You can get the EBay couplers with different shaft size either end, thats what I used.

3 phase is much more power than you need to run your mill (which I don't have a problem with) consider using a shear pin in your shaft in case you get yourself tangled up in it.

I havent had any luck finding an ebay one that does 1/2" to 18mm. Its a 3 phase motor because i want to run it on a vsd fron a single phase to give speed adjustment. Was cheaper than using DC speed control.

You could get an EBay 1/2 to 1/2 and drill one side out to 18 mm.

Although my ebay one took a few weeks to turn up.

Get a lovejoy, you wont regret it they're solid as a rock. I think the mob I got mine off was based in sydney, if you google lovejoy supplier/distributor australia you should find em

So after a really long wait for my power supply to arrive, I have finally finished my Grain Mill.

 

[homebrewkid]

Looks great, what motor is that?

 

[sp0rk]

I'd dare say it'd be the one mentioned in the OP

Tidy. Very tidy. I bet you're proud.

Finally got the motor and VSD sorted. There is no marking on the worm drive to indicate gear reduction so I wasn't sure what speeds I was going to get. At 60Hz I'm only getting 18RPM, might be a slow crush!!

Hey Husky
No problem, you will have time for a second drink during the crush

Nice work FB. Pretty much what I'm going to do.
What length of shaft did you get from the coupler to the motor? I see Motion Dynamics sell them.
Did you get the standard 25A or sensing 25A controller?

 

[Crusty]

For anyone that has recently just set one of these up, did you get,
1. The standard 25A or sensing 25A controller?
2. Stainless rod from MD & what length. ( Coupler to mill motor )
Just working out how I'm going to mount mine.

Sensing. I used aluminium rod from ebay as I figured it would be easier to drill. Some zenith galv brackets I got from the local hardware fit perfectly without any additional drilling. Check out my photos a couple of pages back. Definitely not as pretty as some others, but piss easy mounting configuration.

Looks good mate.
What length rod from coupler to mill motor, 200mm to 250mm?

I ordered 300mm as it only cost $11 and just cut to length with a hacksaw.

I couldn't recommend any particular length as your mounting setup might vary greatly.

Cheers.
I think 250mm will be long enough for my setup.
I'll go ahead & order the mill package tonight. I see that MD states that the extra money for the sensing controller is really not needed but I'll make up my mind tonight. Quite a few people are ordering the sensing unit though.

I went the extra and got the sensing controller.

There are probably as many ways to mount these as there are homebrewers who have one! I made up two angle brackets with holes at the appropriate height to get the shaft to align correctly with the mill shaft. The mill itself is mounted on a pair of C sections, with some flat gal along either side to fill in the gap between the bottom of the mill and the wooden box it's all sitting on.

As for the shaft, I got the S/S, but without a mate with the right gear to drill it, it would have been a right *******. I think mild steel rod would do the job, and MUCH easier to drill.

Nicely done.
I think I'm solid on the sensing controller & looking at switching power supplies. I found this guy on ebay in Australia & looking at this 12V-30A 360W version.
I know the 20A is suitable but even MD stated that the 30A will be good & will have a touch more torque. He also warned of some mislabeled units floating around. Anyone see any problems with this one.

Crusty,
I went with the power supply- (Ebay seller) Motion Dynamics links on his web site. Chinese seller, slow boat. But that's the one he recommends. and yes I went the 30A. Also to answer your previous questions, I did go the sensing control (Because there was no other choice at the time) and I think it was 200mm SS rod. and I end up chopping off 100mm. Used a split pin 3mm to connect to the motor and a spider coupler to the mill (Ebay links in earlier posts). I found SS to be fine to work with- sharp drill bit, right speed, right pressure and some lube.

Note; if you are going with the sensing controller his wiring diagram needs updating. Diagram shows 2 external trim pots. 1 to control speed. 1 to control current limit. You only need 1 to control speed as the current limiter is an "on Board" trim pot. I found out after I had mounted everything and a few emails back and forth.

Cheers.
