Here is one of my machines which I have change a few parts on. I did this before I purchased the Boss. It turns slower than the slowest speed on the boss. Some day I will adapt another head with the gears reversed to speed the bit up for peg holes, or construct a whole new machine for such a purpose.



Here is a home made version, something along this line for peg holes.
Excuse the shaky camera. You can hear one of our wind mills wisping in the back ground. I hesitate to decommission an older machine for readaptive use.
