Inletting, Jo-blocks, Irregular Turning – heard of any of these?
By Tony Gunn
This is a great story of engineering ingenuity. Cast your mind back to 1846, not that easy perhaps, but in this fantastic story, Tony Gunn from MTDCNC meets a number of the team from the American Precision Museum.
The facility started in 1846 and there are still original pieces of equipment that Dave Eastman, Steve Dalessio, Molly Holleran and more talk us through.

- What would you use to turn irregular parts?
- What is a Jo-block?
