For  your  next   practice,  try
working  with  different  thick-
nesses of  steel.  Working  with
pieces both thicker and thinner,
you will notice that you have to
change your techniques somewhat.
Experiment   with  torch  angle,
flame size and speed of movement
from  right  to  left.  How thin
gauge steel can you weld? See if
you can  weld  1/4"  thick steel
without difficulty.~

    If you need to weld anything
thicker than 1/4" extra precaut-
ions  will  be   necessary.  The
sparks  and  slag will be bigger
and  travel  farther.  The  heat
generated will be more dangerous

Try  mitering  and  welding  two
pieces of round tubing.  You can
use  old  American-made  bicycle
frame tubing again.
    Miter  one  of  the tubes to
fit  against  the  other  with a
large  rat-tail file. Try to get
a fit  accurate  within 1/8" all
the way around. Weld them toget-
her as indicated, let them cool,
then smash  them  apart  with a
hammer.
