Is it possible to lace a 36 hole rim to a 32 spoke hub? The rim i have on my bike now is a piece but i dont mind the hub and the hub from my old wheel is broken so i want to put the rim (36) onto the the new hub.

its obviously possible but youll just have to have some of the holes in the rim unfilled and try to do it evenly and ill be nice and do it for you...lace 8 holes then leave one all the way around and it should be even.

Just buy a new rim, they are inexpensive enough.

it is possible but it is a compromise. plus you may not find anyone with the right skills willing to do it, so you may have to do it yourself and find the right pattern to follow.
i wouldnt think about it for a rear disk wheel as the pedal and braking forces really stress the spokes and pull the wheel around, even on the front you will see the wheels flexing as you brake. a front v-brake would be the best situation

What are you on about? It would be exactly the same amount of work/performance as a regular 32/32 or 36/36. All you have to do is not use 4 of the holes.

and what effect will the forces have when applied across the gap left by the spare spoke whole?? the forces will also be concentrated and less distributed equally because of the gaps.

You can't just go and leave out 4 spokes in any random place, you have to have a pattern or the wheel will be all messed up. Finding that pattern is going to be difficult.

And personally I would be more worried about breaking forces on the front wheel than the rear.

I did not say leave them out of 4 random spots, and I do have a pattern that was not difficult at all to find. Simple math guys. 8x4=32(hub), 36-32=4(4 spoke holes not being used), so for every 8 spokes you do in regular fashion, you leave one making the forces evenly distributed.

makes sense to me if i do end up doing it i will do it that way.

yes thats how you would go about it. but ist still a compromise. but the right pattern could play a big part.

i know braking forces on the front r more extreme that the rear, but the pedal stroke results in the rim/hub being pulled in both directions on a dished wheel not just in the one direction.
