Re: wood lathe fall away tail stock

['Curt George' via Legacy Ornamental Mills]

 I just re-watched your video.
Very nice.  I am glad it works well. It is a pretty neat idea.
Use what works! And if it doesn't, Make it work!  ;-)

Very easy you can do it easy with one finger the jig is spring assisted you can 
see the spring on the right hand side if you look closely

As the video is playing also lowering it you can see I’m only using just my 
fingers on one hand

Hey Bill

  

I like that! Good job on this one.

  

How much weight is that device? (I mean how much weight is the tailstock 
tilting?) is it easy to move?

Looks Awesome.

  

thank you for sharing.

Ok this is not legacy but I promised a few of the guys privately a short video 
of my fall away tail stock. Its such a good idea I thought I would

Share it with everyone I like this type the best because it swings down and 
away leaving lots of room to slide other things that hang out like

Steady rests which are difficult with ones that just hinge out sideways

Re: Oval jig video

[cdkr...@gmail.com]

That's a relatively old technique of approximation.  I learned about that 
studying to do drafting of engineering drawings in the late 1950's.  I've 
seen that video posted on metal working sites I follow.  Didn't get me
excited.  I'm chasing Curt's shiny object in my head thinking how to 
squash it flat.  I'm attracted to the wide array of options that the 
sun-planet
gear arrangement offers, and the notion is compatible with the gear making
equipment used to make driver, duplex, and index gearing for the LOM. 

For example, if the planet-sun gear chain opens up to include "idler" gears
between, then the options for greater range of ratios and direction open. 
The notion of using a tiny chain system is doable, but limiting a bit, e.g.
change of direction.  Curt's "toy", an ornamental chuck, is an advanced
concept of this application. 

So how much gearing can be squashed into 3/8" vertical space under a
table constrained to linear movement as it rotates on another platform?
Any clock makers in the group?
