Grain Mill Options

Yes I know I have a MM2 !!

I meant finding a local fitter and turner to make a once off mill to your specs...

THIS ONE?

That's the one.

Yep, we are on the same page. To get the same quality of the mill including the knurling is very hard locally.

I got inspired at the start to build my own on a tight arse budget

With the help from others here to inspire me it worked out real well it just takes time to sus out things

I think it was Brown Dog he told me to nickle plate my rollers which cost me $65 everything else was scavanged up at work

There are quite a few on here who have made their own & mine is a bit rough but it works

A rolling pin.

Yep that would work but after 2 brews I went for the truck windscreen wiper motor to drive my rolling pins

I've been trying to get a mill motor setup for a while;

How many brews worth have you pushed through using the windscreen wiper motor?
Are you running 12v or 24v?
How many amps is the power supply?
How many RPM does it run at?
IS it up to the job, or now from experience would have gone for something more powerful?

I have a 3 roller MM and so far the hardest part has been building a hopper and figuring out how to motorize it (drill vs pulley arangment). I havn't got it running yet so I can't comment on how well it works but if you are not very handy with tools (like me) you might need to factor in either getting a mate, or paying a fabrication shop, to knock up a hopper and motorize it for you. I almost went the marga mill due to the ease you could make a hopper for it.

I am trying to build my own hopper with MDF and its turing into a bit of a shitfight. I guess thats all part of the fun...

This website will help you calculate the dimensions of your hopper. It can be a PITA to try and figure out all the angles etc for a pyramidal hopper. This one even tell you the volume it will give you. http://www.ajax.co.uk/PyramidHopper.htm

information that would have been handy before I started.... Guess i should do a bit more googling before starting these projects. Oh well...

I just ended up guestimating which has probibly made it harder then it should have been.

Sorry i couldn't have helped earlier. It might help someone in the future, who knows?

I built my own mill with 65mm rollers and gear drive. I used a $12 stainless mixing bowl for the hopper. It holds 6kg of grain and you can cut out whatever shape hole you need in the bottom with an angle grinder, pop rivet it onto your mill and off you go.

I have a Crankstein CGM-2A which I mabe up a hopper on my table saw. The crank shaft has a female hex socket in the end and I use my Shinano 800rpm driver to turn it with my regulator as a speed controller. I burnt out my brothers 1/2" Bosch drill trying to mill as it did not have the torque.
This pnematic setup does it with no effort at all.

You can throw away the megaphone now - no need to blast it at the kids to turn that crank!

Hey JD you need a mega phone around here to get them to do anything

Kev Ive done about 15 brews now no probs 10amp power supply 12v

RPM = 120xfrequency
number of poles

not sure what type of motor universal series anyway I'll get back to you on that one

Mate it has worked real well took a while to sus my gap settings 1.4mm at 80% for easy lautering

Its not a fast crush but about 5 mins worth

In the end it cost me $65 but its not a mill master but it does the job & I can brew so Im happy

heres a pic of the power supply

Sounds good, I'm not worried about a fast crush. I can hit the switch on the mill and do other things, and a slow crush is a clean crush. If you can find ot what motor that would be great, thanks

I have read in one of my brew books that it recommends the mill to do no more than 100rpm from memory. But then again you get rollers of varrying diameters.

 

[rude]

mine are 50mm rollers the only problem I have is the idle roller sometimes stops so I just give it a spin & away I go

But I am still doing other stuff just hear the noise now & again at least once a crush especially with wheat malt with just ale & crystal malt usually no probs
