Discovered this week after hamfistedly destroying the rear dropouts on my treasured 36 year old Panasonic Bicycle.
With deep remorse I determined to replace them, the rear hub, and the rim.
FatFree bike shop supplied a new 36 hole rim, and I already had a new rear hub, so I laced that up, and set about finding new dropouts... Bingo...

"Bird" at Fatfree said there were no bicycle frame builders in Chiang Rai, but suggested asking car-radiator repair shops to braze the dropouts on.
I asked several metal-work shops, but they all frowned at the impossibility of them performing brass-rod brazing.
Until... I found this fabrication shop on the main highway 10km north of Maechan in Baan Maekham.
It's next to a large agricultural supplies shop.
The owner "Lorng" said he'd never brazed a bicycle frame, but did lots of brass-brazing on cars and tractors etc, so we watched these YT videos of removing and replacing bicycle dropouts, and he said he'd have a go.
Here's an Aussie chap removing a front dropout, the action starts at 2:13
Brazing a dropout:
Here's some snaps I took of "Lorng" at work on my frame, which is now ready for repainting.
We aligned the dropouts by eye, and with judicious cold-set bending, soon got the new rear wheel aligned good as new.
He charged me pennies, and I heartily recommend "Lorng" to you for any; metal work, oxyacetylene cutting, fabrication, welding, soldering, or brazing.
He's a young chap, works alone, and needs your projects to keep afloat in these testing economic times.
Support your local artisans, or be at the mercy of the big-box-store-throw-away mentality.
I'm drawing him a worksheet to make a new chimney for my stainless-steel/brick bread-oven. Then I'm going to ask him to cut and drill some one inch square metal tubing to make a sala-frame held together with bolts and wing-nuts, so I can move and store it easily.
