Big OOPS.

Oops.jpg We are just south, west and east of the 5 tornadoes that hit the Cleveland area. Allegedly this was just straight line wind. Tree cleanup will cost a arm, and a new car the other...

Most likely they can be found at less expensive stores, but they work well for verniers and other "must see" situations.

Gentlepeople: I have an old (?) Producto mill that is small and somewhat useful. My dad added the grey drive motor that advances the x axis instead of the odd drive shaft that was original.

Re: Using Forstner bit To Drill 19mm Hole in Aluminium
