Phil, that's a superb essay into some terrific forethought.   :praise2:

Don't let those new castings spoil the flow on Agnes though - believe me that's coming from someone who knows about these things  ::) - I'm struggling in that direction at present  :-\

Great work Phil - Ramon

Cheers Kerrin

I have just found some 25mm square ceramic tiles which I am considering using for the floor for Agnes, everyone goes for the diagonal pattern but I was wondering if I should be different and go for tiles in line with the engine.

Here are a couple of shots showing the sample tiles in place both ways, I think I know the answer, If you try to forget you have ever seen this type of floor before, do you guys have any opinions as to which will look the best based on the photo's.





One other option is to use just the white tiles all over. ( the tiles are a semi matt finish by the way)

I always thought that these big mill engines were originally mounted on granite flags with iron access plates to the lower workings.

You are probably correct, that is why I cannot decide what to do for the best.
I have photo's of some engine houses showing this type of floor, but they are probably from a slightly later date than Agnes, so maybe I should save the tiled floor for "Bradford"

Next question, where do I get 1/16 scale granite flags  :help:

Here is one of mine with the tiles square on



By a strip of worktop edging for a granite eddect worktop and cut into suitable squares. Its just Formica type high pressure laminate and can be stuck down easy enough. Or plaster the base and scribe in the joints and finally paint as any granite you by will have a full size pattern not 1/16th

I also doubt that the victorian tiles were 16" square, 6" is more likely so you want 3/8" on the model or 8" at a push at 1/2"

I still need to give a lot more thought to the floor options, in the meantime I have been working on the flywheel though.

In order for me to make a form tool for slotting the 200 barring ring teeth, I needed to produce the mating gear for the barring engine.

Here it is being machined on my little Mikron hobber.









Well actually I made three all at the same time, it takes only a few seconds longer to machine the teeth.



Here they are laid over the barring ring drawing just to give an idea of how they fit.

Brilliant gears, think I prefer the tiles straight on.

Just a thought, but finding a friendly stonemason with a diamond saw could be a source of custom cut granite?

Stunning work by the way - I'm seriously impressed  :ThumbsUp:

Phil,
Perhaps most people go for the diamond pattern because the square pattern will show up slight misalignments between the tile and the  engine.

Thanks for all the positive comments guys, it makes it all worthwhile.

Agnes has a new boyfriend, he is called Sanderson.

Phil

I have a set of Sanderson castings.  Unfortunately, the cylinder casting was no good, so I'm going to have to fabricate or machine another one.

Or ....possibly.....if you befriend the local countertop shop....you could cut them from Corian.

Lot's of possibilities there.
