New stack questions

[maple flats]

I just picked up my redesigned stack today. The shop cut the top of the Leader SS stack so it is square and even, and sized slightly larger than the 12" top stack. Then he made an adapter to insert into the top of the base and then to accept the 12" top stack. It looks great. I furnished the 20 ga bright annealed to use, he made the adapter and re-cut the base to fit it squarely. He charged $60, money well spent. Now I've go to hook it up and get things ready. I also need to buy more jugs because I need to re-pack another 40 gal BBL of DA into retail. My light and medium are still good, but my dark sells way faster.

Can't but wonder if you are over thinking it.

Maybe, but I hate seeing stains streaking down the outside of a stack, SS or galv. It just looks bad!

I put the new base stack and adapter up on the arch today. It looks nice. Now I need to decide what I'm going to do before I finish.
My last stack (galv.) had 2 extra layers, each spaced out 2" from the previous to protect the wood. This time I'm still trying to decide if I want to do it that way (in SS) or if I want to install the rest of the stack up thru the roof and protect the wood with either 2 layers of flat SS spaced out 1" on non combustible spacers, or use some ceramic insulation. The 2 SS options would likely look neater but all 3 methods will do the job.
