Here is the knife sharpener I just finished. Works fantastic. I realy wanted something that is rigid,
could do just about any knife or whatever, totaly adjustable, had good feel when stoning, was easy
 to use and set, can be set and reset accurately,and had a good  hold down system. Also didn't want to spend much money. Only cost was the $15 for the digital caliper ( modified to a sliding scale) and two diamond stones.

Pic 1S is the sharpener. Everthing is machined perpendicular or parrallel as required for accurate adjustment.

Pic 2S shows the rotating bearing, sliding / rotating rod , stroke stops, and digital setting scale.

Pic 3S shows the adjustable holder for different length stones or laps and one of the holdowns that are used.

Pic 4S shows a 40x magnification of the beveled edge put on my Pro S Heinkle 10" carving knife. Yes, you can shave with it!

This was just one of those projects that I enjoyed doing since it was a usable household item.
Nothing beats a simple tool that does it's job extremely well.

Members Docs / GCODE PROGRAMMING REFERENCE
« on: May 14, 2013, 07:43:00 AM »
The Mach manuals  provide specific information about the gcodes it uses.
They can be found under Support>Documentation.

An excellent comprehensive guide to programming is CNC Programming Handbook by Peter Smid.
Another book by Smid is Programming Techniques, but, woud recommend the above one.

The attached workbook has a lot of information on programming for the mill which should be helpfull if wanting to learn programming.

Tangent Corner / SANDY - ONE WITH AN ATTITUDE
« on: October 30, 2012, 09:10:44 PM »
Sandy visited Delaware and went on her way to say hello to other states. Hopefully we not see the likes of her again.
She really showed an attitude not becoming of the typical stormy personality.
I must admit that local to my place we were very lucky and only lost power for 10 hours.
A lot of folks elsewhere were not so lucky though.
Hopefully your experience was only a matter of inconvenience also.

Attached is a rough draft for how to cut  NPT threads using the Simple Threading (lathe) wizard. You won't find much,if any, concise info
on using it for this task. I was asked to do some tappered threads and it's been a "few years" since doing one.

It was desirable to do the threading in a precise way. The result is the rough writeup attached.
Any comments appreciated. Will probably put the final version in Members Doc's or the Threading on the Lathe Manual as an appendix.

BTW, if interested and want night time reading on tappered threads, have a read of ANSI-B1.20.1, 3, 5.  ;)  ::)

General Mach Discussion / MACH3 MANUAL UPDATES
« on: January 21, 2012, 10:15:02 PM »
I just updated "Threading On the Lathe - Mach3 Turn" write-up which is located in Members Docs.

The link in Support>Documentation / Mach3 takes you to Rev 0 of the document and it is now at Rev 2.
Can someone fix that link?

Thanks,
RICH

This is the latest version of the software.

V2.86 fixes a bug where the material number was using the same DRO as the Xcenter value in the circular hole array wizard.

General Mach Discussion / MISSING STEPS HCIR
« on: February 27, 2011, 04:57:48 PM »
Having a problem with missing steps. Figured I would post and seek suggestions.
The complete program code has numerous use of the example problematic code. It is repeated in a simillar
fashion throughout the program.The attached code is just an example  which  may cause skipping ( X axis only).
 I can only run the code reliably at 10 IPM. The mill is very reliable to 80 IPM.  Matters not if run in Cv or exact stop mode.
The code provides small combination X &Z moves. I don't mind running the code at a slow  feedrate for finishing but need to up the IPM
to save hours on the pieces to be done.

 So any thoughts on the above ie; increase kernel speed .............?

The attached pics show the pathing , GREEN LINES, which will be used for testing by doing loops.
