Bicycle Mechanics - advice on trimming down axles

i've got some surly track hubs with longer (solid) axles (to accomidate installation on a frame with 130 spacing, i'd guess), but i've got them on a track frame with 120 spacing and find the excess axle sticking out the side to be a bit obnoxious.

i assume i can safely trim these down, but what's the best way - is a hacksaw going to take forever? should i seek out some kind of grinder?

thanks

get a shorter axle. swapping them on surly hubs is a breeze...

Are you using full size track-nuts rather than simple bolts? If not, switch to them, then decide how long you need the axle.

thanksYou could already have had it done with a good hacksaw.

Just spin the nuts *on* before you cut so when you undo them, you clean up the thread end a bit. A bit of dressing with a bastard file might also smooth off the rough edges before the nuts come off.

Best thing is to determine how much total to cut off, remove the axle from the hub and cut it all off one end. Use a bench grinder to bevel the cut end slightly to clean up the threads and make it easier to start the nuts. Then thread a nut on from the uncut end and work it off the cut end to clear any burrs from inside the threads.

If you muck it up, then just get a new axle. No big deal.

That's assuming the axle is threaded all the way across.

Yes, it assumes that when you are finished you will have threads enough for the cones. Otherwise you need to cut both ends.

just sawed the sucker down with my dremel tool in about 2 minutes. left a few mm extra on each end and beveled the edges down smooth and nice... no sweat.
