    Reverse Flow 300L Air Tank Build in Greece...$20 Stick Welder and Angle Grinder

    Alright, we made some progress, but it was slow and difficult.  A lot of mud after the rain.  Got a couple of jolts from the welder, as there was some water sitting under the air tank.  I was touching the metal and putting a welding rod in the rod holder.....zzzzzztttt!  That'll wake you up!  ...

    Reverse Flow 300L Air Tank Build in Greece...$20 Stick Welder and Angle Grinder

    Usually you can get it at any hardware store that has steel, Home Depot or Lowes.  You can even find it at the scrapyard like I do sometimes.  It's the cheapest way to make door seals that I've come across and it bends to shape fairly easy.  Also, it doesn't spring load when you bend it to the...

    Agreed.  It will take quite a bit of material.

    Reverse Flow 300L Air Tank Build in Greece...$20 Stick Welder and Angle Grinder

    These discs are approximately 1/16 or so, less than an 1/8 for sure.  I think the last ones I bought were from Makita.  The plasma will probably take away significant amount of metal also.  Maybe if you find a laser cutter or waterjet, you can reduce that loss and gain some tolerance.   Most of...

    Reverse Flow 300L Air Tank Build in Greece...$20 Stick Welder and Angle Grinder

    Yep.  Just cut out the end plate from approx 1/4" steel.  Surprising thing is, the steel from the tank is thinner, but seems to be much higher quality than the new steel I bought for the end caps.  It was sure a lot more difficult to cut.  It seems to weld better too.   It's a bit of work and I...

    Reverse Flow 300L Air Tank Build in Greece...$20 Stick Welder and Angle Grinder

    I actually trimmed it another inch today to raise the firebox and welded on the end plate for the main chamber.  It's raining a lot this week, so I'm a bit slow to get stuff done.  Worked on the firebox door a bit.   The calculation from Feldon's is for a half moon.  I actually have an...

    Recalculated for area instead of volume and came up with 62.31.  According to Feldon's calculator, I need 62.85 so I'm going to widen it just a bit to gain a little area and then weld it up.

    Reverse Flow 300L Air Tank Build in Greece...$20 Stick Welder and Angle Grinder

    Yeah, it's a lowrider!!!  Haha.  No, seriously I just propped it up on scrap steel and a lawn chair to check my cutting.  Wanted to make sure the main chamber and firebox would mate up properly so I can get a good weld on it.  It has quite a bit of clearance in there.  Not sure what gap to keep...

    Reverse Flow 300L Air Tank Build in Greece...$20 Stick Welder and Angle Grinder

    I took the ends of the tank and welded them back together to for a firebox.  I had planned to build a square firebox, but after seeing how thick this steel for the tank is, I decided to use it.  Planning to cut out the top and add a flat top in order to attach a warmer/rib box.   Door frame...

    Reverse Flow 300L Air Tank Build in Greece...$20 Stick Welder and Angle Grinder

    This old tank had a massive amount of rust inside it from years of neglect and probably from not draining it properly.  Those old compressors built up a lot of moisture and typically cause rust when the tanks weren't drained and taken care of properly.   Decided to tilt it up on the side and...
