And last one for now, the brake wheel, ratchet, pawl, and base. All brake rigging will be functional, both manual and air. No shortage of things to do! Jack Attachments:

Here is a photo of the water tank filler hatch. The hinges are actually Nickel Plate Berkshire hinges, just put together with the top part of the hinges upside down. Go with what you got! Jack Attachments:

And here the base has been made of free machining brass and is now ready to be silver soldered to the cylinder. Attachments:

Here is one of the cylinder heads ready for silver solder. There are two bosses for the air inlet even though only one will be used. The put two bosses so it was optional which side was used for the inlet pipe. Both will be drilled and tapped for 5/32" MTP and one will be plugged. Attachments:

Hello My Friends Here is some progress on the Disney American. The brake cylinder has been mounted up and the brake rigging is mostly finished. All the links and levers are in place. The brake beam safety chains along with the truck safety chains remain to be made and fitted. Attachments:

Here is a bracket that was made up to support the top end of the brake wheel shaft. These early engines had lots of cool little bits to make. Attachments:

Last one for now. This is a dummy lubricator that fits to the steam chest. Masters were made and sent off for investment casting. That way only one of each had to be made. Seems like cheating in a way. Too much fun! Jack Attachments:

Hello My Friends
The brake wheel is a investment casting but the master was fabricated. The spokes started out as a turned ring with a groove cut into the perimeter that would later engage the rim. After the disc was turned, the spokes were marked out with a card stock pattern, roughed out with the bandsaw and then filed to shape. The rim was probably the trickiest bit to make. Round brass of the correct diameter was chucked up in the lathe and bored to the ID, then as much of the rim was turned as possible using what form tools already on hand and files. The rim was parted off and gingerly chucked up and the remaining inside radius finished with a file. The spokes were then snapped into the rim utilizing the groove that was previously turned in the OD of the spoke disc. The boss with the square hole was then made up and all was silver soldered together. Parts like this are a delightful little puzzle to make as they merely have to look good, not like machining cylinders and valve gears and such. The spokes are not precisely symmetrical, but to the eye they look just fine. Who cares anyway, just get er' done.
Happy Model Building
Jack

Here is a close in shot of the brake wheel, ratchet, pawl, and latch base. The parting lines on the brake wheel still have to be cleaned up with a file. Attachments:
