Parts Identification and Description (Continued)
Drive belt
There is a bolt fitted through a hole bored and threaded in the front edge of
tensioner
the motor plate. Driving this bolt 'down' will cause it to 'push' against the
(See fig8a)
main frame and force the motor plate to turn on its axle, forcing the gearbox
and motor axle further apart and therefore tightening the belt. Once the belt is
tensioned the bolt is held in position with a lock nut.
Transition
This is the gearbox that transposes the motor drive though 90 degrees to the
gearbox
saw wheel and gears the speed down to a usable rate.
(See fig 8)
Wheels
The wheels are 185mm diameter, tyred and rim edged. The driver wheel is
(See fig 7)
fixed in plane as it is mounted directly on the transition gearbox shaft. The
front wheel is mounted on a tilting axle yoke that allows the wheel to be
tilted so that the blade can be tracked.
Blade tensioner
This is a threaded rod with a 'star handle' moulded at one end. The rod is fed
(See fig 7)
through a bushing in the end of the main frame as far as the handle, with a
'skid' washer to aid turning. The threaded end is engaged in a threaded dog
mounted on the front wheel yoke. Tightening (screwing in) the rod will pull the
yoke and therefore the front wheel towards the end of the main frame thus
tightening the blade.
Blade guides
The guides fulfil two roles, the first of which is to twist the blade the final
(See figs 8)
complement angle to achieve vertical to the base, and the second is to hold
(See figs 9,a,b,c)
the blade in position during cutting. There are three guides in each set. The
two side guides which perform the 'twist' and keep the blade in line, and the
thrust guide, which maintains the up/down position of the blade between the
side guides. The thrust guide has a groove ground into it to help prevent the
blade 'skidding' away from its cutting line. The guides are mounted in slot
housings machined in the main frame and are adjustable along the exposed
section of the blade. There are safety covers attached to the guide
assemblies that maintain cover over the blade when the guides are moved
The position of the rear guide set is normally locked using a cap head bolt,
against the position of the vice, the front guide set is locked with a 'star
handled' bolt against the clearance required for the material being cut.
Blade and
This is the main cover for the saw frame. A pressed steel plate held onto the
wheel cover
face of the frame with 5 No. M4 caphead bolts and shake proof washers.
(See fig 5)
On/Off switches The On/Off switch enclosure is mounted on the swivel quadrant so that it
(See fig 8b)
maintains position with the saw. There is a striker on the main frame of the
saw (See fig 9e) that depresses the Off button when the saw has reached the
lower limit of its cut and therefore gives an Auto Off function. The striker is
adjustable (a threaded bolt and a lock nut) so that the switch off point can be
accurately set. The switches are marked as standard with 'I' indicating 'On'
and 'O' indicating Off. The switch has a NVR function so that the saw will not
inadvertently remain On if there is a power disruption.
Vice
A good capacity KWIK action vice mounted directly to the base. The clamping
(See fig 5)
jaw is free to move on a long rod, that is clamped and 'squeezed' forward by
the action of the clamping lever handle on the side of the vice. The vice is
bored to accept a length of rod, which acts as a mounting bar for the preset
length stop. (See fig 9d) The preset length stop can be positioned along the
bar and locked in position using an M6 Bristol Handle.
