After finishing riveting the brackets..Note: I have decided to position my air compressor in KL permanently coz the majority of riveting in the future involves big parts like the flaps and wings stationed in KL plus to be more neighbourhood friendly back in Singapore. Only minor cutting and drilling w/ less noise will be done in Singapore during weekdays only from 10 am to 5pm excluding all holidays , not that there is any complaints but just my guilt for making a bit of noise so far for almost a year.
