Beware of the cheap Chinese 4th axis kits. One came with my Laser Cutter, and they all look to be the same generic design. Thick aluminium plate with the main bearing pressed into a recess and nothing else holding it together :bugeye:
A modification was in order ! (and duly executed)

Things like this look attractive.

Price is low enough that you could scrap it for parts and it'd still be an OK deal..

That looks very cheap for a harmonic drive version. I was lucky that I acquired a harmonic drive from a piece of scrap equipment for free but mine's really too low geared at 200:1. 50:1 is much better. Mine is a 100mm centre height with a Myford nose so will take a faceplate or 4" chuck with no problems.

Agree, it seems cheap. My last buy (used) was about AUD500. But it is quite small???
