New to me 1929 wide (heavy?) 9" long bed and overhead silent drive casting trade

[mattthemuppet]

thanks, I like my lathe too, though I think I'll like my new SB9 alot more

got the ID threads cut and through hole drilled last night....

[mattthemuppet]

slitting saws are a pain in the azz. As long as you accept that it will take forever, be miserable and look like $h!t at the end you'll be fine

[mattthemuppet]

I'll see how much space I have for a rear drive vs. overhead. The space behind a lathe is kind of dead, whereas having a motor and mount a foot and a...

[mattthemuppet]

dang, that's beefy. The South Bend catalog made the pitch that it was a turn key lathe package that occupied the same space as a line shaft machine and...

[mattthemuppet]

congrats, that's a fun find! I need to make up a countershaft for an SB9 I just bought and I'll be using a treadmill motor too, so it'll be interesting...

[mattthemuppet]

good score! I've always read to use as little and as thin an oil as possible, these things are pretty sensitive to friction and the like. I've had a 0.001...

[mattthemuppet]

alright, I discovered something today - that I'm an idiot.

Why was my carbide or HSS threading tool not cutting, when running the lathe in...

[mattthemuppet]

oh, and here's the catalog for that year - pretty sure mine's the one on p.22

Tim, it was from http://www.lathes.co.uk/southbend9inchjunior/, there's no accreditation on the page though. I spent a bunch of time trying to figure...

[mattthemuppet]

could well be reggie, I'm not an expert, but I think that they also came like that from the factory too. Here's what one looks like complete:

hi all,

I came across this SB wide 9 project a while ago while helping a "new to lathe work" guy set up his Clausing and last week...

[mattthemuppet]

dang. Just dang.

[mattthemuppet]

you don't have Cree LEDs in that light, I can guarantee you of that. If it makes you happy to think you got a 2000lm 10W light for $5 knock yourself out,...

[mattthemuppet]

then something that you measured is wrong - either the layout or the current per string. If they're being driven at 105mA per string of 15 LEDs (3 series,...

[mattthemuppet]

electro (or chemically) polished alu hard anodised would be very smooth and durable. A good anodiser (or lots of trial and error) will get you a very...

[mattthemuppet]

not that I've ever noticed - even with some bad chatter from trying a 3" long side cut with a 1/2" end mill didn't make any difference.

[mattthemuppet]

to be honest, with cheap Chinese LED lights of any variety actual output is typically about 1/4 to 1/3 of what's claimed. So I wouldn't go off any number...

[mattthemuppet]

to be honest LED bulbs that have that many LEDs are typically mains voltage rectified to DC with a simple diode bridge and a resistor (or resistors in...

[mattthemuppet]

that's a beautiful Litespeed - I lusted over their mtbs back in the day.

As for worries about stuff breaking - read what I wrote earlier....

[mattthemuppet]

yeah Chinese ER collets are kinda crappy. One day I'll save all my pennies and buy a set of Tecknics at least. I already have $2.50 saved up, so won't...
