Hi Had an hour free this morning so was able to get on with something I've been thinking about for a while. That is fitting this, into a trangia. Dead cheap from a chinese Ebayer. The result is this. The bracket was fashioned from some Ali I had lying about in the shed and the extended control was made from a stainless steel wall tie. The stove can be returned to normal without any tools and has the option of using two types of gas. Now I'm thinking why did I bother because I have the proper trangia gas burner anyway. Must be because i just like to tinker.
Trevor To be honest the hardest part of the whole thing was using an oil stone to reduce the thickness of the end of the wall tie., to fit into the hole in the control. Everything on the stove and stand came apart quite easily and the bracket was easy to make once I'd worked out the relative heights between burner and bottom of the pan. I might keep it like that as the trangia doesn't have a burner.
Is using aluminium for the burner head bracket OK (I thought I would need to use steel) and if so what thickness did you use?
Not going to speak for Gary, but my thoughts as follows. 1. Gary makes the Speedster backpacking stoves. He knows his stuff. If he used aluminum in that application, that's because it's fine. 2. Aluminum melts around 1200F. If you look at the burner riser, it's not heat discolored at all, and only glowing at the very tippy top of the burner at WOT. Steel and brass start glowing dully around ~900F, so we definitely know the burner riser and indeed most of the burner itself isn't anywhere close to that temperature. So, minimum 300 deg safety margin there. 3. Look at the original stove Gary harvested the burner from. The base it screws into originally may well be aluminum. It's fine. I'd use 0.0625"/~1.5mm stuff.
It occurred to me that stainless sink strainers* might be useful for homemade Trangia Gas adaptors (I'm assuming the burner head's input ports will be below the strainer: eg strainer rests on a stainless birdfeeder mesh cylinder). The 75mm overall diameter ones are a bit small I think, perhaps 80 or 85mm? *Sainsbury's online Grocery Shopping and Fresh Food Delivery
i've jusn notice Twoberths Bleuet Trangia conversion which uses a spring as the spacer (rather than mesh) a much better idea I think....
The style of strainer In the above post Trangia Gas Conversion didn't work for me so I just used some flat aluminium plate with two M3/M4 bolts 'self-tapped' bolts to located it in base, and the source stove's own pot supports (no suitable springs to use twoberth method) so Twoberths or redspeedsters ways are better...
I just used some of the 2in wide flat aluminium strip and two M3/4bolts to locate it,with the stove pan supports as spacer because I had no springs, but it works.
