Cogsy,
Thanks for your comments and advise.
Bellow is a photo to show the finishing I got on piston liners.
The way I machined the cam lobes, the end mill produced a crown on the base of the lobe, you can see it on the photo bellow.
To remove the crown I grinded the lobe moving the grinder chuck by hand from one flank to the other flank. See the result bellow
Boring the piston pin hole
Alining the bore to machine the slot for the conecting rod
Then I took the piston to the lathe to remove the epigot used to hold the piston on the milling vise. I used the pin hole as a stopper to ensure all the pistons had the same dimension from the center hole to the top of the piston
Thanks,
Edi
