Congrats on your new HF7X10, I'm sure you are going to love it. To really make it more user friendly, when you can, find or look for a QCTP (quick change tool post) It can make changing tools and going from a facing tool to a boring bar, or cut off, so much less complicated and for the most part it can help you find the very center of the work piece. No more fumbling with Allen head bolts and trying to realign the tool post that comes with the machine as sold.
The QCTP can be found at sites like The Little Machine shop, and you can order one from A-Z for about $100.00. This will allow you to have 4 quick change tools already mounted and it takes only seconds to go from one operation to the next. Most kits include 2 cutter modules, and a cut off and boring bar holder. all of them are made adjustable to raise and lower to find a quick center or to compensate for a larger or small size cutting tool. I think it will fit anything form 1/4" to 1/2" cutters, without using shims.
The next and also very important thing is have good lighting, that you can direct on the work.
After you have used it a little you will see the limitations of the 3" chuck that comes with it as sold, and you may be tempted to buy a bigger chuck, be sure to look into a 4 jaw chuck instead of the self centering 3 jaw type, with a 4 jaw you can hold odd shapes and square stock that you could never hold with a 3 jaw. I prefer a chuck that each jaw is adjusted individually, with a little practice and a dial indicator it becomes 2nd nature and only takes minutes to do, allowing you to even mount and turn rectangular, and offset material, (think crankshaft) if that is what you want to do. You will be amazed how much more material handling, you can do with just going to a 4" chuck, and anything bigger then that will probably be too heavy for this little machine.
Remember that this is a mini lathe, and as such it cannot hog off deep heavy cuts in most any material, trying to cut too much material at a time is the quickest way to destroy the gear train, and smoke the little motor.
Protect your eyes and keep the chips out of the gears under the saddle, keep the ways clean and well oiled and the regular use of a chip brush, an air blowgun or vacuum, and keeping the gibs adjusted and you will have years of fun with this great little machine. I think the 7X10, is probably the best bang for your buck of any Powertool made, 90 pounds of dynamite.
ENJOY
