Getting wheels rebuilt - huge cost!?

[K2-K6]

Because the thinner part is calculated to take the strain needed to do the job, the thicker ends allow extra material to accommodate the threads or the bent end without compromising the core specification.

Also (as with waisted bolts and studs) the load is more evenly handled / spread along the component and if designed properly you don't get a high stress point which occurs with a straight component at the bend or where the threads end.

Save weight, the middle bit is under less stess than the bits contacting the hub or rim - rim ends have threads cut into them, other end has a bend and needs to spread its load over an area of alloy hub which is softer. Might shave a few grams off the wheel, probably looks nicer too. ( looks being very subjective as to what is nice )

In addition any decent spokes will have the threads rolled (could be called cold forging)  into them rather than die cut which would destroy the material integrity and reduce its tensile capacity, just what you wouldn't need in a spoke.

7 weeks at central wheels!!!!
I need a complete rebuild, rims, spokes, and shot blasted hubs, but i'm not waiting 7 weeks.
i will call them in the morning and see if this is their lead time at the moment , if it is does anyone know of anyone else in the Birmingham area that can do it quicker please?

 I suggest you split the job into 3 stages and/or suppliers,firstly rims and spokes,then blasting the hub and polishing/painting,
the assembly,

 can you paint/polish the hubs,and build the wheels,or would you need to source it?
just contact ALL the wheel/rim/spoke suppliers for quickest lead time

Wheel building is easy its what else you want done
