The process of restoration so far, went as follows.
I am lucky enough to own a variac,so after checking
the motor voltage, which was 200 /250 volts,
I decided to power the projector up. There was a brand new
old
stock bulb in the wooden box in which the machine came and
I had
thought that it was linked into the motor circuit so I had
fitted
it in place.
This involves pressing down on the bulb and then gently
screwing
in the clamp screw
on the rear of the lamp housing.
All functioned when the power was ,raised but the motor was
rattling away like mad.I thought that I could detect a small
amount of side play in the motor shaft by pushing on the
small
pulley wheel. Well I thought I would have to check the motor
bearings,
but it looks like a lot of dismantling is needed to do that.
I then thought I would remove the motor cowl on the left side
of the projector.This was as easy as I had first thought.
There are five small screws holding the cowl in place.
Three are ok to remove, but the front two are not so easy.
The lower one can be reached by removing the front triangular
shaped cover plate and by easing the wiring to one side.
Top one is the hardest, but after easing the screw loose with
long nosed pliers, I found it could be removed with a finger
from each side of the pedestal.I would worry how to replace
them later !!
After removing the motor cowl and then the fan,I found that
there are two small screws each side of the motor shaft and
after adjusting these
with the motor running, it has quietened down considerably.
I am assuming that these screws affect the alignment of the
shaft, but unless I completely
dismantle the motor I can not say exactly what they do except
that all seems to run smoothly now.
I need to acquire an empty Pathescope reel and also the spool
drive cords. The main
drive at the moment is via a long elastic band, which worked
quite well
but I am sure it will be better with the round section
nitrile belt type.
I have now lubricated all the red.painted oiling holes and have
greased the gears that are
reached through the top and front covers.
Note: Most of the small screws (probably 6BA)removed ok, but
three needed a small tap with a small hammer to shock them
into life. A good dose of penetrating oil first helped I am sure.
The asbestos is in top order so I will leave well alone apart
from
a coat of sealer on the top edges, just in case.
All the black crackle is in remarkable condition, so no
repainting to be done which is a bonus.
Films in the box are Hocus Pocus (2 reels)
and some of the small Pathescope cassette type reels with odd
lengths
of film on them. Not sure how these can be used on the above
projector, although I do have an adaptor in the box which might
be for that type of reel.
