Do you have links to the barb elbows, and the manifold, I already got the hose coming.

THNX, already had the gasket, in fact I already cut 2 layers for the lid... probably gonna just use a lead weight on then lid

I saw those Barb Elbows on amazon but didn't know you used brass... they don't look brass in the pics so I didn't buy them...

THNX for the links RemE, I'll work on mine now.

I used brass for proof of concept, then found stainless but it's pricey! I will add links tomorrow but they are around $16 each as I recall, not from Amazon. And they need separate barbs.

Checked Bella after 4 hours, still puffing away, working well, no condensation in the lid at all. Running pump at max, all 4 ports full open.

Looks great so far. Will probably add these improvements to my Bella. Is there a link for the stainless tube extension? Or was it custom built?

Well, I don't want brass hanging out so pricey it is...
You had to enlarge the bottom hole after adding the bottom insulation?
And why can't I PLUG one of the side hole instead of feeding both with air?
I would actually PLUG the hole I would use to put my flame thru with something easy...

Did you know those existing side holes would almost accept those 1/4 rivet plugs... I wonder if I should try one

Update, Bella still smoking! Mostly burned up inside, still very hot to the touch, no mess outside at all.
Brisket is now wrapped and heading to final phase.

I found it better to light both sides, it's easy to light and then screw in the fitting and attach hose. These 3/16 i.d. hoses slide onto and off of the barbs much easier.

Here's the link to the 1/4" NPT x 1/8" NPT Street Elbow (for sides) and 1/8" NPT x 1/8" NPT Street Elbow for top;

Regarding the bottom holes, not enlarged, but just tapered them slightly with a countersink so the side screws would guide into the holes easier when pressing the bottom in place with the 1/8" gasket material.

I love the smell of Hickory in the morning!

I used this tube stock, fits perfectly, I cut it at 16" length to get it past the fire pot;

BTW, very thick walled stuff! clamped in a vise and used a reciprocating saw with metal cutting blade and lots of oil to chop it off.

Will these work for the side holes??

Yup, same size as the elbows I used. I chose elbows to have the leverage needed to screw them in by hand but those will work.

When I lit the Bella, sometimes I had to open the side vent and hit it again with the torch. So the elbows came in handy. I used 50/50 pellets and "fine wood chips". This was more like saw dust which I don't think was very good burning stuff and hindered startup.

 

[Slimpicker]

I'll probably just have a deep socket set up so I can screw on and off... plus did you see they were only about $10 for 5 of those... I better jump on them before they change that price.

Well, since Smokin-it sent me a bag of custom mix I wonder if they sell it... where the heck am I gonna find wood chips

 

[RemE]

The Bella guy told me to get "Western" wood chips at local wallmart. I have some in the mail.

BTW, this clear silicone tubing also seems to handle the heat OK as well;

I like the idea of doing something like this to my Pro 780. But I wonder, does it need to be attached to the grill? Other than the hole for the smoke, and the tubes leading to it of course. But could I set it on something perhaps (like a ceramic tile)? I assume the outside of the "thing" gets pretty hot.

You could I suppose. but yes, it gets really hot! It's only 3" square on the base so it wouldn't be all that stable, plus getting the tube connection to the grill.
