09:11 PM rue_mohr: I shouldn't be this tired
09:17 PM Tom_L: so in the near future i need to snake some RG-6 thru a 3/4" flex conduit that has 2 cat5 and 2 phone already in it
09:17 PM Tom_L: should be fun
09:29 PM rue_shop1: I suggest, if you can , disconnecting them, pulling them back with a string, and pulling all the stuff in at once
09:30 PM rue_shop1: for 3/4", with and bends and turns, 2 cat5 and a cat3 is basically full
09:30 PM rue_shop1: so I need to make another tank adapter

09:30 PM rue_shop1: just measuring it up
09:31 PM rue_shop1: imperial 16tpi
09:32 PM Tom_L: not possible to disconnect
09:32 PM Tom_L: i'll see if i can get a snake thru it first
09:32 PM rue_shop1: 27.5mm od material
09:50 PM rue_shop1: haha I dont have any suitable material
09:53 PM Tom_L: so ~ 1.25"
09:54 PM Tom_L: i've got an aluminum bar either 1.125 or 1.25 i forget
09:54 PM Tom_L: probably not the best material for that
09:57 PM Tom_L: 1" brass bar would be a bit small too
09:57 PM Tom_L: .080 under
09:57 PM Tom_L: .083
10:01 PM Tom_L: i've got some bronze plenty big enough but you're not gettin my bronze

10:13 PM rue_shop1: and a box like that
10:13 PM rue_shop1: you can punch them in with a credit card and nip the ends off with a knife

10:13 PM rue_shop1: I can make you a video if you want

10:14 PM rue_shop1: dont use my teeth
10:14 PM rue_shop1: (chipped one decided it wasn't worth it)
10:16 PM Tom_L: the coverplate i have will accept one of those for cable
10:16 PM Tom_L: this is RG-6 though not cat5
10:17 PM Tom_L: so yes, it needs a crimp end
10:17 PM Tom_L: i've got a box full of those cat5 ends though
10:19 PM Tom_L: and i've got the little punchdown tool for those
10:25 PM rue_mohr: oh sorry, I drifted, forgot it was rg6
10:26 PM rue_mohr: you can get F connectors for those modular plates
10:26 PM rue_mohr: "f bulkhead"
10:56 PM rue_shop1: hmm, I need a freq gen for this old z80 project
10:57 PM rue_shop1: I have this 74124
10:58 PM rue_shop1: oh, dual vco
10:59 PM rue_shop1: it wouldn't be stable tho
11:56 PM rue_shop1: som stupid-ass tiny cpld would probably do me fine
11:58 PM rue_shop1: there is no serial rom that will just output bits given a clock stream
11:59 PM rue_shop1: its too fast for a one-shot rc time
