Tim's Clough42 ELS Install on a PM-1236T

[Just for fun]

I finished up the Clough42 ELS install on my PM-1236T the other night. It works great, it was a fun project that will make life a tad easier when I need to cut metric threads. And the fact that a person can change the feed rate on the fly is pretty cool also.

Anyway, here are a few photos of the install.

The two 18mm pulleys I got had 6mm keyway slots, I needed 5mm slots. So, I made a 5mm keyway broch and cut the correct size slot. I also milled the shoulder off of all of the pulleys and redrilled them for the set screws.





3D printed some prototype brackets to make sure things would fit. After I sure everything would work, I proceeded to slot the aluminum brackets. My aluminum welding sucks so no photos of that.






I 3D printed a mount for the control head to clamp to my DRO mounting arm.



Since my electronics cabinet didn't have a mounting plate for the back I mounted the mounting rails directly to the cabinet. At that point I needed some standoff pads, I printed some out of Flexable TPU.



I also printed a patch panel. And a cover for the electrical connectors on the Servo motor.

Nice! I made a keyway broaching tool based on Clough42's design with the clamping screw going horizontally above the cutting bit. Yours is much more solid. My bit has tilted in its bore about 15°. If I need it again I'll remake it like yours. One thing from his design that I will keep is a 3/32" hole (~2.4mm) that is parallel to the hole for the bit. A wire can be placed in that hole to assist with alignment. For a long time I wanted to add a treadmill motor and ELS to my Grizzly but ended up buying a lathe with a gear head and full quick change gearbox.

I made my first ever Machining YouTube. It is mainly done to show how I use @MrWhoopee threading retractor with my ELS system. It's not much and needs a lot of work. For some reason my camera wasn't auto focusing in video mode and I didn't realize it at the time. I went ahead and put the video together, it was a fun project. I thought I did just ok on the voice over I only missed my que once. Anyway, it was fun to make, I'll make another someday and see if I can refine my skill a little better.
