Oddbean new post about login | logout @67975218 hi, yes it will spark. no lube needed. any grease or oil or paint on the metal will just burn off when you cut it. you'll see the metal does get very hot (melts in fact right at the cutting surface)
@woodland creature :pleroma_fox_tan: man am i gonna burn my house down doing this :monkas:
@67975218 dont worry too much about that. just don't send a shower of sparks onto your carpet or anything highly flammable like open containers of gasoline, piles of dust, etc. it will burn clothes. i wear a cotton apron when grinding. it's a good to set up a work area. if you have a garage or anywhere with a concrete floor that is preferable. the sparks and flying metal will damage stuff
@woodland creature :pleroma_fox_tan: i set up a space in a storage room thats isolated from furniture and stuff but still wooden floors and bench. if it's not good enough i will ask my neighbour to use his garage. thanks for answering my questions :blobCatFriendly:
@67975218 storage space is ok but you will find the fumes are gross. i would wear an N95 respirator. the abrasive wheels are bonded rubber, fiberglass, and aluminum oxide (or other abrasive) so the rubber burns, dust and fine metal and fiberglass particles become airborne. you def want a mask for that and ventilation. it's not going to kill you immediately but it's best not to breathe it
@67975218 ps you can use a diamond wheel if you want to cut down on harmful dust and rubber fumes
@woodland creature :pleroma_fox_tan: i thought those were for using on stone
@67975218 diamond will cut anything. the only thing idk about is aluminum- it may gum up the wheel. you'd have to try it out. diamond can cut steel though. certain abrasives work best on different materials- AlO2 (the black ones) are good for steel. aluminum gums them up
@woodland creature :pleroma_fox_tan: ok ty, ill try it
@woodland creature :pleroma_fox_tan: oh 1 more question, do you wanna move it along the coil in the same direction that its spinning or the opposite or does it not matter
@67975218 what you're talking about is "climb" vs "conventional" cutting direction. for hand held tools you generally want to use conventional cutting. meaning, you're pushing against the direction of force rather than with it. reason being a "climb" cut has a tendency to get away from you by climbing onto the work
@woodland creature :pleroma_fox_tan: that makes sense. thanks
@67975218 @woodland creature :pleroma_fox_tan: Not if you swear allegiance to the lords of the fire realm first they will protect you
@Powerlinx Kacho @woodland creature :pleroma_fox_tan: i will make an offering :pblobnwn:
