Hello from my little island at the very west of France

It’s time for me to describe building of Wyvern from Edgar T. Westbury the famous model Engineer, a star for me.


At the beginning of this month, I decide to buy the complete kit and draws from Hemingway Kits. Very good contact with a serious seller and short shipping time to my island.



After opening the parcel, I have noted the quality of casting and the packaging.
As I’m French :rolleyes:, I must convert Imperial to metric before machining parts and simulate assembly with SolidWorks to confirm.


I began by the lower side of the sub-base


Following, the main bed

Didier,

I'll be following your build, it will be interesting to see what the actual castings look like.

Didier,

It is good to see another "engine from castings"; I have pulled up the chair and will be following along with your build.

Thanks for sharing.
Dave
 
Many thanks to all,

I'll try to send posts every weekends along building.

Regards

Didier
 
Hello
I am back for the weekend and take time to write the post. I continue to convert and simulate with SolidWorks.


General assembly:

Piston and connecting rod:

I think it’s a good way to validate assembly and correct eventual mistakes before machining castings.
I also made a plate for the main-bed to have good reference for setup before machining.
By example: Machining the main bearing seats:[FONT=&quot]

[FONT=&quot]As I’ve not sinus table, I use a specific assembly to set angle 30° - Thanks to Pythagorean theorem.

I set up the angle with my IPhone – Don’t laugh please, it’s enough for accurate in this case.


It’s time now to bore the first big hole. After marking the center hole, I use the lathe to drill.

Hi, very interesting

I have also a Wyvern in progress, have finnished the big parts and managed to try the operation of crankshaft, rod, piston, cylinder, together.
Will try to get some photos.
Got interested in your glass-tube oilers.
Are they home-made, or can you tell me the supplier.

Regards
Anders
