Jeff Joslin Vintage Machinery entry for Fred W. Wappat
|
Description: |
This invention gives improvements on the cutting of bevel gears. Co-inventor Wappat went on to become one of the first makers of handheld circular saws, but before that he manufactured gears. So far as we know the Wappat Gear Works did not manufacture their gear-cutting machines for sale. |
