Hey, thanks for the info and compliments!!
I got the handles off ebay, they are AGA cooker handles, but its someone selling them in the UK and they are dead stock. As im in the UK it really does suck for things like this, but i could find loads of places in America which make these sort of handles for BBQ's.
The doors are just 3mm sheet steel cut down. The frames were all cut for me as well and then a friend of a friend welded them together. The hinges were just from a local DIY shop (gate hinges). I then threaded the metal and screwed in all the bolts.
I wish i made the smoker door a little bit smaller but too late now.
The grills were off ebay too, a UK company selling "factory 2nd" grills (which meant they had welded some bits wonky) but it was the only grills i could find that were cheap enough for the grilling area (1000x700mm or there abouts). I did want some of that diamond mesh steel, which to my annoyance my old man told me after he could get, doh. So i have 3 smoker shelves cut out of it, these are stupidly big as well.. 600 x 750mm.
If you google brick smoker, your come across a instructables guide which i have pretty much copied. But used different blocks as im in a different country. Also i used bricks around it as they were cheaper than brick slips.
If you think sand and cement will take up to 500 degrees i think i'll risk it (whats the worst that can happen, haha) but also just put some steel or aluminum lining in to catch any flakey/dusty bits falling down. I'll be sticking a chimney on as well.
I think i came across Wes's build via youtube, bloody huge impressive build that. I did think about building the roof in a similar fashion but i dont i want to spend lots more cash on the bricks.
Hopefully i'll finish the smoker today and i'll have months of meating good times :)
I'll take a photo of the other bits once its finished. With the handles/latches we made something similar to a woodburner latch, but on the bottom door it is a double latch so the door can lock slightly open to let some air swoosh in to help with the fire or move the smoke about.
