Making A Wedge Lock Quick Change Tool Post For The New Lathe

G'day everyone,

Seems to be a tradition at this point that I make a Quick Change Tool Post for the lathe. I have done it twice before, and I was rather hoping that I could continue using the old Compact tool post that I made for the mini lathe. In fairness to it, it works, but once you ramp up the depth of cut and the power feed, it does show a good amount of deflection.

So I thought I would be best to make another one. I could have probably bought one for $200-300 for a good quality one, but where is the fun in that. However I was determined to change the locking mechanism from a plunger style to a moving dovetail. This should be more rigid, and from what I have seen, there isn't any tutorial on how to make a wedge lock, so I might as well throw my hat in to the ring and see what I can come up with.

I also want to keep it as compact as possible to make it easier for filming. My old tool post with the cam lock piston, the handle used to get int he way quite often, hence why I made the compact design. And I will try to keep it compact here too. I hope you enjoy the video.

Lathe: Hafco Al 250g
Red Lathe: Sieg C3 7x14 Mini Lathe
Milling Machine: Sieg X2.7l
