Richie , you'd can't weld linings in drums!!!!! If it ever failed and an investigation was carried out they would hang you out to dry - not good news for a builder who needs his licence !

Shaun, no no mate it is as per my description... It would not be cheap though... Rich has the right idea, skim the drums then pending on how much is taken off consider over sized shoes... It's not the end of the world kids, "It'll Fix" just after the show when my bank balance has recovered :-)
For gods sake mind Kev don't bin any of your drums until I have done a bit digging into this...

If you take the drum to a brake place they can have it machined and fit new oversize linings to the shoes which they can then radius grind to fit the new drum dia.

Why was one shoe worn?
With the expander assembly free to float, the shoes should have self centered.

One adjuster had stuck so one shoe was contacting more than the other

Does anyone have a datum ref regarding the ID of the drum when new ? And the thickness of the shoes when new ?

Brake lining dimensions are given at the back of the Brake section in UC-F1 as 3/8 thick, 2-3/4 wide, 12-1/4 long.
I have had sets bonded before. If you have your drum turned by a known diameter, you can have an equal thickness of shim installed under the lining to get the proper arc, but in that case you will also have to rivet as opposed to bonding the linings to the shoe. Personally, I have always turned the drums clean, had the shoes relined, then had the shoes ground so they fit into the arc of the drum. They will still need to set themselves in to some degree, so don't expect perfect brakes right off, and expect to have to re-adjust them a time or two as they fully set in. The braking/turning power of a clean set of drums and shoes will not be experienced with grooved drums. Surface area is the key.

Rich. theres no spec in my book so try this. I think the original lining thickness was 3/8" So take the curve of a shoe with no lining. Plot a circle from it, adding 2 x the lining thickness, which should give you a nominal size Something like 15" From this and the unworn lip inside your drum, you should be able to make an educated guess at the original drum dia, and how much might already have been turned from your drums. Probably Richard F. is on the nail when he said it might be original dia. plus wear.
