Working on the pedal cranks today\o/ There is only one straight part on this whole thing. So We'll use that to indicate the crank in. Here's my trusty old indicator. I like this one, it has ruby jewels in the side:o)



All indicated in I move to the opposite end of the crank and using a slitting saw cut a slot so the cranks will clamp onto the crank shaft.



This is one of the things that has been taking up some of my time. I put tin on the back of my shop. It was used, but free:o) It will look fine with a fresh coat of paint.



In front, on each side of the big door and rhubarb, there are giant sunflowers planted. I can't wait for them to start growing:o)

Powder Keg:
Crank arms are nearly done:o) Tonight I started by thinning up the end where the pedals attach.



To make it a little fancy I used a ball mill to mill a groove into the back side of the arm.



To set final depth of the groove I just used a piece of paper to set the clearance at the bottom of the cutter.



Then I set the angle that the back side of the arm would be milled to.
I then milled the excess aluminum off:o)



I'll post a picture of the crank arms tomorrow. They are nearly done\o/

Powder Keg:
Thanks Rob:o)

Here is a picture of the crank arms. I still need to clean them up some. I did get the key ways broached. We only had a plug set up for 3/16" keys. That will have to work:o)



I think all I have it to key the shaft and make a couple spacers and the front hub assembly is done\o/
