a small update

I faced of a piece of 38mm round stock in the four jaw chuck till I go the correct sizes.


then lined up for the center of the cylinder and drilled it out in the lathe, increasing the drill size 1mm at atime till I got to the required size



then with a reamer in the chuck in the tailstock I reamed the hole to finish the cylinder. I turned the 4 jaw chuck by hand as i slowly turned in the reamer.



thats all for now :D

Like the use of packing under the jaws to stop damage  :thumbup:  nice one.

Thanks Stew :D
here are a couple of pics to show how they fit to the loco. I have drilled and taped one hole on the front of each cylinder for mounting
the other hole will be marked out after final cylinder alignment  :D
I havent drilled the port holes yet so still some work to be done. Im going to need a Mill for this I think to get accuracy

Hi Shoey

You can sucessfuly mill the ports in a lathe using a vertical slide.

This is what they are like you can get them to fit most lathes.
