hello everyone tonight

This is an old problem solved a long time ago

Boring holes endwise through logs to produce pump logs for use in dug wells

The logs were stationary, and long augers run then by steam power on moving frameworks slowly moved forward and back to clean out the shavings, they could drill through up to 12 foot long logs

They used pod augers especially adapted to bore into the end grain, and held the shavings as the pods were withdrew.

These pods had spiralled ends rather than a thread, and worked really well going into the end grain

The pods were about 12 inches long and open on the side, of really hard steel about 2 inches in diameter

the pods came on sets and could increase the bore sizes to 4" for the top logs that held the sucker for lifting the water using a simple setup

I hope this information may give you guys some background information on drilling holes endwise in logs, maybe you can adapt something similar using a modern drill attached to long tool steel shank

A temporary setup in a shop could hold and guide the long drill, I am sure you could come up with something that would suffice
