Help me Motorize my MM-3

[rmullins]

Just got my Monster Mill 3 with the 1.5" rollers and the 1/2" drive shaft and am planning on building a milling station, but could use some help planning the motorizing components. I have read every thread that I can find on here, but I am not an engineer, so a lot of went over my head (if anybody needs help with directors & officers insurance, I'm your guy though).

Now, I take it there are two ways of doing this.

1. Direct driving with a motor. This motor seems to be the go to for people who are purchasing http://www.surpluscenter.com/item.asp?item=5-1098&catname= . What coupler would I need to connect this to the MM? I've got a neighbor who is an electrician who would make sure that it is wired up properly.

2. A pulley system using a higher RPM motor.

As I have nothing except for my MM, I am just looking for some advice onto the preferable method, and what I would need to get everything going. Thanks

Did you get your mill motorized?

Haven't done it yet, but going to follow the parts used in this thread

I'm in the same boat you're in, just took delivery a couple of days ago of my MM. A random place on the 'net has the parts for cheaper, i found them w/ google shopping. zorotools.com,
G1603393 (1.5" for $3.25)
G2490293 (12" for $25.75)

Check my post out on another thread:

Everyone posts about that same motor. IMO it's not powerful enough, although on that thread at the end there is a video of someone using it with the MM3. As per MM, it isn't ideally rated for a 3 roller mill. I would not go less than a 1/4 HP motor. I have a 1/3 HP motor that's 1725 RPM geared down (w/ a gearbox, not pulleys) to 175 RPM and 100 in-Lb of torque. That motor will only give you 40 lb torque. The MM3 needs more like at least 60, as per Fred Francis. I don't see going thru the project of motorizing if there's even a chance it will be underpowered.

Thanks Sanke. I ended up ordering the parts yesterday from Grainger to do a pulley system. It was actually your post that turned me off to the Surpluscenter route
