POST #1 - MILLING MACHINE
Here are some pictures of parts for a 1/12 scale model of a milling machinie. There are over 50 pieces to made
many of which are threading, taper turning, crowned pulleys, etc. Will CNC as much as possible utiliziing Lazcam, the Wizards,
etc to produce the gcode for as many parts as possible. Of course some manual coding also.You just can't beat CNC when duplication comes into play. The little three ball handles can be a pain in the neck even when all the cutters are already made but not so with CNC. So until the model is done you just get to look at some of the parts.
Other model work which is complete can be seen in POST#2 to 4 in this thread.

Un-freaking-real. Wow. You've got more patience than most of us, for sure. I see that some of the parts are cast. Whats the story behind that?
-
I'm with Sam, WOW :o :o :o Those are great Rich.

Thanks Sam,
There are a few outfits that sell kits. You get some castings for some parts and enough material to do them along with a
a set of drawings. In some cases, like the pulleys, I don't use the castings as it is easier to just use some bar stock. The kits are fun do do but it takes time and you need to be in the mood. The mill has a lot of turned parts thus one of the reasons for wanting the threading and turning capability out of MACH. I use the three ball handle as an example because manualy doing them and holding a thou takes about 4 hours from start to finished piece, sometimes longer. With a CNC lathe turn one in about 4 minutes! Of course I had to learn turn which is paying off. If you get a chance, go to a model engineering show. Some of the things those guys do are absolutely amazing.

One supplier of kits for model machine tools is PM Research, http://www.pmresearchinc.com/store/home.php?cat=6
They offer many machines, and also several model steam engines. Many of them are aluminum castings, they also offer a couple steam engines in brass. They also have an extensive line of model parts, like pipe fittings, pressure gauges, etc. Nice people to do business, with, always exhibit at the major model engineering shows.

WOW - that is some engineering you have done there.

Now, where are you going to find the little tiny operators for all your equipment? :P

Didn't you ever hear of Leprechaun's? ;) I get the small ones at 4 for a $ at the local flea market. Trouble is they keep disappearing when it's time to do work. Will never get the mill done! ;)

The more I look at these the more I love them. Fantastic work and as my wife would say, "how friggin cute are those!?!?"
-
Was that the machines she was talking about Dave ?
-
funny guy! :D
-
Rich,
Freakin Fantastic. You gonna set them all up on a line shaft?
Only 1 motor needed. I remember them days.

Ed,
No line shaft, although they do work. I just have them in small display cases.
Currently sitting on top of the sterio speakers in the family room. They look so much nicer than the
ugly vases from my mother in-law.
;D RICH

Rich.
LOL, Yes, motherinlaws tend to do that. Give you all the ugly crap. ;D
Look what I got.
You can't find any 1/12 scale cnc stuff either ? :D
Good job.

Hi All,
Time to start making some more parts for the model again. The pictures show one of the universal joints completed for the model. I could of just softened a bearing and drilled two holes thru it, but, instead I decided to CNC turn the ball.
Attached is the gcode for machining the ball and a picture of the pointed tool used. The code does a complete finishing pass after the roughs. You need a tool which will not gouge the ball as it goes around it. You don't need to change tools when done this way and and the part has a nice finish.

NEATO MAN !
Nice work RICH..THANKS for the update.

Nice job Rich,
But , I want to see it cnc ed. :D
For outside radiuis , I usually use a outsie radius mill cutter clamped in the tool post . gives you an accurate radi without having to grind a tool bit.
But if you don't have , then you sharpen a tool bit.
Thanks for the update.

Hey Ed,
All joking aside. One of the projects i thought of doing was to make a small miniture CNC machine.
I have some small steppers laying around and good grief enough junk to do it.
I have some outside cutters and in fact ball tools already ground that would cut the ball, but it's more fun
or challenging to CNC it.
