Backwinding and my Nizo 561m

[timothyx]

Hi All~

I've been experimenting with my new Nizo. What a fun camera!
I also purchased a Hama Backwinder and am looking forward to experimenting.

Here's my understanding of how it works. Tape off take up knob on the super 8 cart, shoot until jam (usually around 200 frames), take the cart out, take off tape, place in backwinder and wind until I feel tension again, put back in camera and shoot normally.

Q1: I'm assuming that (if I'm comfortable with loosing a few frames upon replacing the cart) I *don't* need a changing bag. That is, the backwinder fits snuggly enough with the cart that it's not being re-exposed to light?? Anyone have experience with this?

Q2: Am I doing any damage to my Nizo my taping down the cart so the camera can't take up the slack properly??

Thanks!

I've been holding off cuz I'm not sure, but it doesn't seem right that you'd have to tape off the cart take-up. Jamming the film will likely result in a torn perf, which you are then going to try and run through the camera again after backwinding.

Introducing tape into the works could gum things up. The take-up spindle on Nizos engages upon closing the cart chamber door, and though there is a clutch to accommodate rotational slippage, there is no similar mechanism to deal with obstruction to engagement - the spindle is going to puncture the tape, or get bent.

ISTMT you should run the camera as normal, then backwind until you feel tension.

Thanks Mitch!

Well, I have tried the backwinder when shooting as normal. Unfortunately when shooting normally (without taping) there isn't much, if any, slack left over to backwind. So when it seems like it has to be obstructing the take up somehow or it's not going to work.

From you words, I'm worrying that I may have already done some damage. I've already tried the technique with tape a couple times. Everything seems to be still working, so knock on wood. Screwing up my camera is the last thing I want to do.

Anybody have a clue how to obstruct take up on a Nizo or disengage the torque on a cart for backwinding??

Don't let my words worry you too much - I have zero first hand experience with the backwinder. I just assumed it would grab the take-up core, break the spline, and unwind/backwind until the feed side would not accept any more film.

Looks like we're going to have to sit tight until someone who actually knows chimes in...
