2019-05-27 16:19:51 +0000 UTCI saw the words "spindle" and "teardown" and thoguht you took apart the fancy one that youbought.. alas, then I saw "China"....sigh. On the uphand. In the background, I spy with my eye something begining with Advantest perhaps? Can't make out the make or what it might be.. hope you can share soon enough :D

2019-05-27 16:03:11 +0000 UTCthere are air-cooled units as well, but liquid is theoretically nicer for all the reasons it's used in PCs as well

2019-05-27 13:18:44 +0000 UTCwhy does that thing need to be water cooled , but not my woodworking router?

2019-05-27 13:11:52 +0000 UTCGuilty. I ran it without coolant for a few seconds yesterday, not expecting it to get that hot that quickly

2019-05-27 12:06:44 +0000 UTCInteresting teardown. Was the spindle over heating caused by you or someone else?
