Hi guys,
My mate was having a clean out on the weekend and he kindly donated to me a Velocity B43. "thank you" I said. I then realised it had 48 holes.
Of course I can get a 48 hole hub no probs but was wondering if it would be possible to lace to a 32 hole hub in the interest of weight savings? I know that a) why would i want to do something stupid like that for? (b) a hub with the same number of spokes as the rim is the best option (c) mismatched combinations are for advanced wheel builders (which i am not) and (d) 16 spokes weigh stuff all in the scheme of things...
There's plenty of forum discussions regarding mismatched combinations just not this particular combination.
Can any one suggest how this could be done?
Of course it would mean 16 holes in the rim would not be laced and if it were to be done according to my logic every 3rd hole would be missed which would mean that 2/3 of the holes in the rim would receive a spoke. How am i going here???
Im just not sure what cross pattern could be used. 2 x would work mathematically as would radially with gaps in between - but what about other combo's. Im going to do a few sketches tonight to see what I come up with.
Would appreciate some suggestions. Thanks -

No. You'd end up with a fucked up, broken wheel if you so much as sneezed near it.

"Yes, this is horrible, this idea." -

Really?
Ok...I just figured it could work considering you still have a relatively high spoke count.
Whats the deal then with these rims with grouped drillings rather than drillings evenly around the rim? -

In the interest of weight savings, I'd put that heavy polo bike B43 aside and get the proper 32 hole aluminum box rim that is a lot lighter. It would make a lot easier on you when it comes to lacing also. -

yeah I realise that its not that practical to build this up for a light weight commuter. However, if i do ever take up polo...
Given that I got the rim for nothing I just thought I would consider any other options available to me. -

Yeah, 48h are great for polo, tandems, freestyle/flatland bmx, and any other heavy duty applications. Get yourself a 48h hub and build up that beast. I'm building up a pair of 48h box rims for my bmx. -

lace it to a 24h american classic hub. -

I have a very interesting SunTour 48 hole with a freewheel that has a feature to turn it into a fixed cog. Odd, went back and forth with the owner of Yellow Jersey. Specualation is its for a pacing tandem at the track, or for new tandem partners to have the option of freewheeling if they get out of sync when first riding together. Stamped Maeda (Suntour's parent company) 4835. No other naming or identifying marks. -

24 hole on front and rear wheel would be sufficient. That's one of the road wheelsets I use.
If you want the rear wheel a little stiffer for hard accelerations, then use a 48 hole hub, but use 36 spokes. The drive side will use all 24 spokes, 3 cross lacing. Here's where things get interesting, and I've posted this technique on another wheel building thread. Use 12 spokes on the non-drive side, laced 3x. This will form 12 groups of 3 spokes. Ever 4th hole on the rim will go unused. The tension on all spoke will be nearly equal instead of the non drive side spokes having half the tension of the drive side spokes. DON'T radial spoke anything. -

This is totally a sweet idea, but its wheelbuilding 401 not 101. I would do 24 spokes either 4 or 5 cross on the drive side, and 1 cross on the non drive, but that is personal preference not necessarily theory.Posted By: socal3renshoI have a very interesting SunTour 48 hole with a freewheel that has a feature to turn it into a fixed cog.

That is either an OG freecoaster hub, or the freewheel designed to go on one of those original freecoaster hubs just randomly on a different hub. SkidMark made one of those freewheels at home, I believe. Here is some info about what it sounds like you have:

I'll probably go with the 48h hub with 48 spokes but i do like the sound of lacing all drive side and half of the non drive side.
So I assume this technique would mean that on the non drive side of the hub: one spoke head facing out, then empty hole, then one spoke head facing in, then empty hole...and so on and so on?
Cheers
