Clark Resident Perfects Device

Greenwood Man Is Well Drill Expert

Greenwood---An accessory which will save many hours of working time for well drillers has been developed and perfected by Leo A. Bredesen of this community.

The appliance is a bit sharpener, which may be attached to the driller derrick and which will do in 20 to 30 minutes what normally takes three hours. Bredesen explains that without such a sharpener it is necessary to take well drilling bits to a shop for sharpening.

The Greenwood man, who has been engaged in well drilling for the past 38 years, also uses a "hammer sizer" device of his own invention which maintains the correct bit size during the sharpening process.

He says his invention is the only gravity type bit sharpener on the market except for one which sells at four or five times what it will cost to manufacture his sharpener and plave it on the market.

He has patents pending on his contrivance and is now seeking a manufacturer. The invention Bredesen says, is the product of about 10 years of thought and three years of work, and he has been using his model with success since last spring.

Because well drilling in this area usually entails drilling through many feet of granite, Bredesen uses bits which he invented for such use. They have three cutting edges at each end, and as a result they bore a straight hole into the granite.
