a good tip on putting the chuck om, bring your tailstock to the chuck and pet it press lightly against the chuck while tightening the chuck mounting bolts. It will hold it til everything is tight and keep it square.

Have you looked in the bottom of your headstock? I did all the specified oil changes and break ins when I got my G4003G new in '16 and since but did not look in the bottom until yesterday. There is not that much time on my machine as the past three years I have been occupied building my large shop addition by myself. Anyway when I drained it I thought I would check the bottom for metal wear.and was I surprised! I had seen another KZfaq recently where the cross slide was full of machining waste. Well you guessed it my lathe looked like solid sparkles on the bottom. You have to mop it up out of there as the brilliant design put the drain plug (which is also designed to dump all over the back of the headstock!!) up about a half inch and there is no slope in the casting to channel it to the drain. So all that metal from day one stays in the headstock as it goes to the very bottom and a simple oil change will not get rid of it. I poured several gallons of diesel in there and use a paint brush to swish it up as it was draining. Then rags to mop it all out. Grizzly just doesn't want to fight the crappy chinese quality control I guess. How much does it take to clean the machined parts before assembling them?? It is outrageous that the design doesn't even allow the crap left in to be drained out. They also used the cheapest of heavy orange/red paint that will dissolve in any good solvent. Brake Clean immediately started dissolving it. The most rudimentary of assembly skills seems to be totally lacking in the Chinese but they are always like that and importers promise quality control of their own in the factories yet that seems not to be true. Bearing are not going to last long under heavy use with that swarf left in the machine. It doesn't seem to matter whether you buy a 'Brand" name or the cheapest of imports they all come this way from what I have seen from owners on KZfaq. Seems there must be a Chinese law mandating crappy products and sabotage for exports?? I have to put the load on the big importers as they can specify the design and quality control before bringing them to market here in the States. Grizzly for one seems to have grown so fast and reaped such profit that they have left all their old quality control and customer service behind. They like Jet were at one time a source of quality cheap machines for the little guy to start with or the home shopper. Bottom line: Any more I would seriously advise a total machine clean up in detail before ever applying the power to any import tool. If there is a choice at the price point stay away from the Chinese!

I’ll share a recent experience with my G4003 gunsmith lathe. It recently locked up on me while in use. We trouble shot the issue and found that the input shaft on the quick change gearbox locked up and also sheared the key on the 16/32 tooth combination gear. Ultimately the problem was caused by inadequate lubrication, which i routinely do on this and all machines. The problem is that if you think a squirt or two of oil in the tagged oil holes on the gearbox itself are enough, it just isn’t true. Those holes lead to a tray that is cast into the top of the gearbox housing. Inside this tray are additional lube holes that eventually make their way downward to the rotating gears and shafts inside the gearbox. Blah, blah, blah, but the moral of the story is when lubricating your machine, squirt at least 2 to 3 ounces of lube in this section of the machine to fill that tray. If you don’t see any dripping from the selector shafts into the chip pan, you likely don’t have enough oil in there. Good luck.

I bought the G0720 Heavy Bench mill when they moved out of PA. $3000.00+ mill, in 9/15, used maybe eight hours in that time frame, milled aluminum only. I now get a ERR message when I try to run the drill motor...they now want almost $400.00 for a new controlo board that must install. NO more Grizzly for me.

Shane, looks like a nice little shop. Still Love to Play around in my shop. A couple things to watch out for, the strings off of your pieces try not to grab with your hands. They are sharp and will catch sometimes and cut you. Also the chuck key, get in the habit of always removing it. Enjoy your Tools.

watching your video I had the same problem you have with the cross slide handle dropping down changing the setting. if you have the manual it is part number 530a that needs to be tightened.

Safety glasses?? I can't show this to my students. Or maybe I should for that reason.

Thanks for the vid. You may have sold me on spending the extra $ instead of a smaller lathe like the 752. Was wondering how long term they held up. You seem to use yours more than I initially would be.

which mechanism causes the spindle to stop very quickly at high speed without applying the brake. thank you

What did you lift your lathe with? Engine hoist? Fork lift ?

WOW! America makes an oil can, I can't believe it.

When is the last time you cleaned the chips out of that chip tray?

I have a question. (I have the same lathe) Have you figured out how to not speed up the feed rate when making RPM changes. In other words at a high Rpm the feed rate is way to fast.

never leave chuck key in chuck
