Greg,
Looking very smart - the graduations look excellent what sort of tool did you use?
Nice bit of machining for the dovetails Smiley-signs107 Worthy

Found an engraving bit in some cutter I was given. Basically a D bit with a point, cut surprisingly well at about 3000 rpm.

Where's this "split cotter" and where does it go?

Its still the imaginary split cotter, two of them, to lock the tool angle and the assembly to a shaft. Maybe today, we'll see.

Nope Steve, pictures to follow. Interesting screw up today. Machined a pin to old two of the parts together. Machined two diameters and a shoulder then single pointed a 7/8 14 tpi thread on the end. Cleaned it up with a solid die, then parted it off. The thread is crooked to the pin. HOW!!!!!! The die should have followed the existing thread, I do this all the time lacking full profile inserts. As you thread the pin in the top makes a lovely circle about 30 or 40 thou out.

The offending pin. Still no idea how the threads got cut crooked. Ended up cutting them undersized with a split die then locating the pin in a counterbore above the female thread. Probably the way it should have been done in the first place. The split cotter Steve.

How it clamps the shaft.

And the assembly, need to make a handle with thread to tighten the clamp but a bolt works for now.

We call that split pin you made a Binder here. I was wondering myself what you were referring to. Crystal clear now. Thanks.
