Gas Cutting

Today in the fab shop i had to cut out a large

disk for my utensil project so obviously

i had to learn how to gas cut a circle instead

of getting it done for me.

The first process to be done was working out

the center point, i was looking for a diameter of 

140mm on the circle. Using a scribe i got

markings onto it and center popped it and we 

ready to go.

 

A little demostration of getting the right 

size of flame from my coach for this little

project, captain sellers.

 

 We were using a tool i showed eariler that 

helps cut a perfect circle with the torch, the first

part you have to do is cut a little section unguided to the 

start of the circle, then you place the tool into the 

center pop and start guiding it round cutting.

The key to cutting is to keep it flowing quickly and to keep

the torch tilted back so that the nib

isnt touching the metal. The quicker you are

the cleaner the cut will be along the side.

It was a little difficult i will admit but i

got the hang of it near the end and this was the result

a almost perfect circle.
