My PTE won't eject a tool for the first several hours of each day (or after a weekend shutdown); however, it suddenly begins working OK, and then its fine for the rest of the day.

or

The History of the Lucas Machine Company

Manufacturers of the World Famous
Lucas Horizontal Boring, Milling and Drilling Machine

 

On January 1, 1900 at the age of 30, Henry M. Lucas organized the Lucas Machine Tool Company with George C. Lucas and Frank Yost as his partners and they soon began production of the world famous Lucas Boring Mill at the original factory on East 99th Street in Cleveland, Ohio. Their first machine (Model #1) was shipped in 1901 and ran to a production of 351 machines.

Typical Machine Foundations & Hardware

Most Lucas boring mills build after 1950 were designed to be installed on a foundation to provide mechanical support for the machine.As impressive as the main bed castings are on a typical Lucas, they are NOT a 'self-supporting' structural element.If a machine is supported only at the four corners, it is astonishing how much the castings will visibly bend from their own weight.

Used Machine Extraction Check-off List

This reminder list should be used when moving a Lucas Machine from one site to another.It is particularly valuable in assisting a new owner to secure all of the 'parts' of a machine he has just purchased. The list may not be totally complete for any given machine (since so many models and variations of Lucas Machines exist), and is primarily intended to provide a 'starting point'.

NOTE: If the original owner has (or had) more than one Lucas Machine, check for the correct serial number on ALL of the items listed.
