I never really had this problem, but then again, I usually don't build up anything with two-perfs that's going to be over 3000' feet or so for that very reason. Too much tension WILL tear that splice to shreds. Generally, I do four perfs worth on each side. That does the trick, and you're not wasting tape.
On another related topic, the best cement splices, for what it's worth (not much anymore with polyester) are made by Maier-Hancock or the Bell and Howell Pedal splicers.

Thanks, everyone, for all the info.
Another question I had was answered in a couple of the replies.
(It DOES require pre-perforated splicing tape)
Fortunately, I found and bought several "expired" rolls dirt cheap in a professional camera store here in San Francisco.
The stuff is still apparantly good, as I tried using it to splice together a couple of test loops and let them run through one of my projectors at home for over 30min each and they appear just as strong as when I made them.
I worked in film production back for awhile in the 1980's and I can 2nd the comments made by some here that an experienced editor could make splices lightning fast on one of these things.
As I recall, I saw these mainly used on dailies and for editing work prints, and they taped only one side. At the place I was at those edited work prints were rarely projected. They were usually only run on flat-bed type movieolas, which don't put a wholelotta stress on the film & splices.

Is there a special "8-perf" version of this splicer? Is it possible to make an 8 perf splice with the standard 35mm model?
Thanks!

BTW, I hate that system notices thing. It dupes me into thinking someone's responded to my queries! Then, I click on the thread & "Bang!" that lame message.

When working on preservation at WB, I had the use of a beautifully equipped booth (outside of Studio jurisdiction), and had one of these along with an ultrasonic splicer inherited from MGM, thru Turner.
I always had an awful time lining up the perfs with the film, and getting an unwrinkled splice.
As mentioned in an earlier posting, however, watching a professional editor with lots of experience use it was fascinating. Bing-bang, done!

I got a deal on movieola type splicer on ebay. We'll see. I think it looks tough to get a good splice on one of these. Lining up the perfs looks like a pain in the butt.

The key to getting a clean splice was to hold the tape just above the film and let the razor assembly apply the tape to the film. Squeezing the tape gently along the sides allows you to hold the tape parallel to the film, without it "drooping."
The 2-perf version was called the "inviso" splicer, but it used a stronger, stickier tape.
I've never heard of negative cutters using tape but I guess anything's possible. Picture editors *would* only splice on the base side. Once the decisions had been more or less nailed down, someone would have to apply the tape to the base side for trouble-free projection.

Incidentally, does anyone know who has the most inexpensive pre-perf? 3M used to make REALLY good tape, but apparently they either don't make it anymore or changed the formula, because the quality of the adhesive on the tape I've purchased recently is very poor.

Try Christy's Editorial -- they're in Southern California -- I know -- they're on the other side of the country -- but I have no experience with New York (other than being a tourist there) -- best I can do.

Numbers film supply in Toronto Canada has the 3m tape. I've bought from them & like their service.
