Would there be any advantage to an octagon made with 45 degree elbows, so it's more "round". Or would that just be more expensive due to the additional hardware?

That's exactly what I have, but mine is made with cpvc and fits differently than shown in this post. Works amazingly. If anyone wants more info, I can start a new thread.

I'd be interested in checking it out.

I brewed the other day and got a stuck sparge; after blowing into the silicon hose (and through the kettle screen) the end of the screen floated up to the top… this has been a headache from day one when trying to mix over 22lbs+ of crushed grain with a paddle and constantly hitting the screen. Anyway, after cleaning up the screen looked like this:

manifold1.jpg

Piece of *&$@!!!! But in darkness, as always, I turned to HBT for light and with the help from others I made this:

manifold2.jpg
manifold3.jpg
manifold4.jpg

I used a dremel tool to cut the slits (used two 1/32 cutting wheels sandwiched together) and was going to solder but after testing it the pieces are air tight.

It fits snug in my 10g round cooler and my dead space went from 0.4 gallons to 0.078 gallons (or 1 ¼ cup)!!! Awesome! Thanks HBT and HBT members!

Now, does anyone know how to remove the burs that are inside the ½ inch copper pipe???

Burrs on the inside of a copper pipe... Ah yes, here is how I got them out. I used a 12 or 20 gauge (pretty sure 20ga, but check your copper tubing size) shotgun cleaning brush (the stiff, prickly wire ones) on my drill, and ran it through the copper pieces before soldering, Worked like a charm, but ruins the cleaning brush.

Hope this helps!

That's a good idea! Would have saved me several hours using a rat tail file

I had some requests for the dimensions for my manifold… here they are. It’s a pretty tight fit in the cooler (10gal round Rubbermaid); you need to apply some pressure to get it to seat on the bottom. I like it like that, it hasn’t moved at all while stirring. It’s not tight enough to damage the cooler though… but +1/8” on one of the pieces might make it impossible to seat.

manifoldnumbered2.jpg

1. 1 7/8”
2. 3”
3. 1 7/8”
4. 8 ¼”
5. 3 13/16”
6. 3 13/16”
7. 8 ¼”
8. 3 13/16”
9. 1 1/8”
10. 1 1/8”
11. 3 1/8”
12. 3 13/16”
13. 1 7/8”
14. 3”
15. 1 7/8”

nibco-half-copper-adapter.jpg
(NIBCO 1/2 in. Copper Adapter)

Copper pipe: ½” X 5’ (I believe I got away with using just one 5’ piece… i.e., I didn’t make any mistakes).
Copper elbows: 4
Copper T’s: 7
Project fun: 10+

Note that this manifold uses over 4’ of copper therefore it might make sense to get two ½” x 5’ lengths of copper in case you make a mistake (save a trip back to HD). The high-temp silicon tubing is cut to fit. Attached to the inside bulkhead is a copper female hose fitting (NIBCO ½ in. Copper Adapter… see pic) along with a short piece of pipe so that the silicon tubing slips over it.

Also, a rat-tail file worked great to remove all the burs (I picked up the “Husky 10-piece File Set“ from HD for $10.97… a steal!)

Sweet. gonna make one next week. I made a false bottom on a water jet machine but I could not get the "dome" shape and it is horrible. After several attempts, I am giving up and going with this manifold. Sounds like I may have a winner!

That's exactly what I ended up doing with mine. It works great. I typically get around 85% - 90% efficiency. I drilled 1/8" holes in it rather than use a hacksaw or dremel.
