Started thinking about these pcs the last couple of weeks.

Going to attempt fabricating them.

Made 12 of these so far for 2 sets. Will make 3-4 more sets before moving on to the top head.

Working on some little pcs.

Pivot pins for the trailing truck.
Small tie rods
Tie rod ends
Brake eq

The McMaster fairy will be bringing me a left hand 1/4-28 die tomorrow to finish up the tie rods.


Nothing major accomplished, but at least it's something to cross off the "to do" list.

Op1 finished on the top head.

Need to drill the hole next, mill the excess off the top and then setup to mill the top profile.

Getting back into the Mikado again after a busy summer.

Here's the link brackets that I was able to do over the holiday.

Harry,
Are you the only person working on the project? It seems it started off hot but has stalled the past couple of years. Any idea when you think the first one will be running?

Ben,

I took a much needed break! Especially after scrapping a batch of heart rockers, pilot eq beams and a couple small pcs.


Plus, I tend to do very little during the summer


Others are working.....but haven't posted.

Hint hint Dale


Dale is building 2, I'm building 2.....possibly 4, if I can't find a home for them. And there are 4 other guys

Swarf: an ugly Klingon, or any of the debris from machine operations. Pretty much slang. Been run over by this word for 30+ yrs.

According to the military, and Whiting Crane, a template is used to establish and read three Tram points on a load lifting hook. The template then forever is the standard that lets us observe any distortion or deviation in the original hook due to stress or wear, causing bending. In this case between shank, curl and tip, being a described triangle.

In steam, tramming is indeed a method of checking wear, and setting valves links, back to design specs, as wear shifts these dimensions. A way of checking benchmark points.

In machining, it has become a slang term for setting parts and milling heads, into perfect alignment for square. in other words a working setup is 'trammed in' on a mill table to make a run of parts. Also to establish true 90* tool setup to the table, for the least amount of cutter marks, that also depend on the tightness of the machine. Engineers drive me nuts with that phrase, as they generally dont start out with any idea of how tooling removes metal, and the ideal, does not exist. Same as a CNC Operator, is generally a loader, and does not have a clue on programming, as that comes from some office.

Thats why I like a hammer. Give one to somebody that knows how to use one, and stand back, it can be an education.
