Ale-8(1), You have a point! Does the name Rube Goldberg ring a bell? I know it looks pretty shoddy but I have been using it for about 5 years and it does work exceptionally well.

Several years ago for Halloween, my wife bought this crazy electronic gizmo that is a candy bowl. When a trick-or-treater goes to grab some candy, a light sensitive cell picks up the movement and a hand comes out of the bowl in addition to a scary "Happy Halloween" voice. After a couple of uses, the cheap ass thing broke so I tore it apart to see if there was anything worth putting in my junk box. Turns out, the geared motor for the hand gave me an idea and the above is what developed. I can't take full credit for inventing a motorized trickler ... Frankfort (Midway USA) used to make one but it got discontinued .... probably because there weren't many people as crazy as me that wanted to buy one.

Well, I'll tell you what. Iowegan, you are a man among men.

Aside from that, I ordered that Mack 20 from old will knott scales (something like that) along with the a/c adapter this morning (reference above post). And I already received a UPS tracking number (@ 0948) and all. It is already on it's way to CA! Talk about fast!

I don't think it's shoddy . . . it's a nice piece of work, and three speeds, at that.

If Rube had made it, it would be the size of a refrigerator and be steam powered.

This is the slickest device I've seen to date.

ColColt, If you want everything in one unit, this is the cat's ass. The AUTOSCALE is intended for extruded rifle powder but can be adjusted for heavier pistol charges too. It doesn't work very well with charges under 10 grains.

After leveling the unit and filling the powder hopper, you start by setting the scale poise weights (identical to a RCBS 510) to the desired charge weight. When you press the green button, a high speed and low speed auger start dispersing powder in the pan. When the charge weight gets close, the high speed auger stops and the low speed auger continues to trickle until the scale pointer is dead on the mark, then shuts off. You are then ready to pour the powder in a prepared case. For a 50 grain charge, it takes about 10 seconds to precisely measure out a powder charge. I've had this AUTOSCALE for several years and use it when loading rifle ammo on my Rockchucker. It works super and accuracy is +or-.1 grains. The newer digital scale auto powder dispensers work much the same except the scale is digital and you set the desired charge weight with a key pad.

The nice thing about either the balance beam or digital powder dispenser is everything is in one package. You don't pre drop from a powder measure then trickle up like in the Youtube .... just push a button and a few seconds later you have a precision powder charge.

The electric trickler I made works much the same as the one in the Youtube video, but it sure doesn't look as nice. Mine has three speeds ..high will drop about 30 grains per minute, medium drops about 18 grains per minute, and low drops about 6 grains per minute. Once you get the hang of it, you can trickle up a charge on the Mack 20 scale accurate to .02 grains and rarely go over weight.

Here's my old AUTOSCALE:

That is super! We've come a long way from my old Pacific C-press and powder scale. Too bad they don't make them that will measure 5 gr and above for target revolvers. Most of my charges run from around 4-9 grains of several different powders with a few running 13 gr or so. Either way, it would sure beat a standard powder measure and scale setup-absolutely awesome.

I have an RCBS 1500, but, I've yet to set it up as I haven't started producing rounds in the quantities where it becomes usefull. Someday (when spring breaks) I will probably get around unboxing it and setting it up. Looks like it will fill my needs perfectly. I load one round at a time, anyway.

Yeap, mate you're right. The calibration weight that comes with the scale doesn't necessarily be of good quality, it surely depends upon how much you've paid for its accuracy.
