ozzie46:

Its been a while since I updated this thread so here goes.

I made a plate to go on my cross slide to use it as a boring table to bore out the cyls.

Made a boring bar out of some rusty bar and put it between centers to do the boring. Used a set screw to adjust the cutting tool and another to lock it in place.

I used a auto brake wheel cyl hone to hone the cyls. For got to take any pics of that.

I used the off cuts of the steam cyls to make the end caps (?) for the cyls.

I cut off as much as I could on my 4 x 6 saw to make it as round as possible be for turning them in the lathe

For the steam chests I chain drilled around the inside of the blocks for the chests and cut out the center with a hacksaw,then milled the insides. I them made the valves and the vale nuts. The valves are cast iron and the nuts a re bronze. The cyls and the steam chest are sat iron as well as the end caps/ cyl heads.

The valve rods are stainless steel.

I did some profiling on the cyls to make them more like castings ala kvom.

I also took his idea of putiing 2 countersunk cap screws in th steam chest to keep them in place when the top cover is taken off.

I'm going to mill a .020 depression in the covers inside of the gasket area and may do the same for the top of the covers.

That brings it up to date as of today. I will profile the other cyl tomorrow.

The bolts in the steam chests are temporary, proper scale hex head bolts will be put in for the final assembly.

Nice work Ron, iteresting arrangement for the side valve.

You can get castings for this loco, but like that your build without them.

I think I'll keep my eyes open for a set of drawings for this loco.

Thanks for showing

  After reading your post I looked at the pic, :doh: :doh: :doh: didn't have the valve nut in the valve right. :loco: :loco:

   Model Engineer had the plans for free download a few years back but I think they took them down not long after.

   Thanks Stew.

In that case I've probably got them stashed away someware, I'll have to dig my back issues out.

Good going Ron :thumbup:

The steam chest and valve photo hat me puzzled for a bit - till I realised the valve was not in its correct place :-)

Did you get a mill in the meantime, or are you still using the lathe and the Nicholson mills ? - the rounding over on the cylinder looks great. And besides looking good, makes the block less "massive" so it will heat up quicker resulting in less condensation in the cylinder. Are you going to add drain cocks to the cylinders ?
