Being an apprentice boilermaker I can get most of the material and tools from work which is why it is so cheep for me.hope you guys enjoy the pics as its been fun for me to make this and have learnt a lot about plenums and my trade doing this Link to comment Share on other sites More sharing options...

Well done. Link to comment Share on other sites More sharing options...

(im only assuming you are going to weld it by the pics) Link to comment Share on other sites More sharing options...

Is it worth doing? Link to comment Share on other sites More sharing options...
