Milling machine... am I nuts?

post #1 of 50
Thread Starter 
I've been thinking about getting a small mill drill for a while now to use primarily for casework: general drilling but also cutting neat square holes for IEC sockets and presentable holes for front panels. I currently have my Opus DAC to finish (which will be done when its done, hopefully some time this year tongue.gif) and a few other projects to polish off. The next thing I'd like to build is probably a Bijou, or some other all tube amp. Another project that looks interesting is building a small metal turning lathe, which I could use to turn knobs.

I'm not looking to make any sort of profit from this, but I feel I should get some opinions about this idea and about my sanity. It's a lot of money to spend; building a workbench, the machine and tooling would probably run up to at least AUD$3000. My reasoning with this cost is I'd be spending hundreds on each build anyway, so why not spend a bit more on a new toy, it's all just for personal enjoyment anyway.
I would offset some of the cost of the machine by not getting panels through FPE or similar, but I'd have to do about 10 or so builds to break even biggrin.gif
Again trying to convince myself this is a good idea: I'm not yet married or have kids so now would probably be an ideal time to spend this kind of money on machinery.

I've researched a bunch of different machines and the ideal one for me looks like the Sieg Super X3. The Rong Fu 45 clones look very nice and have a bigger work envelope, but the overall size looks a bit big and impractical for the limited space I have available.

So, am I a bit nuts?
Do any other HF members own a milling machine? And use it?

Suggest you contact our own moderator - n_maher and ask for some opinions. I believe he recently acquired a mill for the purpose of DIY casework.  I don't know if he spent as much as you're contemplating, but he probably has some good advice.  He did some excellent work on a prototype we're working on (take a look at the slots):

How about the this one?

 

Maybe it's not big enough for what you want

but it can be set up with computer interface for CNC work.

Not married and no kids?

 

GO FOR IT !!!

Thanks, I hadn't seen the taig mills. They seem quite small, but then maybe I'm thinking too big. N_maher might have a bit more to say, I'll shoot him a pm.

I think you're a little nuts.

Then again, so am I about this stuff.

Go for it! Forget the cost:benefit rationalizations. Just get it and make some wonderful casework. It'll pay itself off in your happiness and satisfaction. Totally worth it.

Tom, that's just the kind of thing I'd like to be able to do; nice holes for tubes, interesting vents. It would sure beat being on my knees with a hand drill and stepped bits hacking my way through panels. The reason I was looking at those bigger mills was the ability to mount larger panels (I currently have 480x44mm panels) and top panels, but if I just think a bit more about setup I guess a smaller table (cheaper machine) would suffice.

If you got the room in your garage or personal workshop I'd go for a small machine shop sized vertical milling machine with a non-fixed knee (turret mill) [Floor standing].  It's big enough to do even the biggest of cases you want to work on.  Find the local auction house or where the schools get rid of the old machines when they upgrade or get rid of that shop class.  You can acquire pretty good old machining tools that way that need minimal love and care.  Depending on the crowd you can easily acquire them for less than that with money left over for tooling.  You can also find nice ones on Kijiji or in local buy and sell magazines/papers for around that price with a basic tool complement.  Even though some are abused they are still better then the Chinese junk (those machines don't last).  You don't need CNC functions, you can do a flawless job with a little bit of practice.

 

You're not nuts, a milling machine is a perfectly good and useful tool for almost any metal working project; including case work.  It'll get much use trust me.  You'll find projects to do with it you like it so much.  I don't currently own a milling machine.  I lack the space at the moment.  I do have a lot of experience using them, and lathes.  If I had the space I would have one and a lathe.

 

 

 

P.S. Never mind limited space.  Well if you can find a quality english (The best) or american desktop milling machine that will work with your space I'd go for it.  What about knobs? or nice looking feet? There is a small lathe vertical milling machine that can do both.   Think they are call trig lathes it's been a while since I've seen it mentioned, they are table top size.  And you can save money if you avoid CNC and just learn to do it by hand, like a skilled craftsmen.

 

I've seen vintage extremely small table top metal lathes at 3' long, I'm sure there are vintage milling machine at that size that can fit in your closet.

 

Alternatively you could build a setup manually controlled of your own design using a dremel like people do with the diy CNCs.

I'd rather give my case to a company for laser cutting or so. I think it's quite a lot money ($3000) for just equipment and you don't need any special equipment if you are skillful.

 

My father told me: "You couldn't cut that case just by hand to make it lower." Well, I did that just with a saw and a filer and it fits perfectly.

 

And it's just a one example. It just take tiiiiiiiiiimmmmmeeeeeeee.

Well I think I’ve topped $3000 grand easily getting panels done overseas, so no you’re not mad. You also have a market here... don’t know how big, there’s no competition, but I’m willing to give it a crack for starters hehe. I’ve actually thought about this, only two things have stopped me, I know nothing about milling and cash. Besides n_maher, Kerry also has built his own mill, he posts more on the “other” site... would be good source of info.

TheKisho, yeah, I'd love a large milling machine, but I don't really have space for one. I don't have a garage/shed/workshop, but my parents do have a carport in which I can build a workbench with a closable top to keep everything locked up and protected from weather. I'm thinking a cabinet kinda thing where the front, top and side fold back to leave the workbench with the mill (and anything else) on top. Plus cupboards below to store stuff of course. It makes sense in my head, hopefully that's a decent description...
A nice american machine does look like it'd outlive me, but there seems to only be knee and turret mills available. All the mill drill market seems to be filled by the Chinese and Taiwanese manufacturers.
Also, I'm not even looking at CNC. Sure you can cut detailed shapes and stuff with it, but it just seems a bit lazy. Cutting chips myself is where the fun is at.
I've heard not so great comments about lathe/mill combo machines, mostly regarding limited capabilities and that they should really be considered as a last resort if there's no space for a separate lathe and mill. Making a small lathe to do some turning looks like a fun project to use a mill for and I could then make some knobs and nice feet.

John, cash isn't really a problem right now, but I wasn't sure if I was going a bit overboard tongue.gif
I haven't had any milling experience either, but I did do metalworking for a bit at school and really enjoyed it. We mostly used the lathe and did sheet metal work; and got to do some soldering, oxy welding and MIG welding.
I'm not so sure about a Sydney market for milling work with my experience, pieces might come out looking a little mangled at first biggrin.gif but you'd be welcome to visit if you want to have a crack at some milling.

if you have the room for it, especially the height, and access to 3 phase power

you definitely want one of these.

I saw one recently go for about $10k used, delivered with warranty.

 

The rest of them are toys which are ok, but without a digital readout

it makes it very hard to do anything but straight cuts.

Crazy? No, not crazy, but a milling machine really isn't what you're after if panel fab is the primary use case.  What you really want is a CNC router, which is what Kerry built.  It's true that I own a mid-sized milling machine but they require space and a lot of patience to use.  I looked into the smaller machines like the Taig and others but ultimately the tables and travels were simply too small to do what I wanted to do.  So I've got a 400lb bench top machine (with a dedicated stand) and with it I've been able to do some decent work.  It's still very time consuming and as the OP noted the tooling is very expensive if you get decent stuff.  Also, as Kevin noted, without a DRO it's even more difficult to work anything complex.  I added a DRO to my mill and it's simply indispensable.

 

So my advice, do a lot of research before buying anything.

Haha that's just an over kill toy.  Vintage milling machines 60s-70s retrofitted with a digital read out, is more then enough to do a majority of projects for the average man.  (They will run on 240V single phase (The 3-phase machines I've used where never connected to 3-phase power but were still powerful enough)).  Good tooling is a must.

 


 

elliot42 What about English machines?  Where ever you keep it make sure you take good care of it.  Moisture in the air (and blood) will make the table rust.  You want to keep it rust free.  Don't neglect it.

 

 

 

n_maher Some people are incapable of CAM work required for CNC. ;D

 

Yeah it take a lot of developed skill and patience to use flawlessly, but it's by far worth it.  I would of guess they had limitations, I didn't really know a whole lot about them [Taig].  I know they were more of a hobbyist toy.  Good to know.  DRO equipment is a must, but once you use them you cannot live without them.  I agree, if your going to take the plunge and buy this equipment make sure you do the research.  To keep your wallet happy, and yourself safe in general (best to learn how to use them properly.  Don't want to trip an auto feed at the wrong time and panic).
