Really cool project Kevin, looking forward to seeing more progress.

You said this is for school, might be good to spell axle correctly for anything written and submitted for your project.

UPDATE:

Spent yesterday and today cutting out and finishing lobes. Ready to begin cutting holes for axle and lightening holes. Can't find a drillbit that works though, so I might have to use a smaller size one and file out the inside until the lobes are loose on the axle. Ben Hicks- luckily this is the one class that requires zero writing, although thanks for pointing that out. Ben Beard- Thanks! I am really enjoying working on this project and hope to finish in the next week or so. The feedback I have received from everyone on MP has been great.

UPDATE:

After messing up another lobe (lesson learned, go slow) I milled another and got it cut today. After that and a bit of searching, I found a drill bit slightly larger than the axle, and drilled the holes for the lobes to fit on the axle. Tomorrow I plan on working on trigger wire holes and holes for the pin that will hold the spring on.

gun cabinet? shit, we were stuck with making a metal ash tray(before political correctness days).

In the 70's when guys were first admitted to 'home economics' classes like sewing, the Frostline Kits company kept many an outdoor guy busy designing and sewing up either a down vest or jacket, or a sleeping bag in high school. That was worh the project for sure.

UPDATE:

Getting close, got the cam stops/spring pins installed in the lobes today. Just have to add lightening and trigger wire holes and finish the trigger bar them I'm basically done.

This is an awesome project dude, looks like a ton of fun! I am curious though, could you not have gotten a piece of aluminum closer in width to the lobes instead of having to mill off what looks like almost half of a thicker piece? Ian Stewart

This is about the coolest thing I have seen in a while!

When you move on for your engineering degree it will be fun to do some load testing on this in your Mechanics of Materials class...

UPDATE:

Yesterday I added lightening holes and trigger wire holes to the lobes. Geting really close and all the machining that's left to do is to machine a trigger bar. I was originally going to go with a round bar, but attempting to drill small holes in it has broken several bits, so I am going to machine a small flat rectangular bar instead. Will also cut teeth into the lobes on Monday. Ian Stewart- I wish I didn't have to machine so much off, seems like a waste to me, but the plate I ordered was the thickness of the stem, which is what I needed.

UPDATE:

Got the teeth cut into the lobes today and started assembling the cam. Got the upper part of the trigger wires attached and a trigger bar machined. Unfortunantly, the trigger bar was a bit small, so tomorrow I will machine a new one and hopefully finish the cam.

I know the lobes are a bit tweaked, but once I add another washer to each side they should be fine.
