This is by far the best video on this particular lathe I have seen on KZfaq. It solidified my decision to purchase one. I am an amateur to metal lathes but have 2 good friends that have operated them at a professional level. Thank you for posting this great video. It is extremely informative and I look forward to seeing some more videos with milling being done.

I watched this video to get more information on this particular lathe. Then I checked out the Maker Barn on Google. Then I discovered the Maker Space and discovered there is one near me. I went to check it out and it turns out they have the same Grizzly lathe as well as a bunch of other equipment. I am becoming a member because it is a heck of a deal to get use of that equipment for a bargain price - as well as the community it supports. It is AWESOME!

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

Thanks for sharing what can and does happen when someone is "grabbed" by moving machinery. Several years ago I took a machine shop class at a community college. The teacher cautioned us to never do dumb stuff, much the same list you covered. He told of an incident that happened some time before then in which a fellow with long hair was a student and the inevitable happened. His hair was caught in the spinning chuck and he was scalped immediately. The teacher didn't say - and we didn't ask - whether the student survived or not, something best left to the imagination. That single incident was why they added shutdown stations, located about every 20' along all the walls to kill the entire shop machinery. Although Murphy has probably been gone for quite a while, he still rules when it comes to chance.

The lathe has been doing well, no complaints. The only thing I miss is that the feed lever uses positive engagement rather than a clutch. I think this is normal in the small import lathes. The larger import lathes do use clutches to control feeds.

Nice looking lathe & especially nice looking DRO. Thanks for your comments on my video. I now have the radius/diameter working correctly using the 1/2 button instead of changing the resolution. I also mimicked the font & yellow color of the axis button and made Z button covers for the axis labeled Y - just more of my OCD kicking in. 😀 Enjoy your lathe!

There are a significant number of experienced lathe owners who believe it is a mistake to store tools in a place where you need to reach across the lathe to get them. Of course you would normally only reach across when the lathe is stopped but the temptation may be to reach across when it is running and that is an opportunity for disaster.

I have seen the caliper solution which is fine but many DROs offer the third function for very little extra putting all the info at one spot. Possibly could be used at the taper attachment.

I've had nothing but issues from one of their products. My wife and I drove over 5 hours, and spent over $1200 at the Grizzly showroom in Missouri. Honestly the showroom is amazing. The product I got...not so much. I've had over 10 separate issues including defective, and back ordered parts sent to me. Grizzly did offer me $100 to keep the pos 😂😂😂. I like high quality tools, and won't hesitate to spend the money on them. SCM, felder, festool, saw stop etc. I like decent hand tools such as snap on, Milwaukee, dewalt, and I even think husky is decent due to being able to swap tools easily when they break one the job. We even have some harbor freight tools that I think are very very good. My experience with grizzly has been unsatisfactory at best. Not to mention they will not post my review on their actual website. Hopefully my review will help someone looking for equipment.

I have had the G4003G which is a very similar model for several years now and am thinking of installing a DRO (I have that same model on my mill). So it would be helpful to see exactly where and how you installed the scales for yours as well as the sizes (metric) necessary. I am also wondering if a three axis DRO could be used to measure the quill travel on the tailstock as well? It would also be good to see you fine tune the compound and cross slide friction on the handwheels. Mine seem to loosen up a tad fairly quickly to where they may move a thou or two while machining if not held. Good subject matter for those of us who own that lathe. Take care. Doug

You can adapt & mount a caliper on the tailstock that will do the same thing. It will be just as accurate, much less expensive and easier to install.

Great video. Thanks. I have the same lathe and it's about 5 years old. I'm having a motor problem and I'm going to have to pull the motor off to figure out the issue. It's stuttering going into reverse and a little bit in forward. I've checked everything and it's definitely the motor. It's either the capacitors or centrifugal switch. Also could be a winding. Have you ever had an issue like that with yours or one like it?

Not with the 4003, but a Grizzly planer has gone through a couple of start caps. There is probably a start cap and a run cap. The run cap is the smaller value. The start cap may have blown its seal.

(BTDT) btw, my 12x36 is a HFT and decades old. Most Grizzly parts work just fine when/as needed, esp the two electrical bits I replaced. IMO it says much about the design that it hasn't needed to be changed or upgraded. Make chips, Boys! 😁

@@makerspace533 All a matter of what you're willing to spend and how much time you want to spend rebuilding a worn out machine vs making parts. At the price point of this machine you will not usually find old American Iron that's not well loved and in need of major repairs. I can admire the beauty of a restored 60 or 70 year old lathe but learning to hand scrape a badly worn lathe is not something I want to do. It takes a long tome to rebuild one and no parts are getting made when you're repairing the machine. Waiting for a good deal on one that's not beat to death doesn't get parts made either and it's still going to need work. I'd rather do some cleaning and setup and get on with making parts. Yes. It's not a work of art. Not my goal.

I have this rebadged Taiwanese lathe also, but alas I don't get the bling DRO attachments useless when you retool or change something - as for the cross slide gibs a machinist needs to have access to and adjust then remove and clean more than occasionally - how do you with this next to useless cluttering feature bolted ?. What about your compound and your tailstock - no DRO's - what's the point ? seems like old school masters just die out and nice new toys with lots of bling sit about collecting dust with no real machinist work. The age of snowflakes.

One might have to use DROs to appreciate them. No more backlash for one thing. My compound is usually locked down. Does a tailstock used for drilling need precision depth? Not really. For turning steps to dimension, locating grooves, or parting the long' feed is more than handy. Nothing there for threading? With this lathe it's prudent to leave the half-nut engaged, and precisely backing out and returning the cross slide for next pass gets easier. It's only bling if you think you need it. I don't, but still have it on two machines and newer versions aren't pricey anymore. Cheers.

@@makerspace533 Oh, you're quite welcome! I'm glad I made your day a little brighter, but "moronic?" I'm not the one with the bad grammar. Maybe my standards are higher than what you're used to, but then again my machining buddies work @ JPL & Northrop. So I'm used to people that know how to machine parts to space-tolerance AND can talk more gooder then ewe. Then there's your hippie. Again, *not* rocket science to wear work-appropriate clothing. A lathe can rip your arm off. It can turn a piece of work into a projectile with sufficient velocity to kill the operator and standers-by. The jet story is both funny & true. The whole lookie-loo thing is a personal pet peeve. Traffic where you live may be virtually non-existent, but here it is wrist-slittingly bad. AND THEN you've got the dummies that don't realize 2 metric tons traveling at 100 k/h (you know, the whole force=mass*acceleration thing) is more than sufficient to destroy the cars occupants. I work with power tools, I don't need to be reminded metal can hurt, but they still INSIST on looking and slowing me, & a thousand other travelers, down. So, no, I don't post gratuitous videos of people being harmed as "reminders." If someone needs reminding of this sort they shouldn't be working with power tools. ALL THAT SAID, I'm glad you folks are taking a safety first position, because there's as lot of dumb kids out there with a monkey-see, monkey-do genetic marker AND plenty of you-tubers posting videos of themselves doing dangerous &/or stupid things. I take them to task far worse than I took you because I think of those monkeys/kids lopping off a body part they might need in the future. Cheers! ;-)
