Well I'm doing it myself!

Had a quote for having a liner installed, $$$$. I had thought that since I am doing all of the boiler install, changing over from a coal stoker to a Weil-McClain CGa 4,I would save myself some effort and have the liner done. But after checking for material costs I can buy all the necessary components for about $$$. So am enlisting a few friends who have done there's to do the job.

And might take the savings and invest in a Tig welder that can handle aluminum!
