hello,

yeah i would imagine their would be some inacuracy in tool paths, i plan on going for many slots on the encoder just not sure how many i nead, i can always experiment wih this.

i'm not building it with anything perticular in mind it's just i cant have another lathe sitting around :) (i have my first lathe on a shelf in the bedroom it's a piece of art and i'm a bit attached to it)

at the moment I'm aiming highh and seing how far it can go :)

even if i end up with not as much capability as I would like it will be an interesting journey.

A mostly flat surface could be handy for easy finishing on a mill for example. Less nead to index part for hex heads for example.

thanks for the input I am taking it all in and i prommis i'm not going to try and run before i walk and all that.
