Tired of waiting for an aluminum frame run I decide to give it a shot myself. I doubt I’ll get it done for C4, but I’m going to give it a shot.

I have a friend who lent me his time and shop, and this is what we came up with over the weekend.

It’s the shoulder/leg mount, which allows the leg to rotate the 38 degrees from 2 legs to 3 legs.

I figured it was probably the hardest part to make out of the entire frame, so if I couldn’t get his made then there was no point in making anything else.

I think it came out pretty well, but took a lot longer than I thought it would.

Here’s a quick diagram of the frame and it’s various components –

Next up the frame rings.

Big thanks to Jon for the use of his shop and his time showing me the ropes, and to Jerry for allowing me to use his plans.
