Flydaddy,
You can't have enough clamps! I use clothspins for some things, but most of the time the jaws are to close. I found a great assortment at Widgett Supply and they are reasonablly priced.http://www.widgetsupply.com/clamps/clamps.htm
They work where the clothspins just won't. I bought a bucket full along with 7" clamps.
I know the budget thing can slow you down but having something cure crooked can really jerk your chain.
Just another resource. Keep us posted on whatever you do.
