I get several calls each year with problem descriptions something like this:
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.
I can't seem to change Speeds (or Feeds) 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.
"Lest We Forget"
For machine Serial Numbers from 41B2910 thru 41B3009 and Serial Numbers 42B3606 thru 42B3708
These machines originally have Mobil DTE24 oil or its equivalent in the Speed Gear Box and the Feed Distributing Bracket.
The oil in the Speed Gear Box should be changed to Mobil DTE Light or its equivalent. The Feed Distributing Bracket oil should be changed to Mobil Heavy-Medium or its equivalent.
Spindle Sleeve Installation and Head Service Notes
Spindle Sleeve Installation Tip 1:
The installation of the Spindle Sleeve into the headstock of this range of serial numbers is complicated by the use of (2) 'light-duty' Timken tapered roller bearings to provide support to the rear end of the spindle sleeve.

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.
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.
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.
There is much confusion regarding the use of cork & rubber gaskets and liquid gasketing compounds (IE Permatex) on Lucas boring mills.Here are the 'rules'.
If the 'cover' you are going to gasket has NO mechanism that is part of it - go head and apply gasketing material as you see fit.
