Maybe I am going through a typical path:
Step 1) Registered on CNCZone
Step 2) Started reading the project logs
Step 3) Bought a CNC router
Step 4) Reading more project logs, trying to make my router better
Step 5) Bought a bunch of parts
Step 6) Started Designing Machines
Step 7) Having friends making parts
Step 8) Thinking about buying a manual milling machine to make parts by myself ...
Now I am at step 8)
Seriously thinking about a manual milling machine. I think this is a right way to start. I am an electronics designer and consultant. Believe it or not my whole house is in solidworks, even got my faucet modeled.
Again, I will say I learned a lot from this forum.
So back to the topic. I am buying a manual milling machine. It will be in the basement of my new house. Budget is $2000 to $2500. For good reasons may bump up the budget.
Thanks for HOSSMACHINE's Mill Comparison Sheet. I started from that sheet and narrowed down the options.
This is his sheet:
Because I am planning to use the mill to machine parts for the vertical CNC machines or routers. I think I will need the long X travel. Just talked to Pat at Machine Tools Warehouse, he got a few in stock and new batch coming. I am planning to get the MD001(IH Clone) in May or June. The price is $2300+$150shipping. Price looks good to me. and I know it is only the start...
Anyway, just want to have a good start point.
Everyone in Hoss's sheet looks pretty good to me. I also search the zone with those model numbers. Each one has its pros and cons. I picked MD001 pretty much by the travel, and of course it looks good!
This will be my first milling machine, the closest I have used is the drill press (I also use my CNC router + MACH3 doing 3D cut on wood and plastic).
Anybody with manual MD001 or IH 12Z can tell me if I am looking at the right machine to building VMC's?
The travel of the VMC will be in 12"x8"x4" envelope. accuracy aiming at 0.002"
It will use HIWIN linear rails.
Gee, bonmotwang you're doing your home work.....as you're in research mode have a look at the option of a three phase motor as opposed to 220V single phase, the three phase motor consumes less current than the single phase and your 2HP single phase will run up fairly high electricity costs.........and you could use a single phase in and three phase out inverter (VFD) to run a three phase motor from your 220V single phase house hold power supply........
Unless there is a lot of heat somewhere, the power input to either case approximately equal if the power produced is the same.
My power meter measures POWER not current.
There may be a lot of other reasons for using 3 phase, but saving money on electricity is not one of them.
Just moved into the new house. After settle down, I will order a BF20L from MTW, and CNC it.
New plan :-D
You know why? Those building threads you guys posted made me more confident to this direct CNC way.

What have I missed here? and how do you measure power?

So, a VFD will make no measurable difference whatsoever in your electric bill.
Slightly off-topic, but I wonder about it a lot: Why can a 1hp DC motor be huge, and another, of the same hp and speed rating be significantly smaller? Is the large one (like a 56 frame) larger than it needs to be? I wonder why people don't use the 1hp 56 frame DC motors to drive spindles on these mills? Can you tell me why that might be? I'd like to do that if there isn't a problem with it. Is it all in the controller?
