Musgrave Non dead centre Engine assembly

[geoff5269]

It's taken me about 6 months to build this Engine from plans by Julius, I have reduced it to 80% and it is made of Aluminium and Maple wood with Brass for the cylinders.
I was attracted by the unusual design and I hadn't used rotary valves before, the challenge is in the columns and the A frame.

Wonderful work on that engine!!  Have you tried running it yet?

[geoff5269]

Here it is finished at last and I'm very pleased with it. I might make some changes later but I'll give it a rest for now.

Very fascinating motion!   

It'll be interesting to see how much difference changing that middle piece will have on the engine.  It seems like it will improve it significantly to get those little links more in line with the cylinder rod travel.

That's a lovely looking engine, with a hypnotic movement - well done, grand job!

Here is the Musgrove with some changes I hope make it run better, I got a heavier fly wheel as the first one was only 260grams and seemed a bit light so I bought one made of Zermak which is 700 grams and was easy to machine. Timing is tricky with this engine so I found fitting a tube to the exhaust and holding it to your ear lets you hear the valve opening.

Great work!

Very cool! 

The wider triangle middle piece does change the motion quite a bit, doesn't it?  Interestingly, the little black connector (between the triangle and the piston rod) on the right side wiggles around a lot more than the one on the left side.  And I think the larger flywheel really makes a big difference too.

Well done!

Great job Geoff!  It looks really good!
How did you attach your pieces for the head?  Did you glue them? 
It sure made a big difference making the cross head a bit wider.
