I intend to add pics of my progress.

I am going to machine the guides onto the valve chest.

I messed up with the cylider barrels, and I now have 1 3/16" bore and not 1 1/4". i doubt it will make much difference to me.

When you said you'd messed up, I thought perhaps you'd gone over, now that might have been a problem, but under all OK, done that myself. Nice work so far. Ian S C

Thank You. I made the OD of the barrel too small. the wall would have been less than 1/16" at 1.25 bore.

[HobbyNutParticipant @hobbynut]

The cylinders are coming along.

[HobbyNutParticipant @hobbynut]

Last night I made up all the rod guides and fitted them. I thought that I may paint it green, so I tried out a bit. I don't like it much, it is too light, needs a darker shade I think.

You're really pulling trees up now.Looks like you're level with the series.

I'm chewing the cylinders out of some cast iron weights,given to me by a farmer.

Does anybody know if the insulation recesses are necessary,or will they be ok left solid.Most people will use insulation but I wonder if that is because the recesses are already cast in,so they do it ?

I understand that the cols cylinders will take longer to warm up,but is that a big problem???

Hope someone can advise please. John

I am almost up to it. I have to make the slide valves and pistons yet. I will try the pistons tonight.

The slide valves will take a night or two. I only have a "FIRST" Mill drill that is 100% digit operated. My digits get a bit weary at times! The only electronic digital equip. in my shop are the calipers.

My lathe is a 30 y.o Hercus 9" swing x 40" centers.

[HobbyNutParticipant @hobbynut]

I did make 2 pistons last night. I was only able to fit the rod to 1, and fit it to the cylinder. lots of lapping etc. More than I imagined.

[HobbyNutParticipant @hobbynut]

Made the slide valves and fitted them. The pistons and seals are also fitted.

[HobbyNutParticipant @hobbynut]

Back to making things from the latest installment.

The Cyl drain cocks under construction.

[HobbyNutParticipant @hobbynut]

The drain cocks are now assembled and mounted on the cylinders. I made the connecting link and all the other little bits last night. No pics yet. I will take them tonight.

[HobbyNutParticipant @hobbynut]

I am still working away. I used the 65000psi drill and file to make the motion pieces from the last installment.

[James SuttonParticipant @jamessutton25895]

Wish I had access to a water jet cutter like that. Would certainly speed up the plate work. I found a local machine shop with one but haven't made any contacts there to see if I can get some small run items done.

[HobbyNutParticipant @hobbynut]

James, it is easier on them if you can give them a digital file of the pieces that you want. either a .dwg or .dxf.
