This doesn't matter, really. If I hadn't thrown that plastic protractor in the garbage soon after I got my lathe, I could take some pictures of my 7x lathe compound for you.
That is a gap between the (metal in my case) protractor and the cross slide. Gib seems to be well adjusted and I have no play in there. Protractor does seem to be not very precise.Here (blue lines).

You also can see the same gap if you hover the mouse over the product image shown here.
For comparison, take a look at the Grizzly 8 x 16 shown here.
Got it, thanks. Sometimes a picture is NOT worth a thousand words....This doesn't matter, really. If I hadn't thrown that plastic protractor in the garbage soon after I got my lathe, I could take some pictures of my 7x lathe compound for you.
The gap you are showing is the gap between the plastic protractor and the cross slide. The metal part of the compound screws down tight to the cross slide with two socket head screws. There is no gap.
If you are looking for potential looseness, the gib adjustments on the cross slide and compound are the places to check. Lots of users remove the 7x compound and replace it with a metal block (aka 'plinth') to eliminate one set of movable connections.
I find it really difficult to take pictures to 'make a point' about how things really look. Either the camera won't focus on what I want or the angle or lighting is wrong, etc.. I often get fooled looking at other peoples' pictures, too.Got it, thanks. Sometimes a picture is NOT worth a thousand words....
Seems everyone has issues finding direct bolt on 4 jaw chucks for these.You might be out of luck on the low speed adjustment- see if there are any trimmers on the circuit board
but mark them with a sharpie before tweaking any so you can go back where you started
None of these mini lathes have much documentation for the speed controls- if they fail the only options
are replacing a board or retrofitting a different motor and controller
There is a place that repairs some of them:

or drill 3 holes in the 4 jaw ands thread if the registration matches.For the chuck you probably have a 3 hole bolt on now, and will find most 4 jaw will be 4 bolt.
So adapter plates are needed.
LMS could be your best bet.

Most likely same issue you will have.
I had a Vevor 7x (not the same lathe) with a 100mm spindle flange, and it had holes to match both 3- and 4-bolt chucks. So the OP might get lucky with that. Otherwise, modifying the chuck to a 3 bolt or using an adapter plate, as mentioned by @mac1911 and @dabear3428 will be the solutions. Matching the chuck recess to the boss on the flange is usually the problem if 'moving up' in chuck size.For the chuck you probably have a 3 hole bolt on now, and will find most 4 jaw will be 4 bolt.
