Took the bicycle in this morning ... very few house #s on Rakaeng ... from the moat continue through the offset intersection ... cross small bridge and its on your left hand side ... big white shed ... driveway down the middle ... welding on the left auto parts on the right. Very mcycle friendly environment.
Although quite busy, the young welder did the job while I waited. Paid 200 baht, and was even issued a receipt from the smiling young receptionist!
As the frame is polished aluminium (bit like a box section swingarm to look at) with the original meaty welds adjacent, the repair is almost invisible. 2 minutes to clean off the burnt lacquer with steel wool and no further cosmetic work required.
