Primo Stir plate made easy

[Squirrels]

I would like to be added as well. If it takes more than a year, and you feel like keeping on doing this I would really love to have one!

 

[user 84304]

Add me to the list, if you would, please. If these things start falling from the sky, maybe I'll get one too? At any rate, you rock for even starting this, man.

For those that are trying to get their magnets to work here's the way mine was set up. I posted a link a few pages back but some haven't seen this yet. I've also been able to slip some spacers in between these so it doesn't use as many magnets.

Keith, how much pull force is your set-up and can you advise on how much pull force is needed to hold the stir bar? I have been looking at neodymium magnets but I do not want to buy more than I really need.
I am looking at a 2"x1/2"x1/4" stacked on a 2"x1/2"x1/8" magnet which gets a pull force of about 45 lbs. Is this way overkill? I have no idea. Thanks.

Man I'm sorry I didn't see this question asked. I've never measured the pull force but I have tried to add washers in between each magnet just to take up space and use less of them and it didn't work so well. I also tried one stack of magnets and that would only attract on side of the stir bar so that pretty much sucked. It also can be tough to center the stir bar the way I have it pictured above sometimes. It just might work even better by creating a little space between the 2 stacks and use 5 minute epoxy to hold them.

From what I've seen with my own starters is that there is NO need to pull a vortex at all anyway. Shake the wort to aerate it then simply mix at 400rpm for a day or two to keep them yeasties moving and it works like a charm.

I would certainly love to be added to the list. I am local (-ish) in NOVA, so could even meet somewhere if you prefer.

Thanks!

 

[thepirho]

Well, I would like to have one. My paypal is waiting. I would like to take it apart thought. If you have enough of them left. Cheers, and thanks

 

[cfrazier77]

What you are doing is great! Please add me to your list. Thanks!

The reason I was asking is because I use either a growler or a 1 gal wide mouth jar for my starters. Both of these have curved bottoms and I was thinking of using of using a barbell type stir bar. I would think the more "pull" you have, the better the bar would hold to the bottom of the jar.
I do have a plan to get a 3000 ml. flask and use a cylindrical bar but I'm not sure if I should get a 1" or 2" bar. I read that sometimes a 2" bar contains two magnets and will not work with my 2" single magnet. I guess I will just have to fiddle with it until I find the right setup.

7 to go!!

Big thanks again to Bigbeavk, I used mine this weekend and my batch was fermenting within 3 hours.

 

[tbel]

Nice one tbel! I hope to get more soon! Now can you fill in some details?
What magnets did you use?
Stir bar size?
What rpm were you running in the video?

I ran it on 600rpm to aerate but on 200rpm to keep the yeast moving for 2 days.

 

[FRS]

I'd like to be on the list if more of these show up!

Looks awesome!

Nice one tbel! I hope to get more soon! Now can you fill in some details?

What rpm were you running in the video?

I ran it on 600rpm to aerate but on 200rpm to keep the yeast moving for 2 days.

I haven't used it for a starter yet but in the video it was running full on 1200rpm.
The magnets were some I had laying around I'd say about 3/8" dia. round fairly strong. I stacked 3 on each side so that the ends of a 2" stirbar would be at the outside edge of each of the magnets. I took it apart and very carefully marked a line through the center and the distance from center for the magnets. I've found from previous experience with striplates that the better you center the magnets, the less likely the stirbar will be thrown. You can be less accurate and still have a functional machine. I've seen where alot of people (including myself) keep trying to add stronger magnets to prevent the bar from being thrown when simply placing the magnets more accurately would take care of the problem. (at least that's my Opinion)

I still plan on making modifications. I want to get some magnets that are a little stronger and raise them up so that they are just a fraction of a mm under the table. I have a piece of plexiglass that is cut to the same size as the top that I'll then mount (hoping to keep potential messes out of the unit).


Just wanted to add that the noise in the video is all from the high speed and the water reaching the stirbar. It actually runs very quietly!!

 

[Zorin]

I know this is shot in the dark, but can I get added to your long list of recipients?

Thanks,
Z

 

[eleets2144]

Attached is my video and a pic of my magnets. The noise is due to my 6L flask not having an even bottom.

 

[Peter_h]

Can you put me on the list?

 

[Latka]

Could you please put me on the list as well? I'm horrible at remembering to shake the starter yeast every hour.

 

[tbel]

Attached is my video and a pic of my magnets. The noise is due to my 6L flask not having an even bottom.

So can I ask what size magnets you use and where'd you get them?

 

[milldoggy]

Please add me to list if you are still taking people

 

[eleets2144]

Neodymium Magnets N45 1X1/2X1/4" NdFeB Rare Earth Magnets :: 1/2" <...

I use a 2" stirbar

 

[bodhi314]

Did these dry up?
Still interested if there are any out there.

And happy new year all.

 

[Bigbeavk]

There will be more sooner or later. I just posted one that I found on ebay in the classified section for those that don't want to wait.

I'd like to be added to the list. This would be awesome for the clarifying stage in wine making!

 

[Bigbeavk]

FYI this current list will probably take well over a year or 2 to fulfill but I will keep on going as long as I can. I think the list now goes up page 7 or 8.
Hang in there ya just never know.
