00:14 Jak_o_Shadows Hmmm
01:03 katsmeow-afk can anyone confirm a 60B13 is for #60 chain, and what that sprocket's OD is?
01:14 katsmeow-afk ok, a 60H14 is 3.75 D, so the 60B13 is a just lil smaller
01:34 rue_more katsmeow-afk, looks like there was a quake not too far from you
01:34 rue_more #60...
01:36 rue_more looks like #60 is 'big'
01:37 katsmeow-afk it is
01:37 katsmeow-afk pins are 2cm apart
01:37 katsmeow-afk good for ~ 1 ton of pull, iirc
01:38 katsmeow-afk not sure if i put a full ton on it that i won't twist off the 1.25 shaft
01:38 rue_more http://www.powerdrive.com/Downloads/ECatalogs/Sprocket/NO_60_34_pitch.pdf
01:38 rue_more oh the 60B(14) is the tooth count
01:39 rue_more so its 14 teeth
01:39 katsmeow-afk the 13 tooth will just fit on a HF winch shaft
01:39 rue_more 60 is the pitch... which is 3/4
01:39 rue_more B means it has a hub that sticks out
01:40 rue_more so its a #60 with 14 teeth that has a stickie-outie hub
01:40 rue_more I mixed it all up didn't I?
01:40 katsmeow-afk yeas, but the url was great!
01:41 rue_more ok :)
01:41 rue_more H is a 2 part hub...
01:42 rue_more well I'll write that down as a point for me, I dont get them often these days
01:42 katsmeow-afk but the browning H6013 isn't 2-part?
01:43 rue_more its not a welding rod?
01:43 katsmeow-afk no, that's e6013
01:43 rue_more oh, silly me!

04:19 rue_more I was up 3d printing inserts for the bandsaw table
04:20 rue_more I'm falling asleep fast tho

23:34 rue_more didn't read much
23:36 katsmeow-afk weld a bike sprocket to a nut, do =====bearingnutbearing===== , and bike chain to the bike sprocket, and you have the same thing, and you canuse Tom's modified starter motors to spin it
23:36 katsmeow-afk use some 1" acme rod, and you have some serious pull/push
