Tailstock Die Holder

For all of those wonderful times when you want to thread, but you are too lazy to switch change gears for the right thread pitch, I give you my version of a tailstock die holder.  Essentially, it is a thread-cutting tool to sit in the tailstock.


Mine was made using 5/8 tool steel road that was drilled for a 3/8-24 thread in one end, and screwed onto an MT2 arbor that was 3/8-24 on it.  Then, a cylindrical piece of aluminum was cut, turned, faced, and bored out, and then some set screw holes put in it.


Mine had a 1.5" hole bored, as well as a 1" hole.  Then, I can use two different types of dies.  Also, it was turned to a 2" diameter so I can use a 2" inner diameter tube and hold a 2" die, too.  It means I can hold the vast majority of dies for easy threading on the lathe!

Starting RMAV (Remotely Manned Arial Vehicle)

I'd wanted to build a quad-copter.  Out of curiosity, I found a carbon fiber frame on a Chinese website for $30, and I ordered it.  I took it into the office (we have a guy that loves anything RC), and he talked about it being just like the one he paid $100 for.  After realizing I had a Chinese knock-off, I decided to keep building.  I'd like to buy one of those $100 frames just so the guy gets credit, but that will come when my wife thinks FPV is cool and takes over mine.  Anyway, here we go.

I think green is cool.  So, I ordered green tubes (I needed 34mm and a 28mm tubes) and green cone washers.  The 34mm tubes didn't come in the size required for the quad frame, so I needed to turn them from 35mm down to 34mm down on the lathe.  Being cheap aluminum, the first one bent.  I chucked up the second one closer to the collet, and was successful :





My quad now has KV2600 T-Motors in green.  Since then, I've added the flight stack, and added some heat shrink tubing to secure the motor wires to the arms.  I've also added green antenna tubes in order to get a little more complete.  My propellers are a 3-blade HQ with a pitch of 4.3.  I know they sell 4.8 for quick response, but I'd like something a tad bit more gentle.



The above picture was taken before the green lock nuts arrived.  As of October 28, 2018, I have picked up an orange RunCam Swift 2 camera, and I removed the case and painted it some random color.


I have also picked up a DX6 (made by Spektrum) to control this thing.  My list of stuff to acquire and put on is :
  • FPV transmitter and Antenna
  • FPV goggles (Fat Shark Dominators)
  • Radio Receiver
  • Batteries and Chargers
Kinda excited to get this thing done.
