not square

[andyuk697]

hey all

after a bit of pratice welding i finaly got the courage to spot weld the first 4 pieces today, they are all cut perfectly to the mm and just cannot get all 4 corners to perfect 90 degrees square i have used welders magnet a digital angle setter and a solid steel 300x600 square to check them.
what am i doing wrong?

are you talking about the 4 main lengths in the base of the frame?
if so have you put the little blocks on your build table to hold everything still whilst you weld?

Also check diagonals and straightness of the tubing and obviously each pair of opposites should be exactly the same lenghth when held up against each other

hi
thanks for the replys yeah its the first 4 pieces on the bottom rear part they are perfect lenth and each pair is identical lenth as theyre only tackt i can adjust slightly with my rubber mallet but everytime i adjust one angle it moves the other
also each angle diagonally across is the same somthings obviously out but i cant figure out what
if my hair was long enuff id be pulling it out lol

cheers Andy

suggest taking the tack welds off, then clamp each piece to the build table, check for true square before putting any more tack welds on,
maybe the table is not "true"??
