I was thingking, maybe you know how it might work... having a machining co make me a 135mm axle out of Ti.
I was discussing it with Tom of Harris Cycles... he could have used spacers on the Harris hubs but it would leave about 2.5mm of unsupported axle. But he also said that he never had any bent axles due to this. I just didn't want to take the chance.

139 seems wide. 135mm is the widest I know and it is very common on mountain bikes. Measure it like this.
Regardless of the actual spacing, changing it is very simple. Just remove the outer nuts and place spacers on the hub axle. If your wheel is dished symmetrically then just put 7.5mm of spacers on each side to go from 120 to 135mm.
But... If you have a mtb frame with an OS 73mm BB shell, you will have chainline problems if your hub has a 42mm chainline (most likely).

Oh yes... You will probably need a longer axle. Make sure you take the same diameter and thread pitch. And learn how to adjust cup and cones, if the hub has not cartridge bearings.
And about chainline... If the BB shell is 68mm, an option is a 115mm spindle (square taper) and some older double shimano crank with the chainring in the inner position to set the chainline at 42mm.
