Before I introduce this new method to hand cut Mag D like a real lathe, I'd like to review the previous methods briefly.
Method #1. The Neck Grinder
First introduced by Stafan in this thread:
http://www.candlepowerforums.com/vb/showthread.php?227140
This method grind away the thread in the neck & cut mag tube & grind the top narrow to go into the head. This method can also be used to join Mag tube with Dx turbo head, like I've done here in the MagDEFT: http://www.candlepowerforums.com/vb/showthread.php?268894
This method is easiest of the 3, but with a big flaw: It lost the mag focus function.
Method #2. The Belly Cutter
First introduced by me in this thread:

Did it again here & got better with practice:

The concept is simple: Cut in the belly to remove unwanted section, The two keeper sections, one bore out the end & one grind away the end until one end can plug into the other. For the D mag tube, some practice is necessary as it's not easy to match the seam.
Method #2 has the advantage over #1 as it retains the mag focus function ( it doesn't touch the neck). But it also has a flaw: The belly scar, it can be hidden at the curled/uncurled junction but it's still there.
Now, I am introducing a New Innovation &the best cutting method:
Method #3: The Human Lathe :devil:
This method is done similar to real lathe, ie. cut the tube and re-thread the end.
Step 1. Cut the tube and bore the end. See link in method #2 for how to bore it with a drill attached bit Rotary File. Except that I now tie the drill down on the table so I can do the bore by two hands, don't have to hold-down the drill greatly increased the stability and accuracy of hand operation.
It has to be bored almost open, note the thin layer, only 0.5mm tube remain:
Step two: Surgically retrieve the thread: Basically, cut the threaded section out and grind the outer surface to as thin as possible without grind through the tube
Look how thin it is, less than 0.5mm
Step 3: Plug em in:
Plugged-in half way, so you can see. Apply JB weld in 3-4 locations & push all the way in.
Grind the end smooth with a file first followed by knife grinding stone to machine smooth.
View from the end after finishing the thread translocation. You can see the spit seam in the middle of the tube wall, the wall is the thinnest in this area & there's very little room for error.
Done! If I haven't just told you, can you tell its done by Human Lathe or metal Lathe?
Finished host. My Mag 1D Turbo head next to Mag 2C. The neck section is the neck from DX shower head host joined to mag body using Belly Cutter technique, method #2 above. This way, I can still do focusing & also allow room for a big copper heat sink with the elongated neck decorated with Carbon Fiber.
