    dicklaxt got a reaction from Geowizard in Small Trommels - 1 Yard Per Hour   
    I'd think of using UHMWPE as its a proven slurry pipe, tougher than a boot but may be pricey. It will beat PVC hands down.,,,,,,,,,but then again what do I know about pipe,I used a piece of it for a project onetime and it's hard to hurt.

    dicklaxt got a reaction from Geowizard in Extremely Fine Gold Recovery   
    We, USAF active duty members in Alaska back in the late 1950's did a lot of stupid things in our quest for gold.When panning for gold, the remaining concentrate of heavy sands and fine gold presented a problem,separating the gold from the sand was a tedious undertaking with tweasers, kind of like picking fly chit out of pepper. An old established miner of the times told us of the why's and why not's(danger's) of using mercury to recover the gold. We midnight requisitioned some mercury switches from the electrical shop and drained them,smile.. the use of a two gallon mayo jar filled with  a small amount of mercury along with the concentrate when positioned on a motor driven paint shaker/mixer produced a gold amalgum glob. We had a 5 year engineering graduate  in our group who we all thought was the smartest guy in the world. He came up with a method of  making a mercury retort using a plumber's lead melting pot & blow torch and misc parts & pieces we had available at our radar site. I sure can't remember the details of how that rig all went together or worked, but it did work, allowing us to separate the gold and recovering most of the mercury as well.  I know we set it up outside and used a big fan to blow any escaping vapors away from us. It's a wonder we didn't kill ourselves from mercury poisoning. I'm sure we didn't expose ourselves or the surrounding atmosphere to enough vapor or skin touch to hurt anything but I'll bet we sure violated EPA guidelines to hell and back. I think back now on all the dumb tricks I did growing up and it's a wonder I survived.

    dicklaxt got a reaction from Geowizard in Ophir, Alaska 1956   
    I thought that post title might get your attention ....smile.
    Hi guy's and gal's my name is Dick and I am an old man(78) retired in Texas. I met up with Geowizard on another forum (non gold type). We struck up a conversation about Gold and Ophir. To make a long story short, I was stationed at a US Air Force radar station near Ophir in 1956 and tromped around the old tailings that Geowizard speaks of in his writing's. 
    I will be following his steps,failure's and success this season at and around Ophir so if you see my name here and there you will know why I am here. I wish I were able to be an active prospector with you all as it has always been a keen interest of mine. Yes I did find gold at Ophir in 1956 and again in 1963 when Uncle Sam sent me back for a second tour of duty.
    Have a good day,,,,,,,,,,,,,,,,,,
