Parts Identification and Description

Please read through the section entitled Identification and Description of Parts, so that

you will be familiar with the terminology we will use in the manual, so that you can

identify the parts quickly and easily.

Mounting

A quadrant casting, bolted thro' to the base at the front apex, the quadrant

guadrant

swivels about the bolt and is secured in position by a clamp bolt situated to

(See fig 5)

the rear of the quadrant which is engaged in a curved slot in the base.

Towards the rear of the casting are two trunnion castings, through which the

pivot axle of the saw is fitted.

Scale and

There is a scale decal set around the rear curved edge of the mounting

preset stop

quadrant, and a small adjustable arrow pointer fastened to the base as an

(See figs 6a & 6c) index mark, these will allow the swivel angle to be read. There is an

adjustable preset stop on the base which strikes against the right hand edge

of the mounting quadrant, this together with the scale and pointer can be

used to set the saw to cut at 90˚ to the plane of the vice.

Mounting

Mounted on one end of the pivot axle this casting mounts one side of the

pivot yoke

main frame to the quadrant. There are three holes bored through the web of

(See figs 5 & 6b)

this casting that will locate one end of the feed tension spring in different

positions, and therefore alter the reactive torsion in the spring, giving different

feed rates.

Main frame

This is the casting that mounts all the other components of the saw proper. It

(See fig 5)

is mounted at an incline on the quadrant, held on one side by a bearing

housing that fits to the pivot axle and on the other side by the mounting pivot

yoke. There is a rectangular box housing cast on the upper side of the frame

that mounts the components of the transition gearbox. There are also two

small trunnion castings at the rear of the upper side that mount the pivoting

axle for the motor mounting plate. There are various other housings machined

for mounting the wheel axle yokes, the blade guides, et al. There is also a

handle shape cast at the front of the frame to give a gripping point when

raising and lowering the saw.

Feed rate

This is a shaped torsion spring mounted concentrically on the pivot axle of

spring

the saw. One end rests against the quadrant base and the other is fed

(See fig 6a)

through one of the holes in the mounting pivot yoke web. The spring acts as

a counterbalance to the weight of the saw. The three holes give an adjustment

of the amount of torsion applied to the spring, therefore governing the 'feed

rate'.

Pulley and drive A pressed steel casing comprising an upper and lower section. The two

belt cover

sections are hinged together. The lower section is secured to the main frame

(See figs 10)

about the axles of the motor and the transition gearbox. The upper section is

the guard enclosure for the pulley towers and the drive belt. The two sections

are held closed by the hinge and a bolt.

Motor

Single phase motor rated at 550W. It is mounted on a plate which is in turn

(See fig 8)

mounted on an axle which allows it to pivot and act as a tensioning device for

the drive belt.
