02:56 AM rue_bed: hmmm
11:10 AM rue_: ok, 3 rings
11:51 AM Tom_L: engagement, wedding, aniversary?
11:55 AM Tom_L: they got a ring for everything nowdays
12:11 PM ace4016: push ring
02:27 PM rue_: I got 3 peices bent for half the innermost 7.5' ring
02:27 PM rue_: but there is a problem
02:28 PM rue_: the main drive roller is moving somehow thats causing the chain to slack off under load and skip
02:28 PM zhanx: you need a way to connect them?
02:28 PM rue_: there are two drive rollers
02:29 PM rue_: one of them transfers the power to the other tho
02:29 PM rue_: I have to take it apart, what I'm seeing happen shouldn't be possable
02:30 PM rue_: unless one of the timing sprokets literally broke
02:45 PM weyland|yutani: rue_, maybe you need a tensioning roller so under load you chain dosnt slack
02:45 PM zhanx: that and to make it stronger
02:45 PM weyland|yutani: tripple chain :D
02:46 PM weyland|yutani: http://www.iwis.de/uploads/tx_sbdownloader/KettenHandbuch_E.pdf
02:48 PM zhanx: surpised that is in english, then I realized what the E was for
02:50 PM weyland|yutani: neat little book if you need some help getting our chaindrives to work
02:50 PM zhanx: i saved it
02:51 PM weyland|yutani: the part about shock load is maybe what rue is having a problem with
04:30 PM z64555: slack doesn't matter if its only going in one direction...
04:30 PM * z64555 has no idea whats going on
09:00 PM rue_: something is moving that shouldn't be
09:02 PM rue_: the roller and the sprocket are not staying in the same place, it shouldn't be possable for them not to stay togethor
09:02 PM rue_: so, I'll take it apart and see whats up
09:02 PM rue_: the sprocket was running eccentric
09:02 PM rue_: that alone should be impossable, the pin thru the sprocket is the same size as the sprocket hole
09:03 PM rue_: implying it broke
09:51 PM z64555: next question of course would be why did it break
09:52 PM rue_: I have to take it apart and see what happened
09:52 PM rue_: it wont be easy, the pin on that roller is "stuck"
09:53 PM rue_: it shoudl just slip out, it takes some work
