Hi all,
I'm wanting to replace the spokes on my front wheel, and the chart in the Parts Book, and Draganfly's Parts Book aren't that helpful. I have a 19" rim, with 7" half width hub. Now, from what I can find, 67-5544 and 67-5545 are for the 8" half hubs. I'm assuming the 7'' half hubs have different spokes? If anyone has the correct part numbers, I'd be eternally grateful.
Regards, Tony

My experience of professional wheel builders is that they build the wheel and trim off the excess spoke length thr'o the nipple with an angle grinder, then cover with the rim tape!
Swarfy.

Part numbers won't be of much use these days, and length doesn't cover everything. There's also length between bend and head to consider, as well as the angle of the bend (for non-straight spokes). You'd be better off taking out one of each and sending to a spoke supplier as pattern. Remember to send a nipple too, as they come in different diameters.

Some spoke info.
Alsoavailable on the mikeb site.

On the topic of rim tape, what are people using generally these days??
-
Purpose-made rubber rim tapes. A couple of turns of some sort of sticky tape is just vile.
-
I find today's rim tapes to look / feel cheap. Usually rather thin, of material that doesn't look as if will last and of absolute minimum width. And so I use 3/4" self-amalgamating tape.
-
"self amalgamating tape" RDFella, I've never heard that expression before, can you give me an example I can google?? thanks
-
Unlike insulating tape, it is not sticky, but adheres or 'fuses' with itself. Slightly stretchy and of greater thickness than modern plastic insulating tape
-
I use it for extra traction on Guzzi twist grips because I'm limp wristed. And yep, with one of those clip on paddle devices also.

Self amalgamating tape...
There was a period when BT used 'Tape, Self Amalgamating' * to seal cable joints. I used it a few times. It's good stuff.
That was the style of the GPO/BT rate book description. So, 'Pliers, Terminating, No2' would be snipe-nosed pliers.

'Tape, Self Amalgamating'
Yep, good stuff with many uses must get some more, not cheap but usually when you need it solves a problem

Used on HV cable joints too. Nice and gooey for that purpose but I can't see the advantage in having that in the wheel rim, but each to their own and all that.

And similarly "AT1" (also snipe-nosed pliers) always written as "81's" by dopey storemen.

Hi All
I would not use self amalgamating tape as a rim tape, It will bond to the inner tube
At least any variation of it I have come across will bond to rubber

I was trying to remember that. Yes, 81's! *smile*
There was a theory that the abbreviation AT1, was short for Apparatus Terrminating No1. Everyone called them 81's
-
Thanks for the replies, I've had a look and tend to agree with John that it might bond to the tube and I've found some decent rim tapes made by Dunlop or Michelin in 19" for $5, sounds good to me *smile*, cheers
