Oh yeah ... Just try doing that yourself, before recommending such an unsuitable device to others.
Would you care to upload pictures of OA vapourisers that you've made yourself and have worked ?
I fail to understand why people are continually trying to use novel heating devices, when some of us have already spent many fruitless hours playing with such things, and are more than willing to advise others in order to save them from wasting both their time and money.
For example - I once tried to use the ceramic elements from 50W soldering irons - only to discover that one wasn't enough, so I started on a vapouriser design which would incorporate two. :
That's as far as it ever got, for while making this I 'discovered' diesel pre-heater glow plugs - and now I wouldn't even consider using anything else, as they are PERFECT for the job.
So why not take advantage of the experiences of others ?
Only two forms of viable DIY OA evaporators have thus far emerged from countless hours of experimentation: the copper tube & gas torch method, and the use of Diesel pre-heater glow-plugs. Just 'do a Google' to check this.
Anyone playing with anything else is almost guaranteed to be wasting their time.
