Ok, so my cam is done except for the swage on the cable loop. My plan is to go to Lowes or Home Depot tomorrow so I can borrow a swaging tool to crimp it in the store then to send it in to Aric USPS Priority to get it there by Wednesday. Here is a preview of the cam:

Utah Custom Hardware Extraterrestrial

-External Cam Springs allow a much more compact camming unit. With this system, Extraterrestrials fit into smaller placements and have more cam surface area per width than other units.

-Nylon trigger wire protection sheath allows true flexibility of the main cable stem AND solid cam control. Cam walk and placement change are minimized. Deeper placements are possible, but don't place the stem over sharp edges or so that permanent bending or damage will occur when the unit is weighted.

-Secure grip and control. Easy clipping and racking are provided by the cable loop. Extraterrestrials come with a sewn nylon runner.

-Axles are a .25" grade 8 steel bolt. Also. the Internal Spring system allows the axle length to be minimized, which results in a short and virtually unbendable axle.

-Cams are machined from 6061-T6 Aluminum, a grippy alloy with TEETH.

-Moderate cam angle of 16 degrees for greater holding power.

-Sturdy steel handle and top puller are crimped to 1/16" 7x7 galvanized steel trigger wire. A tubular nylon sheath provides trigger wire protection. The sheath can be taped, but don't tape tightly or it will cause drag in the operation.

-Quality connections. The main cable is individually attached 24mm deep to the aluminum cable eye fitting with a newly developed "Bonzing" process. Aluminum cable fittings are used for the swaged connections.

-Quality control. There is none, and I mean absolutely none. If you would like, I will stamp "tested" on any unit that you would like.

-This cam is rated to 46 kN but my guess is that it will fail at around 6kN by mode of the cable pulling from the head.
