I spent the weekend making burners. Primarily to remake the burner I had done for my 3"vertical boiler http://www.homemodelenginemachinist.com/index.php?topic=8687.0)](http://www.homemodelenginemachinist.com/index.php?topic=8687.0)[/url] now I have soem tubeing of the right size, but as I was making parts I thought I'd have a go at a poker burner having seen a picture of one Ora Banda had done.
Somebody had suggested making burners out of stainless rather than copper so I thought I'd give it a go. It turns out to be way cheaper than copper, so stainless it is from now on.
Cutting the burner barrels on the mechanical hacksaw. (very usefull tool and way easier than cutting by hand)
Tubes turned to size and base plates rough cut
Barrels and base plates silver soldered and bases turned down to the barrel diameter
Squaring off the end of the poker burner tube
Three jet holders ready to be silver soldered into the burners
Poker burner on first firing. This is very encouraging as it worked 'out of the box'
I had intended to drill three rows of 1mm holes down the length of the tube but had left drilling these until after I'd done the soldering, so I could get everything lined up nicely. However, the tube had hardend and after the first of the 39 holes I gave up. 13 cross cuts in the mechanical hacksaw and I was cooking on gas. It looks like the horizontal boiler I have been considering doing is feasible. I'm going to base it on SandyC 3" vertical I've just made (see link above) but offset the center tube, not include the cross tubes and add some end to end stays. The space end where the burner sits on the vertical will become the smoke box. I just need to redo the calcs to see if the flue, without the cross tubes, is still within safety limits.
