My homemade drilling and tapping arm

[Black Forest]

This is a quick video of the drilling and tapping arm I built for my shop. It is hydraulic. I can drill with it or tap. It has a reach over all of my welding table except for where the post is.

I don't know exactly how big of a tap it will drive as I only have up to 20 mm taps but it taps as if in butter at 20mm in steel.
