What happens if you dont wear a mask? It doesnt stunt your growth does it? Because Bill Hines never wears a respirator mask, but he always is smartly dressed with a cigar in his mouth
You turn grey and fingers start falling from your hands... Cigar is always a good idea, I like them too. It works just like a good quality respirator mask.
Leading is not difficult at all, except on vertical applications since it prefers to stick on the floor rather than the fenders..., but a gastank you can roll from one side to another and beat gravity!
You need tinning butter, this is spread on top of cleaned surface of gas tank with brush, mild heat applied to it. Then use steel wool to spead it evenly on surface. This provide a good surface for the actual lead to grab on. Without it, the lead will not stick, consider it as "flux".
After this application you must wash the surface with baking powder to remove acid residue from the tinning butter. I used Dawn and baking powder, since the surface is "oily". If you dont do this, the acid may ruin your paintjob later.
Then get your wooden paddles out and a jar of tallow, heat paddle and stick it into tallow. The "wet and waxy" surface prevents lead burning and sticking into your wooden paddle. Heat tank surface with propane and apply lead (which is made of 30% tin and 70 lead). Use paddles to control lead.
Once done, its cleaning time again to get acid off surface. Dont expect your wife to bake anything nice for you, unless you let her know that the baking soda was wiped out..
Finally the wide and VERY coarse files are used to file areas smooth. It is relatively easy and files off much cleaner than bondo. Just dont eat any Buffalo Wings or potato chips while working on lead. Not really a good idea...
If you are expert, you dont need any bondo. I'm not, so I had to use some. I did lead work on my chopped car, so I am familiar with it, however this was 30 years ago. Inspite of that, I managed to melt the lead and best of all, most of the lead was found on the tank, not on my toes.
Here's a pic of my old Mini (RIP) which was chopped 3" in front and 2" in rear. This picture was taken before I put fiberglass flip front on it, shaved all roof lists off it and sectioned it another 2". Thats when the state inspection told me to take a hike. I complied and later moved to USA....
This is how the Mini was supposed to look like, gull wing doors (they were THE thing in Europe, during 80's), flip front, widened body, chopped and sectioned, shaved lists, V-6, rear wheel drive etc... Well, I almost got there, until the darn goverment inspection told me it would never be approved on road due to too extreme modifications. it was one of the first chopped cars in Finland...
looks like my drawings have not changed too much in 30 years either? Still nuts about anything that spins around makes makes a lot of noise...
This was in 1983, but we're getting off track here from the 2 wheelers, I just got a bit exited about lead work... If I lived another 30 years, how bad can it be? I most definately did not use any respirators in 80' and often crawled out of the smoke filled garage all messed up. Other than that the 80's seemed to be just a blurry image and not much memories left, it's OK. That could have something to do with excessive beer drinking, but we dont want to go there...
