I ordered 3 ea.- 1" thick 24"x48" Mineral Wool sheets from McMasterCarr yesterday for $6.82 each -- arrived at work today! Less than 24 hrs Wow - so this Weekend Ill be stuffing the Walls with this stuff.
Well got it insulated and pulled bottom front cover off and used this High Temp Metal pookie to fill a few air sucking gaps. I pulled top off thinking the hollow sides would be open but it is actually built a little better with top of outer wall folded over so I had to take the inside walls loose but they bend around the corners so they will overlap and are held with screws. They extend down past the difusser and firebox insert ( that is bolted in ) so I had to flex the front top corners out and stuff the insulation in. The side walls I did in 2 pieces each to make it easier but was able to use one large piece on the back. Also did the Top. I can tell a difference as the walls don't have a hollow sound anymore. After getting it back together I wiped it out with wet rags, sprayed it all with Cooking Spray again, filled basket 1/2 way with KBB and Hickory chunks and Dumped 1/4 of chimney of lit on top. Had both 1" ball valves full open till it hit 225* in about 25 minutes then cut them to half it started climbing temp faster and at 300* I closed them to 1/4 and it still climbed to 375* so I closed off both valves and it dropped to 340* so I cracked one valve just slightly and it's Cruising at 350*ish. The walls are Warm to Slightly Hot where they were Burn Ya Arse Hot with no a Insulation. I'm gonna let it run a cpl hrs and see how temp does and may throw on a Pork Loin. :wink:
It Definately would have Best to take it completely apart and insulate it from the start before the firebox and side plate Mods :doh:.. but Oh Well.......It Done :heh: Next up is a angle iron base with casters. :thumb:
Well Hell- came in, watched some of the Blowout at Cowboys Stadium, took a shower and go cack out to check on it - 500 Fricken Degrees- all charcoal red hot - air suckin pig! :evil:
It sucks Air which ignites whole basket which runs it up to 500* ......So if I add a couple dividers and make the basket one of them Maze baskets it can't all burn at once......Maybe-- - Well that's what I'll be trying this week.......and dropping the basket from 3 1/2" clearance underneath to 2 1/2". :mmph:
The original rubber gasket has burned up so I put 1/2" fiberglass rope gasket around firebox door and a firebrick divider in charcoal basket. Fixin to fire it up and let it runs a cpl hrs - if it holds steady decent temp I'll be trying a Turkey for a practice Run for Thursday. Using KBB and Cherry Wood n Hickory Wood Chunks- I dropped 10 lit Briquets into corner of charcoal basket.
