I ran across this u-tube video of a tool to cut a straight line. Seems to work pretty good. The music in the video is awful, but you might get some ideas.

I'm a little surprised at such a nice quality of cut, with using angle iron on angle iron skids. Doesn't look like he did a real good job of sanding the mil scale off either. |

read the Utube comments,more complaints on the music than comments on the rig. Can a torch really make that smooth of a cut? Bill |

Takes three men and a drill to make a cut that I would have finished, before they even got their rig set up, with just a piece of angle iron as a straight edge guide.
Regards,

Here is a cut I made on 1-inch plate. When I built a log splitter for my brother-n-law. I didn't think about taking a picture until a few months after making the cut, so the plate set outside the shop in the rain. I didn't knock the slag off, or touch it in anyway, just through it off to the side away from the door.
Well I've been trying for 10-minutes to post a close up picture, but it won't do it. This is the most F__ked up site on the Internet for posting pictures!

Yes a O/A cut can provide cuts higher quality thasn that. The keys to successful Oxyfuel cutting are taking care of your equipment. The torch is NOT a hammer, neither is the tip. Keep the tip clean and properly size your tip to the material your working with and keep it clean. I consistently see folks over size the tip. The next step is correct working pressures, another mistake most folks make is to much pressure or the regulators are bottomed wide open. You local welding supply can fix you up with a chart that explains proper tip size and pressures if your not sure. A neutral flame is mandatory to produce quality cuts. Getting comfortable is one of the main things and the most important is safety. Use the correst #5 filter Lens and back off the regulators when shutting down. You can't do a good job if you can't see what your doing or have a reg screw blowed through yourself. |

I agree with you Charlie. A piece of angle and a hose clamp attached to the tip as a guide & all you have to do is slide the torch along. A lot quicker and easier from what I can see. Just my thoughts, Keith |

A magnetic cutting guide is nice accessory to have. I have a cast aluminum one that the tip glides on a lot nicer than a piece of steel. Lining up the preheat holes makes for the best straight line cuts and preheating thicker plate also helps. Off setting the preheat holes is best for bevel cuts. The cut in the video has a slightly rounded edge on one side most likely from too much preheat or having the flame too close. I sometimes use one size smaller tip and a little preheat to get a real nice cut with a thinner kerf. A perfect O/A cut will be cleaner than a sheared cut. On 1/4" and above. I much prefer a cutting torch over a plasma torch. |

What plasma do you have. Where I used to work we had
a Thermal Dynamics cut master 75. Did a nice job
when it was new. It got a little older and with new
consumables in the torch the finished job was less
than perfect. |

I stopped wearing laced boots only a couple years after getting into the welding trade. Got tired of replacing shoe laces. But the big reason I started wearing pull on boots was working over water. And I always wore a quick release rigging belt as well. That life jacket can only hold up so much weight!
