How to lace a 32 hole hub on a 36 hole rim?

Greetings fellas

Do you know of any example or have you tryed to lace a 32 hole hub on a 36 hole rim? I want to lace a wheel fixed/free, so I need a three cross lacing patern or two cross lace partern.
Welcome your suggestions.

This is not a good idea, because the rim will have unsupported arcs where the 4 missing spokes should have gone.

Using a hub with more holes than the rim is workable, but tricky.

First Thoughts: Why?

Second Thoughts: OK, if you really want to do this; you will have to "lose" 4 holes on the rim. So, that means 2 holes from each flange; you might get away with having empty holes diametrically opposite each other for the first flange, and the same thing but at 90º offset for the spokes from the other flange.

There might be a problem here, as on a good rim, the holes are usually drilled slightly offset from the centre of the rim so that they provide a better angle for the spoke to the flange; if you skip a hole, you now have the spoke going to the "wrong" flange (for that side).

Third Thoughts: see First Thoughts.

There are two possible ways I would do this:
1) Sell the hub and buy a 36 hole one
2) Sell the rim and buy a 32 hole one

Go ahead and try. The folly of it will sink in eventually but you'll have had good brain exercise while you're figuring it out.

The problem is what happens if his "folly" doesn't happen until he's out on the road and all the overtightened spokes rip through the rim?

If you use 24 spokes, you would use 12 of 16 on each flange, so 4 groups of three with a skipped hole, and on the rim 24 of 36 holes, so skip every third hole, each group of 2 would have a spoke from each flange. Probably go 2 cross with this. (have fun with the spoke lengths - probably need 2 lengths for each flange). Then I'd hang it on the wall and feel all warm inside knowing that I could do this - show it off to bike chicks and my riding buddies. Then buy/build a properly constructed wheel to ride.

This is the kind of thing you do if you are stuck in Desmaraisville, QC (pop. 3) with a broken rim and find a 1950 abandoned bike in the bush.

Why not carefully drill two additional spoke holes into each of the two spoke flanges of the hub.

No train wreck unless you want to use radial spoke patterns

Not impossible, but will likely be a grade 12 level geometry problem repeated 16 times to figure out the various different spoke lengths you will need, then a very long day of lacing and re-lacing until you get it 'right'

Much better idea to sell the rim or hub, and get one that matches the hub or rim.

am even more ridiculous idea than the 32 spoke in 36 rim

I am truly hoping this was satire, but not clear

Sheldon Brown at some point even recommended doubling the number of spoke holes in the hub, and then fumbling the different numbers of holes in the rim and hub together in a suitable way.



In case the rim does not have spoke holes alternately slanted sideways, this is the way to go:

Also, we'd have a good fail story with photos for the next guy who comes in here to ask the same question.

I did it once on a road bike front wheel. I road it for years and never had any problems.

I sincerely hope that, 15 years later, the OP has decided on how to proceed. I am curious if you have considered how to address spoke length calculation and lacing pattern with these carefully drilled holes.
