Re: 1920 "F" Project
Hello folks. I have not done an update for a while because I seem to have had lots of things going on but nothing finished. However things are now coming together so first I will do a tank update.
Before that though I have a question. How much oil do you put in the crankcase from dry? Is 2 pumps of the hand pump correct?
Now the update.
As you may know the bike came with 3 sets of tanks. The original tanks are like swiss cheese so are not a viable prospect for repair. The 1916 tanks are not so bad although one needs repair it is not as bad as my original 1920 tanks. However I have put them away in the loft for now, if anyone wants them please pm me.
So that leaves the 2 red tanks. I had already taken the paint off one tank, here is a picture from earlier on in this thread

This tank was quite good but had some holes but these were confined to one area. So I decided to see if it could be fixed. I didnt have to worry about paint so I decided to take it apart. In case you were wondering how these tanks look like inside here is mine

The yellow stuff is the gum left from old petrol.
Here is the bad bit.

Here is everything cleaned up.

You might notice something in the bottom right corner of the above picture.
Thats because it is after a new piece has been welded in. I would like to say that I welded it but I am still very new to TIG so I got a friend who is a professional welder to do it because the metal is 22 gauge.

Here is the bit that was removed. The rest of the tank is fine.

Once I had re-soldered it back together I pressure tested it. I had a leak or 2 on a couple of soldered joints but they were easily fixed. Unfortunatly I didnt take any pictures of the re-assembly
