Hi Everyone. I'm Mitch from Sydney Australia. I joined the forum to get advice on building my first small 84L (22gal) RF smoker. Planning on using an old Propane (known as LPG here) tank from a car for the CC, and another smaller size one for the FB. I have used the calculator at feldoncentral.com to do some initial specs.. - looks like my FB tank will be too small! - you can see my calcs here: http://feldoncentral.com/bbqcalcula...18,16.30&fi=0,0,3,3.07,0.43&fc=3.23,4.57,8.19 cheers, mitch.
