Questions are best asked in the forum. The posts will last longer, and will be seen the most by members. After a few more posts in the Shoutbox, the post you made will no longer be seen.... maybe you could also introduce yourself and share a little.

I'm looking to hire someone to teach/help me to find the best roast profile for the 3 types of coffee that grow on my farm in nicaragua. I live in LA, but but could go anywhere in so cal with my Behmor for a roasting lesson. Please contact me if you're in

When your wife thinks 30 grams for a 6 cup setting is strong, you learn to drink muddy water when you are making coffee for both of you.

I use a rule of thumb of 60 grams per liter. 8 cups (1 liter, 32 oz) = 60 grams, 6 cups (3/4 liter, 24 oz) = 45 grams. 10 cups = 75 grams 12 cups = 90 grams

OldMan41, depends what is "a pot"... usually is more accurate to specify the brew ratio, instead grams of coffee. The most usual is 1:15, thus 40 grams for 600 ml of water. If the 100 grams are for one liter pot, then we are talking about 1:10 ratio.

Bake a round duo dimensions
Gullygossner
These units seem hard to come by in Canada. I was wondering if someone could share the dimensions (od, height and thickness) of a bake a round duo unit.
renatoa
From Amazon listed items description seems like 14 inches x 3 1/2 inches in diameter, no clue about wall thickness, I guess 5 mm.

Check tri-clamp tubes on Aliexpress, there are builds here based on such hardware.
You can also consider Coleman lantern glassware, the M size is 88mm OD 80 mm ID, closest to BaR.

Hang tight, Gully - I'll head out to the shop later with some calipers and get you exact dimensions.

Interesting that you included "Duo" in the name. I've not come across that before, although I see eBay listings with the "Duo" name included, and they all look like the standard old BaR. But "duo" refers to a pair of something, so ... what am I missing I wonder? Does "duo" refer to the tube and its holder as a pair?

Some came as a 'Pair'. I have one, a rack to carry both came with it.

Yes the "duo" came in a two pack and was shorter and slightly smaller od. I think the standard bake a round had an od of 3.5" and a height of 14" but information on the duo is harder to come by.

I am wanting an extension for a poppery I roaster and the duo fits the unit perfectly and is proven by past members to work. I can measure the id of the poppery I but I'm not sure what thickness of glass to go after.
Scorchy
Ah, interesting! OK, I can still measure the glass thickness on the non-duo version if you'd like.

Can't hurt, gives me a reference.

I have a contact who can do borosilicate glass so thinking I may see what he can make.

I'm getting around 2.30mm.

What do you mean extension for a popper? Glass on top of original tin roast chamber ?
Stacked or telescopic fitting?
Do you have handy an example how this was been already done ?

Thank you !

Post #2 of the thread linked below shows what I am trying to achieve.

Got it, thank you !
Not apply to poppers models available here... and too much tinkering, imo.

Just for post completeness I would like to add that I was able to find a suitable chimney through a glassware maker at a local university.

The nominal dimensions of the tube are 75mm x 2.3mm thick, cost me $40 and works a treat!
