Nice little hobby machine, but for thousand bucks, a T-slot should be STANDARD on the compound slide for quick tool post. Please re-design.
I purchased this machine originally back in May, but it arrived damaged so I refused delivery and Grizzly sent me another one. Since then, I have experimented with the machine and found that it has tight tolerances, which is a great thing. The end gears NOT being nylon was an awesome upgrade. I recently installed a QCTP because I got really tired at having to shim up the cutters - something which should come included. Also, the cross slide/boss problem is an issue, but not insurmountable. I am overall pleased with the presentation and usefulness of the tool and have (since June) put it to use on several house projects (we own a completely custom home so nothing is standard) that without it, I would be at a loss. I think that lathes are, in general, the grandfather of all machine tools and for any DIYer, essential.
The variable speed capability is a huge deal for me, and one that really pushed this model over the top. Overall, I am pleased with the machine.
Recently purchased because of the size. I'm a retired tool and die maker that wanted a "hobby" lathe. I'm very surprised at the feed cuts I'm able to take. I was concerned with it being only a 3/4 hp motor. It takes them with ease (steel and hard steel). You can lock the carrage for face cuts by putting the carrage direction in netural and engageing the carrage feed lever(to lock the half nuts). The dial measurements are very accurate (checked with dial indicator). I came well packed by ups freight. Make sure you do the bearing run-in (see owners manual-set up instructions) to save your self headaches in the future. This is a VERY WELL made machine, I'm VERY IMPRESSED with it. HIGHLY RECOMENDED !!!!!
There are a few non-obvious things about this lathe. You can move one of the belts to change the spindle speed between high and low ranges- I was thinking that this would be better than the plastic gear used on mini-lathes (which tends to break). However this belt change is not easy. You need to remove the side panel to access the belt and adjust a set-screw, OK. But very annoyingly, you must also remove the back panel with the circuit board on it to loosen a nut which holds a belt pulley in place. This is not an easy or quick operation. I was thinking that the low belt position would be good to increase torque at low spindle speeds, but there is a label which says that you should not run the motor at high speed for long and suggests to leave the belt in the high speed position.\r\n\r\nOthers have pointed out the weak design of the compound rest locking screws, but there is more: notice that the compound hand-wheel has two handles, preventing quick single-handed rotation. This is because the compound leadscrew has no proper bearings (just a hole in thin metal) and the mating threads are right in the steel of the sliding part of the compound. There is enough play that the handwheel binds if you try to rotate it single handed. The cross slide design is better (there is a long hole to keep the leadscrew straight, and brass threads set up to be deformed slightly from a set-screw for backlash compensation). I think the smaller mini-lathes also now have a better design- notice that many of them have a chrome hand-crank for the compound.\r\n\r\nLike most mini-lathes, the cross slide and compound wheels are marked as 40 mils per rotation, but it uses metric lead-screws, so this it's really 39.37 mils per rotation. I don't think this is a big deal, but think it would be better to mark the wheel in .025 mm increments to match the screw.\r\n\r\nThe main carriage wheel moves the carriage one inch per rotation (I mention this because it's not documented).\r\n\r\nA minor point is that it is all too easy to crash the carriage into some sheet-metal covering the motor. The issue is that during work you are focused on the tool post, chuck and front of the lathe, so it is not so obvious that this interference exists in the back. You should put some tape on the bed to mark this position in the front.\r\n\r\nWhen you buy a chuck for the tailstock, get a normal MT#2 arbor, not a short one made for mini-lathes. The arbor needs to be long enough to be ejected by the tailstock wheel.\r\n\r\nI bought this lathe because it's a step up from the mini-lathe, and Grizzly makes it a good value with the included four-jaw chuck, face plate and rests. It's nice that this lathe can easily make reverse threads with the reversing gear-box on the front. This lathe seems to be a version of the VM210V lathe, which now has a version with brushless motor (eliminating the high/low belt speeds) but also sadly without the reverse thread gear-box. I want the brushless motor and the gearbox :-)\r\n\r\nAnother good point is that the brushed motor of the G0768 is very quiet (from what I can tell it's quieter than the SC4 brushless).\r\n
I pulled the trigger when it went on sale for $950 plus shipping. \r\nShipping crate showed damage, but not in area that might affect the product. \r\nUnpacked, cleaned off the wax/grease shipping protective material, and de-burred gib edges and lapped the machined surfaces with wet/dry paper on a sheet of glass. \r\nFirst project was to mount an AXA QCTP onto the compound without altering the boss or the M10x1.5 stud. \r\n\r\n https://www.youtube.com/watch?v=Etp0ezJN0iM \r\n\r\nCertainly would like to own a larger heavier unit, but the G0768 fits my work space, and my level of expertise at the present time. \r\nuTube videos are very helpful in starting out.
