TBI machines was "Re: CNC screw machine mod"

Peter,

TBI, Thomas(?) Brothers Inc.

After looking at my Hardinge collet book I think the collet was a 215
with 1.75" capacity. The 315 is way too large.

Note, that these machines are usually listed as chuckers which
implies no tailstock. The machine I saw did have a tailstock.

Walker Machinery (formerly Rosemead Machinery) in LA usually has one
on the floor.

Made in LA. Sort of like a Hardinge CNC, only a little beefier I
think.
