Stray varget kernels, autotrickler v4

[fattybinz]

Got a v4 with an area 419 powder cup. When throwing varget, I'd get a stray kernel or two on the fx-120i plate every 7-10 throws. The funnel was centered over the cup. So I figured there was too much space between the funnel and the cup and the powder was hitting the edge of the cup and falling out. I 3d printed a funnel that extended farther down to reduce that space. I think it helped, but I still get stray kernals every ~15 throws. It's really annoying to have to check the plate from every angle after every throw for fear of there being a kernal or two on the plate throwing off my zero. Anyone run into this? I can 3d print an even lower funnel, but I wonder if the problem isn't that height, but maybe the kernal are falling too fast bouncing out of the cup or something. If it's bouncing out, maybe I lift the cup up so the powder isn't falling as far/fast to reduce odds of it bouncing out?

For all my loading with cups that were 'nippled' like the 419 you have, I always found having the drop hole just slightly off center worked better at reducing any splash. 419 had their aftermarket spout that was off center and I loved it. So you may try printing a slightly off center funnel just to see.

However I now use these cup https://ingenuityprecision.com/product/ingenuity-powder-cup/ and because of how they're made with a spongee base (not rubber but you can push the bottom and it's flexible) they absorb the impact of the powder and I don't get any bouncing of any kind. Just another possibility to help you.

I just created a dome to cover the pan so when a stray kernel does escape it is pushed into the gutter and don't even notice.

This seemed to eliminate the random stray kernel.

Offset the cup so the powder hits the side of the cup, not the center.

Cool! Do you mind sharing the 3d file for this? Does the space fit the area 419 cup?

Do you mind sharing the 3d printer file for this? or is there somewhere one can order this?

Where to purchase? Are you printing yourself? Selling?

I was planning on listing them for sale later this week, I have set for the Autotrickler which includes the pan cover, powder catch for changing powders and a o-ring sealed powder cap. Shoot me a PM if you would like to get a set!

Varget is like flubber... it bounces everywhere!
Thingaverse has multiple cups with convex bottoms that will fix your issue. I went through the same issue with Varget and it fixed it right quick!

A kernel or two on the platen shouldn't matter, as I think the V4 auto-zeroes as long as you're +/- .02gns (might be .04) at the start of the cycle. An email to Adam should clarify that.

That would be based on the scale not the trickler and my A&D FX 200i does not self zero.

My fix to the errant kernal problem. Took the large diameter platen off and replaced it with a smaller diameter aluminum platen that is smaller in diameter than the cup. Any splashes never land on the little plate.

Thats the best first step.

I switch to his cup too, but N140 and N133 don't make it to the cup with the original funnel. The baffle just has them bouncing everywhere. I was going to try 419's funnel but they don't list it on their website anymore.

Years ago now, I bought Area 419’s full upgrade for the Auto Trickler and have now upgraded the trickler with an Ingenuity trickler setup {that was absolutely worth doing} and still get an occasional bouncing granule of powder but seldom does it land on the delta shaped 419 replacement platen and a 6”long of tweezers is always on the bench for just that purpose to remove it. If it is on the platen than I just drop it into the cup before dumping the load into the case as it was part of the total weight… No problems, any grains not on the platen were not weighed and can be ignored.
419’s beautifully machined items are miles ahead of all the printed bits that came with the original Trickler setup and I think that there was some sort of falling out with the Canadian manufacture and 419 as well as the big changes to the structure of the Auto Trickler that caused them to just stop making the replacement bits…
As for the auto zero, my 120i will zero if only .02 grains out. .02 = 1 granule of Varget… just about nothing in the whole scheme of the entire load.
Just a short delay before it will zero and throw.
The offset spout mentioned definitely helped with bouncing grains of powder so if someone is making them by printer and you can no longer get one from Area 419 that would help solve the problem.
I may go ahead and buy an Ingenuity cup if my order for one to their whole setups is delayed much longer… Just to see how that works.

It would be based on the system (scale + V4 + controlling phone/tablet), not just the scale.

The trickler does not weight anything so you might want to read the instructions for the SCALE. Go ahead and test it by dropping a kernel or two on the plate and see what happens...it does NOT re-zero.

Sir, you are missing my point. The scale will, indeed, be affected by a kernel on the pan. The system will correct for that. The original post was about using the V4 system, not just the scale.
