Default Lathe Tool Sharpening?

I've had a HF mini-lathe for decades, but never used it much.
Picked up most of a Unimat DB-200.
Got the bug to make the DB-200 mill work.
Prices for Unimat parts are insane. Not gonna spend much
fixing up a $15 DB-200.

I'm at that awkward stage where it would be nice to have a mill
to make parts for a mill.
Couple that with the fact that I have no idea what I'm doing...
I'm an electrical engineer...all this mekanikl stuff is not my forte.
I expect to be working with aluminum and plastic, but steel seems
to be what I need to build the tools to do it.

With the lathe, I'm not so much cutting metal as I'm rubbing it off. ;-)
Been experimenting with sharpening bits by hand, but I no longer have the
manual dexterity to get it straight.

I bought the $4 HF set of carbide tools. Work pretty well
on straight cuts,
but the first thing I want to do is turn a square into a round.
Interrupted cut is not recommended, so I'd rather not break 'em.

I went googling for sharpening methods and found a bewildering
array of tutorials, all suggesting different angles.

I found this site particularly interesting.

http://www.gadgetbuilder.com/LatheBitSharpening.html

In particular, they downplay the importance of back rake. That
simplifies the sharpening process.

And the jig is something I can make with the tools I already have.

Recommendations for a newbie without a lot of machine tools or experience?

This is a hobby. Guiding principles a
Cheap
Simple
Barely good enough is OK.
Build it from stuff you find on the floor in the garage.
Have fun learning stuff.
Did I mention CHEAP?
It's not logical, but I've spent $10 and a week to save a dollar...
and enjoyed every minute of it.

Thanks,
mike

You don't really need any back or much side rake and the front and
side relief angles can be as low as 5 degrees. The advantage of
minimizing these angles is being able to cut brass, aluminum and
steel, the disadvantage is less than optimal cutting rate.

When I grind form tools such as threading, gear and spline cutting
bits in an angle vise on my surface grinder I use 5 degrees for the
side rake and leave the top flat to make measuring the geometry
easier. Since they do cut slowly I rough out the part with bits that
have a more aggressive rake on top.

Mike - like on wood the square to round is nasty to do.

I'd hand grind the 'points' down so the round is almost there
and then turn the final part on the lathe.

Saves lathe parts and uses a cheaper grinder part.

On wood I plane or file down the corners to get the job going.

When you say sharpening bits by hand, I am assuming you mean holding the bit by hand and sharpen using a bench grinder. It really is not that hard to do. I would recommend that you spend a little time practicing. Getting so you can do it is worth the effort.

If you let us know where you are someone might take a little time and show you how they do it. I sharpen drill bit by hand but do not do it as most people do it. I start at the heel and progress to the cutting edge.

Thanks for the input, but that ain't gonna happen.
Knowing how is not my biggest problem.
Manual dexterity has never been my strength. At 66, my hands don't always
go where my brain tells 'em to go.
Trying to cut a compound angle in three dimensions isn't working for me.
I can't hold the bit still enough to grind a flat surface at any angle.
I need to build some simple guides/fixtures to constrain movement
relative to the grinding wheel. Of course, a better grinder would help...


Us old dogs need to stick together...

You need somebody to show you. But i know finding that guy ain't easy.

Barring that, you need something to make it easy. I'd suggest this:
https://www.grizzly.com/products/Hea...-Grinder/H7762

if you go this way, I'd go to using brazed carbide lathe bits and just
sharpen the cutting edge.

These young kids........... I am thirteen years older than you. But I still think you ought to try. You will not get worse.

I kind of roll the piece I am grinding into the wheel. I probably grind three sides and then look at what I have done and try grinding it closer to what I want.

I clamp new lathe bits in the bench vise and rough them out with an
angle grinder. The bit can be tilted to the cutting edge angle you
want so you hold the grinder level, then drop the handle down to the
relief angle instead of trying to guess two angles at once. Whem I
want back or side rake on the top I stand the bit upright and grind it
with the edge of the wheel so I can better see what I'm doing and keep
the cut depth fairly even.

Then I press the bit against the motor housing on the pedestal grinder
as a proxy for the wheel to align the bit to the same angle to finish
grind it. Setting the grinder tool rest to the front/side relief
angle, somewhere between 5 and 10 degrees, helps a lot.

For small [1/4 inch] HSS lathe tools a small belt sander can
be better than a wheel grinder as this eliminates problems
with dressing the wheel. Most have table/fence and you can

Mike , I use the HF 3" grinder that has an orange grindstone on the right
and the "buffing" pad on the left . My rest is set just above
center-of-wheel , and I can hold the lathe bit flat on the rest and get a
pretty decent angle on the sidesand front . It's a cheap unit , around 30
bucks IIRC , and works really well for lathe bits . If you'd like I can
email you a sheet that has angles and all that for several common lathe
cutters .
Heh , I probably got it here !

I have a 4.5" ShopSmith that I've been using for almost 50 years.
Biggest problem with it is that the tool rest is worthless.
I need to fabricate something more adjustable and stable.

I had a nice 6" grinder with much better tool rest.
Never had anywhere to set it up, so I tripped over it on the garage
floor for a decade or more.
Last month, I cleaned up the garage and sold off some stuff I thought
I'd never use...including the grinder.
Same day, I found the box with the Unimat parts and decided to make it work.
I try not to be a hoarder, but I've run out of space.
I rarely need stuff until just after I got rid of it.

Perhaps jig up a cross-slide drill press vise and use it to steady
your hands. Mount it (or the grinder itself?) to a board and use yet
another screw to change Z.

That's a large club , to which I also belong . Toss it today , need it
tomorrrow . This little grinder I use is really small , takes up about 4 by
7 inches of workbench space . I also have an 8" grinder , which I drag out
from under the lathe occasionally to rough new bits . It carries a 3/4" gray
general use stone on one side , and a 1" thick green stone on the other side
for carbides .
Check out the Veritas adjustable rests , adjustable in several directions
and it has a slot you can slide a toolholder in .

wheels and gave it to Junior. He claims that it is in-adequate for his
needs but it does remove metal and doesn't take up much space in his
limited work area. Meanwhile I have a pedestal grinder made from a
double shaft, quarter horse, 1725 RPM motor that I have been using for
50+ years and have no plans to replace.

With the lathe, I'm not so much cutting metal as I'm rubbing it off. ;-)

Been experimenting with sharpening bits by hand, but I no longer have the

manual dexterity to get it straight.





It's not logical, but I've spent $10 and a week to save a dollar...

and enjoyed every minute of it.



Thanks,

When you say sharpening bits by hand, I am assuming you mean holding the bit by hand and sharpen using a bench grinder. It really is not that hard to do. I would recommend that you spend a little time practicing. Getting so you can do it is worth the effort.

If you let us know where you are someone might take a little time and show you how they do it. I sharpen drill bit by hand but do not do it as most people do it. I start at the heel and progress to the cutting edge.

Thanks for the input, but that ain't gonna happen.
Knowing how is not my biggest problem.
Manual dexterity has never been my strength. At 66, my hands don't always
go where my brain tells 'em to go.
Trying to cut a compound angle in three dimensions isn't working for me.
I can't hold the bit still enough to grind a flat surface at any angle.
I need to build some simple guides/fixtures to constrain movement
relative to the grinding wheel. Of course, a better grinder would help...



All...all you "need" is a decent grinder where you can change the
angle of the "rest:" at the front of the wheel. There are tools out
there specifically made to do this

http://www.ebay.com/itm/Ralmikes-Too...-/171447956641

I have (2) of these in my shop. One with white wheels for HSS..and one
with green wheels for carbide. You will only need (1) with white
wheels for HSS

http://www.ebay.com/itm/1-2-HP-6-Too...-/321352325417

Mine are Baldor..and cost about $1000 each when new...shrug. But the
imports like the above will do the hobbyist just fine. And if you ask
Iggy..he might be able to find you a decent used one.

As for wheels...

or you can make a changeable fixture

There are countless videos on YouTube to teach you how to simply
sharpen a lathe bit, both HSS and carbide

Cutting/sharpening a lathe tool is easy peasy. Its not like trying to
sharpen an endmill or other complicated cutting tool.

Us old dogs need to stick together...

You need somebody to show you. But i know finding that guy ain't easy.

Barring that, you need something to make it easy. I'd suggest this:
https://www.grizzly.com/products/Hea...-Grinder/H7762

if you go this way, I'd go to using brazed carbide lathe bits and just
sharpen the cutting edge.


Remember Karl...on small light duty lathes...carbide isnt needed or
very usable.
