I read somewhere that higher elevations have faster roast time and require somewhat lower temperatures. air is thin and has less Oxygen

Yes, 1st off, you must use only Panama Esmeralda Geisha beans and be sure to only roast on Saturdays. Actually, this isn't completely true. Please post in all about roasters forum. Thx!

I’m at 9,000 feet elevation, is there any special adjustments that need to be made to roast using an SR 540 at this elevation?

Bake A Round Alternatives
Gullygossner
The pyrex bake a round appears to be a go to roasting chamber on many builds. They are very tough to come by in my part of the world. Are there easily accessible (ie Amazon) alternatives to the bake a round?

I've used borosilicate tubes sold as replacements for old gas lanterns. Found in outdoor/camping stores.

Or just cut the base off a glass vase? That's what I'm currently using in my large air roaster. Yes, I like doing things on the cheap.

I've tried cutting glass in the past by scoring, heating and then submerging in cold water. This has not yielded favorable results. Are you using a dremel or another method to cut the bottoms off your item of choice?

I scored the glass with a glass roller scoring tool thing, then alternated between hot and cold water poured onto the score line until it separates.

Such discs:

... in a proxxon (dremel like) drill/grinder tool.
Cut under a water jet, to avoid any glass dust. Safety glasses, dust mask...

Here is a supplier I found, they will make pretty much anything for you at any length. Their prices aren’t outrageous either.

Unfortunately, no size in their offering is optimal for a roast chamber...
All I found is 2 ¼" OD, which is too small, and 5" OD, that could be too big, and too short given the maximum 7" long offering...
This is what I found in this section:

... maybe elsewhere you was more lucky...

If you call or email them they have a lot more sizes.

Maybe worth a look? These are the glass tubes used on patio heaters, can be found in several sizes and prices on amazon.
