Mr. G. Brettin's Slow Motion Leg Hump

gbrettin · 01-11-2021, 03:28 PM

I attempted to drill 3" holes in my pipe and learned two things.

1. use a new sharp hole saw.
2. have a lot of weld, if not all welded where the hole will be drilled.

The first hole was semi decent. The second hole.... Well, that grabbed and ripped the pipe in half. Some of the pies got bent (in areas that didn't matter much). I pretty much rage quit when that happened and came back on my Birthday (Sunday) to work on the intake pipe a bit more.

I tried using a new hole saw and then bent the tube a bit more so I ditched that. I then opted for Mr. Death Wheel. Chunks were cut out pretty close to where I needed. An air grinder was used to clean up all the edges.

The intake is ready for final tacks and then full welds. The tube is not perfectly symmetrical but that's something I can live with due to the level of efforts to go back and rework a few spots.
