I can't even remember the name of the company, or what they made.
Seemed to me that these guys were pretty clueless. Management had just
purchased two Tornos cam machines (M-4's IIRC) because they knew some
of their parts could be made on them. The machines had been sitting
there for 6 mos. or more, and nobody had any idea how they worked.
When they discovered that I knew how to set up cam machines, they were
all over me for information. I sort of walked them through an
imaginary set-up, but they had no cams or tooling. Let them know where
to get cams, collets, bushings, tools, etc., and they even talked
about having me fly up there for a few days training, but I never
heard from them again.
I remember now, that wasn't 1985. It was the beginning of 1987, which
was when I left Star. Guess that's why I never heard from them
That was back in XT days. Couldn't tell you if they even owned a
computer, and IIRC, CAD for the general user was futuristic.
They did want to know if they could cut their own cams:-/
Sure you can, but don't use that pedestal grinder.
BTW, not trying to be nit picky, but you use a 6.5mm wrench on the
When I was an electrical contractor I actually got pretty good at hand
grinding drills. I used to do maybe 6 full fractional indexes at a time.
Once I was at a customers site and they were cussing about not being able to
drill some holes in structural steel. I looked at their drill bits then
sharpened up a hand full. Every time I'd go back there they'd have a box of
drills waiting for me!

BB, I bought the SRD in 1975 because they had a left hand attachment
for my screw machine spots & drills, even if your good at hand
grinding drills try a left hand one. (screws up your mind).
It's a good grinder but I just use it now-A-days for spot drills.
Matter of fact I just remembered I have 6 3/4" 90 deg spots to grind
was putting it off, you blew my Sunday <G>.
The Darex is an M4 (the one with two wheels) & it's nice in that I can
grind any angle & do flat bottom drills on it. The split point is done
on the right side. I don't think they make them anymore, I bought it
in 1979. It's not that easy to use until you re-mark all the dials to
where they should be. It like the SRD goes to 3/4".
Gee BB I'm lazy er than you I don't bother with anything under 1/4" &
like you just buy a 10 pack. I have done 3/16 drills into a flat
bottom only because I couldn't buy them.
Thats funny. I learned to sharpen Left Hand drills. Twist drills, and
Half Rounds. I can make a little left hand drill look like new. But to
this day, I cannot get a good point on a Right Hand drill:-)
Might have something to do with the fact that I'm Left handed. And I
use an Agathon type tool grinder w/diamond wheels, where you grind on
the side of the wheels. Using the left side of the wheel, and turning
the drill in a counter clockwise direction is a natural movement.
Using the right side of the wheel, and turning the drill in a
clockwise direction is something I just can't seem to do smoothly. Not
too bad with a small drill that I can spin in my fingers, but I have a
lot of trouble with larger drills where I actually have to turn my
wrist. Always come out uneven and don't cut well. So I don't even
Lazy? No, no, no. You've got to use the correct "business-impact
language". We're not being lazy, we're being "Energy and Human
Drills under 3/16" run about $1.00 each on average. It takes about a
minute to walk to and from the drill grinder, another couple of minutes
to actually fit the drill, grind, and split point it. Now if your shop
rate is $60 per hour, that's a dollar per minute. So you've spent a
minimum of $3.00 in time resharpening a $1.00 drill (with probably
slightly less quality that a new one), AND taking time away from other
more important shop activities like setting up or programming the next
Sooooo, lazy doesn't enter into the equation. We are engaging in new
paradigms of value added synergistic infrastructure transitions and
orchestrating optimal profit-oriented stratigizing schemas.
Nawww. I'm just a job-shop rat, we're not into any of those systems
of managerial double-speak. It was just something I cobbled together
this morning when I woke up. Sounded better than "too lazy to grind
small drills" though, didn't it? LOL
I see a bright future in management for you. Anyone that can use
that many buzz words in a single sentence is destined to be a CEO at
Not wishing that on you by any means though. (Been there done that, got
the pre-frontal lobotomy to prove it. MGMT. Not CEO)
