Thanks gents,
Dek, No worries. I've done lots of stupid in my life but I always tried to avoid smoke of any description

Specially white stuff that is toxic!!
Big box of lenses and prisms.....Sounds very intriguing
Clicky switches are soon to be incorporated in some test builds.... House comes first though!
I'll be over soon ish... Was meant to be on Monday... Just with a 1/2" of snow my cars butt won't stop wigglin!!
Might get over there.... Will let you know if I am

David, machines like butter (with an ultra sharp tool) much lighter than aluminium ~1/3rd.
It was fun making all those swarf swirls.... But that was partly due to the fact I knew I was gonna light some of 'em after

(first time I've had the fun of lighting it since school too... Although that was a mere 24ish years ago

)
