[QUOTE="WalnLiz, post: 22476, member: 147"] G'day Drewe, The second pic is closer to the angle you need. Remember its a combination of angle and water speed that determines the fine tune. The pump needs to deliver enough water so that 20 -30mm runs across the riffles. You need to tilt the box so that the riffle section remains about 1/2 full. The Sapphire section is specifically for gems only and the lower end of the box needs to have sideways shaking about every 10 shovels to pulsate the Sapphires/ Zircons/ Spinels to the bottom of the screen. You cannot work it the same as the gold only mesh ( sloped expanded ), which requires no shaking movement. Send me a PM and i can explain in detail the procedure for each system. Cheers Wal. [/QUOTE]
