Title: A junkyard lathe and mill tool grinder
Post by: vtsteam on September 12, 2013, 06:42:01 PM
(Note: I recently needed to cut left hand acme threads to complete the boring table for my Craftsman 12" lathe. I found an internal threading tool making thread here on Madmodder, but this led to also wanting to make a tap. The inside tool was produced on the lathe, but the outside tool seemed better made on a grinder. What follows was originally part of the boring table thread, but I've split it off into its own topic here.)

I was hunting around online for a simple sharpening jig for regular lathe tools used for outside thread cutting and came across a really excellent one by Martin Cleeve here:

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

Very simple, and so very appealing, to me at least.

Here's my start on it. I found a piece of scrap bracket 3/8" thick and sawed off a piece:

And was able to use my homemade carbide mill to clean it up:

And I used it to clean up all three pieces -- mostly bits of scrap. By this evening, the jig was almost finished. Just a few more tapped holes and couple pins are needed for it to be ready for use.

It get's worse, Jeff:

I remembered I had a  bench sander that I picked up a while ago at a tag sale. Thinking that this might be something I could use with the new jig to grind tools I dug it out.

I knew the belt sander part's table casting was broken. And I already have another belt sander that I use, but I had bought this one for spare parts or another project. A dedicated sharpener seems like a good cause. Here's the broken piece:

I decided I just needed the disk sander part, so I cleaned the motor up, and plugged the sander in -- it worked. I held a little fine sandpaper against the disk to clean it up:

I had an 80 grit sanding disk -- the adhesive was a little old so I sprayed the back with a little 3M 77, let it dry  some and then stuck it on the aluminum disk. I found the guard, but none of the fasteners for it. Luckily they were SAE sizes and I happened to have 1/2" 10-24's for base screws, and even a couple of 1/4" carriage bolts to fit the square holes for table support pivot bolts. Mine were too long as seen in the photo, but a couple minutes with a hack saw and a file and they were shortened to size:

Post by: vtsteam on September 14, 2013, 09:47:21 PM
Then I mounted the disk sander table, and put a 1/4" lathe bit blank in my new sharpening jig. It turned out that the original socket head cap screws I  had were too short for this size lathe tool, and I didn't have any longer screws of that type on hand, so I used some round head screws temporarily.

I tried out the new tool grinding jig for position. Pretty clear it wasn't going to work as-is. The rectangular mounting plate that the tool holder sits on interfered with the guard and the disk itself. You can just see it against the guard in the photo. Also the whole jig needed to be moved back further.

I'll make a different table tomorrow to fix the problem.

Why make a new table make the jig fit the groove .

Jeff
Title: Re: A lathe tool grinding fixture
Post by: PekkaNF on September 15, 2013, 04:48:36 AM
Can the motor rotate in both directions? Would that circumvent making a new table? If the problem is limited movement on x-axis.

Post by: PeterE on September 15, 2013, 05:56:09 AM
Like Jeff said above, make a new slide that follows the groove. The slide can easily be nearly twice as long as the tabel which will allow for passing over the edges and still be quite stable. Done that you can also add a tool holder that can rotate around a center which will give possibilities for an angular scale of the same type as the Worden tables - see link http://www.hemingwaykits.com/acatalog/Worden_Mk3_Tool___Cutter_Grinder.html (http://www.hemingwaykits.com/acatalog/Worden_Mk3_Tool___Cutter_Grinder.html).

Thanks guys!  :beer:

I thought about  using the existing table and using a slide, but as Pekka said the problem wasn't just interference , but also the table isn't wide enough to get the tool tip at the periphery of the wheel. The motor isn't reversible I don't think -- at least by me. A slide extension is possible off the table, but I think the action of the wheel will tend to kick it down on the left side, without support.

I could extend the current table, and I think that would work. I might still do that if I don't like my early morning wake up solution, which is to just remove the table and substitute a piece of angle iron bolted to the left side of the guard where the current pivot bolt is located. Very simple. Maybe too simple.... :scratch:

I do think this will allow me to lower the height -- another problem of the Cleve jig I chose to make. The tool tip ends up pretty high. Okay on a larger wheel -- but this one is only 5" -- 125mm. I could abandon the jig if I don't like it -- nothing sacred about it, and the idea of a slide and retaining the old table does still appeal. It's a good one. Well lets just see how the angle iron works out. Not much to it.

Thanks very much for the feedback!  Nice to know a few people are following, and I appreciate all suggestions. :wave:

The motor isn't reversible I don't think -- at least by me.

Most likely the motor is single phase permanent capacitor run model. Simple addition of single pole changeover switch after power switch should do the trick. Same connection than on "Quorn" TCG book or simple lathe:
http://www.anaheimautomation.com/images/ac/wiring/ACW040%20Wiring%20%28600x344%29.png

But if you don't want to fiddle with electricity, I understand it also pretty well.

Thanks Pekka! I'll open up the connection box and check. It would be handy to reverse. No, not afraid to wire it differently.

Thanks again!  :beer:

Post by: vtsteam on September 16, 2013, 05:49:25 PM
I made the side table today out of angle itron, and tried it out. It had a few problems -- it was only 2" wide, and the jig really needed a wider table. I clamped another piece to it to widen it, but on top it was too high, and underneath it was too low. I was able to try grinding a tool, but thought I could do better than this setup.

I decided to try to work with the existing table and the slot -- as suggested earlier by chipenter and others. I think this sander originally had a tiny sliding miter gauge, but that wasn't what I really wanted.

After thinking about it for awhile I found two small pieces of steel -- I needed something thin so the fixture wouldn't end up too high. These were 1/8" thick:

I have a spot welder that I got a couple years ago from Harbor Freight. I don't get to use it very often, but this seemed like an ideal job for it. After cleaning off the two pieces of metal, I welded them together, and milled the narrow strip to fit the slot in the sander's table. It was a little oversize to start with .5" while the slot was .460".

I spot welded two more strips of 1/8" x 1/2" to the top side of the slide. These will serve as slide guides for the tool holder, also seen in this photo. I've removed one of the original pieces from  the holder, as it's no longer needed.

Title: Re: A lathe tool grinding fixture
Post by: S. Heslop on September 16, 2013, 06:52:41 PM
Hey this is good. I was just thinking about how i'd grind an acme threading tool a couple days ago.
Title: Re: A lathe tool grinding fixture
Post by: vtsteam on September 16, 2013, 09:22:36 PM
It seems to work well Steve.

The X slide lets me use the whole disk, unlike the original Cleve jig. The Y slide allows me to apply pressure by hand which is a lot more sensitive than a mini leadscrew adjustment (I did consider a fancier version) and has the great advantage that you can pick the small tool holder right up off of the table and dip the tool end in water to cool it while grinding.

The rake of a cut is set by the original pivoting table, and the angle of the tool grind is set in the tool holder and its base/slide.

A paper sanding disk relieves worry about using the side of my regular bench grinder's disk, and I don't have to take shelter from it every time I start it, as normally recommended for a grinder. It will get used frequently as a result.

I'll get some better photographs of the sharpener tomorrow, and the resulting lathe tool -- it was nearly dark when i shot the last two pix.

Of course the slide could have all been milled from the solid -- a 3/8"  (10mm) thick piece of stock would have worked the same. And this could be adapted to just about any disk sander.

Here's a test piece of scrap turned with the acme lathe tool sharpened with the new fixture. the threads are pretty good. The tool is a bit too wide at the tip -- so the threads are just a bit narrow at the tip and correspondingly wide at the root, but otherwise I was impressed with the first effort. Just a leetle beet more off the sides of the tool and the tip would be right.

It's difficult to measure the tool tip width without an acme gauge while grinding -- I'll probably end up making something to do a check with.

But very pleased with the first results.  :dremel:

Today I thought I'd try a new experiment with this tag sale sander. First step was to blue up one of the slide pieces, and mark a line 1-1/2 degrees off square. I decided to do this using a little math since that's a pretty small angle to mark with a protractor.

The piece measured 2.10" long, and I wanted to know how far out to make a mark at one end to yield a 1-1/2 degree angle. I figured the tangent function would do it. With the pocket calculator TAN of 1.5 degrees x 2.1 = .055. So I needed to make a mark .055" in from one end, and then connect it to the other end. This is what it looked like:

Post by: vtsteam on September 17, 2013, 04:45:31 PM
Then I started filing to the line. I could have milled it, but I don't have a rotary table, and by the time I set up the mill and got that heavy vise over to 1-1/2 degrees, set the cutter height and did edge finding, etc.....well it was a lot quicker and easier to just file it  to the line. I might have spent 5 minutes total -- and it was nice doing it outside in the sun on this unusually cool day.

I bought a barrel of aluminum scrap at an auction once, and there were a lot of one inch square bar cutoffs -- maybe from a screw machine room.  I took one of the aluminum blocks and another strip of 1/8" by 1/2" steel, and positioned them to space the new strip an inch away from the one I just filed, and parallel with it. I clamped the steel strip down with a welder's clamp.

Then I took three of the aluminum cutoffs and faced, drilled, and reamed 3/8", 1/2" and 3/4" to fit some end mills.

Checking out positioning, it turns out that for shorter mills the slide can be on the close side of the sander's table slot:

Title: Re: A lathe tool grinding fixture
Post by: vtsteam on September 17, 2013, 05:22:33 PM
And for longer mills, I can turn the slide around so it is on the other side of the sander's table slot. The 1-1/2 degree relief angle stays in the same orientation, either way. The blocks can be rotated 90 degrees and replaced in their slide to sharpen each of 2 or 4 flutes.

Tomorrow I will work on a stop, a slide clamp and the adjustment method, and I hope, sharpen an end mill. I have a big box of used mills that someone gave me, so that would be kind of nice!

Well spotted Boriss. Yes the table tilts, and will be set to the proper angle(s) when it comes time to sharpen a test mill. I just left it at the angle I had used for the lathe tool when I took the photos. There's more to do before I try it out. Thanks for responding!  :beer:

     Amazing with all the new technology now, we know stuff all over the globe within an hour of it happening. Unlike when we were lads when the "news" would take days to make it down under.

I must say right on time. I have a nice belt/disc sander and the disc just sits there spinning because I use my pedestal grinder to do my tool grinding. But using the disc I can cut more precise settings much easier. Thanks for the update and show up on my radar. I'll be using your ideas to make it work for me.

I actually never finished the end mill sharpening part of this project. Almost there, but lacked stops. I'm going to pick this back up as I have a big bunch of dull end mills in need of sharpening, and they are getting rather expensive to buy!

(Heh, it took me about 20 minutes of searching to find this old thread -- I couldn't remember what the title was, and searching on "belt sander" and "Delta" didn't work. Couldn't remember where I'd left things either. I do have all of the mechanical stuff, so on with the show...

Post by: vtsteam on May 10, 2022, 08:31:16 PM
Thanks RSMP.  :beer:

I wanted to get a feel for how it worked before making the stop, just to see how well it functioned and in case I wanted to change anything.

Also I've been suffering with a bad 1/2" I need for a long slot in another project I'm working on. That mill was so bad that it screeched bloody murder when trying to take an initial .010" cut, and had the whole mill table jumping when trying to plunge at the start. The flutes didn't look that bad, but I think one of the corners was burred, couldn't quite tell with just glasses on and no magnifier.

So I decided that would be my first experimental victim, using no stop, just sharpening by feel and eye. Well that's not quite true since the angles are all set by the fixture, and really all I needed to do was decide how far to plunge the mill into the sanding disk. I decided to just touch it lightly, and repeated that for both sides. I could see that the grind was even. I think it took me at most a minute to plunk the mill into the holder, tighten the setscrew and grind both flutes.

It looked good, but would it cut? Did I have the angles right? Were the flutes even ectually?

Well, I don't know about the technical quality of that sharpening job, but I do know that mill plunged quietly to .040" into a slab of chewey hot rolled steel, and sliced out a 4-3/4" slot with no complaints whatsoever. It was an end mill transformed!  :ddb:

Hard to believe a junked and broken cheap sander could put a properly formed cutting edge on an end mill. I don't know what to call this thing, maybe the Antiquorn? Not to take anything away from the Quorn, and this is certainly less versatile, doesn't do the side flutes, and is by far less beautiful. BUT, it just provided me with a near lifetime supply of usable end mills (old ones given to me mostly).

I'm feeling stupid for letting this project lapse for 9 years without even once trying it out, while I bought end mills, some of which lasted minutes through an error by user. And for trying to get by with dull ones, taking .010" cuts, and suffering cramps from long hours trying to cut through reasonably thin materials. Milling projects that might otherwise taken a quarter or less of the time.

Well anyway, here we have the first slot being cut with a sharpened mill from the Antiquorn:

And a touch up by hand on the Antiquorn, and it looks like so....

Will it cut? I dunno. It isn't tomorrow yet.....

Is it hydrogen embrittled because it was electrolyzed? I dunno, I haven't broken it yet.....

Try Firefox, or Seamonkey (same thing with mail bundled in). Then use StartPage for searches, remove Google, and you're free of 95% of the user directing. Add the NoScript add-on to block all scripts you don't want to run and be happy once again that you control your computer.

Anyway back to the OT. Yes that formerly trashed mill works beautifully. Maybe junk mills like junk mill sharpeners.....

Really good achievement. it is one thing to build a tool grinder and altogether another thing to sharpen endmills succesfully.
Good Work!
