The new shed is not the only change that has taken place at "Craigmill"
!
The Raglan lathe has been replaced, a cutter grinder added to the tooling, a
MUCH better pillar drill purchased and the F1 mill fully converted to PC control.
The Raglan was still performing well but I wanted a quick change gearbox to
make feed rate adjustment easier. I searched around and monitored e-bay for
a gearbox or even another lathe without any luck. Then my luck changed, a friend
had purchased an EMCO Maximat 11 lathe through an advert in a local paper a
couple of years ago. While in his care it wasn't used very much and eventually
he decided to advertise it for sale. I made him an offer and the lathe was mine!
It is a joy to use and although accessories for these lathes are notoriously
expensive this one came with 3-jaw, 4-jaw independent and 4-jaw self centering
chucks as well as travelling and fixed steadies. The Raglan was moved to the
workshop at Kerr's Miniature
Railway and the EMCO installed in my workshop. This was not as easy as it
sounds as even with the milling head removed the EMCO is a seriously heavy piece
of kit. However both lathes were soon up and working.
The EMCO was originally purchased by a gentleman as his retirement present
to himself with nearly a full set of accessories, some of which are no longer
with the lathe and after his death the machine lay unused for a spell before
my friend purchased it. As a result of these periods of idleness the lathe needed
a lot of TLC to bring it back to proper operation, little things like the carriage
stop adjusting screw seemed to be rusted solid but it was just that the preservative
grease had hardened on the threads. The lathe has a two speed motor with reversing
facilities and spindle speeds are selected by a fully geared headstock drive
with the gears running in an oilbath. More details are available at Lathes.co.uk

The Maximat has a milling head attached to the rear of the lathe with a six-speed
geared drive. It has a 2MT spindle so all the tooling for the Raglan mill will
fit this machine. I haven't used it for milling yet but it runs smoothly and
has the advantage that the head can be tilted allowing for angled drilling.

When I started to build "Sweet Pea" I used a Clarke Hobby Bench Drill
from Machine Mart. This drill might be fine for drilling wood etc. but is definitely
not accurate enough for model engineering. I couldn't understand why the loco
valve gear jammed solid when all the fixings were tightened up. The reason was
that the Clarke drill table was not at right angles to the column and the piston
rod tapped holes were squint in both crossheads and other drilled holes were
less that perfect. A local second hand machine dealer supplied the "Startrite"
drill that I now use and I'm confident that any squint holes will be my fault
and not the machine's. The Raglan Mill is still performing well though the X-axis
feedscrew may need attention soon as there is a bit of free play developing.

This Alexander Grinder was a lucky purchase from e-bay. Normally these machines
go for in excess of £250 but I got this one for £150 because the
seller described it as a router sharpener instead of a cutter grinder so there
were only two other bidders rather than the dozen or so who normally chase these
grinders. It works well and I've sharpened engraving cutters for a friend but
have yet to master the sharpening of milling cutters. I suspect I might have
to make a jig to correctly sharpen these items.
This last view is taken from the door of the workshop looking towards the F1
mill now fully converted with the ungainly EMCO metalwork removed and sitting
next to the PC ( which has been upgraded since the photo was taken ) with the
industrial LCD to the left of the mill, the box above the screen is the box
housing the Xylotex driver boards and power supply.
