I would like to know if anyone else has tried out the model 500 or 750
Drill Doctor sharpened by Darex.

Anything good or bad to say?

>Drill Doctor sharpened by Darex.

I have the 500. It is good but... The thingy for setting the drill in the
proper position leaves a little to be desired. It has two balde-like
fingers that grip the front and back of the flutes. Providing the drill
has not been severely relieved (as some DeWalt drills are) it does a good
jopb of aligining the drill.

However for smaller drills, 1/4 or less it is a bit of trial and error to
get the correct clearance angle behind the cutting edge. Short drills are
interesting to set up too. I use a lot of screw machine length drills and
just use the device to set the depth then I guess visually where the
cutting edges should be. Practice has it fairly well controlled now.

It sharpens really well and splits points very well. Providing you can
live with the setup system it is a fine addition to the workshop. I'm
hoping Darex will come up with an alternative to the current setup.
Someone recently suggested a visual setting tool in place of the current
one. This sounded to be along the lines of the way I do it by eye.

Given all of this it is still *way* better than any other sharpener I have
used costing less than $300. It is also infinitely better than sharpening
by hand.

>Anything good or bad to say?

good unit for the price... some problems most covered and corected here...
If you search DejaNews (esp the sept /oct time frame when many of us got
one  you will find several reviews/problems and fixes...

for those of us who got in on the free wheel deal a few thoughts on using
it:

BTW I just got my free spare Diamond wheel from Darax (thanks Mr. anderson
Merry Xmas to you too) and I have been thinking of mounting it on an arbor
and turning it at slow speed (on the lathe or mill) to get a Glendo
Acugrind effect... for touching up Carbide inserts when they chip (for a
lot of use they dont have to be indexable so loosing the exact center to
cutting edge comonality is no big deal) small tilting table in the lathe
tool holder and speed about 300 rpm...

also a bit more thinking on a related subject... Low speed grinding with
diamond wheels... someone mentioned a cheap source for the aprox 6" flat
diamond plates (and ceramic laps charged withthe diamond slurry) as a
jewelery supply house... the one I tryed (rio) was just as expensive as
Glendo... but if you could get these for a reasonable price mounting them
on a lathe with a simple home made tilt table clamped to the ways would be
a very cheap way to get the full effect of the $700 glendo acugrind... does
anyone know exactly the speed to run these slow soeed diamond wheels at> I
am guessing 300 to 400 rpm...

I will prob just make an adapter so that I can mount one of low speed
diamond laps to (when I find one cheap)  by baldor carbide grinder to try
this out as it already has a 3 phase motor and I run it (and all my 3 phase
tools) through the Mutsibishi Freqrol... hence I can just command the speed
for it spin but for folks who don't want to go to the trouble of making a
slow speed grinder from scratch making a mounting plat to fit their lathe
and making a quick table that will hit close to the wheel just above the
middle (as seen in the glendo adds) should be a doddle... if any one does
the lathe method let us know please... perhaps I sould try it my self and
write it up for the tips section of HSM or MEW?

Go to http://www.drilldr.com/ and see/read all about it. I have been
thinking about getting one myself, but would like to hear some more
comments before I shell out the dough.

Thanks, I took a look and found about 100 articles. Seemed to be an
initial problem with alignment on 3/8 and smaller bits and with the
amount of relief. Has these problems been corrected to everyone's
satisfaction?

I know we talked a lot about the Drill DR. a month or so ago, I guess 
some folks would still like to hear how  well the sharpener is working.  
This is my little experience with the 3/4 inch sharpener so far. I have 
only sharpened about 45 to 50 drills 3/32" to 3/4" in size.  The machine 
has worked great the first 10 to 15 drills the point seems a little rough 
but after that the points are showing much more polish. The holes I have 
drilled are round and close tolerance. My personal opinion is that it is 
a quality tool.

That is a neat idea.  Especially since I am luckey enough to
have two lathes and could easily set it up on the one not
being used at the moment.  (I have had the mill, shaper, and
one lathe operational at the same time, but *never* two
lathes).  I will have to get out the yellow pages and look
up lapidary shops.  There must be some in the SanFernando
Valley.

Does anybody happen to know if there are any there that have
these diamond laps?

Try the crystalite corporation
1-800-777-2894

they have a neat catalog of lapidary/glass diamond wheels, laps, hones
flexible belts, burs core drills etc. They also have diamond powder and 
compound. Many dealers carry their products at a savings (or a premium, caveat 
emptor)

No .. but practise makes perfect and you can do a pretty good job with
it.

I, too, wanted to see more comments, but with so many positive ones
over the past months, I finally got one and am very glad I did.  The
results are SOOO much better than the B&D piece of junk I was using.

One word of caution.  The instructions say this, but IMHO it should be
in bold with arrows and flashing lights, it is too easily overlooked
and it is *critical*.  It says that when sharpening, you should turn
and *lightly* push.  That is very true.  What it does not say is that
if you push too hard, what you get is a bit profile that looks
*nothing* like what it should,  in other words, by pushing too hard,
it is possible to ruin the drill bit.  However, you can just as easily
go back and do it right, and save the drill in a matter of a minute or
so.

So far in the couple of dozen bits I have sharpened, this seems to be
the only shortcoming of the machine.  IMHO, it should be made such
that the operator's *touch* cannot effect the end result, but maybe
that was too much of an engineering feat for a machine at this price
as opposed to Darex's other drill grinding machines.  But, once you do
get the right touch, you can produce an outstanding result.

Not as far as I am aware. I still use the trial and error visual method.
Still better than sharpening by hand though.

I have had a chance to sharpen a few handfulls of bits with mine
and the standard point comes out very nice. The 135 split point
I havent got quite figured out yet. It's not quite equal on the 
two sides, but I only tried it once so when I get time to figure
out what I did wrong it'll probably be fine also.  ...lew...
