Looks great Mike. So, how close is this to being on the road?

[MeanMike]

Still a long way. I'm only getting one day a week to work on it. I still have to run fuel line (stainless hard line), make a crank pulley, fix a coolant leak around my belt drive, rework my intercooler charge tubes, wire most everything, shorten my driveshaft, fill and bleed all fluids, alignment, hang the exhaust and build a new air intake and filter box. Hopefully it will be done before spring is here, but I'm not rushing it.

lol... I hate it when I start making lists like that and they keep going and going and going...

Interior looks good, keep on plugging along and you'll be done soon at the rate you work.

Yes, the list. I get one thing done and add two more to the list. But you know you are close when you get summit gift cards for Christmas and can't figure out what to buy.

I really didn't want to work on the trunk today, so I started on my crank pulley instead.

I had a V-belt on it before with just an alternator. To use the Turbo Buick power steering pump, I had to switch to a 6 rib belt. I could only find one place that made a 1" mandrel driven 6" 6 rib belt. It wasn't exactly what I wanted and they think a lot of them, so I figured I would just make it myself.



I have a piece of 1" x 6" flat bar that will work. If I had a 6" round piece that might have been better, but I used what I had.



First bore the 1" ID in it, so I can fixture there and build off that centerline. Drilled it 7/8" and then bored to size with a boring bar.





The I found a piece of 1.5" scrap to build a mandrel out of.



I roughted out the OD in the bandsaw and mill and started turning.



Finshed to size. 6.000" OD.

I found K sized serpentine belt dimensions online. They use a 40* angle, so I had to grind my own cutter.

Then I cut the grooves. This was a little nerve racking because that's a lot of chip load on a really thin (brittle) carbide tool.

That's just showing off...

Very unique, good looking car, can't wait to see it on the road.
You have some great fab skills.

[WSSix]

Very nice, Mike!

[Che70velle]

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?
