I used two nails and a screwdriver between them when little josh broke my tool..
they're cheap, you should just buy one sometime..

I probably should just buy one. I'm kinda poor from being unemployed for 3 months. maybe when I get my first paycheck next week.
I did get it tight though. Just jammed a large wrench between the tensioner and frame rail to keep it from moving when I tightened it.
