Hi dpex. Justa quick note on the Spectra you bought. If it has a pro-con pump it's not a 7gph unit. It's at least a 12-13 gph unit perhaps more. If it's a 220 powered unit most likely it's even more. Let me know what model it is and I'll send you all the information on it. 2K is a great price if all works well.
Best, Tellie

Heya Tellie,

I just scored at 7GPH, Spectra, with everything including a Procon SS feed-pump (apparently the procon feed-pumps can be a bit unreliable) from a marine engineer who is real short of cash. Price paid??? NZ$2,000.

Hell's teeth. When I visited the Spectra agent her in Auckland I was told they want NZ$1500 just for the RO membrane!

The unit runs on 230VAC, so I'll have to get an inverter, but I want one anyway to run power tools.

Also, today, picked up a two-burner. Origo denatured alcohol stove. This thing is reputed to run for 6 hrs, flat out, per burner, on one litre of fuel. I'm running a test as I write this, to see how this unit compares with my home electric stove to cook a pressure-cooker full of stew.

For convenience of space my intention is to gimbal the stove using a counter-weight as opposed to having the axle-point above the stove, as in hanging gimbals. What do think of that idea?

Cheers
david.

Hi Telie,

Thank you so much for the offer to help. My direct is dpex at xtra.co.nz, where the 'at' is actually the normal icon. But for some reason this site denies permission to use that icon.

And my name is David.

My plan is to follow, very closely, the Leo Litchfield design.

Cheers
David.
