Reply To: Pivot drill tool…

Tom, Bob,
Another option for an extremely powerful small motor would be to buy a small portable air compressor from an auto parts store and remove the motor. I think the compressors sell for around $15.00.
Tom,
You can make a prototype of the machine out of gray PVC plastic. It saws and machines well and is extremely inexpensive. Once you feel you have mastered the process, switch to brass. In order to make the tool easier to make, design the pivot polisher around your available equipment and skill level instead of designing the tooling to make the pivot polisher.
