For my education, can you give me some examples of when you use it?I use my lantern/Armstrong/American tool post all the time!
Thanks for this. I'm curious though; why does he feed from the centre of the work?The lantern post holds the Armstrong style tool holders (Circled one in red below), looks like you have several. For the quick change style, you will need other cutting bits. I also like the Armstrong style, as you can use small bits of high speed steel, and custom grind them for your needs. I also found a link to a Tubilcain video that shows them in action.
Hmmm, looks like a Starrett No. 104 speed indicator hiding way down in that box o’ dust as well! Could be a 107, can’t see the handle clear enough. Speed indicator, old style.

That allows me to custom grind a 1/4" tool targeted at the material in question.
I have wondered this too. When the gear train is turning forward that is the direction it goes. In my experience, pushing into the work takes much more force than pulling out does. Tool life and surface finish are better when working from the center out. It always seemed to me that if pushing in was the way to go they would have added another gear in the cross feed chain to go that way when the reversing gears are set to "forward".Thanks for this.
