Hello all,
I am new to the site, and new to machining. Being taught by a 1941 SB9C. The lathe has been 'restored' by a previous owner, who appears to have done a decent job. It came with the usual story 'sat in a corner, rarely used, etc.' As far as I can tell, it really does seem to be in pretty good shape. At any rate, I like it a lot. I can sit down across the shop and just -look- at it. I have a few questions (probably only a few hundred more will come later).
1. The spindle seems to turn very freely in the 'forward' direction, but if I manually spin it backward, it noticeably binds. I can turn it but it is sorta tight. Could that be the (possibly new as part of the restoration) wicks binding a little bit?
2. The oiler cups on the side of the headstock don't seem to take/use much oil. I only have maybe an hour or two of run time so far, but how fast 'should' the levels drop? Is there any way to -know- the oil is getting to the spindle bearings?
3. I have read various docs (http://www.wswells.com/data/howto/H-2.pdf) showing an 'automatic oil retaining valve' in the cone pulley (3 speed). When looking down into the hole under the screw, I can see something down in there, but I can't feel any movement when pushing on it with a narrow punch. Do they all have a valve? So I guess the question is again, how do I ensure I am getting oil in there?
Thanks for any help anybody can share on this.
