My comical CNC lathe story and does anyone have experience with gang toolposts?

[Rob]

Hi, thx for both replies. I made a video to send to the guy who made the toolpost (youtube link below). His English is limited so I did repeat myself a few times and also I really had no proper idea what I was talking about :) Since then I started to take it apart and found I was completely wrong in that the two set bolts are in fact the ones that are used to adjust the gear position and which I have adjusted numerous times now. It works for a while then slips.

The motor voltage drop would explain how they solved the tool from bouncing up and down, I was wondering about that if the belt would hold it with tension from the motor. The motor is also getting very hot though which worries me.

Anyway, the video still shows the changer quite well so please have a look and let me know what you guys think. I'm pretty sure he did make it himself and well done to him, but I just don't know what to do to about this slipping. Plus the motor is getting very hot.

PS: I haven't got to the point of using the Orac with g-code yet, only using the manual jogging. I'm hoping to ask a friend who used to work with cnc lathes to explain the basic Mach3 turning wizards to me when possible as the cad/cam process is a bit daunting right now. I can't even understand (yet) how the different types of homing works. I'll get there eventually.

As much as an auto tool changer is a nice idea, I still like the idea of a gang tooling arrangment. Also, this man, (maybe the forum knows him) made a really nice tool post https://www.youtube.com/watch?v=IfYLgENFvIk
