My uncle has recently rescued an elderly Drummond Type B lathe (pictured above) from being thrown in a skip.
I believe this dates from around WW I.
A few bits and pieces are missing, but it's mostly complete. The one big problem
is a couple of gears have split, so I will be making up some replacement items to help
get the old girl "back on the road".

22-Jan-2006: There's the two gears made of cast iron and
both have snapped like carrots. It looks like an attempt has been
made to build up new teeth with a welder, the subsequent heat destroying
the gears. Also pictured is a 14DP 14.5PA cutter from Tracy Tools. |
|
11-Feb-2006: Some tooling has been made up to hold the gear
blanks. This will eventually go in the
versatile dividing head to allow
the blanks to be machined into gears. |
|
18-Feb-2006: The first of the gears has been produced, another
one to go and the job's done... |
|
12-Mar-2006: This is the setup used for cutting the gears.
The versatile dividing head is mounted
on a vertical slide. |
|
Another shot of the slide + VDH. Cutting 14DP gears using this precarious
setup takes time... |
|
Two passes were made round the gear, trying to cut the full depth in one hit on
this setup is maybe too greedy. |
|
Job done! |
