Very nice, Mike!

Crazy skills! Let's see an overall view, Mike. I want to see what you did with the front face. Does it press on, or is it keyed, or what?

The face and detail work is tomorrow or Sundays project. I wanted to get the v-grooves done before I spent too much time making it pretty.

It will be keyed (1" shaft w/ 1/8" key), but I don't have a 1/8" broach right now. I'm going to see if one of the local shops I use for work has one, if not I'll buy one.

In the final episode of our three part mini series - "As the Pulley Turns"

I did a little detail work on the sides while it was still in the lathe.

Then setup the rotary table in the mill.

And setup the pulley on the rotary table.

Then just cut away everything that isn't a pulley.

Do a little deburring and hit it with some scotchbrite this is what's left.

On the motor. I have to put an idler pulley up around that left button head bolt, that's for tomorrow.

Mike, it's a work of art, for sure! I'm not sure I've ever seen a keyed crank pulley made from aluminum, though. All I've ever bought or used were steel, but I'm probably wrong. Either way, great job!

Nice job ! It came out sweet!

I had to add an idler to the mix to get it all to work. The power steering and alternator bracket is a purchased part and I decided to just modify it. It's already overly complicated and too many parts, but I added more pieces to it.

I added an angled piece to help support the pulley and used some b7 all thread and made a nut/ pulley locator.

That holds the pulley just fine.

Instead of keying the crank pulley I decided to convert it all over to pin drive. Each pulley has a set of pressed in 1/4" dowel pins and two slip fit holes on the other side. The mandrel has two pressed in pins and the nut on the end has two slip fit holes. It all stacks up together. This will not have any issues, it's solid.

All finished. Gotta find a belt that fits. If you are wondering how the belt is tensioned, the power steering pump has a jack screw underneath it to move it up to tension the belt.
