Time for a Reality Check and encouragement to New builders.!

[JAZZCNC]

You've used this term, DIY, many times before, and what you say about it here is true, but maybe some people are trying to build a 'professional' machine ?

Yes I'm fully aware of that Eddy but in which case they are doing it wrong anyway.? 200Kg Gantry with cheap 2.2Kw router is no use or ornament as a professional machine and woe fully under powered for the strength of the machine.
Same goes for anyone building a moving gantry router style machine to mill steel or aluminium to a professional level. Compleltely wrong choice of machine.!!
In 95% of the cases on the forum most are not building with professional intents but to be the best it can be. Which is fine but it can be all that with the components used and still be built with much less strength and fuss.

Not forgetting that real machinists use steel...not ali!

Well that explains why you used MDF then. . . . But actually professional machines Milling machines mostly use Cast Iron or Man made composite materials along with aluminium.

There's no such thing as over built and when I build somthing, I always over build, with in reason of course. Code may say 4x2 but there's no reason not to use bigger if you can.

Well depends on the design doesn't it.? Space shuttle wouldn't have got far if that was over built would it.!

My point isn't about over building and the " Within reason" comment is very apapt.!
Those over built machines are not within reason they are well OTT for work they are being used for.

BUT My point is that these builds WILL BE OFF PUTTING to new potential builders and I'm not trying to discourage anyone from Over building "With in Reason" and more trying to encourage and let those sat on the side lines know that it isn't required or needed to build like this to get a very capable machine.

You of all people should be encouraging the same NOT jumping on me.! . . After all this forum as been made what it is by mostly DIY Members.
