This is the column of the mill, it is an 65 x 50 bar with a dovetail
slide machined on the front onto which the milling head is
mounted, the lower part there is a pre-drilled hole which slides over
the tilt housing shaft and secured in place by a 36mm nut. On the left
side of the post a scale, graduated in mm's, is mounted to read against
a pointer mounted on the head casting.
Rise and fall, there is a dovetail slide machined on each side of the the
headbox support column which mounts a through shaft. A pinion gear
is mounted on the shaft inside the headbox that meshes with a rack on
the support column, driving the pinion shaft will cause the headbox to
rise and fall up and down the headbox support column. The part of the
shaft protruding from the headbox has a hole through it to mount the
tri-lever feed assembly.
The tilt housing is mounted to the base casting using 3 M8x30 caphead
bolts and washers. The tool post is mated to the housing and clamped
by a 36mm nut. The main tool post can tilt 45˚ from the vertical either
left or right. There is a pointer and a scale mounted on the housing to
give an indication of the amount of tilt that has been applied.
This is the 'milling machine' and the descriptions of its
various parts and components are detailed as follows:-
The main casting to which all the components are attached. The
head has a dovetail housing machined at the rear, which allows
the casting to be fitted to the Main Tool Post. The left side of the
dovetail slide is fitted with a gybe strip to maintain the fit.
Located to the right side of the main tool post above the gybe strip
adjusters and locknuts is a handled bolt that clamps the gybe strip
against the slide to effect a locking action for the rise and fall of the
head.
The motor and gearbox assembly are mounted above the main
head casting at the top of the arbor sleeve. The motor drive is
geared through to the spindle with an intermediate 2:1 gearbox.
The gear change lever allows the selection of the high or low ratio
of the gear train. The speed of the spindle is then governed by the
speed control on the motor panel. (You may have to 'joggle' the
chuck/tool to aid the meshing action).
A 220V d.c. motor rated at 350W.
