G'day Bryan,

I'm an Electronics Technician by trade and agree that nothing stinks quite as bad as burnt electronics. The smell lingers too.[:'(] With proper component selection, maintenance and no abuse, electric has too many advantages to ignore. Having said all that, don't use steel hardware as it will rust! No oil to keep thing un-rusted.[&:]

One thing to note from Glenn's photo, I would replace the aluminium tubing with anealled copper tubing. Tom Prosser gave me that tip. The aluminium after time will crystalise and then crack. Brass tube apparently splits. It's the vibration that does it over time. Kind of like bending a wire until it breaks if that makes sense.

PS. I will be seeing Chris Swain today. I believe you met him at the Worlds in Portugal. He's up for a one-day comp at my club this weekend.

Cheers
Jason.
