Re: Power Model Supply Duplex Steam Pump Drawings

Are you referring to the duplex pump sold (long ago) by Cole's Power Model Supply?
That's the name I know of associated with it.

Wow!
I would love to see a video of your machining processes. CNC I presume.

We just might get to see videos taken by the sky crane on its final trip!
Hope so.

Re: Second Reconstruction of the Mongrel 2-6-0 "Emma"

There is a 4-8-0 under construction in the Portland, OR, area, based on the Allen 4-6-0.
It will be pretty nice! It is being designed and constructed by a very talented builder.
I'm not sure where this new locomotive is sequenced in his shop full of locos.

Re: Moriya Stirling Engine Build

Excellent work on those finned cool-end cylinders!! Thanks. Even my wife thought they were pretty. I noticed that your engine has five thicker fins instead of seven thinner ones like the plans show. Do you remember why you did it that way? -- Russell Mac Russell: My fan was a gift from the students...

Re: DRO advice.

Thanks for the photos. Very helpful. I had a similar mill except for a step-pully speed adjust drive on top and the "nod" arm. The dials at the hand cranks could be loosened and zeroed with an allen hex wrench to turn the setscrews. They were hidden in very small holes in the dials. And I never used...

Re: DRO advice.

Lewayne:
It would help us answer your questions if we knew what mill make and model you have, including posting some pictures.
And you can do a search here for previous postings on milling machine DROs, as there are several. Possibly many.

And your slow turning technique sounds very familiar. Patience = good results.

Re: Curious what everyone else does after a swarf filled day

I am also with Jack and Greg, cleaning as I go.
I sometimes get harassed for having a clean shop, but nobody ever complains about my product results.
Like many other things machining oriented, the process takes time.
Cleaning is part of that.
