This is a seperate build from the other, just wanted to clear that up. It will be 16 inch diameter, 32 long cooking chamber with 16 inch firebox, simular to the others and Im using the same firebox design as the others.
Difference is , this one will primarily be a propane grill. I was thinking going with a 28 x 3/4 inch pipe burner and high ( about 15psi ) regulator would allow for a single burner to crank it up pretty darn well, and I was going to plumb it in from the opposite end of the firebox. so as regulalor and ignition could all be n that end, and keep the bottle away from the firebox. I'd like to stay away from a lot of removable parts, just becouse I dont want it to complicated. But I want it to be able to fire up the propane grill regardless if the firebox is going or not. and that also limits using attachments.
I am on the same though as theChuck in as far as designing it to deflect the grease away from the burner, using v plates and such, an easy fix would be to "pipe" the heat under the cooking chamber to the other end , basically using the bottom of the cooking chamber as the reverse flow plate, by welding a piece of chanel to the bottom, but I just dont think it would be very attractive.
I'm going to have to get my head around how to design the v plates and where to deflect the grease to, its just I dont have much experience making gas grills, I always bought those. And they look like they keep a lot of distance between the burner and the cooking grate.
