Friends: 4 |  Removing Feet off Seat Rails - Drilling is Tricky I removed the mounting feet off the 07 Corolla seat from the junkyard (my practice seat). Drilling through the spot welds has been the hardest. Here's the Corolla seat with feet removed. Required Dremel cutting, and some grinding. Lots of drilling, some chiseling and prying. Not too easy and is tedious work. btw, screwdrivers are great pry tools in a pinch. Next is to remove feet from junkyard Prius seat.   Last edited by cycledrum; 05-17-2009 at 05:27 PM. |

Friends: 4 | Re: Removing Feet off Seat Rails - Drilling is Tricky I've broken several drill bits so far. The steel of the seat rails and mounting feet is pretty hard. Rivets are easier to drill. |

Friends: 4 | Re: Removing Feet off Seat Rails - Drilling is Tricky I'm pretty sure the seat rails and mounting feet are stainless steel or something like that. Makes sense as Solar-Powered used TIG welding with stainless steel rod. Cobalt bits can drill through stainless steel. edit - got 2 feet off the Prius rails ... 2 more to go Last edited by cycledrum; 05-17-2009 at 05:26 PM. |

Friends: 11 | Re: Removing Feet off Seat Rails - Drilling is Tricky I like using the reinforced fiberglass cutting wheels in a Dremel tool for cutting steel. I don't believe that the feet are made from stainless, but they are probably pretty hard as a result of the deformation when they stake the feet and rails together. The engineering term is cold working. |

That seat rail material 'laughs at' Titanium and Black Oxide drill bits. The steel is pretty hard around the spot weld area. The Cobalt bits work ok. Still needed to drill little at a time, clean bit, put more oil, little more, etc... I got decent at it, but it's a bitch nonetheless. Last edited by cycledrum; 05-17-2009 at 08:11 PM. | |
