So im going to a blacksmith collectors "yard" tomorrow to sort through and pick stuff out that i would like to purchase. he has plenty of small working hand cranks for $75 and alot that dont work for im hoping somewhere around $20. What are some things i should look out for? i talked with turbo in chat today and he recomend that i take some pliers, screwdrivers and an adjustable wrench wtith me. Then he had to go, once i get ahold of one that is frozen up or doesnt work, what do i need to look for as far as making sure its worth the $20 or so dollars?
