MikadoCoversCompletion15Nov06 008 15-Nov-06 The finished Piston Covers!!!!

MikadoCoversCompletion15Nov06 007 15-Nov-06 Last step in finishing the rear Piston covers; machining the boss off.

MikadoCoversCompletion15Nov06 006 15-Nov-06 Closeup of the finished rear valve crossheads.

MikadoCoversCompletion15Nov06 005 15-Nov-06 The finished Valve Covers!!!

MikadoCoversCompletion15Nov06 004 15-Nov-06 We also opened up the front valve covers also by This was not call for in the prints, but similar to the piston covers.

MikadoCoversCompletion15Nov06 002 15-Nov-06 We decided to 'open up' the valve ports a little bit and mill some exhaust steam passages. This was not call for in the prints, but similar to the piston covers.

MikadoCoversCompletion15Nov06 001 15-Nov-06 One of the last steps is to drill and tap the packing gland holes. It's a close one for the spotting drill and tap -- check out the clearance between the side of the crosshead jaws.

MikadoRearValveCovers26Oct06 003 26-Oct-06 A one hour setback: the Valve Crosshead guides were machining with a taper. Investigation found the block was slightly tilted front to back. Much fussing later, and stacked paper shims of 0.0013 and 0.0018 removed the taper back into acceptable limits.

MikadoRearValveCovers26Oct06 002 26-Oct-06 The crosshead jaws machined to width. Next, machine the step in them to make the crosshead guides.

MikadoRearValveCovers26Oct06 001 26-Oct-06 Dialing in the Valve Crosshead Jaws mounting fixture to be parallel to the table travel.

MikadoRearValveCovers14Oct06 004 14-Oct-06 The completed Valve Crosshead holding fixture (the aluminum block) with the crosshead bolted on and ready for use. Next time, machining the crosshead slots into the casting.

MikadoRearValveCovers14Oct06 003 14-Oct-06 Kids, don't try this at home: Lacking a boring head which could go out to 1.750

MikadoRearValveCovers14Oct06 002 14-Oct-06 Having reached the limit of the boring head, we put a fly cutter in to complete the hole.

MikadoRearValveCovers14Oct06 001 14-Oct-06 After fly cutting the top square to the angle plate, we begin to bore out a hole to bolt the Valve crosshead guide to.

MikadoRearValveCovers11Oct06 003 11-Oct-06 Fly cutting the aluminum blank square.

MikadoRearValveCovers11Oct06 002 11-Oct-06 Drilling and tapping the piston crosshead guide lugs in a horizontal rotary index friend Alan H. gave me.

MikadoRearValveCovers11Oct06 001 11-Oct-06 Checking the trueness of the horizontal rotary table. Even though it is a used veteran, it runs with 0.0005

MikadoPistonCovers04Oct06 004 4-Oct-06 We made a custom six inch long end mill holder because the regular end mill holder and spindle would be in the way of where we wanted to mill.

MikadoPistonCovers04Oct06 003 4-Oct-06 Bill taps around on the Rear Valve cover to align the casting in our 'chuck on a table' holder.

MikadoPistonCovers04Oct06 002 4-Oct-06 Here's what it looks like as we work on the rear valve covers.

MikadoPistonCovers04Oct06 001 4-Oct-06 We discover the holes previously drilled are 0.014 off. We don't know why, maybe the y-axis handle got bumped. We have to make a custom endmill holder to mill the holes back to their proper place. A minor, but two-hour, setback for that nights activities.

MikadoValveCovers18Sept6 005 18-Sept-06 With the finished small Jacobs drill chuck held in the mill, we proceed to drill the rear valve cover holes.

MikadoValveCovers18Sept6 004 18-Sept-06 Since the center drilled hole in the end of the arbor is way out of center, we use the steady rest to hold the chuck and finish the arbor to size.

MikadoValveCovers18Sept6 003 18-Sept-06 Making an arbor for a small Jacobs chuck. The drill chuck is clamped to a dowel pin, we indicate off the chuck body to remove the run-out.

MikadoValveCovers18Sept6 002 18-Sept-06 The most challenging part to chuck so far - the rear valve/crosshead casting. We will need extra long drills and taps to complete this job.

MikadoPistonCovers13Sept6 004 13-Sept-06 Sweeping the rear piston cover to center it. Thanks Bro' for the Indicol!

MikadoPistonCovers13Sept6 002 13-Sept-06 Machining the crosshead guide brackets.

MikadoPistonCovers13Sept6 001 13-Sept-06 Drilling the bolt circle in the rear piston cover. The only way we could hold it was to remove the 4-jaw from the lathe backing plate and bolt the chuck to the table. Using a bolt circle program on the DRO meant we did not have to revolve the cover.

MikadoPistonCovers2Aug06 003 2-Aug-06 A thin grab in the 3-jaw. With the parallels temporarily in place to try and make the outside parallel with the inside, the piston cover is chucked up for turning and facing the inside.

MikadoPistonCovers2Aug06 002 2-Aug-06 Turning the relief for the bolt holes

MikadoPistonCovers2Aug06 001 2-Aug-06 Rough centering the front piston cover.

MikadoSteamChestCovers26July06 006 26-July-05 Rough turning the back of the front piston cover.

MikadoSteamChestCovers26July06 005 26-July-06 How to set a carriage stop when you do not have a micrometer stop. Use something, in case a drill bit, which is the same size of the offset you are trying to set. Shim stock and dowel pins also work.

MikadoSteamChestCovers26July06 004 26-July-06 Turning the back of the valve cover to size. We found a good insert with a chip breaker on it, prompting me to grab a piece of plastic to use as a guard.

MikadoSteamChestCovers26July06 003 26-July-06 The valve cover after roughing operations

MikadoSteamChestCovers26July06 001 26-July-06 We start work on the cylinder covers. We start with the forward valve covers, turning the outside diameter, the stepped recess, then drill and tap the center for the decorative cover bolt.
