Step 1: Parts
-crescent/ adjustable wrenches
-two bicycles, nothing fancy (possibly a smaller frame for the stoker if you'd like, and if you're picky and want certain cranks, go with frames with square/ taper BB's)
-crank puller (optional)
-basic bike tools
-probably some other stuff I can't remember right now.
Step 2: Wheelses
using a combination of wrenches and or pliers, do what you can to remove the axle from the front wheel that you just took off. we're discarding it, so make no special effort to keep it in great shape, though I highly recommend keeping the innermost washers in the best condition you possibly can.
we're also removing the rear wheel's axle, so once again, try your best to remove all the washers while keeping as much as you can in tact. a workbench clamp is very helpful in such removal, as sometimes certain sides get stuck. I do not at all recommend using a pair of plyers as a clamp, as you'll strip the threading on the axle easier than you can possibly imagine.
anyhoo, just make sure you have all the washers and nuts from both hubs aside from the ones that press against the bearings in the rear, because they'll probably be a bit of a different size.
the whole point of this step if you're handy enough and don't feel like reading, is that we're putting the rear axle in the front wheel. it's longer, and we need that extra bit of length.
I haven't tried this with a quick-release axle, though I'd be surprised if it didn't work. under the same token, why would you need one?
