Congratulations, both wheels are off, on one I had to cut the axle out of the chassis so I could get it in the press to get it off, ended up taking me a couple of days. Next question is how are the threads on each end of the axle? I find most are usually damaged by people hammering them trying to get the wheel off. Wheels come up from time to time on ebay but not that often. You have a couple of options, depending on how much slop there is in the hub to the shaft, you could cut some strips from a coke can and wrap it around the shaft, then hammer in the key and force the wheel back on. As long as it is tight and there is no movement then it should be ok. The second idea is one I have never tried but wanted to and that is grease the hub up and let the wheel float on the axle giving you a single wheel drive which will vastly improve the steering. This would only be suitable if you are using it on flat ground as a single wheel drive may not get enough traction or braking on hilly ground but the braking on these is near useless anyway. The advantage is with the heel and toe you can use that for braking, but once again you would only be using one wheel for braking. Just thoughts throwing it out there
