If at first you don’t succeed…

Try again.
The small reversing handle lock on the horizontal mill engine took 4 attempts.

Most of the components are made. That is my blood staining the plans.

The lock is made of brass. About 32mm long, then bent into shape.

From the left.. 1. broke when turning the thread. 2, cracked during bending, not enough heat. 3. Too much heat melted the surface. 4. Success.
And on the same subject, the cylinder head and guide went well until I neglected to remove it while finishing the guide block.

I might have mentioned this one previously. It still rankles.
