Need help, buy or build to cut steel, stainless steel, titanium etc

Welcome to the forum fatguyslim.

"I think" you need to catch the CNC bug!!. once you have caught it, it changes your perspective on how you go about doing any job. Your initial requirements are a perhaps a little High for somebody starting out, but that doesn't mean that you should just give up. There is a entire other world just round the corner, that as you say, will vastly aid your goals. Perhaps see if you can buy yourself a cheap machine that meets your storage & workshop space requirements for now. Something that perhaps is only any good for cutting wood and plastic. That way you can learn the software experiment and see just how powerful it is.

Then, once you have a little confidence, you will see just how easy material you think "wont ever bend" bends and flex's before your very eyes, and its with this hands on experience you will be able to see clearer the points that have been made above. Then, Like some of the more experienced members have suggested, I would buy myself a solid milling machine.. something off ebay etc, as a milling machine, then convert it to cnc, that sounds like a huge job to a newbie.. which is why im suggesting you buy yourself something small so you catch the bug learn the concepts, then you can use your "hands on" skills previously described to convert a machine to your ultimate requirements.

They come up often enough, you buy it cheap learn all about it, no doubt you will be able to sell it on once you have finished playing!

Im perhaps too far away (leicester) but you would be welcome to come and play with my wood router which although nothing like your requirements, would give you the enthusiasm you need to get on with it.

Please dont give up, or put it off. I wish you all the best.

Ok lets just backup here.!! . . . First George sorry for Snapping I was out of order for that, but of late it seems my words are being twisted out of context.
To be accused of being Discouraging is somewhat insulting to me because often I'm the first to Chim up and encourage people, freely giving advise and often getting involved in some way or another off forum. (Which for the Record I'm going to offer my Hand to Fatguyslim via PM.)

I never said give up on CNC I merely gave a very realistic dose of reality to someone with no experience. I also gave some very good Alternatives and recommendations on correct machine design if the guy did continue down the DIY CNC route. . . I then wished him Luck.!!

So Between this and other Post's where what I'm posting gets twisted or misread I've decided I'll be taking a back seat from now on and refrain from posting. I'll be around just not offering advice. (well not publicly anyway)

Happy CNC-ing to all. .

(Oh before those that feel the need say it.! This is not me throwing the Teddy out the Pram it's me saying enough is enough and I don't need the hassle.!!)

Hi Fatguyslim,

I'm not sure if the few last posts have piqued your interest again or not, so this question may not be relevant.

But if you were to design and make your own bike bits for these higher stress areas and sell them to the public where do you stand in terms of liability in case of failure? Would you need to carry out your own stress and durability analysis on those safety critical items, and is that something you were planning anyway?

EDIT: Crossed with your post. Ignore - BS/EN testing mentioned in your post . . . apologies.

Not sure if you read my last post but my bikes are currently going through BS/EN testing for MTB, Road and City frame so if they pass this testing then i can get public liability insurance for my bikes.
