Re: Can you trickle to an acculab vic123?
My experiences: using a conventional trickler w/ an Acculab VIC123 didn't work very well as most have too short of a tube to reach out over the scale pan. An industrious individual could rig something up, though...
I got a Vibrashine trickler, which while very cool - you can get single kernels hopping down the clear tube, which is long enough to reach - if set up on a box/block, but the vibration that close to the scale drove it batty. To add insult to injury, I think the slowly changing trickle confuses the scale into thinking that the zero is drifting, then it starts trying to compensate - then it really *does* go nutty on ya.
For me, the simplest 'trickler' that worked consisted of a plastic picnic spoon and a spare pan w/ 2-3 cases of powder in it. Throw/dispense the charge, see how far low it is - say .12gr - scoop up 5-6 kernels of Varget w/ your spoon, and dump them on the scale pan all at once, and let it settle again. Odds are you'll be w/i +/- 1 kernel. Dump the charge down the funnel and carry on. Sometimes it works a little better if you lift the pan, toss the 'extra' in and set the pan back down. If you over threw or over trickled, definitely lift the pan up off the platen rather than go rooting around in it while still on the scale.
I used to have a pretty good 'feel' for how much powder to add or remove - used to just pinch and roll the kernels between thumb and fore-finger to get the right amount in there. Worked pretty good, too. Got too many dirty looks from a friend, so I amended my heretical ways and started using a spoon. Even licked it clean first
