Spicewine has one for their Spiceboxes.
Had one fabbed up for my Lang just to allow for overnight powernaps between fuel reloads... (3 hours).
Don't know any offsets that will do that off a single load... except for a pellet driven Jambo.
how big was your basket for the lang? I wanna make one for my 20x48 offset so i can use it during overnight cooks as well. or at least if i put it on at 2am i can hopefully sleep till 5 then again till 8.
Nothing real scientific...
Emptied out the firebox... leaving just a fire grate in the box... and measured how big the opening was from the grate to the top of the opening.
Measured how wide and deep (left to right) and from the opening to the back to the smoke outlet... and subtracted 2" from all sides to allow space. Had the grate remade as well... solid steel frame, legs out of angle iron, and a double layer of expanded steel with one level slightly offset to retain burning pieces... only finer ash particles to drop.
Based on my offset... the charcoal box is on the bigger side... will hold over 30 lbs charcoal easy.
Thanks. I'm prolly gonna make one soon for mine.
This thing held it up to temp for 3 hrs? Did u burn sticks first to get it up to temp or starting cold the coal got it to temp? And if u fill the basket how much lit coal did u put on top roughly?
That is a slight risk.
Don't have the smoker here for pictures... but will try to explain.
note: I actually use my boot to kick the basket up/down to knock off the ash before pulling it out (partially). Already under the firebox is a automotive drip pan (2' x 3')... with a jackstand in front of the open firebox. Adjust the height of the jackstand approx. the same height as the fire grate. Using welding gloves, pull out the firebox partway and rest it on the jackstand.
I've pushed the live coals towards the smoke chamber and poured in a full bag... but it does cause some live embers to be dropped. if I don't... just poured the bag over the lit coals will create some unsightly white smoke... but it is short lived and no bitter aftertaste... will burn upwards without a problem.
I typically grab the box and pick one end up and drop it a few times to knock off the cling ash. I then use my ash removal tool (old golf club, head removed, flattened and bent into an L shape) to scoop out the ash under the fire basket. I then take my coal shovel or tongs and move all the hot coal toward the blower door. I then load new coal closer to the cook box. Fire moves toward the cook box as it burns down.
I have to clean ash at least once during a typical comp cook.
