Sill replacement. 1990 Mk2 Rev 1 T bar.

Post by BrianDeacon » 26/01/10 20:54

Hello All.
Have been reading TrevMk2's great work on sill replacement. Now started to follow his lead and tackle mine. Starting at the drivers side have cut along about an inch below the door. This done with an angle grinder and cutting disk as its quicker than using the nibbler.
Then drill out all the spot welds along the lower flange. These can be seen more easily of you shine an inspection light along the sill. I drilled through each one with a 1/8 drill then drilled the weld with a larger drill just through the sill and not all the way through the flange.
The T Bar has additional stiffening with a vertical flange behind the sill. This is spot welded to the sill just on the curved surface above the lower flange. Shining the light you can just see the weld spots. These were drilled out in the same way.
The inside structure at the rear is well corroded. So far have cut out all the bad stuff and reprotected until I can start to fabricate parts.
There is a good article on how to remove the side vent panel which must be done to complete teh sill replacement. Its on the "know your MR2" pages.
A waiting Astra Mk1 sills now to get the next bits done. Could not have started this without Trevs good info on this site. Brian

Still waiting for the new sills to arrive. Have cleaned the exposed structure and coated in rust removed gel to keep the weather out! Some more pics added to show the "hidden" rust damage.
Having to do this in the drive so hope the snow doesnt come back!

The front of the Astra Mk1 sill fits really well. It has been joggled to fit inside the original sill piece that was left in place.
The inner T bar web will have angled pieces welded to it and the lower flange. These do not need to be shaped to allow water run off as the web itself is shaped and will leave gaps between the new and old metal.
The rear of the sill is more of a problem. The original structure is still good and I did not want to cut this off. But the new sill profile will not fit. Still undecided whether to reprofile the sill at the back end, or cut of the support structure and make a new piece.

Bad weather has prevented much progress in the last month. Now going to be on a contract for three weeks so not expecting to start welding parts in until April. Will post some pics of progress then.

Still in KL with temp at 34 deg so welding MR2 sills way at back of mind. Will have to get a move on though as going to unsorn the car at the end of this month.

Well work has beaten me. :sad: I just cannot find the time to finish this project, and must have the MR2 back on the road by September as we will be using her to go to the Circuit De Ramparts in Angouleme, France. She is has now been transported to VRS in Iver to have the project finished. They will take some photos as this progresses which I will upload onto here. Brian

Well sill replacements complete on both sides thanks to VRS of Iver. Really good job and the Astra sills fit very well. Car MOTed, unSORNED and back on the road for the summer.

Good work Brian its a shame you didn't get to finish it yourself as you were doing some well thought out and executed work.

At least you can have fun with it now she's all good.
