Hand Drill Update
More blisters.
I've found the source of my problems. I burned in this board with a larger drill and the current drill just isn't creating enough friction to generate the kind of dust I'd need for ignition to occur.
Last night I cut off about 1" from the end of my current drill and gave it another go. I had smoke in about 10 seconds but the drill end is still too narrow.
There is a trick involving a grain or two of sand under the drill to help create even more friction so I may give that a try today. Otherwise I'll have to use my current drill and burn in another hole more appropriately sized.
The thumb loops do make a big difference in the ability to keep downward pressure on the spindle.
Thanks for reading,
B
