Hello Rob,
I don't think the leader can be repaired, as the used polymer doesn't
react well with glues, simply out will not be robust enough.
But if you have some patience and a sharp knife, topi can cut out new
leaders from black plastic layers, I used old X ray films of the bones.
I did it for all of my drives (only had broken at start), and it worked.
For me it was tricky to find the right shape of the original leader, but
you have the damaged one...

I tried fashioning my own leaders from various materials but could never
find one robust and flexible enough compared to the originals, so did in
the end resort to buying a stock.

Has anyone tried film or audio tape splicing kits?

Yes, I tried 35mm film but it isn't robust enough.
I need to look in to what I have. I don't use TK50's anymore.
The other potential option is to use the leader of a more modern drive as a
'donor'.
Mark.

It needs to be stiff and well attached to the actual magnetic tape.. I don't think
Gorilla Tape is. I think something like the clear film in a shirt stiffener might
work....
There is a TK50 piccy well down this page here:-

I think that is the same as the TK70

Other possibilities that come to mind are "Gorilla tape" or
"Taear-Aid"
repair tape. I haven't tried either on magnetic media, but they're
pretty tough.

Looks like he tore out the end hook on that
tape as well, there is a gap
in the photo of the disassembled cartridge, but there is clearly a loop
in the photo above as he holds the door open.
I'd think the tolerances on the shape and strength of that would be
pretty tight, so fabbing one up may be tricky. Harvesting one and
splicing with some luck may be a better way to go if possible.

Makes me glad that we never bothered with the things on our 11/750.
1/2" 9 track was the exchange medium of choice.
