Sheet metal work to install the fuel tank

I was trying to repair a part of the trunk floor around the fuel tank using the sheet metal I got from a person of the repair shop.  My purpose was just to add some patches for the reinforcement because I had never done the sheet metal repair and didn't have a skill.  My only experience for the sheet metal work was to make the dustpan in a class when I was a junior high school student.  I liked that class and was good at, but it was 32 years ago.  I didnt know how it would be.

After watching the trunk floor for a while, I started making the pattern paper.
I found some moderate thick papers at my house.  And I attached it on the repair part and cut it to fit the shape of the flange to be repaired.


Next, I copied this pattern paper into a sheet metal and cut it.
At first I tried to cut it with sheet metal scissors, but it was difficult because the sheet metal had 1 mm thickness and it was too hard.  Therefore, I decided to use the disc grinder.  I aimed close to the pattern paper line on the sheet metal as much as possible, and cut it with the disc grinder carefully.


I was a bit nervous because it was just 2nd time for me to use the disc grinder.  But it went well.

After this I adjusted the shape with scissors and a file.


The sheet metal became like this.  It was not bad!


Next was to bend the sheet metal using a vise and a couple of wood pieces.


Then, I formed the sheet metal adjusting to the shape of the area to be repaired.


Finally, the joint part of the wall and the flange was soldered.  I knew welding would be better, but I didnt have a welder.  I thought solder was okay because the base flange was still strong.


The formed sheet metal would be fixed on the flange like this. 


This was the work for this day.

Next work would be…
-       Remove the rust and old paint at the body side to be repaired,
-       Fix the formed sheet metal on the flange with steel rivets and JB Weld,
-       Paint the remained POR tank sealer on the repaired parts to prevent the rust.

It was a sheet metal work for the first time in 32 years for me, but it was very interesting.

Tip to repair rubber parts

I disassembled the rear axle before.  There had been no progress on it because I started the repair of the fuel tank during my summer holiday. While painting the fuel tank , I repaired the torn rubber boot of the parking brake wire. I guessed it didn ’ t cost high because it was small rubber part.  But I wanted to try the repair method I read on the magazine article before. This was the condition before the repair.  The rubber was torn apart and separated almost. I used this self-adhesive type butyl tape.  I pasted lots of small pieces of the butyl tape on the back side of the rubber boot.  As time goes by , these tapes would melt and stick together.  After this I applied plenty of adhesive “ Super X Black ” on the rubber boot.  On the magazine of MOTO MAINTENANCE , I read the article that the motorcycle seat was repaired with this method.  So , I wanted to try it. After drying 1 day , it became like this....

Brake master cylinder overhaul #1

I started the overhaul of the brake master cylinder after the clutch slave cylinder. This day ’ s work was removal and disassembly of the brake master cylinder. My “ onboro ALFA ” is early type ( Mk. I ) 1750GTV RHD.  The brake master cylinder is made by BONARDI and it is installed on the frame under the floor together with the clutch master cylinder ( this is made by BENDITALIA ) . Regarding the removal , there was a little try and error. ( 1 ) Remove the pipes Then , I tried to separate the linkage rod connecting to the brake pedal.  However , the fixing nut was so hard that I changed the process. ( 2 ) Remove the bolts fixing the brake master cylinder on the frame. ( These bolts were also fixing the clutch master cylinder penetrating the frame. ) ( 3 ) & ( 4 ) Separate the linkage rod from the brake pedal , and remove the brake master cylinder together with the linkage rod. ( The linkage rod and the pedal were fixed by a split pin. ) ...

Fuel pump (The original blog was written on 15th Aug. 2007)

Although the gas was refilled , the gas didn ’ t come to the carburetors.  The electric fuel pump was working , but it still did blank beating.  I replaced the pump soon after I bought this car…but it was about 20 years ago!  So , I decided to replace the electric fuel pump to new one , and to change the location of the pump from the engine room to the trunk room ( because for the electric fuel pump to push the fuel is better than to pull the fuel ) . I bought the Mitsuba electric fuel pump , fuel hoses and a fuel filter by auction and installed them in the trunk room.   ( The wiring is tentative.  But I am ashamed because the trunk room is so dirty… ) However , even the new fuel pump was working well , the fuel didn ’ t come.  I guessed that the inlet of the fuel sender unit in the tank was sticking.  I remove the unit from the tank and found the rusty unit and its inlet was perfectly blocked by the rust ( I forgot to take the pictu...
