I did some more de-burring on the pans because if it's all bare metal, it will be a lot easier to weld, and I'm not that good at welding and I need all the help I can get.
I got the front and back both. By getting it to bare metal, I won't have to smell the coating burning but I do weld with a respirator on. I guess I mentioned before that I use supplied air all the time, whenever there's a chance of any airborne dust or fumes.
This air rachet makes things go pretty fast, I must be getting old, no! I AM old... I think I mentioned this before.
In the tunnel area, I'm going to drill a couple of small holes right next to the support, then I can mark it on top for my cut. The air cut-off saw will be at an angle from underneath.
You have probably heard some talk on here about the thickness of hack saw blades and cut-off wheels, so I checked a 3M 1/32 thick wheel. It's actually .055 which is quite a bit bigger than 1/32 which is .0315, then if add the play in the wheel and the burning you will have 1/16" thick cut with a cut-off wheel. I also measured a hacksaw blade for an air operated saw. The one I have is Snap-on and is actually 1/32. I'll show a picture later of the hacksaw.
