Here's a brass tubing center with bearing I machined at 600 rpms with carbide insert in the SB1001 for turning 6061 aluminum tube, no more oiling the dead center. I machined in a center relief so the bearing could spin free

The 8K out of the crate, lubed and after spindle break in is a useable machine. All controls, carriage, cross slide, and compound are smooth but rigid. 0 run out at 1" from face of spindle with a Miller test bar, .004" at twelve inches but that's without properly cleaning all surfaces. The D1-3 4" chuck is above average for a three jaw and the D1-3 5" with no adapter and reversible jaws is nothing short of incredibly precise. The only thing I find lacking with the 8K is not the lathe but the spindle adapter (4.5MT-3MT). I purchased one from Miller Machine to use with my Miller Machine test bar (3MT)

I posted these photos to see if there was any interest in the 8K which is on sale at this moment for a ridiculous price for a lathe of this caliber. If anyone has an interest I have much more info.

Hi Barry,

Grizzly Tools, a major importer of Asian tools, bought the South Bend name some time ago. They market a whole line of "South Bend" branded tools, lathes, mills and accessories.

The lathe reviewed here is this model:

http://www.grizzly.com/products/SB1001

IIRC this lathe is produced in Taiwan to higher standards than the Grizzly line of machine tools. See SB history here:

http://en.wikipedia.org/wiki/South_Bend_Lathe

As far as "ridiculous price" goes, well that has different meanings to different folks. It appears to be a well made machine and has the advantage in the US of good support from Grizzly.

Cheers,
Phil

Here are some random photos, Sale price is $1900. Spend a day with this machine or the new 10K and you'll know what quality is. The 8K comes with a two page test record signed and dated by the inspector and the director. My last lathe certainly didn't come with any such record. Reminds me of when I made high precision switches for NASA and the Armed Forces. Every step of production was signed and dated. Also the lathe was useable out of the crate! I only leveled the ways with a Starrett machinists level, lubed it and broke in the spindle. That test face on brass was perfectly flat, and the 16" aluminum turn had only .004" run out without touching the tailstock. I just don't see where you would get a lathe with hardened ways, D1-3 camlock spindle, 1-1/8" spindle bore, variable speed brushless 1.5 hp motor, digital tach and more for $1900.00 with any other lathe out there.

Here's lathe first set up with 4" D1-3 chuck, above average 3 jaw, since then I have the 5" D1-3 chuck which is exceptional and has bolt on jaws.

The spindle bore on your lathe is 1 1/8", which is larger than the 10k SB lathe version which is a definite plus.

Cheers,
Phil

And the variable speed, my 7X16 had that and once you've had V/S it would be hard to go back, specially since I have all carbide inserts except the cutoff which is HSS. One thing to note is the 4" chuck is smaller than 1-1/8", but the 5" is slightly bigger. 1.125 SP. to 1.126 CK.

I have to say the double t-nut slotted crosslide for the compound base on the South Bend 8K is a brilliant idea. I know it's not a new idea, just the same, my last lathe didn't have it and I spent a lot of wasted time trying to get the tool in the right position.
