40 hole hub - how to lace ?

Wondered if any of you know if you can lace a 40 hole hub into a 36 or 32 rim.

You can do it but its going to be a bit of a pain. You have to do a little math to work out the spoke lengths following the general principles set out here:

Lacing to a 36h rim is probably best as you'll only have to skip two holes on each flange, but figuring out a strong lacing pattern is probably going to take a little trial and error.

How did this go?

Have 40hole SA hub and cannot for the life of me find 40hole 27" rims in alloy.

citygent,
it might be worth getting in touch with Hilary Stone in the classifieds, he was selling some undrilled rims, not sure of the size though.

Bikey, you are a legend! I have no idea how the hell I will drill them, but I guess Hilary/BQ will know.

From a wheel quality thread, on here.
I ended broosing a german bike site.
I spotted some rims that I want, but not in 24h.
They did have 'ungebohrt' though.
Did some googling around.
Drilling rims sounds bloody tricky, was the resulting conclusion.

small world.

Actually, thinking about it. the tolerances on a 40h rim would be far smaller. As it would be easier to correct imperfections with your spoke key.

Maybe.

The undrilled ones sound like quite a job. If you don't go for that, I've been considering unlacing a wheel that has a silver wolber 40h 27", not perfect but in fairly decent nick.

Let me know if you want first refusal, I was going to sell either as parts or complete on a thread at some point shortly, along with a stripped Jalco 32h front rim and the pair of airlites.

Also, I passed on another Wolber 40h 27" to someone on the forum (that was laced to a 40h front hub), trying to remember who it was now, I feel certain it's sitting in their cupboard still ... I seem to recall it was Tiswas ... could be worth asking him...

Skully: if those rims are in alloy, I would love them. It's a build for my girlfriend and she won't ride steel rims even during the summer. I'll give TisWas a PM now.

yep, wolber is alloy, as is jalco.

Yeah ask Tiswas forst, if he hasn't got it any longer come back to me.

May not have to, there's a geezer on ctc offering to swap the hub shells over.

You might not need to look for 40h one as I may have a 36h SA 3 speed hubs in great nick going for spare soon.
