hi
i too have my eye on one of these spindles albeit from a different seller (cheaper) but i have delt with chai from linearmotion many times ( bulk orders of bearings/ shaft support ect) & it is always very smooth & also fast too considdering it is from china, what are the advantages of these spindles apart from the high speed? one thing i am worried about is the ceramic bearings in them one tool crash & they could be reuined how are you intending on mounting it lee? single or double mount
