I shifted gears and went with a Milwaukee M28 right angle drill with a winch bit. Might be a tad heavier, but it's more powerful and batteries are not an issue. Several club mates liked my version and acquired including the friend who had the Winchrite.. Might be time to bite the bullet,, All in the Milwaukee was $495.
