Do you not have a bench grinder or a right angle grinder handy? That would be quicker.
I guess I'm spoiled. I've been buying tools since I first went to work. My buddies were buying golf clubs and skis and junk like that (I did have a nasty bowling habit that was expensive but I never had the patience to devote all the time it takes to try and turn pro) and now, in my mid 50's I have two lathes, one with a small mill that works if you ain't greedy and don't crowd it and a TIG welder plus all my hand tools right out in the shop.
If you have any kind of a grinder handy you can knock this thing right out, and then order some bolts later if you want to.
Glad you are sticking to it. God hates a coward. And a quitter. Sometimes, you just gotta grind on it (no pun intended) until you make it work!!
