"having to make sure that you do not get metal particles where they shouldn't be, the blades would have to be removed in such away as not to distort the shutter disc"
If anyone tries to cut the blades with the drive shaft still in place they will need to make certain all the internal works are covered obviously. The 926GL has never been a popular machine with experienced cine users because of the reel design and this is the very reason they so often sell for very low prices. You can also see a two blade 926 running perfectly in a clip on youtube so yes a two blade shutter can be done on this machine.
As mentioned in my review I would not attempt this modification or any other repair for that matter if you are not competent.
Happy days!
