    Sorry I took so long to reply. I have been busy. I have been vacuum packing a 14 month old bull for the freezer. More fodder for the BBQ. Yes it took a lot of looking to find a bag big enough to fit him in. Looks like nice meat. We had some snags for tea. We don't usually eat them, but decided to try them and see whether we had to give them all away to the kids or keep some for us. They were nice. Bad luck kids. They'll probably snag () some T bones or rump instead.

    The only mesh I need is to cover the air holes in the BBQ body to keep the rodents out. Mine is homemade from a heavy wall 44. I fitted 4 cast iron burners which where the biggest cost by far. That was over 20yrs ago. I need to make a stainless steel grill section as the mild steel one keeps going rusty.

    Dean,
    I was chasing something on a forge burner the other day. In the write up the mesh was mentioned as a device for introducing turbulence of the incoming air to better mix with the gas.

    In the first picture I posted above you can make out a bolt with lock nut at the start of the wider section, which I believe is for the same purpose. It is screwed into the gas jet to break it up. Thanks for that info. It makes sense. The air will be drawn in as discrete streams.

    I paid retail price for the ones in my BBQ. Some time after that I saw some identical burners at a garage sale for I think $5.00 each. They are still in the shed.
