4th Axis with TailStock

This is a 4th axis and tailstock project that I build for my CNC. The base and tailstock block I printed with PLA carbon fibre 3mm solid walls, top and bottom it is a over kill but.

I removed support material with screw driver it take some time but it works.

If you are not able to find M12 1mm pitch you can buy M12 standard bolt no threaded all the way cut it with grinder and tape it with M12 1mm pitch from any tool shop because the chuck thread is M12 1mm don't ask me why it is Chinese.
