    It's been a long week but I managed to find a little time to tinker tonight. First I had to make a thread boring bar for my lathe so I could cut the 15/16"-20 UNEF autococker threads into this body. Once the threading bar was complete, I had to spend some time chucking up and then dialing in the body on my engine lathe. In case you missed it, I decided to single point cut the threads for the barrel instead of spending money on a tap that I will only ever use once.

    Here's some photos of the process along with some video. First the thread boring bar that I made followed by a photo of my Freak barrel screwed into the finished thread while it was still chucked up on my lathe. Lastly is a photo of the current project assembled and in it's current state. At the tail end I have posted some video of the setup and secondly of the threads being cut... I'm beat and off to bed!

    Cheers!

    The Freak barrel (and all my others) fit nicely...

    Still need a few pieces but I'm still making progress. Slow progress but progress none-the-less...

    I managed to buy a clamping feedneck and measure the thread pitch so I could make my press fit feed tube. One more thing scratched off the list...

    Assembled but still missing a cocking rod and beavertail. Almost there!

    Update : I haven't given up!! Life has gotten busy but I'm currently in the market for a reasonably priced paintball hone.

    Stay tuned...

    What is "reasonably priced" in your mind? the only ones I've ever found that were for paintball are the flex hones from BRM.

    Well, marketing something "paintball" is a convenient way to up charge it. Atleast, in my mind it is. I'm a journeyman tool & die maker by trade and have been working within machine shops for over 20 years. Hones are available in the 0.68" diameter range by different manufacturers and different types none of which are tagged for paintball and they come with different price tags. To be honest, for a one time use, I was actually hoping to find somebody who is selling a used adjustable cylinder hone style unit. Obviously thats a best case scenario and very much unlikely. If I can't find a used one for a good price, I'll just end up ordering one from a tool supplier.

    You're right though, in regards to "paintball" hones, the number of vendors is quite limited!

    Here is an example of a cylinder hone which isn't tagged as a "paintball" hone: https://www.mcmaster.com/6713a21
