A long file would work, maybe even a dowel with sand paper on it. Banged it on the garage step ;)

I have built a round copper manifold and I am now wondering how to remove the burrs inside the curved pipe.

What did you do to get the burrs out (other than banging it on the garage floor :-) )

Thanks,

Once I bumped it off but I was able to reach in a reset the pipe. 150F is pretty warm though for bare skin. Hoses are generally NOT food safe. Think of what water tastes like coming out of a garden hose that has been sitting in the sun. Rubber comes to mind. You could probably get away with a stainless steel set screw if you are really worried about it. As for cleaning copper, detergent is what I use (PBW or just soap and water). Stay away from bleach solutions.

I was planning on connecting the manifold to the pipe nipple with a short length of flexible hose. Any reason that this wouldn't work? Could the hose have problems sitting in 150 degree water? I thought I could use two hose clamps - one on the manifold and one on the pipe nipple - then no worries.

There is a little elbow on the manifold that slides inside that, thus making the connection. Nothing is welded together so it can be taken apart for cleaning, but be careful not to bump it when stirring.

It works for 5 gallon batches. I get a 3-4" grain bed for 9lb of grain. In terms of efficiency, at first I got 60% but now I'm getting ~70% which is low but it doesn't bother me. Adjusting the grind, getting a good digital thermometer, and tailoring the water chemistry with brewing salts have helped. One thing that is not great about this design is the amount of dead space - that plays into efficiency because of the loss of sugars.
