I went to go get it done today. Shop told me it was going to take some time; "them springs are pretty hard you know" <img src="/forums/images/graemlins/rolleyes.gif" alt="" /> They start to drill through the overload using a little bit of oil, make it half way through and the guy decides that he can't do it. It only took him 30 secs. to do half... I asked if they were using a carbide bit; "just a standard bit." I asked if they wanted to try using a better drill bit, said they didn't want to risk it. Said that those drill bits are $50 a pop.
I told him that I bought one from Lowes for $17. Reply - that bit would only last long enough to drill out a few holes. That's all I need done - a few holes. (sorry need to vent)

Anyway, the other local place said they could do it with a plasma cutter. Do I want them to use a plasma cutter on my springs?
