Edit: I might as well make this my rebuild thread...
Original post; I got side tracked on my Microsquirt build as I have decided, after 11 years of ownership, to finally get my car painted to get her ready for her upcoming 50th birthday. (IMG:style_emoticons/default/smile.gif) Knowing these endeavors can take a lot more time than initially planned, I hope to make it in time... (IMG:style_emoticons/default/wacko.gif) Originally bahia red 73 1.7. The goal is a narrow body 2056 Microsquirt, VW Tornado red, 5 lugs conversion with 16" Fuchs. Front: 914-4 A arms with rubber bushings, 911 3" pin struts, Bilstein inserts, Alfa Brembo, vented rotor, stock torsion bar, 19mm sway bar, turbo tie rods, and 19mm master cylinder. Rear: Drilled hubs, But before I get the pleasure of installing all of these beautiful fresh goodies, I need to tackle the not so fun stuff... (IMG:style_emoticons/default/headbang.gif) I have already started fixing some of the rust issues and will share that progress in the near future but right now, I wanted to post some of the issues i have on the passenger side front fender. (IMG:style_emoticons/default/sad.gif) I have searched and read many of the builds here but I would like some inputs from the people who have gone through this mess. I am trying to understand the construction of the rear part of the fender, more precisely the area joining the front cowling. Below is a sketch of how I think it is made but i would like someone to confirm... Having removed the seam sealer in the upper rear area, I have discovered "this" (IMG:style_emoticons/default/dry.gif) which is not really unusual, but clearly a pain to fix. I am not sure though what I am looking at. If my sketch is correct, I guess the inner rusted layer is from the fender rear bulkhead that actually becomes an inner layer on the rear upper point of the fender by the door and cowling junction. I might be able to cut this from the underside preventing me from cutting the outer surface of the fender. But I would like to better understand what is happening at the junction to the body. How many layers are there from the fender, one or two? Is the metal peeling off at the joint to the body the metal from the bulkhead/inner layer, or is it the outer fender layer? As a reference, this if the situation of the channel, surface rust, but how bad? Is there a way to better know without destroying? Maybe poke with a screwdriver? (IMG:style_emoticons/default/confused24.gif) Comments appreciated (IMG:style_emoticons/default/smile.gif) |

This weeks update:
The door latch bracket deep in the rear fender well needed some help. The cover was rusted on the bottom half. After removing it and threating the area with Ospho, time to start rebuilding. Now with weld through primer and the threaded piece held in place. Good thing i kept on reminding myself to put it there before closing the cover without it, that would have been no fun... For the cover, I elected to make my own with a template I did, shown here on a spare bracket that didn't end up using. I added a lower opening to spray in some rust protection with a tube later on. Then spray painted with weld through primer Then held it in place with my telescopic magnet, ready to stretch and weld it afar with my left hand... (IMG:style_emoticons/default/rolleyes.gif) Moving on to the lower fender corner. The one packed with that darn seam sealer that makes things rust... (IMG:style_emoticons/default/headbang.gif) First the lower part: Repair piece, welded, then finished... Then the front part: same process... Tomorrow, Sunday, day off (IMG:style_emoticons/default/sunglasses.gif) Next weekend, more cut and repair...
