After setting it up and cleaning/lubing everything, I put hte small lathe thru it's paces. I find with a newly ground bit (5/16 HSS), you're not going to take heavy cuts. .020 on softer materials is probably the most youd do. there is a bit of flexiness to the compound, but if you work with aluminum, brass, plastic or wood, it's fine. It runs quiet and your cut will make more noise than the machine itself.\r\nI do not like the accuracy of the dials. make sure to verify your depth with a vernier or mic. Traverse across the bed is true to .0001 perpendicular. also verify your compound squareness to the work. I don't trust the angle indicator either. using 5/16" tool bits, you need to shim them to center height\r\nproperly set up and lubed, this machine will give you 1000's of hours of happy machining. recommended you upgrade to a QC toolpost (0XA), and 4 jaw chuck
Everything works like it should needed to do the cleanup and no big deal
To start with, it is a pretty awful lathe. It certainly isn't built to last, and it most definitely could have been better. A lot better. However,lets look at a different lathe. The Myford Super 7 has been a standard of quality for some time now. It's an excellent lathe, with lots of parts and attachments and tooling available. With The Grizzly 7 x 12, lathe, it + basic attachments and tooling will probably end up costing you around $1,000- 1,200. Compare that to the Myford's $10,000-12,000.\r\n\r\nIf you buy the myford, who knows how much you will use it, or weather the attachments and tooling you buy will really be of any use to you. A Myford is not a beginner's lathe. It may be an excellent lathe with lots of bells and whistles, but it may not do what you need. \r\n\r\nThe grizzly 7 x 12 Is an excellent way to learn the basics and understand what you need and what you don't without spending some obscene amount of money in the process. This lathe is pretty much the bottom of the market for something of it's caliber, and it is no where near professional quality, but it will do the basics pretty well.\r\n\r\nBuy this lathe, run it into the ground, then get a real one.
This lathe is outstanding. Cuts like a dream with good carbide bits and holds good accuracy. Dials are in .001 increments and cut .0012. Close enough for government work. \r\nProblem is tge 4 jaw chuck that goes to this lathe has been discontinued. Seriously grizzly bring the 4 jaw chuck back.
Grizzly is known for high quality shop machinery, and this lathe is no exception. It has a relatively small footprint, but provides exceptional capability for its small size. I needed a bench top lathe for making small parts for model trains, and this unit is a perfect fit at a competitive price.
The G8688 7" x 12" Mini Metal Lathe was a good purchase for me. I'm new to metal working and have already broken a couple cutting tools and blown a fuse, but the machine was straight forward to setup and learn so I'm routinely producing parts with about 1 to 2 mil accuracy and expect to improve. The best part of the purchase was the Grizzly team! They went out of their way to make shipping and delivery a good experience for me. And, I had a technical issue just after purchase that they bent over backwards to make right. Excellent team!
