I did get a chance to spend some time in the shop and here are the results.

The studs are for the piston rod glands and the clevis are the eccentric rod ends.

Nice work Ken. What have you made the studs out of. I used mild steel and nickel plated them. They seem to be lasting well. I remember doing all the studs more or less as a production run - took about 2 weeks of spare time. I was pretty good at thread-cutting in the lathe by the end tho'

Cheers

Paul, Thanks

The studs shown are made from 1018 CRS. I am planning on making the cylinder and valve chest cover studs from passivated 303 SST and having the mild steel hardware parts finished with grey zinc oxide.

I had the stock for the "Crosshead Guide Studs" cut to length and the end radius complete before I noticed that there is a discrepancy in the drawings. The stud is listed as 3/8 dia & 3/8-16 thread but the column and gib are drawn using 5/16-18 holes. Guess I should have checked before cutting. I was on a roll cutting stock and was set up for these parts so I forgot to check the mating part drawings beforehand. Oops!

For me threading is kind of a Zen thing. It takes enough concentration that I need to clear my mind of other thoughts. I kind of like it. Also, working on these small pieces is helping me gain some experience on parts that are easy to replace if I screw up before tackling the castings.

I take it your project has been launched and on the water?

Best wishes

Hello all,

In the category of "a little more action, a little less conversation" I have been working on parts for the York engine as of lately and here are some of the "fruits of my labor"

More to come....

Here are the eccentric rods (2 straight & 2 bent) and the front columns. These parts are 1018 CRS with a bright (polished) finish. Still need to do the final polish and waxing on the columns.
