| John Hill:
First step, boring the cylinder using a boring bar I made. Cylinder roughed out and a smaller diameter for the valve, holes drilled for the steam ports.. Of course if I had been smart I would have drilled the holes for the ports prior to boring but I didnt so back in the lathe it goes for a light skim to get rid of any burrs from the drilling. Decisions, decisions! I have to decide what type of valve to use, a simple spool type would be easy enough but a rotary system would get me to use a couple of spur gears I have. :scratch: |

Stew --- End quote --- Thanks Stew. The part off tool was a 'set' on sale which was still quite expensive but I treated myself to it. A month or two later I had broken both ends of the blade and I was shocked to find the blade now cost more than the 'set' had. I gritted my teeth and bought another blade but I am blankety-blank careful about how I use it! |

This brings back memories. --- Quote ---A month or two later I had broken both ends of the blade and I was shocked to find the blade now cost more than the 'set' had.

I still go thru all that at times. Can't wait to see how this one turns out John. Should be something special. John |
