Anyone have any reccomendations for other old iron sites? I have a
Hendey-Norton Universal Miller Early 1900's vintage. Quite an amazing
machine for it's age. Horizontal mill with vertical mill attachment.
Variable speeds to powerfeed X&Y axis two speed manual z travel with a
swiveling table. I'd like to find more about it. Most of the patent
dates are from the late 1888-1899 years. Up until I moved it out of
the shop this was a working machine.

Mike,

There is an antique machinery section on the PRACTICAL MASCHINIST'S
BOARD:



Someone there may be able to help you with your miller.

On your Dalton, there may be a formula at the bottom of the thread
chart to calculate the feed rate with the clutch. On the B-6, the
formula is: "FEED = .288" / THREAD"

That means: with the gears set to cut 72 threads per inch, the feed
rate with the clutch would be .004 / rev. ( .288/72 = .004)

The formula on the Lot 5 / B-4 may be different.
