I have been using designing, and building tools for about 60 years. It is the favorite aspect of my hobby. I am located in Boulder CO right at the eastern foot of the Rocky Mountains. I have accumulated a fair collection of machine tools over time and paid my way through graduate school in Mechanical Engineering with them!

Hi Bill - welcome to HomemadeTools.net

Sounds like you'll fit in well here

What's next up on your projects list? Can we help out with any ideas?

Thanks for the kind thoughts! A project that has intrigued me is something called the Balshazar Backing Off device. Invented back in the 1890's it form relives things like involute gear cutters. Rather than my trying to describe it's operation just google it! There is a video of a version that has a hob and drag leadscrew backing off a gear hob! Amazing to watch! Producing a form relieved involute hob is pretty high end machining! Bill in Boulder CO USA
