The Holmes 8 has no troubles with notched sprocket holes.I've notched film since the late 70's and have only seen a few that had problems in the projector. I'm working on an old IB feature that has nicked spocket holes every foot or so all through all of the even-numbered reels. Most of the repairs have been done using splicing tape, but some have had to be notched carefully. It takes time, but when I'm finished, it will run just fine. Now, if this print was received for a run in a theatre, I'd demand a replacement print, pronto! I know that you guys dont have the luxury of time when you inspect prints. I am sorry for this. "Integrity Inspected?" Yeah, right.

Some platters will rip a V-notched print to shreds if you aren't careful. Try to avoid any extreme twists or edge dragging. Perf durability is the #1 best all time good thing about Estar film, IMO... -Aaron

"V" notching was the recommended cure for checked out sprocket perfs during the old carbon arc days in the US Navy. That was taught in the MPO school. If memory serves me correctly, the maximum of V notching was two adjacent sprocket holes. Any more than that, it was recommended the frame be cut out. Since the advent of the polyester prints, I never saw a "checked out sprocket hole." Paul

Understood, Gordon.Is it my imagination, or is IB film more prone to having brittle base stock? I've got several IB features that have alot of minor damage here and there along the perf edges, and occasionally there are runs of perf breaks along the center of the holes. I get the breaks aligned properly, and lay on the splicing tape. I dont see this much with my acetate Eastman, Fuji, Agfa, etc. stuff. Think it's just the old age of the IB print showing? My youngest IB print is from 1971, and the oldest is from 1960. Is the old age idea right? FilmGuard has done a nice job on these prints. Before FG, I would discover new perf edge breaks sometimes when rewinding a just-run print. Now, nothing. All the guides and rollers on the Holmeses are free and correctly adjusted. This damage was random, like possibly old damage that finally gave up and broke. I assume that the FG is either super-lubricating the print so it slides through the machine, or it's actually soaking into the base and improving its flexability. I just ordered bottle #4...
