I purchased the metal crutches from the local thrift store. They were $2 per pair. Try to get two pairs that are as close to identical as possible. (You might consider buying an extra pair that fit you in case you need them some day. A few years ago i tore a muscle in my leg and was charged $80 for a pair.) Remove the handles from the crutches. The bicycle rims don't need to be perfectly straight - the ones i used were in horrible shape. I didn't bother trying to true the wheel - i wanted to see if this idea would work first. You can probably get the wheels and inner tubes at any bike shop for free. You'll want to remove the axles. Wash the grease off of the hubs.
