Since I decided to get a turkey fryer and do full boils I needed a wort chiller too, so being cheap I made one. Just your basic run of the mill chiller, I did use a ridgid riser tube and used stainless steel safety wire to lash the coils to the riser to make it a little less floppy. The other nice thing about using the rigid riser is I was also able to spread the coils out a bit more and it looks like it should have pretty good coverage. In all I burned about $45 from my bank account.
