From a tooling point of view everything works perfectly except the cranks but the aluminum bars used are too soft at the first bend of the fork. Maybe they should switch to steel. I did this. For the one-time use price it's not bad, but if you plan to use it over and over again, get a 3/8 steel rod and cut it to thread size and you'll be fine. For extra strength, if you plan to continue using aluminum, get nuts on either side or bars to stiffen it up a bit.
