This writer talks about an "inline speed control" for a grinder.

Does anyone know what he is talking about? What should I buy to set this up for my Craftsman grinder? I need lower speeds for my lathe tools.

Thanks,

Mike

Though I don't know for sure, I would think it is an inline switch to
slow or speed up the grinder/grinding speed, similar to a dimmer
switch for a light. If they (in the link) suspect the Craftsman is
adaptable for one, you might ask at Sears what it is and/or if it's
available.

Only "universal" motors can have speed control of the "dimmer-switch"
type. Those with a capacitor, the more usual motors fitted to grinders
etc, cannot be varied in speed. If a manufacturer has built a speed
control into a machine it is, of course, going to work fine.

The Craftsman quotes a 1/6th hp motor - forget it. The moment you start
trying to grind something it'll slow right down

Stay away from dimmer switches. Motor variometers are much better choice.
I don't know that your motor can handle variable speed.

If you bought a 3450 grinder too bad. Way too fast. Even 1725-1750 in my
mind is too fast.

If you have a grinder 3450, get a set of pillow blocks, and sheaves and
step down the speed. Remount the stone on the new shaft Use a sheave
like used on drill presses so you can adjust your speed.

I have a variable speed grinder. I turned it down once just to see what it
would be like. Turned it back up and left it there.

I bought one of these:

It's impossible to overheat a tool on the slow running wetstone but rather
time consuming if you've anything more than a light "touch-up" to perform.

I use a 1725 rpm grinder with a coarse white friable alox wheel.
Haven't burned a tool yet. I don't even use a water dip.

Or use a smaller wheel. Halving the diameter has the same
effect as halving the speed.

I've been grinding my lathe tools on a high speed grinder for 40 years,
no problemo. I am not alone, and I'm not [all that] special. The wheel
density/make up has a lot to do with how quickly things heat up.
Perhaps a different choice of wheels is in order?

Or maybe just learning how to use the tools without looking for magic
tricks. Sometimes you just have to learn - and not rely on something that
will eliminate that requirement.

It's really getting harder and harder to see people looking for shortcuts
simply because they just won't invest the time.

I'm a fan of buying the right tool for the job. Sometimes, there can be
modifications that can be done safely, and the results are within
parameters. And sometimes performance and safety suffer. Not to mention
the user.

Density, composition, and binder. Coarse white alox, vitrified
bond cuts fast. Vitrified bond means dull grains break off
the wheel, making it essentially self-dressing.

A common in line speed control is one sold to slow down routers. You
plug into the speed control and dial the speed you want.


Keep in mind yo need a different type speed control for a universal
motor, one with brushes, than one that works with a capacitor start
motor, those found on larger more stationary equipment.

I haven't heard of any that would work on this type of motor. For a
motor with brushes, such as a drill, router etc there are speed
controls available.

Most bench grinders and almost certainly the pictured Craftsman use
induction motors and speed control is not practical. There is little
reason to use anything BUT an induction motor on a bench grinder UNLESS
it was designed with the intention of having variable speed. The
common speed controls used for routers and other tools with universal
motors will not work with induction motors. Your best bet for the lathe
tools using a regular grinder is frequent dunking of the tool in water.

Thanks for the advice. I'm going to buy that Porter Cable and be happy.

If you haven't bought yet, consider one of these.

http://www.woodcraft.com/Product/208...d-Grinder.aspx

I have two, and love them both. First, while not variable, they are
slow speed grinders. Second, and probably just as important, they
come with white, friable wheels which are much superior to sharpening
tool steel than the old gray wheels.

They cut cooler, faster, and with less bounce on the wheel. These
wheels are the best for your lathe tools and cost about $25 each for
the 6" size, and about $35 for the 8" size. Surfacing them on
occasion to keep them clean, mine have lasted for years.

If you buy the 6" grinder, then buy the right wheels, you are at the
same price as this grinder. The Woodcraft boys told me they have kept
these around specifically for wood turners and because they have a
great track record. I believe it; one of mine is 14 years old and
still working fine!

Robert

Those were just on sale last month too. I believe 80 some odd ..

I did see this in Woodcraft. That price is a little high. Also, I'd like to have a grinder set up to do other things that need a higher speed (axe, mower blade, &c), and so a variable speed is probably better for me.

Thanks,

Mike

FWIW - and I know this defies the current conventional wisdom... Variable
speed is not necessary. Learn to develop the touch for the material you are
grinding, and you can do it all on a single speed grinder. Don't say that
it can't be done - many of us have developed that knack over the years,
before the variable speed crap came along. It's really not all that
difficult. Sometimes it is really worth the effort to learn to just do it
properly, rather than looking for gadgetry to do the work for you.

That's what I've been doing for the last few years. I can get my lathe tools pretty sharp on the regular grinder, but I've also made mistakes.

Mike

That's it in a nut shell.
