Thank you, I did a search and that never came up, must have used wrong key words, Sorry!

Long time since I been here, and a long time since I used the dry washer, I am heading to Vic in a few weeks, with luck it might be dry around Ararat, Can I use the dry washer in Vic

Electronics goes over my head, but a quick search and the appears to be plenty of info, here is a start. http://www.learningaboutelectronics.com/Articles/Overvoltage-protection-circuit.php

I have finally finished all I need is some dirt to try it out, I don't think our local red desert sand is really the stuff to try it out on. I changed my mind on this job more than any other, I finally went for wheels on the cam. and I settled on calico for the riffle tray. Calico in Australia...

Not sure!

There are probably others is Melbourne but the locker group always have a good range and quality to pick from http://locker.com.au/general-industrial/wire-mesh-general-industrial/

Bloody hell I been around the cape of Good Hope on this one but I have finally settled on this.

TIG welding bit of an art to make it look pretty, I have TIG welded a lot of aluminium and stainless over the years and can say I will never produce art work, as long as it hold or does not leak is all that matters, function over form anyday! however the more you do the better and faster you get.

Whats can I say, I am at home in my shed more than anything else! I have never seriously prospected or fossicked but I am gearing up to hit the tracks once my wife retires. I am far from completing this little project however its well under way. My wife said copy a plan but no I must reinvent...

I would not call it costly (cost about $10 for a strip 300x1000. I am not sure what you mean by tight enough. this mesh I have used in irrigation water filters its pretty robust and consistently woven. you can get 125 micron. sorry I can't give links.

I am very new to this stuff and the only mentor I have is my wife and she knows nothing! I have spent hours upon hours searching the net for information on building a drywasher (puffer style) like most topics, much is just regurgitated on the net. I am no good with stuff like CAD and for that...

Hi all, I have been reading threads here for some months now and thought I needed to ask some questions, hence the registration.
