Re Nimslo Surgery

[P3D Peter Homer <P.J.Homer@xxxxxxxxxxxxxxxxx>]

The Nimslo Surgery that Grant Campos wrote about was also tried by Ralph
Hughes of the UK Third Dimension Society, he wrote about it in their
bulletin 105 in 1988. But he found that there was then " a small amount of
light could be seen at the film track, coming past the drive sprocket." So
he fitted a " sliding panel with an extension to engage the shutter-setting
lever. Originaly he tried Geoff Thurstans modification from TDS 101 and
102. This consists of removing the base of the camera and disconecting the
shutter cockinng bar by removing the circlip . Then cutting a slot in the
base for the bar to pass through when the base is replaced , you can cock
the shutter by pulling on the bar but it is no longer possible to cock by
winding on as well . He was concerned by the fragile bar being exposed so
he went on to develop his own method .
  I did try Geoff Thurstans less drastic method myself but later on decided
to reconnect the bar and widen the slot in order to hook the setting lever
with a wire as Grant Campos describes. But even in this lower position on
the camera I did eventualy get problems with light reaching the film so I
fitted an "L" shaped slider around the bottom and front of the camera with
a screw through it to engage the shutter setting lever.
 The other lever that Grant Campos discovered which efectively gives a T
setting to the Nimslo is described on sheet 12 of the Nimslo service
department technical information. Which is published in the second book
"Reel 3D Enterprises Guide to The Nimslo Camera ". Its original function
does seem to have been for service engineers to check lens collimation
after removing the front cover. I think it might be possible to use for T
settings if it can be made to operate from a cable release with a second
one in the shutter button to close. Also it does seem possible to operate
the shutter cocking lever from this position so perhaps one slider to good
do bothe jobs , sliding one way to cock the shutter then back the opposite
way to open it.     P.J.Homer
