fork repair using lead
« on: July 12, 2008, 08:04 PM »
heres a few pics of some fork drop outs i repaired today using lead,before the days of plastic car body filler lead was used to repair dents fill seams and joints etc,i thought i would give it a go on some drop outs that had deep washer marks and it worked a treat  :)this sort of repair will only work if you are going to paint frame (not sure about powder)maybe dan would know???? lead is a much stronger repair and wont crack or shrink if it's applied properly,could also be used to fill dents etc ;)
before....

applied lead.....

sanded down ready for paint....

Nice job, I would have thought that it can be powdered as lead conducts electricity  :daumenhoch:

Be interesting to find out if it can be chromed, I think it can but not certain about it  :-\.

fraz you have to clean metal until its nice and shiney then tin the surface with solder paint using a blow torch, warm up lead and spread over repaired area which has been tinned using a wooden paddle lubricated with tallow(fat),it wont stick if it's not tinned first, once its applied just sand down using production paper 80-then 180 grit,its a lot more involved than plastic filler but will last ;)
you can get the lead etc from body shop suppliers,

looking good Phil (as usual) but couldn't you get the lead from old burner tubes?   ;)

it's good untill the first time you tighten a nut and the soft lead distortes again. better use a really big assed washer.

Nice job there. a word of warning about lead though. its very toxic and breathing the fumes is not recommended. if you dont know what your doing i would suggest not trying it . if the lead when melting/melted comes into contact with water it can explode.
 we use it in the blacksmith trade for securing raikings etc.

Nice clean job Phil.
But what's up when you fit wheels again?
Can they be bolted tightly or will dropouts go back to their original mis-shape ?
Lead is quite a soft material

i will fit a washer before nuts are tightened and its only on a show pony,the lead is usually used on car body work and is quite robust ;) it would also be good for filling large dents that wont pull out,
