youngblood Posted April 22, 2009 Share Posted April 22, 2009 So i ordered me some frame rails the other week for my car. i thought it wouldn't be that difficult it install them but i keep running in to more rust and problems i didn't expect. I work form 5 to 11 pm almost every day so I've been doing a little work at a time when i can and i'm now about a week into the project and i haven't even got on frame rail on yet.

jt1 Posted April 22, 2009 Share Posted April 22, 2009 Take your time, stick with it, and do a good job. If you get in a rush and halfass it, every time you jack up the car and see your sloppy work, it will piss you off. jt Quote Link to comment Share on other sites More sharing options...

youngblood Posted April 23, 2009 Author Share Posted April 23, 2009 i started cutting out i obvious rust holes in the bottom of the frame rails but then i'd stick my hand in the open part of the frame rail and the was more rust under there so i kept cutting untill i cut the whole bottom of the frame rails out. i left the sides and just cleaned of the rust and paint ith my grinder.

youngblood Posted April 23, 2009 Author Share Posted April 23, 2009 Then after i started cutting out the frame rail i start to find rust hole under them. The metal under there was too thin to weld to so i had to find so scrap metal to patch it up. Quote Link to comment Share on other sites More sharing options...
youngblood Posted April 23, 2009 Author Share Posted April 23, 2009 Keep in mind i have no experience with metal work and for welding I've hired me good friend who just bought a bid miller mig welder. he's not really a profetional or anything but we're doing are best. I went and got some scrap metal from an broken washing machine and i had to cut out a maxi pad shaped peice of metal with my angle gringer and a cut off wheel. so now it seems like my car is part washing machine. view from the inside Quote Link to comment Share on other sites More sharing options...
youngblood Posted April 23, 2009 Author Share Posted April 23, 2009 i also welded up the inside of the framerail seams for extra strangth. i painted the inside of the frame rails with rusto spray paint and the silver paint on the out side is weld-though primer.

Always wondered EXACTLY how the Bad Dog rails fit on the Datsun. With your photo it becomes VERY obvious. They are meant to slip over and weld to the existing rails. The RH rail on my 240Z is bent upward. Then the only way is to remove the spot welds and cut out the bent section. Straighten same, straighten the floor and weld the original rail into place. Then apply the Bad Dog rail over original and weld it in. Quote Link to comment Share on other sites More sharing options...
youngblood Posted April 23, 2009 Author Share Posted April 23, 2009 yeah a tip for you guy who are going to do this. paint the underside of the frame rails with high heat paint because as we were welding, a lot of smoke was coming out from under the frame rails and i'm pretty sure it was the primer burning of from the heat.

youngblood Posted April 23, 2009 Author Share Posted April 23, 2009 To anyone who's ever done this on a 280z before i was wondering if i should drill a couple of hole in the bottom of the frame rails for drainage reasons. i tried to seal the hell out of the inside of the old frame rails to prevent moisture from getting in there but the original frame rails had some drain holes in them so i was thinking i should do the same with these.

DeleriousZ Posted April 23, 2009 Share Posted April 23, 2009 make sure you've got a fan going when welding underneath the car. either that or wear an activated charcoal respirator. those fumes are not good for you. Quote Link to comment Share on other sites More sharing options...
youngblood Posted April 24, 2009 Author Share Posted April 24, 2009 so early today i finally got one rail on. the welds arn't perfect but it's stuck on there pretty darn good. Now I'm working on the other side i had to patch up some rust holes on the other side with some more washing machine metal. now i official have a hybrid z, part car, part washing machine.

youngblood Posted April 24, 2009 Author Share Posted April 24, 2009 I kind of ran into a big problem just now with my passenger side frame rail. As you can see the floor pan has a curve to were the inside part of the frame is much taller than the outside. when i fit the bad dog up under there it fis up real nick on the outside but there is a huge gap on the inside. and then were the tale end of the frame rail fits up there is a huge gap. outside fits up real nice as you can see the inside and the tale end of the frame don't fit up quite so well. Has anyone who's done this before on a 280z ran into this problem and how the f#*k do i fix this problem? Quote Link to comment Share on other sites More sharing options...

youngblood Posted April 24, 2009 Author Share Posted April 24, 2009 I'm thinking about putting in a pice of metal like this but it still wont be that strong because it's just washing machine metal. Quote Link to comment Share on other sites More sharing options...
