The valve gear has been completed. Photos: www.mikemassee.com/gallery/v/projects/allen_models_chloe/chloe_valve_gear/ I have just started that new gallery for the Chloe project photos and will be working my way backwards. For now that's the only thing there.
We made a modification to the pushrods, we added a hinge so that the rods didn't need to bend. It seems you go either way on this, and there are examples of both on prototype locomotives. We figure it'll be slightly easier on everything that way.
The cylinders are next. They are being re-machined right now, they are the old ones from the now-scrapped Chloe we started with. The question came up as to what to use to hone the inside of the cylinders. The best item anyone has come up with so far is automotive brake cylinder hones, the spring loaded kind with the flexible shaft. The way a friend does it is he submerges the cylinder in a coffee can of kerosene, and runs the honing tool on a cordless drill, while the cylinder is submerged.
A mechanical engineer and auto nut at work said it would be good to wear-in the honing pads first on some other object before attacking the cylinder, if it's a newly purchased honing tool. Any comments appreciated on the honing process, tips tricks and sound advice...
Robert Morris gave me a spare Allen Mogul headlamp casting on Saturday - he also has one on a Chloe he is working on and it looks great. You can see pictures of their semi-completed Chloe with that headlamp style here: www.mikemassee.com/gallery/v/livesteam/robert_morris_shop/
