Bill just watch out for the white papers as they have clay in them that tends to make them slippery, especially under pressure. Brown paper bag does not have clay in it and is stickier than the white paper.

That's the best explanation on using brown paper, thanks. Bob

There are many white papers that are not coated. Uncoated stocks are classified as bonds, offsets, card, newsprint etc.
Coated paper usually has a glossy, smooth or satin sheen. You can recognize coated paper that is printed because the ink is usually shiny because it doesn't absorb into the paper fibers.

Brown paper bags are made of craft paper. There are white bags made of white craft papers. Index card stock, paper from scratch pads, spiral note books and drawing and writing papers are rarely coated. It isn't the clay that makes paper white, it is bleach.

I thought I was the only guy using a ratchet at work I used a 1/2 ratchet with a 3/4 adapter a lot easier than using that darn chuck handle when cranking the jaws. We had a huge Aloris tool post which we built a girdle around two sides to keep it from slipping this was after management decided we should take a heaver cut to save time, went from a 0.05 depth of cut to .075 and more RPM. Amazingly insert life dropped so much it just wasn't any faster. This was in a supposedly annealed steel casting.

The jaws on my chuck are pretty tight. Turning them in and out can be a chore.
I started looking around the shop for something to make a crank handle. I measured the chuck wrench and discovered it is 3/8"

If you chuck is that tight I would take it apart, clean it good, take a finishing stone to any burs or tight spots and reassemble with it well oiled.

Big Rack, my old G-4000's 4" chuck was somewhere between 1/4 and 3/8 key size. So, it wasn't an option for it, or for my mini-lathe.

Jay, they aren't so tight that I can't remove and replace them with my fingers. Just a little stiff to freely turn with the t-wrench. I could spin them off with a finger on my G-4000.

Before I start grinding things, I'll give them some time and use to see if they'll loosen up some. I'm not sure tight chuck jaws are a bad thing.

Well I ended up in this thread trying to find out why my powerfeed wasn't working. I just got the same lathe a couple of days ago, I assume from the same shipment. I am including a photo of my less than glorious installation. It sits a bit higher than I normally see lathes but it seems comfortable enough.



The drip pan did not work for me because the countertop that the lathe sits on is fairly wide. That means the pan perimeter would sit on the countertop and the middle would get pushed in. Not planning to flood coolant, so it's all good.

I need to make some minor electrical adjustments (gfi keeps tripping on anything other than lowest speed and no load) and then I should put it to good use.

cheers,

Most VFD will cause that to happen. The only real solution is to get rid of the GFCI.

The 1127VF has a DC motor/DC motor controller, but an AC powered DC motor controller in many ways acts like a VFD (it has at least half of the same circuits), so I am not be surprised that it is giving the same false GFCI trips.

Cosmin, did you figure out how to make the power feed work? You have to pull on the handle before it will move to engage the power feed. That isn't mentioned in the manual. Sometimes you have to jiggle the gear change knobs to engage the gears so the hex rod and screw turns.

I think your stand is going to be fine. (I like the cribbing) I not sure I understand why the chip pan wouldn't work.
If you can find a restaurant supply, you can get a full sheet baking pan that makes a pretty good drip pan. They are 18" x 28". I gave about $10 for one a Ace Mart Restaurant supply. They are available on Amazon for about $15.

Powerfeed eventually worked, glad it did. I was already evaluating what it would take to get the lathe off the stand and potentially send it back, and I really hated that scenario.

The chip pan has a margin that sits lower than the middle of the pan. Once you set it on the bench, there is about 5/8" gap between benchtop and bottom of the pan. The weight of the lathe would flex some of that, but I didn't think it would make for a nice flat surface. If it helps visualize, take a framed photo and put it face down on a table. You put something heavy in the middle, it'll crush it.

On an unrelated matter, my lathe came with oil in the gearbox, perhaps a little too much of it. Not sure that's a good thing so I just changed it and only added to halfway of the sight glass.

cheers,
Cosmin

Ok, I get it. You'd need to put a sheet of 3/4 plywood under the chip pan, which would raise the lathe up even higher.
I recommend the baking pan. If nothing else, it makes cleaning chips much easier. I put one inside my chip pan. It's a lot easier to just pull the pan out and gather up chips than have to scoop them out from under everything.

Once you make some chips, let me know what you think.
