  1. Today was the first day that my Z was turned around in the garage. It has been over 1 year since the restoration started. During that time, I was looking for another 240z or even a parts car. Because of our high humidity and being surrounded by saltwater, the 240Zs that I looked at were real "rust buckets". Only consolation that I have is that nobody here (that I know of) has went through such a complete restoration. The Z finally turned around in my garage. Only the right side of roof, rear panel and right quarter left to strip the paint off. Managed to finished the upper left quarter panel patch. The dip rail was made of 20 gauge metal. urethane seam seal will seal the drip rail after epoxy priming the whole car.Bottom view of patch Interior view of patch For extra protection, I used a 1/2" Blair hole saw to drill rust proofing access holes. A bendable magnet is used to recover the drilled out piece. The 1/2" plastic plug will seal the hole after rust proofing treatment is done. The rustproofing hole is just forwarded of the repaired area. Also, it will allow rust proofing of the hatch hinge area(another corrosion point). More access holes will drilled in potential corrosion areas through out the car. Rust proofing will performed only after final color painting . Thanks again for your praise. Most people do not realize how much work there is for 47 year old vehicle restoration.
  2. This weekend. I started on the corrosion on the upper section of the right quarter panel. This area was little heavier gauge(about 20 gauge) but had to be removed. The removed area, in this case, was about 5". Just the left of the front cut is the connecting area of the quarter panel and the roof. This joint was welded then lead soldered at the factory.All of the lead solder must be removed before work can be done. When this car was manufactured, using lead for the roof joints was common practice( even on US made cars). A template was made to provide reference points when reconstructing this area. In this case, the template was copied from the opposite (right side) and image reversed. The drip rail patch was constructed using several paper templates. Note: both front and rear ends of the patch have extra material to allow welding to original metal. If you notice that I marked directions on my work, it is because it is easy to get confused and place the patch the wrong way. The lower portion of the patch welded the body. Note: The drip rail is made taller and will be grinded down after everything is completed. The seams in the interior of the patched area were tack welded to increase strength. Then painted with welding primer.
  3. Managed to get in three hours to work on the Z. I installed the dog leg panel from ZDepot. Photo of underside of the dog leg panel.
  4. I almost made a mistake. When I was watching a video of 240z replacement of its rocker panel, I realized that my rocker panel had to be longer. So I constructed a new longer rocker panel section. This is a photo of what I can up with. Basically it is just longer than the old one. But the new rocker also had to be "capped" at the rear. Interior view of the new rocker panel. This pics shows the rocker panel welded in place. Now, templates were made to construct front upper and side step for the dog leg. This required three separate metal pieces to make this complex shape. Used a oxygen/acetylene torch with 1/16" steel rod as the metal was so thin. The finished front upper section of the door leg( three separate pieces of sheet metal welded together). The welded section was then welded to original dog leg and then painted with welding primer.
  5. After waiting for my replacement dog leg panel for a month, I canceled my order with them. I then ordered the panel from Z Depot instead. It came in one week. Now I can finished up the corrosion repair. I welded in the inner reinforcement panel and painted with welding primer. Now to fabricating the upper portion of the dog leg. First , a template must be made . Using a metal shrinker , the upper dog leg portion is created. With the upper portion mocked in, the next lower stepped area can made. The picture below shows the dog leg and this stepped area together. Next, the gap between the rocker panel and the dog leg must be filled. Another template for this gap is made. There is six separate bends that required. Even with a template, mistakes can happen. Just straighten it out and rebend it. Sometimes even with metal brake, you have to use "red neck" technology to get the job done. Almost finished, the patch and dog leg ready to be welded. The wheel opening end won't be welded yet as the new flare size has yet to be determined.
  6. Low Cost Rotisserie

    After rotating the car to the horizontal position, I attached the two caster cross members. Pushing the car around was fine but I noticed that the rotisserie was wobbly when moved. So I decided to add a 1 1/4" galvanized conduit between the two ends of rotisserie to solve the problem. Two mounts were made to hold the 15 feet of 1 1/4" conduit. Two 5/16" x 1" lag screws held the mount to the cross member.A 3/8" bolt with welded nut holds the conduit in place.
  7. The quarter panel dog leg section is still on back order from the manufacturer so I just do other body work for now. Next, the old metal reat fender flares must be cut out with acutoff wheel and air saw. Additional flaring work must wait till the new wheel and tire configuration is determined. Inside view of cut out fender flare The left rear quarter panel was stripped of previous paint jobs (about three) plus the original primer and color. To aid in paint stripping, the addition paint layers( besides factory ones) can be removed with a single edge razor. In this case, the top 3 paint layers came off in one' thick piece leaving only factory color and primer left behind. Since I had some extra time, I decided to add additional lights to my garage area. Two 4000 lumens Led Shop Lights on Amazon for only $30 each were installed. As you can see the two LED lights really brightened up the garage. I will probably add a couple more to light the sides of the car when I am painting.
  8. Low Cost Rotisserie

    Returning to Low Cost Rotisserie topic after almost a year. Preparing my Z for media blasting. I decided to work on the rotisserie. As the car will probably be in the normal upright position for the most of the rest of the restoration, casters must be added to provide easy movement. Utilizing two 2" x 2" x 1/8" right angle shelving brackets formed into "U" shaped channel support between the two vertical supports of the rotisserie. Two 4" metal casters were added to bottom of the channel. Support channel is about 88" in length. Each side of the channel us attaches to the rotisserie with six-5/16" x 1" lag screws on both sides. Back view of front caster support channel. Each 4" caster has a load rating of 250 lbs. Pic of rear caster support channel These caster channels will be slid in position/ bolted down after car is in the horiziontal postion and jacked off the ground. These 4 swivel casters will allow the vehicle to be turned completely around with ease. Cost of casters was $10 each-Home Depot and shelving brackets were free(dumpster diving) A 2" X 4" board was cut down to fit in the center of the support bar and bolted to frame with four 5/16" x 2" lag screws. This was to provide additional strength when floor jacking on the bar. ' Overall view of addition to support bar
  9. Returned Sunday from a convention in Las Vegas but managed squeeze three hours of Z work time in. As I was waiting for the front lower quarter panel leg, I decided to pull out two dents on the same rocker panel. To do this, a 110vt stud gun was utilized. The gun spot welds copper studs to the damaged area then the sliding grabs and pulls the dent out. Pic of crease on rocker panel. Another angle of stud pulling. If the repaired becomes "high" , there is also a shrinking tip that can be used. This flat tip will heat a small area "red hot" then tap this area with a body hammer down. Next, "quench" the area with a wet rag. This will create the shrinking action to occur and lower the area. Repaired area after grinding with#24 grit paper Pic of the other dent repaired with stud gun
  10. Back to rust repair-on Left Rear Rocker Panel. First pic shows all the dirt and rusted metal that was cut out. Pic of area that was worked on. What made this job harder was the rustproofing inside the panel. Scrapping took most of off then removed the rest with lacquer thinner. Then the area was sandblasted clean. My new curtains helped as they kept the media spreading even further. Rear view of repaired area. Also, found additional rust on wheel housing. Note-raised area above seat belt anchor bracket After sandblasting the area. Made temp[ate for panel patch. Note: the raised area had to be hammered formed. This was necessary so the patch would not touch the seat belt reinforcement plate. The factory plate has similar raised area. I also made the wheel housing side one piece to prevent future leakage. Patched the wheel housing area, I drilled a 1" hole near the seat belt bracket so I can rustproof this area after painting the car. 240Z usually had corrosion problems on front and rear of left/right rocker panels. I think more though rustproofing and urethane seam sealing will do a better job against corrosion.
  11. Camaro IRS swap Richard, Thanks for the Rapid Answer. Before I heard about some guys using Ford 8.8, I was thinking about putting in the whole rear suspension from a late model Camaro and basically narrow it to fit. That way you get a beefier wheel hub( although 5 lug). Also, it would limit machine work to shortening both axles. Most of late model cars use an independent rear with four bolt mounting system so it could be possible. I was looking for a wrecked Camaro so I could take measurements to even see if this swap was possible. But I got diverted to the paint booth build and still got more rust work to do. Anyway, somebody might already done the swap already. Toolman factory Camaro IRS suspension
  12. Richard, Looks like a nice installation! Roughly how much did it cost you? I am considering it for my car. What rear gear ratio are you going to run? I would guess about 3.90 with a T-56 trans. Is there a lot of these swaps out there? Toolman
  13. Picked up four intake filters 20" x 20" and four exhaust filters 20" x 20". Fabricated a metal frame out of some right angle 1/8" vertical shelve poles. I hung a 10" strip of sheeting about 3" in front of the curtain cable by stapling to the ceiling. The gap was necessary to allow curtain movement but be close enough to seal the curtain to the ceiling. With the fan running, you can see the fan pressure is sufficient to seal the curtains. Outside view -The garage door was lowered to the #1 exhaust filter frame and #2 block off frame. Inside view of exhaust filters The booth airflow test consisted of hanging thin strips of plastic sheeting in the air to observe its movement. As you can see, the test strip near inside exhaust filter is being drawn against the filter-indicates sufficient airflow leaving the booth. . The outside test strip indicates outward airflow also. After more testing, I found one of the exhaust filters had pushed out of the frame. So I added some metal screen on the inside to stiffen the exhaust filters. That seem to solve that problem. I spent a little more than $200 of materials to build to this booth( mostly from Home Depot). This booth suits my needs and requirements. I hope you guys found its construction interesting. Added screen wire to stiffen the filters.
  14. The photo shows the fan duct folded up and held in place with 3" wide strap. The strap is duct taped to fan body and the other end is velco attached to opposite side of fan. Extra grommets were added the area above the fan for more support. When the curtain is open and aligned with the fan, it looks like this. Once the fan is switched "on" , the incoming air pressure basically seals itself in the curtain wall. It works like those inflatable bounce houses for kids. When finished using everything folds up nice and neat.
  15. Decided to enlarge the booth size from 1 1/2 car to 2 car size for various reasons: more room to paint, left side curtain closer to fan and easier to use. Also, now the garage door does not have to be closed to utilize the curtains. The following photos show the improved booth design. After trial fit, 24" was removed from the bottom of the curtains. 4" was allowed on the bottom to be held by a 2 X 4. Made a duct out of scrap sheeting to connect fan to curtain. No sure how to attach duct to curtain. Might try putting the duct hose into another hose section attached to the curtain. Left curtain must also be modified for fan to blow through but still allow to be folded up.
