Hi just wondering if any one knows where or the proper name for the compound used with led.

Thanks

Oldsmaniac

Eastwood lists tinnng butter for tinning and tallow for anti sticking of lead to wood paddles...

It was called "tin quick" back in the day came in a can was applied with a torch and brush.

I use commonly available flux. And while I haven't build any lead sleds I do still own one of the first cars I did 20 years ago. I think cleanliness is more important at that stage than anything else. Cut your substrate with a clean abrasive ( I use 80-180 depending on what finish level I'm going for) then flux and flash it with your torch or iron. Ready for lead.

Thanks guys have some coming

This is for my door there are a bunch of small dents/ wrinkle on the edge and I can't get to it as it's a seam area so we are doing the led work instead of bondo

We tried the solder/w flux but it wasn't sticking like we wanted to in the two holes we were filling

I'm wondering if silver solder would've worked ? If you have the tin Quick coming then that's much easier to work with afterwards.

oldstata

Silver solder is 100.00 a lb tho lol the tinning compound and led was only like 50.00
As silver was my next if I couldn't find it went to five body supply stores and they all told me we have the led but never heard of the compound so frustrated

muratic acid works well. be very careful with it. caution on the edge metal too much heat will raise the panel next to the edge crimp. i used to do the lead work at fisher body, if you need some help id be glad to help you on here.

Oldstata. Personally I would weld those holes closed, but it's up to you. If you want to, plug style weld them and not too fast as to not warp the metal. However, if you do want to lead them, then you need to drill them out just slightly larger than they are and then bevel them (by hand with a larger drill bit), and use a copper or brass backing to absorb the heat and not stick to your filling material. Then fill it with lead and file or grind it and do your finish work.

oldstata

The holes you see are trim holes. There was two small rust holes that we started to fill with the solder, but it didn't stick to well it was rusted from the front from rock chips on the edge they were threw the skin but not the back part of the door

Ah, rust pitting can be difficult to clean and get lead to stick to. As oldolds88 said muratic acid works well or a spot blaster could be used. If your using solder go with acid core, it's specific for autobody and available at the paint store.

Here is a few pics of the solder filled holes I will be doing led work near the edge to fill some dings

tap the edges of the hole inward so it is tapering. that small hole should be half dollar size when tapped in. tin around the area to the size of about 3 inches,that will give you plenty to work with when finishing it down. hand finish ,so that you can creep up on the final finish. if you get agressive with the grinder the finished lead will be lower than the base metal. safety first,gloves, resperator, and goggles. i use a 70/30 blend 70 %lead 30%tin. soft,easy to work and genuine oldsmobile. the paddles i use are made from birdseye maple,i put a cross hatch pattern on the face of them with a hacksaw blade. it's to move and tamp the lead when its being applied. rust will not tin,it has to be blasted or cut out and a backer piece welded in if the hole is bigger than a dime. paint,dirt,and filler will not tin.if its tinned correctly,lead will stay for a very long time. i use beeswax on the paddles to keep the lead from sticking,oil will work but i prefer the wax. if the lead isnt tamped down, or there is dirt,and debris in the lead there will be pits in the finished piece, if they arent too bad you can use spot putty to fill them. if you want i can give step by step. or i can bore everybody with babbling. if you cant tell, i like doing lead work. its fasinating to me.

oldstata

The holes had the two seams so there was metal behind it I spot sand blasted them

I do have a body guy that has done this teaching me a few tricks . I have been metal wiring doors forward I think I've done 80% of it my self

If you would like to see more look up my build

Oldstata. Glad to see your making progress here! However, as a word of caution those hard edges around your lead work are an omen. Any edge in lead work or welding is a "hotspot" for a crack, that contamination will hide in there just as rust does. The problem is you won't find out for months or years after you have $$$ on top. Then it takes time plus money to fix it. I would re-flow it/fill it until it is level and you will have peace of mind to boot. And kudos to oldolds88! You sound like an experienced lead man! I've never had the stones to try oil or old thick wheel bearing grease on my paddles, just too many ways to make a problem IMO.

Got the tinning butter today not sure what to think about east wood just yet half the tub was spilt all over the box. I need to call them it's less then half full

Any how, wasn't what my buddy was expecting as he used a powder I guess back in the day
We are going to give it a shot any ways

Great company called them told them what happened during transit. The customer service rep was great to work with and sent me out new product with very little hassle.

oldstata

Sorry in advance for posting this twice,but a few of you helped me and I thought you would like to see the progress.
East wood tinning butter and lead work

Okay
1. Clean area very well if need be spot sand blast
2. Mix the tinning butter as it seams to settle.
3. Apply a thin coat of tinning butter to the area about 3" around
4. I used steal wool in vise grips and heated area as I spread running compond around. Apply a small amount of lead drops as your doing this to help prep the are. It will get really shiny when ready

5. Apply lead where needed and begging to work with lead paddles
6. File to finish up after area has cooled
7 clean area very well before paint
