It's probably me, but assembling this thing with the equipment it sent is like summoning Jesus Christ to my garage, and no matter how many times I attempt to do so, unfortunately, JC does not appear. It is an absolute nightmare, and if you're not a mechanic or someone with additional tools at your disposal, I would encourage you to buy a more functional piece of equipment. I have tried and failed now three times to assemble this hunk of crap, and it's been a battle of attrition, that frankly, I am currently losing.
