Hi Chamelion (ain't heard from you in a while)...

Hi All 

Remember, this gadget / trick? (converting a Cobb to gas)?

Well I wanted to wait until I got a second Cobb as a back-up just in-case I bugger things up, and two Saturday's ago JACKPOT! found a whole Cobb for R200.00 smackaroos..Cool

Ok, so I had to push this to the bottom of the "koppie-raas" list, but finally, I get's to punch the hole through the bottom today.

Now, all being well in the land of "koppie-raas", sometime this afternoon I might just have a Cobb for R200 bucks.. 

The centre coal grid is missing but it has the roasting grill & a bag, the grid can be bought seperately.....

Any taker's ???

Slightly quicker downhill....
These days a teeny-tiny bit more slightly quicker....

Ok so I wasn't happy with the stabilty of the bowl on the cooker plate,...Surprised ....So I modified the cooker plate (a Cadac budget stove) by folding the vanes back down (the vanes are punched & bent vertically) as well, and the inside base of the Cobb bowl now sits flush with the underside of the burner....Cool...

Fired that up.... Works a bleedin treat

Then I wasn't too happy with how much air-flow there was between the stove-plate and the bottom of the Cobb, so 1 x hammer and a copper drift sorted that out.

Then I found a piece of 1mm plate big enough to cut a cover plate for the inside, so that I can revert back to organic fuel, and marked it out....

Now moet ek hom mooi-mooi uitsny

Tootlelooo off to maintenence...

Ok so inner disc cut from the 1mm plate, now my cobb will work lekker on either organic fuel or LP.

For anyone wanting to do the conversion, I will post photos on Moaning-day

Essentially, the hole through the bottom of the Cobb bowl is 67 - 70mm The material is Stainless steel and difficult to cut through.

I used a circle cutter on a bridgeport milling machine, with the bowl clamped upsidedown to the table.  (1/2H)

I'm reasonably shure it can be done with an electric hand drill, but use a 2 - 3mm bit and soapy water to cool. Drill around the inside of the outer edge remove middle bit and finnish with a grinding stone of about 20 - 30mm in an electric drill.

The inside cover plate so that I can still use the Cobb with organic fuel and the original plastic outer shroud (cool to touch) is 135mm Diameter. (1/2H)

I used 1mm thick mild steel plate, Hacked it more or less round with a hacksaw by clamping the metal, then cutting along the top of the vice (using the top of the vice jaws to cut against), then grinding the whole thing nice and round.

The gas stove plate I used was the Cadac "Budget" stove, I'll show pictures of the modification to the vanes, best I can describe this is I bent them closed then from the bottom cupped them to roughly the shape of the bottom of the Cobb. (1/4H).

This stove top I will dedicate to the Cobb, I've got other's

I'm gonna save this mod in Word in my "camping" folder in case anybody want's it I can mail

So. That' another gadget done... Thank you Chamelion for putting me onto this mod
