Hi Steve
Yes you have to stop the mill every time you need to increase the diameter of the cut. in this case I was taking small cuts due to the cut being intermitant ,and the out of balance of the head.

way back in post 1053 I posted a picture of a sheave that I made and John aka doubleboost asked how I cut the key way, well I decided to also change the one on the motor spindle so when I broached the keyway I just happened to have the camera with me.

so here's a shot of how I broached the keyway. And can anyone tell me the name of that high pressure green lube I have swabbed on the broach, I know it comes in a white plastic jar.

It's probably extreme pressure grease made by this company. I have a tube of it. It's commonly used on dead centers and available from McMaster.

I would like to see some more details on your broaching tool. I assume you made that?

Thanks,

The reason I ask is because I no longer have access to the lovely Narex boring I had at work (it had a facing feature!) .
I had to devise my own for a cylinder head machining story I'll explain later to anyone interested.
Long and short is, I built the following device to advance the tool with every revolution.     I cut a new feed screw (7/16-20) and fitted a # 25. sprocket.


It worked great! I was able to bore the head to compensate for the "overstroke" I had given the crank.
    Then I built a bracket to clamp on the quill of my Tree mill.
   
On the bracket I added a "tooth" that would advance the sprocket one tooth. I made it so as I could lift it out of the pathof the sprocket and therefore not advance the tool.

Sorry for the jumbled pics and text. My head hurts and I'm now soothing it with another homemade brew.

I'd be interested in that "cylinder head machining story".

Neat advance mechanism Steve. You crafty old bugger.

Not the broach. The broaching tool. The blue thing.
