Accurate Strong Gantry

[vargai]

You can draw to crazy levels of accuracy but when it comes to drilling a hole or cutting to 0.1mm using the kit you have in your garage!???
With my cheap drill press, cut off saw and stick welder I have needed some tolerance building my frame and I have seriously taken my time!!!
You are doing the right thing sharing on here though you will get some v helpful advise.

Thanks for the attention and care.
I have to share my inner motivations and means for the best understanding.
I.e. Silyavski thinks I bite off more than I can chew
I am amazed at the way you guys build very good machines.
As for me I want to apply machining where necessary.
Perhaps I am not the only one here with this. But personally I feel a pang of conscience because this is not really DIY method and do not know where is the border.
