i bought a pair of those 708A bearings but never got around to implimenting them as i ended up using the larger spindles most of the time and the skate bearings seem to be holding up to the amount of use that they get

the 8mm shaft motors make sense if your cutting balsa because of the higher KV choices

I maintain there's a tidy little sideliness/embryonic business for someone
i did mull the idea for a spell as i belive the larger brushless spindles would knock the knickers off a kress or even one of those posh water cooled chinese jobs at cutting ali and plastics (especialy so if your finishing with a fly cutter) but i get the feeling most people are after cutting wood on their cnc routers and stick to small tooling to cut the odd bit of alli so im not sure there would be a demand myself

From a quick search on tinternet it seems that most double row angular contact bearings seem to start at 10mm ID
yep! its a crying shame you cant get them smaller :cry: they work like a charm and make the job eeeeasy!!!
