RE: Picture of my new toy (I think?)

Tim,

The toolholder looks just like the NMTB set that ENCO has on sale, except
this one holds collets.

I'd like to get a set of collets for this holder, but the enco catalog
doesnt sell them w/o a holder.



You're going to need:

- 1/2" socket ( recommend >= 1/2 inch drive) and a long 'breaker bar' for
the head rotation locking bolts.
- socket set
- hex wrenches large assorted


see wwww.Harborfreight.com

Toolholder and quill drive nut on rack/pinion :
- Huge adjustable wrench (Harborfreight.com $19.99) 25' 2.25" inch
capacity or more. for the collet nut
- 1.75" wrench for the holder body while removing the collet nut ( I found
one at a harborfreight store for $9.99)
note: I had to grind the wrench side-of jaws to make it norrower.
- spannerwrench set $14.99 part# 41243-OMBA (harborfreight) I had to grind
the "lip" of the spanner to fit in the
coller slot better.

ps I got a got 7.5 hp 220v 3phase motor and a questionable 10hp 220v 3phase
today for $120.
www.meci.com has the caps needed for the 3phase conversion. and I'll get
the relay from grainger.
Some of the contactors we'll need are in the control unit box at the back
of the mill.
