A little more progress on the cylinder. Got the three port holes milled in the steam chest (photo1), then the holes from each end of the cylinder to intersect the ports (photo 2), and photo 3 shows that they do in fact intersect. More later today.

Haven't visited this thread for a while and you're making excellent progress. :cartwheel:

Nice to have all that shop time now that you're days are endless Saturdays, punctuated by the occasional Sunday.

You're better to just use lots of shop time, today I practally wilted walking from the house to the shop. :facepalm:

Thanks Craig, and today was a bit cooler even. I had to come in after a while even so. The humidity is terrible.

The cylinder is done now except for the holes for the upper and lower heads. After centering the bore, I stepped off to drill the inlet port on the top side and the coubterbored hole for the gland on the bottom (photos 1-3). The tapped holes for the steam chest had been done previously (photo 4). Finally the latest family shot. Now have to finish up several things on the frame before I can go much further.

Looking great Bill. Are you going to paint or polish the frame since yours is a bronze or gunmetal casting? And, before Jo asks: are you gonna replace the socket head cap screws on the valve chest for some proper studs and nuts  :stickpoke: :stir:? Keep it coming; seems like you are getting into a rhythm  :cheers: :ThumbsUp:.

He's in a rhythm alright. Just look at his "found a peanut' thread.  :lolb:

Looking good Bill.  :ThumbsUp:

We will see once it's done Cletus. Leaning towards paint or powder coating. Been wanting to try that. Another area I need to plan for in the shop renovation. Crap, I may have to expand...lol.

Oh , and will likely do studa and nuts, but I am not as obsessed as Jo!!

One has to have little pleasures in life... I know sometimes it seems they have become a big obsessions you just have to work at it  ::)

Here are some pics comparing studs and nuts with SHCSs.  The nuts are 3/16" across flats. I think 5/32" would be better but don't have any on hand. What say you?

I would vote for the smaller of the two. Though either is better than the SHCSs. Make one up as a test? Could quickly file or mill down one of the ones you have.

Nuts are a wee bit large in my opinion. Iíll look at mine,but, I want to say they were 3-48. Really if you have a hex collet block, you can shape the nut to fit the stud

Well niether McMaster nor PMR has 5/32" brass, so looks like I will need to make some from round stock. Cletus, mine calls for 2-56 threads on the steam chest cover and the upper head.
