I've been working on this for a couple months.. finally got it to the point where I felt comfortable doing a "cold" smoke on some Salmon. Turned out Very Good!!! Albeit; I had to finish it off in the oven in the house. Turns out that the lone, small electric hotplate just don't cut the mustard. Couldn't get it above 120 Degrees F no matter how hard I tried. My triangular Smoke Generator seems to work pretty good... but I'm thinking about making a cylindrical version with the venturi tube @ the top instead of the bottom... more on that later. I'll try after this text to post some photos... and I have a link to a "First Test of the Smoke Generator".. let me know if it works??? TIA I started out just wanting to make a cool smoker box...and ended up making what I think is a very cool "Smoke House On Wheels". I really need to have almost everything on wheels 'cause my wife likes most things to be "Out of sight", so they appear to be... "Out of Mind". Me.. I like to have everything all around to view and marvel at all the time... Go Figure... women are just different that us men. ;-) Most of the differences I like... the rest I make allowance for and try to do my best to keep peace in the household. ;-D Now.. lets see if I can post some of those photos of the build .. some in progress... etc. BTW: IT's still a work in progress; as I do intend to add a better heat source for proper smoking of items that require more heat. I have been thinking about using a propane burner from a "Turkey Fryer".. or maybe an electric element from an old stove, complete with the thermocouple and control circuit of course. I have recently added a cool "Oven Light" and associated electrical system with an external weather proof switch... more on that to come as well... especially if I decide to add the electric Oven stuff. (BTW: Yes, I am a qualified electrician) FYI: I started out with a 1/2" plywood understructure I.D. 20.5" x 25" x 48" and then added the 2x4 frame and roof and then ... thought .. Hey.. how about a Metal roof... and how about some cedar siding.. and how about a really cool copper chimney.. and then an adjustable "Flu-damper" and on and on it goes... where it stops.. well.. we shall see. ;D I'm trying to upload a video of the "Burn-In" first smoke... link coming soon.
