Re: Cross feed lever modification
Yeah, got it free and ended up trading a Delta stand for this Baldor stand to a guy with just the opposite mismatch! All cleaned up and painted, need to make an intermediate adaptor plate and cover for the switch plate hole.? Cabinet is full of air rifles, mostly.? Dividing head on my bench came from the same place as the grinder,? I really need a milling machine! Dave?

Tony,
grinding HSS can be easy or hard. Generally, if you have a
store-bought grinder it comes with the cheapest of the cheap
Aluminum Oxide wheels (brown or gray). Those are hard wheels
that load up quickly and heat up your HSS tool. These wheels are
best suited for normal carbon steel tools like chisels and such,
not so much for HSS. That being said, you can upgrade your
wheels for not a lot of money to a better wheel (white, for
instance) or even CBN (much pricier). The grades they come in
are usually about 40 (coarse) and 60 (less coarse). You can also
get 80 (fine) and 100 (finer). Some manufacturers go as high as
180 grit. The finer the wheel, the longer you have to grind at
it.?
Before you spend money on new wheels, look at their grinding
surface. If it has lots of shiny areas, your wheel is loaded up
and needs dressing. That alone, will increase your performance
and enjoyment. You need a diamond dresser or a wheel dressing
stick. That will fix up the wheel and restore its performance.?
However, that is not a permanent fix. A better solution is to
get the right wheel for your application. The general rule is to
use a hard wheel for soft grinding and a softer wheel for hard
steel grinding.?
Without going in too deep, the grinder wheels are marked for
Material, Coarseness and Hardness.?
Material can be AlOx, Silicon Carbide, Alumina Ceramic, CBN. For
HSS grinding you want Aluminum Oxide or Ceramic Alumina, or CBN.
Silicon carbide does not work that well on HSS bits. Aluminum
Oxide wheels will be the easiest to find. They cost about 20-25%
more than the cheesy stuff from home depot, but are ideal for
your application.?
Next is Coarseness Grade. Four roughing out a tool bit you want
something around 36-40 grit. The rougher grits will cut faster,
with less heating. After roughing it out you want to use a 60-80
grit wheel to refine the grind. If you have a 100, then you can
refine it further. On the CBN side, you can go to 360 grit.?
Next is Hardness. A softer bonding material for the wheel, will
allow it to break down easier, uncovering fresh new abrasive
grains that are sharp and will bite into your HSS bit faster,
better, and with less heat.??Anyway, here, on any wheel other
than CBN, the grade you want to pick is a soft one: B, D, E or
F. B is softer than F
So, to summarize my
ramblings: Get an Aluminum Oxide wheel, Soft grade B, D,
preferably, or E, F otherwise. With a grit in the 30-36 range.
Also, buy a wheel dresser diamond or a wheel dressing stick
and maintain your wheel regularly (I would do it before each
session of HSS grinding and during, if you notice and
shininess or loading).?
I hate to shape a new cutting tool since there is so much
material to grind away. I would like you forum members to tell
me which wheel you use or which is the most aggressive. My old
cutters are ground for my lantern tool post a couple are still
usable but most need to be deep sixed.

As a follow-up, , Tom Lipton is using a cutoff wheel to hog off chunks of HSS when making a trepanning tool -- following up with clean-up on the bench grinder.

Tony:
If you are removing a lot of material, you may consider using a metal cutting wheel on an angle grinder, or even on a Dremel, depending on the shank size.??
Then you can follow that with an AOx or CBN wheel on your pedestal grinder or a mounted point on your Dremel, with a final hone on a sharpening stone or diamond hone.

I believe 60grit is pretty common for grinding tools.? I've used 120grit when on parting tools because I'm still green in grinding bits and figure if I screw up, might as well screw up less with a less aggressive wheel.? LOL.
But I would thing 60grit should do the job.? Keep the water nearby. -Jody

Re: Cross feed lever modification
BTW, based upon an Atlas price list dated 01 Feb 1966 that I just acquired, we need to back up the introduction date of the 3985, 3986, 3995 and 3996 to at least Jan, 1966. ? Also, if you study the illustrated parts lists for the 3991 and the 3996, you will see that the apron itself is a different part number.? The shaft that fits into the gear that drives the gear on the cross feed screw is different, and has a bushing that looks like it was installed on the shaft before the shaft was peened into the gear.? This bushing is not shown on the 3991 list.? I don’t know whether it wasn’t there or was omitted from the list. ?
