Cletus' PM-935TS-3PH Mill Log

[Cletus]

Rechecked the tram again today, now that I've used it a bit. Reassuring to note the X, Y and the vise are all within 0.0005"

I love the simplicity of the angled aluminum as a tilting mechanism tor ergonomics there, getting the micrometer to an angle better for viewing on a flat surface.

Hahaha, it did not start off simple. I had a pretty convoluted AutoCAD drawing of how I wanted to make it, with a whole bunch of machined parts. But once I played with the big endmill on that piece of scrap 2" angle aluminum, the drawing went in the trash and I just kept going at it freehand. I'm quite pleased with the outcome, it fits my needs perfectly, very comfortable to work with and I think there is some elegance in the simplicity

Making tools for the tool with the tool!
Quick speed handle. Shaft and socket press fitted and pinned-through with M4 grub-screws.
Got to play with my boring head, reamer set, V-Blocks, hydraulic press and knurl tool.
.......My Shop-Vac's eating healthy these days!

I'm refurbishing an Operating Room Light. Setting up the CNC Rotary Table to index some cuts and some holes. The machine is beginning to earn it's keep!

….Here are some preliminary pics (note the blue HDPE glides I made, worked like a charm!)…

I recognize the look on the face of your daughter, it appears to be universal…

It’s the “I know I’m supposed to be supportive but this is asking too much” look. I got that look the other day when I told my wife I wanted to get a mill to keep the lathe company.

Very cool indexer, when are you going to start selling them.

 

[Cletus]

If you are interested in making one, I can send you the Arduino code

Oh Yeah!

For those interested, here's my adaptation of the Arduino code for the stand-alone CNC Rotary Table (unclear who the original author is, so I cannot extend proper credit) :

For those interested, here's my adaptation of the Arduino code for the stand-alone CNC Rotary Table (unclear who the original author is, so I cannot extend proper credit) …

Thanks, that’s interesting. My programming skills are very rusty, but I could work out what was going on!

It looks like it would be a fun project!
