woke up at 4 am this morning. Couldn't go back to sleep so I went to the shop. I started in on the eccentric straps. I had the water jet cut. The eccentrics I machined a while back waiting for the cylinder castings.

I got the mounting holes drilled in the valve chests today. Tomorrow I'll finish up the packing gland then drill and tap the cylinder block. Then, make the valves and tie everything in :D

I got the rocker arms done. The blanks were water jet cut then a rotary table operation then a trip to the lathe. I hope to have the valves done tonight.

Milling with a drill chuck? (Third picture down).
Not really recommended.

i agree Harold, milling with a drill chuck is a recipe for disaster. i have seen them pop off the jacobs taper
