10X18 lathe. Lots of potential in this lathe, but for the price you're paying don't excpect gibs or dovetails to be ground, lapped or scraped flat.
Luckily I'm prepared to do just that: -Hand scraping everything that needs to be scraped, and my lathe really needs some work.
The gib for the compound rest looked like it had been machined with a lawnmover and only makes contact on the ends of the gib. No wonder the lathe is prone to chattering unless the compound is tightened down hard.

The top of the compound is even worse. Not exactly flat.
You buy one of these and six months later you buy another brand costing a bit more in the hope of fixing your problems.
And so it goes until you end up with a 100 grand pro lathe . . . unless you fix your first lathe by doing some scraping,-which is what I intend to do.

These machines are made to such a low price point they nearly always require some finishing. Some elbow grease can work wonders

The lathe is a quite heavy and robust machine, a different beast compared to the small mini lathes you can get from places like HF.
By locking the compound down hard, locking the cross slide while turning along an axis and the saddle while facing I can really dig in to the workpiece with no problems. This tells me that the problem is adjustment and or scraping of the gibs that are needed. Fine tuning the gibs by using the screws won't help much without making sure that the gibs make good contact. -Already done that, so elbow grease it is.
