AndyUK's Build - 1.2x1.0m Gantry

[AndyUK]

I take your point about the chinesuim (lovely word by the way. I'm rather proud of having invented the word 'polycrapoline' to describe the cracked-within-weeks material used in some HV breakers I had the misfortune to work on many years back).

Chinesium is one of many AvEisms - search AvE on youtube, you're in for a treat. I suggest starting with some of the BOLTR (Bored of lame tool reviews) which are extremely informative teardowns and tests of various powertools. He is a bit of an interesting character, but well worth watching. And of course ThisOldTony needs a mention - especially his CNC build videos.

It's for each of us to decide the level of risk we are willing to accept in our home workshop.

I totally agree, and please don't take my words as any endorsement or critique; merely just my rambling commentary on which failure modes I think your suggestion protects from and those it doesn't.
