Oddbean new post about login | logout @woodland creature :pleroma_fox_tan: could use a sacrificial bamboo knitting needle
@67975218 yea, i just wanted to test the idea. holding the rings securely while cutting, and using a thinner disc ( i do have some much thinner ones, i just used what i had handy), and annealing would all make it come out rounder i think
@woodland creature :pleroma_fox_tan: it definitely turned out better than i expected with the 1mm disc. i might try the dremel route and just get the thinnest discs i can find :blobcat: google really wants me to look at aliexpress cutting discs. im not sure thats a good idea
@67975218 thinnest abrasive discs i have are 0.6mm. no fiber reinforcement tho so they will shatter. i wear a face shield when using https://fluf.club/media/e06b2cf1229f280543f9c43269b2fd13a1c98fbef53a0c21af1fd5344768492c.jpg
@woodland creature :pleroma_fox_tan: do you need to lubricate the coil for this?
@woodland creature :pleroma_fox_tan: this wheel seems better right? https://www.dremel.com/us/en/p/ez409-2615e409ac its a .6mm fibre reinforced wheel they dont sell it here i would have to order the mandrel and wheels from overseas
@67975218 ya those would be good. we have them at the hardware store i think. that's a proprietary system with their dremel arbor though. whereas you can get some cheap ones from ali express with just a hole and generic arbor they're not that dangerous, so if they shatter it might hurt a little- but this is why i wear eye protection plus face shield and gloves, and an apron, and and generally have no probs
@woodland creature :pleroma_fox_tan: is the dremel necessary. can i mount the arbor on a drill, or is that a bad idea
@67975218 dremel spins at about 20k rpm. a drill maybe 2k. yes you could try to use a drill but it might be slow and not work that well
@woodland creature :pleroma_fox_tan: ok ty, i think a dremel is better then
@67975218 this should work. would make smoke though.
