Some comments to accompany pictures. Tires are 10" airless from Northern Tool. I turned a piece of 7/8" rod down to 1/2" or 5/8" (can't remember which) at the ends to form an axle. Drilled through the 3/8" thick aluminum frame to insert axle and mounted plates on outside edges to prevent axle shifting.
Fabricated a front steering wheel so I have a tricycle arrangement to make easy sharp turns, This is also an air-free wheel from NT, I believe 8". Made a handle from some stainless tubing I had with a "T" handle, kind of like a toy wagon handle so it can be pulled and maneuvered. Wheel pivots on 2 pieces of 1/2" steel. No bearing between the flats, just some white grease. Axel is 3/4" turned down from my 7/8" bar stock.
Tank is not yet welded to the frame and won't be until I no longer need to manipulate it to enable easier welding. I'll likely roll it upside down to deal with the firebox and the cut out to the CC. I'm neither experienced nor flexible enough to be down low welding. Rear of the firebox will be bolted to the frame and welded to the CC.
Door is 48" wide and is edged with 1 3/4" wide 3/32" flat stock. Tank is 3/32" thick. End opening for firebox has been cut right at the weld seam. Will use the seam rise as the dam against possible back-flow of grease into the firebox. Not likely.
Hinges are home-made from 1/2" black pipe, the 1 3/4" flat stock and 9/16" rod. The 3" center section is welded to some 3" flat stock 3/32.
All the welds are TIG other than the very sloppy ones on the bottom and sides of the door edge where I demonstrated that I forgot everything I thought I knew about stick welding. Am having problems with my MIG machine and hope to solve them before it is time to weld the firebox late this week. Not looking forward to tigging that much weld....but will, if necessary. Will run a few pads with stick and MIG later this week to see if I can do a decent job with either/both.
Used a rosebud tip on my O/A today and a couple of pipe clamps to get the door curve back under control.
Am trying to decide whether to just cut the chimney pipe into the tank and carry it down to a 45 or 60 degree birds-mouth opening at cooking level or build the exterior stand-off and mount the 5" pipe on there.
Regarding my earlier post about possibly creating 5" circular vent openings at the bottom and one at the top of the firebox door, to get figh temps in the cooking area when desired, any thoughts from you Dave?
Hopefully will have my steel order Friday. Other than drilling and mounting a drain, have about run out of what can be done without more materials. I work Saturdays, so Sunday will be my next big day. Sorry for being so long winded.
Please comments/advice wanted.
