Looking to round off the edges of 3/4" steel on my tractor loader arms. Will an Oxy Acetylene torch be enough? What size nozzles do I need? Any other things I need to think about as a newbie? Thank you. Paul Pec

Welcome to the group Paul. I'm not totally understanding what you are needing to do. Are you talking about cutting 3/4" steel flat bar to make the end round? If so, just about any O/A torch will do that. Just be sure to never run the acetylene over 15 psi MAX. The oxygen isn't as limited. 40-50 psi will probably do anything you need. Please clarify what you intend to do and we'll jump in and help.

if you are talking about cutting you will need a 1 tip and the acetalene pressure should be 3-5psi and the oxygen pressure should be 30-35psi

Thanks

Gentlemen, Thanks for your prompt responses.

oxy acetylene

All right. Was able to cut what I needed, but not sure if I was doing it right. How far away should the torch tip be from the material being cut?

The tip of the inner cone of the flame shall be about 1/8" above the metal.

Take a look at the brief description of the procedure here: http://www.calaged.org/ResourceFiles...uster/2256.txt (chapters C and D may be of interest to you)

I am going to assume you are taliking about chamfering the edges of your loader arms. Not that hard for a beginner to do. Go easy on the oxy and grind off the slag,and i think you will be truly pleased with the results
