Re: "tuning up" a mini lathe ¨C Apron Swarf Shield
I tried several alternative for an Apron SWarf Shield:
I firt tried the?:  This is held in place by Neodymium magnets, but is a little thick (and the magnets gather steel chips). Also, I'm not sure if they are still in business, even though their website is still up & running. I then tried the?:  While their current offering (above) looks like it is Aluminum, mine was thin plastic sheeting and I used a bead of Permatex to attach it to the Apron. This worked well, but the left edge tended to grab on my telescoping lead screw cover, so the last time I had the Apron off I made one from 0.010" brass, drilling & tapping the apron for M2-0.040 x 3mm screws (didn't use drive pins because I want to be able to get to things later):   The lower left corner is secured by the telescoping lead screw cover receiver which mounts using the M4 tapped holes (added when installing the cover).

Re: "tuning up" a mini lathe
I found early on a air gun is not your friend.??
It will blow chips every where like feed screws, bearing , gears, under bed ways and the list goes on.?
So air guns was band inside. They had to use a brush for cleaning . Had no more down time because of chips. The machinists had to goto welding and fab to use a air gun.
Today I use a shop vac

Yes. Good YouTubes. "Back in the day" we didn't really have those.
I ran across this one I liked which is fast paced and he has links in the description to more detailed ones for each mod. This one covers a lot of the common upgrades I have seen discussed for a decade or two. And he does a good job showing exactly what some of the problems look like, such as the tailstock not being quite parallel to the ways
I watch the video ?.? I took him years to do few fixes that finish in December.? The testing tail stock quill he did not lock quill for test. It only test in the lock position.?? The head stock bearing even after changing the bearing he still need to lub every 3 months.? The 6206 ball bearing comes in seal will last around 50,000 hours or longer. The others can last longer but no one labs and they open to air and over cleaning.? Dave?

I don't know if she was recommended here or not, but I've been watching the tutorials from "blondihacks".? She has a good pace (I do speed the videos up a bit) and is very clear on why she does everything, and why what she's teaching is important.? So far I've just been watching the beginner tutorial series, but I'm sure they're all good.??

And he does a good job showing exactly what some of the problems look like, such as the tailstock not being quite parallel to the ways.
But as has been mentioned a couple of times, many mods or accessories won't necessarily matter based on how your particular lathe performs as-is and what you are doing with it.
For example, changing to tapered roller bearings in the headstock is decidedly an improvement and documented in a number of places.? But I suspect only a small percentage of these things get that mod with most people getting results that are "good enough", at least for them.??
And some things, like a carriage lock, can just be purchased from Little Machine Shop or maybe others if you would rather.? Here is a link to it...
One I had forgotten about is the apron gear cover.? This is perhaps something you really SHOULD do and most everybody's lathe benefits from it.? Chips get into the gears very easily in that location and the cover prevents that.? In the video, he makes a metal cover.? I think many just make it from clear plastic.? Little Machine Shop has a cover that mounts with pins.? (I would change this and mount it with screws).? Here it is...
Alternatively, here is an apron gear cover on eBay.? Various people make some of the more commonly needed things like this and sell them on eBay.? So, it is sometimes worth looking there.
To pile on yet another source I think is good, check out "arceurotrade".? They have some nice documentation including how to take these things apart and put them back together.? Here is their page of articles...
Here is the arceurtotrade specific article for changing the headstock bearings to better ones.? This has lots of photos and will give you an idea of the nature of making this sort of an upgrade.
For things you can just buy or make, you have the classic "make or buy" decision.? That is not the same for each person or situation.? Some will tend to criticize anyone that buys when they could make.? But you can make your own decisions based on cost, desire, skill, whatever.? Your machine.? Your rules.
Speaking of skill, you will notice that quite a range of experience exists on this list.? But they all started at zero at some point.

I remember reading several years back that a guy I think he was
in England & when he unpacked his lathe there was a bag inside
with several brand labels that the seller was supposed to put on
the lathe before shipping . The only thing that my Enco doesn't
have that some of teh others is the lower rod for the power on
/off . I really wish I had that on my lathe .

Here's a blurb from Tony's site about import lathe , though it's
mostly about the larger ones it's still information .
??? I have? Enco 11x20 according to the part # in a tag on the lathe ,
but I have never been able to pin down a actual parts & owners manual
for it .
??? It's identical to all teh lathes here that have the square headstock .

Re: Grizzly is doing better - I hope!!!
I have one of the old Homier/Speedway models back from somewhere around 2000-2002.? I've not found any terrible flaws with it - even back then, there was enough info to sorta know what to expect and I've always thought it was well worth what I paid - when you really need a lathe, there aren't many good alternatives.? Maker spaces or online prototyping weren't a thing back then and machine shops didn't want to deal with the small bits I was machining.
Recently I've been making a few mods and bought some replacement parts from Grizzly.? I've found the Grizzly parts to be as good as and usually better than the original parts.? I've bought a few things from LMS and have been happy with them too, but Grizzly tends to be a lot cheaper and the quality is there in my experience.? Of course, if you order anything painted, it's going to come green, but their green paint is significantly better than the blue paint-approximating substance that colored my old lathe.
I'd hope Grizzly's machines are as good as their parts, but I can't say.? I think if I were going to buy today, I'd either buy the cheapest around, which is probably Harbor Freight, or I'd buy a Grizzly on the other extreme and pester them under warranty until I was satisfied.

I have disassembled and partially disassembled my mm 7x16 lathe at least 3 times. First two times was to make it operable. The first time was to basically clean it up. Why ? Because it would not move well at all and would stick and well, not useable.? Next time was to refine things, both cleaning, filing, better adjusting as i under stood more
There thing I do before run any lathe for no surprise.?? It like center when do center hole you quickly see it off. Simple fix with morse ream 5 minutes later it is right.? Jib adjustment will move as soon as move the lathe cross town? with a lot other nuts and bolts.? Dave?
