Hi, looking to build a manifold for mash tun. Any suggestions on what size to drill holes into the copper pipe and length. I currently have some .5 inch on hand. I am using a 25 gal pot. Thanks

Palmer's howtobrew.com discusses manifold building in more detail than you can stand. Appendix D.

I am just finishing up building up a copper manifold, I did use Palmer's book as a reference. I went with 1/2" tubing and fittings and used a hack saw to cut the slots. I have a friend with a similar set up and it works great for continuous sparging or batch. Hope to try mine next weekend.

Why not use stainless braid? It is much easier to build and maintain...

I used a small cutting wheel on my Dremel and it worked great

I tried with a hacksaw (24T) and it was hard..switched to 32T and it was a bit easier - but I still wan't satisfied with the product.
I then borrowed a cheap version of a dremmel with the cut off wheels - it turned into a masterpiece of engineering for someone who was somewhat loaded at the time.

Cheers.

yeah with the Dremel it was fast and it was like cutting warm butter with a hot knife . . . only thing is the copper pipe did get war at times so i needed to have a brew waiting for it to cool off . . . not complaining just saying I was "well off" by the time I finished

I have been using a false bottom on my 10 gal rig with great efficiency. Now going to a 25 gal rig and looking for the best solution for my tun. What kind of efficiency are people getting with the manifold? Thanks for the earlier replies.

In Germany, is a stainless braid 'manifold' called "Lauter Hosen" ?

Anyways, I just brewed my first batch with a strainless braid. Simple mater to cold chisel the ends off- I couldn't find my tin snips. Plastic liner slid right out. Copper electric wire to crimp the far end, and hose clamp a piece of copper tube and a small rubber stopper made it fit my bottling bucket spigot internally. I used about a foot of copper tube with the far end bent 90 degrees, so it can't come loose while sparging. To install, slip the stopper up the tube a ways, slide the end into the spigot, lower the far end with the lauterhosen - the far end will butt against the far far side of the bucket, then slide the stopper down the tubing into the spigot. So I still have a virgin ice chest / mash tun.

I also just used a hacksaw to cut slits into mine. I just cut almost half way through every 3/8 of an inch. That's about every cm for you metric freaks .
