We’ve been looking for a boring machine for a year or more. Last fall, we saw two at the local flea market on the same day, but for some reason we decided to pass on both at the time. I can’t remember why.
This year, in May during our timber frame workshop weekend, we had a chance to use Tom Cundiff’s Millers Falls machine. Wow! It was a workout, but made boring holes for mortises much more practical with human power. Since then, we’ve been looking pretty steadily.
