Ok, the title is a bit melodramatic, but for me, today was a good day.
After breaking a ratchet, a breaker bar, and generally loosing to a two stubborn leaf spring bolts that had been rusted in place I was as my wits end. So the trailer project sat for a couple of months while I stewed over how to get these bolts out without drilling them out. That was something I just wasn't looking forward to. Even my little air-powered impact wrench couldn't budge it. Granted, it's not really for heavy duty work, but it is what I had.
I got a new electric impact wrench from harbor freight for $35 with a coupon and some deep well impact sockets to go with it (20% off coupon for those). Tried it out this morning and ... nothing. Lots of metal bits coming off the bolt head and was about it. I was starting to worry that I was going to strip the bolt. So I looked on this website for some tips. Can't remember the thread, but someone else had used a torch to heat a spring hanger for five minutes before trying. So I got out my little propane torch and set it up to point at the spring hanger. Just standing the bottle on the pavement, and with the height I have the frame sitting on blocks worked perfectly. So I lit it up, put it in place and waited. Longest five minutes Have had in a very long time. When five minutes was up, and a bit of smoke coming from the bolt that I assume was from the fiberglass sleeve, I tried again. It worked! Spun the bolt right out. I did the same thing to the other side and it came off just as easy.
I know it's only a small victory, but i'll take it. Now I can get the new leaf pack ordered and start putting this thing back together.
