I am Pretty Sure It would Take Me Less Than 1 Day

Post by S8 Booster »

to make a perfect pressure plate for the Kodak Cart to allow as stable film transport as with any R8/DS8 or Single 8 cam - if I had the time.

considering there are loadable Kodak carts available.
Metal plate - adjustable - to be adjusted to each individual cam cam gate via adjustable spring loaded guides. initial adjustment has to be made with plate in gate only.

next, the spring system behind the original plastic pressure plate is trash. to be replaced with multiple coil springs of various force.

i believe some of the problem behind the bouncing/curling of the film is due to the silly location of the pull down claw and the film interacting with the plastic pressure plate with wrong friction/inertia. the film resists moving, curls and moves back after the claw releases.

some asymmetric spring pressure and lubing should do the trick.

no, i am never going to make it.
no i will probably never live long enough to get so old that i get spare time enough to do it.

how to verify?

precision perorate a pin hole film at the image center while installing a small LED behind the pressure plate so the cam projects the pinhole light to measure the stability - or a precision super imposed crosshair. but not so good.

it could work for me but probably not for you.

difference, i may try....:)

This has been discussed already in http://www.cinematography.com/index.php?showtopic=59680

In a super8 cartridge, the "pressure plate" is just a fixed backstop.
