Save some money by making your own simple magnetic stir plate from parts you may already have around your home. This piece of home brewing equipment is a nice addition to home brewers of all skill levels. I should have done this sooner!

This is the most beautiful DIY stirrer I've found on KZfaq to make it myself. And I like how it's professional put together. The only thing that I change is a on/off switch in the front. So after 5 years, thank you!

Thanks. I eventually did put a dial knob on the front as shown in this subsequent video: kzfaq.info/get/bejne/sNJjkpZmx9fdcXU.html

Great vid Larry! I have a similar cigar-box setup only I used a cheap PWM controller from Amazon for the fan speed control. I also keep an extra magnet wrapped in electrical tape to pull the stir-bar off to the side of the flask so I don't drop it in my fermenter when pitching.

Using your informational video I built two of these thanks for the ideas, they work very well that being said I noticed that you have an airlock on your flask not sure if that defeats the principle of introducing o2 into the yeast to multiply ? ..........

I love the video. I subscribed to your channel and I am learning from you. I do have questions if you do have some time to answer. How long do you have the fan running to complete the yeast starter? And when you pitch your yeast on the brew day would give yeast starter 24 hrs or more to be ready to be pitch or do you give it some more time? Thank you for your knowledge on how to make great beer.

I didn't do the DIY. I'll do my 1st yeast starter tomorrow with a stir plate. It goes from really slow, to a really fast tornado that sucks air & bubbles in. Should I do a calm stir. Or oxygen is good for yeast to start & just crank it up?

@BEERNBBQBYLARRY 3 жыл бұрын

If you're building a stir plate WHILE a beer is already fermenting then it's too late for that batch. LOL Seriously, if you are only doing small batches, you don't need to grow yeast since the vials/packages/packets are usually designed for a 5 gallon batch anyway.

@user-mr9tw6dj6h 3 жыл бұрын

@@BEERNBBQBYLARRY yes. i am trying to be cheap and save the yeast pitching rate. i am trying to see if i can pitch lesser from my packet by letting the yeast multiply in the starter first. by doing starter, i am also trying to make sure if the yeast is starting before i go make my wort. if no, i dont start with the wort. im new to home brew. I am not sure if my understanding above is accurate or correct. I have some table fan motors sitting around, so i am trying to see also if it is a good idea to make a stir platform for my fermenter

Like I mentioned on the other channel they are 20 bucks on Amazon. By the time you order the Fan and assembling it you could have your stir table in the mail

@BEERNBBQBYLARRY 2 жыл бұрын

Looking on Amazon, I didn't see any thing that cheap, but prices must have really fallen in recent years because they'd typically be well over $100; often closer to $150. This one was essentially free since it was mostly spare parts I already has lying around except for the stir bars themselves. Plus, it's more rewarding to make things yourself.
