Ive wanted one of these for along time, but with a few exceptions the old hot wrench does the trick.
Unfortunately I had one of those exceptions this week. I was replacing a rear subframe on an econobox. The fuel tank was molded into the subframe, all one assembly. It wasnt a bad job really except for the junkyard part it was replaced with was in rough shape. The bolts for the toe adjustment arms were frozen inside of the bushings. These were within cm of the tank.
aafter screwing around with them for a few minutes, i ended up getting the saw-zall out and cutting the bolts. I think if I could have heated the bolts and then quenched them it would have freed up. One of them came out afterwards just from the heat/vibration from the sawzall. If it had been in the car, there would have been now way to cut them out, so heat would have been the only option at that point.
Considering Im getting out of the biz I dont think I will ever own one, unless I pick one of these up instead of a torch outfit for the house. I have all the tools that a torch already does so its really a wash either way
