Sure, you can drill it right to 3/8" if you want but that doesn't make for a very sturdy solder joint.
Whoa careful tell anyone to listen to Joey Chopps I don't want to get a huge ego! Haha

Coppertubingsales also has the reducers, in case you are also ordering your tubing from them... just sayin.

I have quite a bit of 1/2" soft copper at my disposal... any chance of using this instead of the 3/8"?

Hell yeah, that would be even better. I'd suggest a larger diameter hose though.

I was thinking that too but I don't know if the rubber hose is as readily available in sizes greater than 5/8" and I'm not sure if the 1/2" copper will fit if it's not.

Finished my CFC two nights ago, other than the hose clamps. Can't wait to give it a whirl. Cost me about $52 to build it.

That looks great! Good thought with the elbow bends... I may end up adding those.

Thanks Bobby. I built mine a few weeks ago but have been too busy to brew, I hope to brew this weekend. I just had a question about cleaning out the system. I have this new CFC, a new pump and new cam locks/hoses. What should I use to make sure the whole system is clean and ready to brew. It is plumbed to recirculate to the brew kettle so I could make a solution and let it circulate for a while. Any help would be appreciated.

I just went back and read a few of the early posts that suggest to run a mixture of white vinegar and water to clean out a new system. Is this good enough? It's cheap and easy, so I like it.

Ok I made one of these this past weekend, but I mistakenly bought 3/8 copper tubing (1/2" OD), I even managed to get it into the 5/8" rubber hose. and all soldered up. Since I went with a larger tube than the OP designed, it would have to cut down the amount of chilled water flowing through the hose. Will it still work, should I start over with the correct size tubing? I'm worried there may not be enough water to cool the wort and overheating the rubber hose (melting). Although, the increased flow of the wort with the larger tube may yield better cooling..... I'm giving myself a headache, anyone else done it this way? Did it work?
