Hi David,
Well, I've fished out the bag(s) of yellow sleeving - one continuous 5-metre length and a bag of "umpteen" (100) by 25mm sleeves, the set of 'bodkin' sleeving tools, a Larkspur aerial pigtail and the bottle of "Hellerine" lube.
The "MJ8" bodkin takes the pigtail (which I assume is P11 cable) and I can slide a 25mm sleeve over it well enough - 50mm might be harder work to get it off the bodkin - probably needs a polish as there's a bit of surface spotting, and more Hellerine might help. I'm not sure the prongs on the pliers are long enough for much more than 25mm, and they're not immediately to hand anyway. (Also, the tool itself may not be strong enough to expand a 2-inch length of the sleeve unless it was softened by heating first.)
Printing on the sleeve is going to need some suitable ink (craft shop or a company that prints on rubber) and probably metal type - though I've seen one-off cables with handwritten labels and a protective layer of varnish (probably applied later).
Wording will probably be "CONN. SINGLE No. C7" or similar followed by the stores code. I've got "Leads, Aerial No.9" somewhere, spelled in full!
I'll see what I can dig up, it might be an interesting project.
Best regards,
Chris.
