Just a curiosity, has anyone ever tried and had success using a glow plug from a diesel engine as an ignition source?

I tried a diesel glow plug a few years back, unfortunately I think the air flow over the glow plug where I had it was sufficient to cause it to cool down somewhat, it did light off more often than not but was quite unpredictable and made for some "exciting" starts...I now use a proper aircraft igniter and propane to light off....it's idiot proof and works every time.
You may have more success if you dribble liquid fuel over the glow plug during start like they do in smaller RC turbines, they're very reliable these days and always start "soft". I'm actually playing with the idea myself as I'm now a bit tired of carting an LPG bottle around with me.

I’m using a hot surface igniter on my build. Whilst I havnt had the engine running yet, combustion chamber testing with a leaf blower using diesel ignited every time.  |

I tried but it didn't work good for me. When outside the combustion chamber it would mostly ignite, but with all that "wind" inside it never ignited querosene. I think it is more a design problem. Mister ausjet above had success.
