Yet another 620 repsooling question...!

jay moussy · Sep 27, 2020

I have yet to respool, and came to realize there are at least two techniques:

- hand-unwind 120 and gather film in hand, then spool end of that on 620
or
- winding onto an intermediate 120 spool to reverse film direction, then spool on 620

I am not sure which one would minimize finger prints and the like?

Wind (forward) to a 620 spool, then wind back to the intended 620 supply spool.

Why a 620 for the intermediate? Because this lets the film accommodate to the smaller spool core on the forward transfer, when any slack that builds up won't come up against the tape when you get to the end of the film. Done this way, there's a good likelihood you'll be able to make the second transfer without even needing to untape and retape the head end.

"But I don't have a spare 620 spool!" Of course you do -- you have to have one for the supply and one for the takeup, right? Don't be afraid to borrow the empty one out of the camera.

Thanks, makes a lot of sense!
Yesterday, I was toying with a very old, thick Kodak backing onto a 620, and I was wondering about the paper's willingness to comply!

You'll have more trouble with film that's been curled for even a single decade, never mind half a century. The change in core diameter might be enough to cause the film to try to loosen. Be sure to tape down the leader after respooling, and seal down the tail after exposing and unloading.

+1
But if you don't have a second 620 spool, contact me, I have a couple extras laying around somewhere.

+1... if it helps.

keep it tight at all times!

Get a Foldex 20. Perfect tool for respooling onto 620.

jay moussy · Sep 27, 2020

Thanks, I do have two 620s because, er... hmm, I bought stuff with spools in them!

Old film: As a beginner (a few months ago), I decided to practice getting film on Paterson spools, using ancient 135 and 120 rolls, and the bloody things would NOT go on!
Eventually I found a fresher film to practice, went on first try, full on, just by magic!

@thuggins what makes the Foldex an ideal machine? Among my herd of 620s, there may be similar candidate for the task?

MattKing · Sep 27, 2020

I use a Mamiya C330 to wind on to an intermediate 120 spool.
The straight film path seems to just work for this.
I expect that a Foldex is one of the cameras that can hold an unmodified 120 spool in the feed side.

Eh? Wot?

When film is wound from a 120 feed spool to a 120 or 620 takeup spool it is ends up with the end of the film that's taped to the leader on the inside of the roll. It then has to be wound back to a 620 spool so that the taped end of the film is on the outside of the roll so that the film will feed properly through the camera.

I believe you're correct. Puts your film onto a 620 intermediate spool, and some folks report being able to use the Foldex for the rewind step as well -- I've never figure out how they get the loose end of the film to pass through onto the destination spool, but that's the claim.

Dan,
I think you missed the reference to an "intermediate" 120 spool.
The OP's original post offered two options, with the second one being:
"- winding onto an intermediate 120 spool to reverse film direction, then spool on 620"

Matt, I was responding to your post, which I quoted, and not to the original post.

Yes, but you missed "intermediate".

Matt, I quoted your post #9 above. The word "intermediate" doesn't seem to be in it. I just checked.

Good heavens, you're right. Selective vision on my part.

The Foldex fits both 120 and 620 spools.
