A die attachment for easy / accurate bullet seating adjustments. Also has info on gauges worth making.

See attached file.

Not much machining to do for this project. I wanted a small, light weight, solid and easily adjustable pistol
rest I could take to the range which could be used for any pistol size. This rest allows one to just sit at the bench
in normal position and not be bent over when sighting the gun.The rest  will work for a small pistol like the Ruger
LCD to the large frame S&W 29 with 8” barrel.

Item #1 is a 1 ½” diameter base and allows for  2"  of fine adjustment and has a locking collar.  The small base
rest does not interfer with  one or two handed gripping of the pistol.  
  
Item #2 allows for 4" of front and 3" of rear height adjustment. The front pad has a large round filed into the
soft rubber pad.

Item #3  the bottom base, has four leveling screws and the grip bass is slotted / can be rotated 180 deg to provide
for a wide range of horizontal movement ( 2- 9”+).

Tested the rest out at the the range and works like a charm. :)

The attached is just quick write up on making a set of custom pistol grips.
CNC was used to probe the gun frame and create a dxf from acquired points.
Internal machining of the grips were then done.

Just having fun,

Finally made a universal gun sight tool. Still need to do a few tweaks and make some things for it.
It's robust and calculations done to confirm what was done. Not too much CNC was required.

Attached file sheds light on the influence of machine configurations and feedrate on probing.

G-Code, CAD, and CAM discussions / FUSION 360 - LATHE
« on: February 07, 2017, 08:49:04 AM »
Thought I would start a thread on using Fusion to model and generate Gcode for the lathe.

I just started "playing with it" and a friend was kind enough to provide instruction on how to sketch and model in it.
Like all new software one tries you just need to go through the learning curve. Generated code based on a .cps ( post processor )
provided for Mach3 lathe which can be downloaded from Fusion site.

Frankly, rather impressed with it and it can do a lot.

I'll post more on my learning over time.

It's that time of the year again.  The Expo is this weekend at:

LEBANON VALLEY EXPO CENTER
80 ROCHERTY ROAD
LEBANON, PA 17042


SHOW: January 14th & 15th, 2017
Saturday: 9:00 AM - 5:00 PM       
Sunday: 9:00 AM - 3:00 PM

Always nice to see  familiar faces.

Artsoft have any plans for seminar's?

Enjoy,

RICH

Would like to change the XMode in lathe from or to Radius or Diameter via button script without going into configuration> Turn Options.

Is it possible?

HOw do I get a Mach 3 program for plasma cutting only tilldirt@itstriangle.com
( Posted by Vernella June 24, 2016 )

Which Mach 3 program do I buy that will run my plasma cutter tilldirt@itstriangle.com
( Posted by Vernella June 28, 2016 )

Hi My plasma quit moving and I am trying to buy a new program to fix this tilldirt@itstriangle..com
( Posted by Vernella July 03, 2016 )

This the third time I have ask does standard Mach 3 run a plasma cutting table I have not been able to
find the answer Dick tillldirt@itstriangle.com

TOOL SHARPENER
Not much CNC work as this was a build as you go kind of project.

I have a Darex end mill sharpener and it works great and also use A Foley saw sharpenener as a bench grinder, but,
never used the Foley much because the grinding dust went everywhere.
Shop space is rather limited.

As the used / chipped / broken carbide end mills and lathe tools start to pile up wanted something to prep them for finish grinding.

So started looking at all that "stuff" one collects over time to see what could be used to  make some general use carbide grinding fixtures.

Some thoughts on the matter included:
1. Cheap / "this is not going to cost much" ( hobbiest creed!)
2. Use the "stuff" you have
3. Must be easy to setup, rather accurate to minimise use of expensive diamond
   wheels for rough sharpening.
4. Be able to sharpen carbide lathe tools including inserts and end preparation  
   of broken / chipped / end mills.
5. Keep it small, is movable, and can be easily stored away.
 
So the attached file shows some of the things made.

Note: When you make a fixture the mounting needs to be accurately done as that provides for easy and accurate setup. Keep things symetrical about drilling, based plates
square etc.

SAFETY NOTE:
Pay attention to recomended and max rpm of wheels. Don't believe the cheap stuffs claim that it's good to 30K RPM. Test anything you make for runout and vibration. I put a rated 35K small wheel in a bench mounted die grinder and it went into vibration at about 15K bending the tool steel arbor ...almost jumped off the bench ( it was rigidly clamped down). Be carefull!
