Wow. I can't even think of a snappy line here. LOL.
I almost brought home an Emco Maier training lathe once. One of those
little CNC deals that the hobby guys are wild about. A customer told me
that if I wanted it I could take it. Had I known about your closet I
could have UPS'd it out to you. All you'd need is a table top surface
grinder and you'd be stylin'...
If I cant fine them then Ill bore the headstock out X 5mm else breakdown and
machine a more robust one from solid.
I which case might well mass produce several thousand along with spindle
proper before my retirement...
Funny thing...for so many years I was looking for work...."things to make",
you know the drill--buying tools tooling scraping up some work make damned
Dan I live a fairly simple life mostly drive a beat up '86 blazer, ( the
commute is a killer ) love to make soup and cook in general hopefully will
be growing a bigger garden this year I bake bread make my own beer and even
started growing the hops again this year and so forth...
Hard to explain, in a nutshell not lacking here for "things to make" car
parts gun parts parts for model hobby folk job shop whatever make a new
tractor pin for a six pak I guess its gotta make a lil bit of money without
stiffing somebody else, and has to be fun or at least low stress..

Looks like press a ring into the headstock bore to reduce dia by 5mm and use
duplex set of 2mm7911 ( 7010 ) and fab a new spacer to suit.
And at the drive end screw it Ill just toss in a 6010 standard radial
bearing and as before, fab anew linear spacer ...
Well, I never got around to fixing the tractor today....
And thanks for the input on that swiss machine its much appreciated.
Well its officially mine will pick it up later this week went and surveyed
the situation this afternoon, live tools available all 10 station ( no live
holders included 2 straight holders is all ) 1 deg indexing, no bush or bush
holder and when the machine boots the x runs away to end of stroke then puts
out an err code--known history is someone rebuilt both motors, end cap on x
motor is loose so I say look at ref sig at amp doublecheck resolver and tach
connections go from there.
Cool. So I take it that the MB is OK?
Once you get the servo sorted out the old "P" "CAN" trick will get rid of
the grid shift and allow you to zero return the X-axis.
IIRC, zero in "X" puts the cut off tool at X-0.08" or maybe it's X-
0.060". It's been a long time. Anyway you need to set up the coordinate
system with a G50. I doubt that it has geometry offsets so for milling
tools and tools that stick out beyond standard tool point you use G50
with a "U" or "W" to shift the coordinate system incrementally. It also
uses mirror image for the two turrets. G68 tuns it on G69 turns it off.
You always program the rear turret as though it is the front as far as
circular interpolation and TNRC.
Well get it running first and I'll be happy to get you oriented on the
You can pick up used live tools and driven bushings here -
Ask for Steve and tell him you're a friend and I said no prison love.
Or keep an eye on Ebay. I see stuff for them on there from time to time.
Either way you'll end up paying more for the missing stuff than the
machine given the good deal and all.
My dad came upon an opportunity some 10 years ago to CNC
machine some small parts for a local company. Dad's no
machinist but a hell of a technical guy. I converted a
Sherline mill to CNC running the AHHA software and devised
an approach to fixturing that worked very well. Though he
still can barely copy a file from a floppy to a HDD (he's
nearly 80 now and just will never be comfortable with
computers), he did pick up the process and ended up with the
lowest reject rate of any of the shops supplying this
company. He was going up against shops with the real stuff
and held his own. A comparator and toolmaker's microscope
verified we were holding parts to +/-.001 or better. Dad was
knocking down upwards of $60k/year right up until the
company was bought out and machining was brought in house.
Parts made on that Sherline are flying in Boeing aircraft,
used in Bradley fighting vehicles, and many other critical

company and the pictured elements are what he machined. Very
possible all the parts pictured were machined by him.
