French Beam Engine
Bogstandard:
Don't worry Pete, excellent first try.
What you have to realise, I have been making them for a long time, and know a lot of the pitfalls, but even so, I still make mistakes, and have to 'modify' on the run to get them looking OK. It is knowing how to rescue when they do go wrong that is the secret.

doubletop:
Thanks John; it went pretty well really and your instructions helped immensely. It was also helped with me using the same DRO and making a version of the same flywheel as in your example, albeit with a smaller outer diameter. So it really was a case of do what it says on the box.
I did notice one small anomaly with your instructions that comes about with making a smaller diameter using the large 8mm radius fillet. When setting the X offset for the spokes on the outer diameter the offset moves tangentially to the PCD. As I only wanted a thin outer ring I had to compensate by reducing the Y slightly. I didn't do the maths and just reduced Y 'a bit'. You can see that in an extreme case of a large radius fillets, thick spokes and a thin outer wall moving Y to the PCD - fillet radii and X to 1/2 spoke width - fillet radii you could end up drilling outside the outer diameter. (hope you follow that?)
Thanks again
Pete

Pete,
I think thats a pretty good flywheel :clap:
It could be rescued - on the fly so to speak :D (on the fly) :lol: :lol: :lol:
But there again I'm a lazy o' sod :)

I thought of trying to rescue it but opted for completing it as it was to see if there were any other pitfalls. The fact is John instructions are so easy to follow that doing another one, and getting it right, is good training for all the others I may need to make in the future.

Does that mean we will see more than one new Engine at the next Meet :whip: :whip: :whip:
