The early blocks were cut at 90 degrees and 45 degrees, but the later Editall types were cut at 87 degrees for quarter-inch tape (and as shallow as 83 degrees for wider tape formats), plus the 45 slot. The link I posted earlier explains why (to reduce 'bias transition noise' over the edit).
The EMItape blocks which were in widespread use bolted to the Beeb's tape machines always had three slots. I believe the 'vertical slot was at 89 (rather than 87), but it certainly wasn't 90. The other two were at 45 and 60 degrees. The 89/87 degree slot was only used for declicking vinyl disc transfers and sometimes for cutting in leader tape. Anything on a half-track stereo tape (at 15 ips) was always edited with the 60 degree slot, while the 45 slot was only used for full-track mono, which had mostly been obsoleted by the time I was being trained. The 60 slot could also be used for 7.5ips mono (Uher) tapes, but stereo at 7.5ips really needed the 89/87 slot to avoid 'flash edits' where the image rushes across from left-to right as one channel is edited slightly before the other. (For really critical work, we would cut 'fish tails' by hand with brass scissors so that both channels are cut at the same time, but still with a short cross fade!)
If you can't find an Editall block, it would be fairly easy to cut new slots at any preferred angle into the Splicit aluminium block if necessary using a hacksaw with a decent blade.
I will be using it to edit both stereo 2-track tapes recorded on a Revox A77 and 8-track 1/4” tapes recorded with a Tascam 388.
I'd suggest a 60 degree cut for the stereo tapes, and the 90/87 slot for the 8-track tapes. A 45 slot on the stereo tapes is likely to result in flash edits.
I’ve seen some on eBay that are over $125!
Yes, I've seem some going for £95 recently. I'd certainly try and get an Editall or EMItape type if you can as they are undoubtedly the best to use.[/quote]
