I wonder if these people actually sell engines as they are building a collection worthy of the finest museum. There are more lovely engines to model in their collection than you can imagine.
Maybe they ought to laser scan them or some such so we can access 3D accurate dimensional models on-line - then we could have a go at making some. This sort of thing is routine these days and can be very accurate - police even use it for accident scenes.
If they have open days, that almost reinforces my idea that they are heading towards having a museum/private collection status (and why not, I would love to have a tiny fraction of this collection, even as models).
However I only discovered them after my job moved me from Kent to Cheshire - so I was delighted to find they were in Preston... which is in easy reach. Then I found they were nothing to do with Preston in the North, but back in Kent where I had come from.
Isn't it funny how the grass is always greener elsewhere, and when you get there they point you right back where you came from!
Looks great, 3 questions though - 1/ what holds the bearing in place. 2/ would there be any play in the top of the base near the fly wheel, as the cast version looks a lot thicker. 3/what are you doing for the fly wheel, home made or cast.
a. The bearings can't really go anywhere as they are constrained by the flywheel in the centre and the crank arms on the outside. That said however, the are also secured by the oil cups which pass thru clearance holes in the caps into tapped holes in the brasses.
b. I am hoping (read pretty confident) that the metal is thick enough, in tandem with the stiffening effect of the bearing bases, to avoid any such problem. Worst case I can alway retro fit some stiffening pieces.
c. I can't seem to source cast flywheels for love nor money these days, and even if I could, a 4 curved spoke one would be fairly rare, so a fabrication it will be. Got a scheme nutted out, which will probably be the weirdest flywheel build in history. More on that anon, when I see if it's going to work.
