I have a question about how to get a nice and even wind when building up to a 6k house reel.

I just can't get it to wind smooth and flat. Is it a matter of not moving your hand at all or are my reels to wide apart?

Until stumbling upon this site I've always built reel to platter, so building up to house reels is relatively new to me. That being said, I am also suspicious of our House reels being faulty. Some are bent, others are missing inserts, and some are flat out labeled "Bad". What bugs me the most is how wide they look. The reels we have are the same ones pictured in the building 101 tips section. They're aluminum 6k reels. However, in the tips section his looks skinnier than ours.

What about the auto arm cutoff thing in instead of flange binding? My co-worker uses this method to get a even roll. The film has space on either side of it, though. Is this frowned upon?

Aren't you supposed bind to the side of the reel that lays face down on the mut, to avoid shifting of the film?

Are my reels too wide or do I just suck at flange binding?

MUT is a strong. Build up table/area is kelmar. fyi.

Fantastic website, btw.

I've never heard of a reel being just a little too wide. Does it look like the reel is perhaps twice as wide as the film? If so, then you have a 70mm reel.

The flanges on the old metal shipping reels could be opened and closed, as I recall.

Here's a section on Flange binding in this tips section for print builds.

When winding by hand, it's very difficult to keep the film completely flat on the side of the reel, especially if you stop (as you should) to check the print then start again.

So long as there's not a 'single' layer of film left to fend for itself in the wind (it will lose the battle) you should be OK.

Nah Ken, they are 35mm reels. I just felt that perhaps they allowed for too much play. They are about a 1/4 inch wider than the standard 2k reel.

Thanks John, I had a feeling I was worrying too much about having it completely flat. So a little ripple here and there is o.k., just not a lone soldier layer. Gotcha.

BTW: When winding on cores, there is a device called a tight winder that stacks each layer EXACTLY on top of the previous layer. This is how trailers are sent in with "perfect" winds. Louis

Time and practice... That's all it takes!

I've gotta admit, even with my vertical tightwind, I have trouble; the first few turns around the core seem to be offset from all the rest (I guess the core moves on the trailer flange?) and there is therefore a little "dishing" when I wind up trailers... Any tips?

I'm ashamed to say I rewind at home with Easton hand winders on to cores, with an 'adaptor' made of paper and tape. The winding is awful and to straighten it out I slam the film on a flat surface. I die a little inside each time though [Frown]

By the way, the rewinders have square keying with a spring loaded ball, what kind of reels did this take, goldberg 2000s don't fit.

Also, is there an adaptor for cores available, or a better idea than paper and tape?

Those are 16mm rewinders, so it is no wonder that a 35mm reel will not fit on them.

Damien those Easton winders you have are 16mm ones. The 35mm (which can of course handle 16mm reels) have a threaded rod and a large 'wing nut' lock mechanism. What you need is a split reel to work with cores or a plate. Have a look at work in your rewind room in cinema 1 and you will see what I mean.
