There isn't too much here, but a few things.

Freak Reball Insert:
I made this back when SP first had the idea to release out a limited batch of stainless steel reball inserts in April 2006. I tried my hand with an aluminum version instead, with 0.670" inside diameter, length 5.060", outside diameter of 0.745". I didn't turn the outside diameter, rather just used 3/4" material and sanded it down.

I didn't anodize it or anything, just left it raw. As a result of that it got pretty banged up on the inside.

As stated, SP did a limited run of these back in mid 2006 but they were all sold out instantly, so there isn't really a source for them right now (at the time of this writing).

Modded Freak Barrel:
Common modification, this one involving an old Shocker All American barrel back which I bored out to hold a Freak insert. I placed one o-ring groove in the rear of the barrel and let the insert hold itself inside the lip of the barrel front (Freak backs normally have two o-rings). I also had to bore out the front of the barrel and re-tap it to screw onto the front, because Freak barrels are a little shorter than All Americans. It was my first time tapping internal threads on this junk chinese lathe, but it worked out okay this time (after I did a few practice pieces).

Freak-to-Autococker front adapter:
This was a custom project I built for a friend of mine. He wanted to use one of his Autococker barrels as the "front" section for his Superfreak system. To accomplish this, I built a barrel adapter for him which had male Freak/AA threads on the rear, and female Autococker threads on the front.

The adapter was made in two setups, first the outside was created on a CNC lathe, then the inside was drilled and bored out on a traditional lathe. I performed the outside cuts then handed the part off to my friend who finished up the inside.

Above you can see the finished adapter, and a silly picture where I installed it on a blue Strange Shocker with a 2002 Freak back leading into a Superfreak back leading into a 10" Freak front. This is NOT how the barrel is intended to be used; I simply thought the picture would be funny. The barrel adapter is actually used on a Superfreak back leading into a 6" stubby barrel fitted with an Apex tip, installed on a BT TM15 marker.
