Nick, morning.... The thicker the RF plate, the more thermal mass it has.... Heat retention, uniform heat distribution, less chance of warping.... Not only is bigger better, thicker is better too.....This is an incredible build! I've been on here only a few weeks and just stumbled on to your thread. That is true craftsmanship! Dave, I also have a question for you. I believe it was back in August that you made mention of Kaiser really appreciating the 3/16" RF plate. Why is that? Better all around heating? I was originally going to put 1/8" in mine, but now you have me wondering.
nick...... If your location was listed in your profile, I would know where to drive, bearing gifts, to help you dig through the scrap pile....I appreciate it Dave. I'm lucky enough to have a brother in the metals fabrication industry that will supply me with whatever I want out of his scrap. I talked to him yesterday and he's sitting on about 5 tons, and a bunch of it is 1/4"......guess I'm going thick now! Thanks for the knowledge.
