How to reliably set my bagpipes on fire

what about a .4mm 3d printer nozzle?

What about a system like this ? pilot on low all the time, electrical valve opens to produce the big whoosh !

or this of you want a separate pilot

That’s what I suggested, but with a fancy diagram!

Sorry, i’m a consultant, I cant help myself :smile:

I was thinking you meant a needle valve that adjusted rather then my two fixed rate valves in parallel ?

Yes, I was suggesting an adjustable pilot valve just so it could be turned down as low as possible given wind conditions etc.

The wire idea is brilliant - will test today, thanks much!

That looks great - basically exactly what I’m working on with the addition of an electrical valve on the pilot line too so if the pilot goes out (detected w thermocouple) the gas supply shuts off.

Diagram is swish, what did you draw it with?

Thanks all for the help, updates coming soon…

if your looking for a 0.5mm jet, they are readily available in the form of 3d printer nozzles. they do everything from 0.2mm up to 1.0mm - the cheap ones are almost pennies on ebay

I did the drawings in Visio Professional - lots of differing templates and stencils - not as powerful as CAD but very quick for a diagram like that one

Progress - actually connected one to my bagpipes, worked fairly well though it was impossible to play anything properly while firing as the gas infrastructure got in the way. Also need to get a good switch setup as currently i’d just taped a bit of circuit board to my ribs and used a wire strapped to my elbow. And need to add diodes to prevent shocks from solenoids
.

Ordered some small 3d print nozzles - and now wondering how to connect them to pipe - probably aluminium - any ideas? Am thinking tap them, then screw on tightly - as i’m only wanting a 0.2mm pilot hole I’d guess any leak from the connection would be appreciable in terms of flame size - would folk suggest using teflon tape to get a good connection or leave it? I know it will burn off when it gets hot but might make it easier to screw tightly to fit.

Cheers all!
