the simplest to build and equally easy to run. This was the main reason for its choice as a build project aimed at novice entry level to model engineering.

I mentioned the concept to Jason Ballamy whilst he was helping me with some patterns for my long term project, the Brayton Readymotor. Within a couple of days I received 3D images of my concept via email. Several more interchanges later and CHUK " V " became a reality. To see a pencil sketch become wood then metal in a fraction of the time it used to take shows the amazing power of CAD and CNC . CHUK " V " ? Well the Roman numeral for five is the letter " V " quite an obvious choice really. Whilst the concept is mine due credit must go to Jason who has virtually designed the rest of this engine.

The number 5 will predominate in this particular build and my choice of using Aluminium instead of good old cast Iron is based upon a chance sighting of a Stuart Turner " bottle " steam engine. I was really taken by both the shape and nicely polished surfaces. Cast Iron is still in predominance as both air cooled cylinders, pistons and heads will be made from it. The engine will also use my recently improved " rotary " valve and
" Chipmaster " exhausts.

What will follow is our documented collaboration of a new engine from the Alyn Foundry stable. Some Iron castings are still on order but the Aluminium crankcases arrived yesterday from my dear friends at Madeley Brass. Hopefully we'll see a working Vee twin vacuum engine for our efforts or perhaps a nicely polished door stop? Time will tell....

Now over to Jason....

I know, Jo....

Who'd have thought? Jason making patterns?

He's damn good at it too!

Oh, I forgot to mention the flywheel.... It's a rather " pretty " IRON one too.

Jason is irrelevant  :lolb:  I am thinking about if a Vee twin flame licker would feel right  :thinking: .


I don't like the Stuart Vee twins: They seem to be a model designed to meet a current trend of men who wished they owned a big Vee twin motorcycle. Having owned Vee twins I can confirm I sold mine and kept the Norton  :embarassed:

Alyn Foundry:
Well....

If I'd have been the remotest bit interested in motorcycles it would have been a Brough for me Jo.

A tangle between me a Honda CD175 and a rose bush on my garden path put me off two wheel transport, permanently. It didn't stop me acquiring a rather nice 1925 350 cc BSA flat tank though. The riding was always undertaken by Martin when taken to the Steam rallies.

I'm sorry you feel the way you do about the model but I happen to like Vee twins.

Cheers Graham.
