I use this as a hobby and started off with a smaller one due to cost, which I regret. I've only had this lathe for a little over a month now but I'm quite impressed. It's surprisingly quiet compared to smaller lathes and extremely smooth. I can't wait to upgrade my mill now.
I am very pleased with this lathe. Have been impressed with cuts and threads made. So far my biggest issues are fit & finish. As long as buyer is aware this is not a production level machine, there are things it will and won't do. Right out of the box during break in the spindle engagement handle was out of adjustment. Pushing down on handle engaged forward spin, however the cam in the limit switch was way off and pushing down a little further would turn spindle off. Not good during a cut. Compound Slide bolts stripped almost immediately, Grizzly was great sending replacements same day. Also the splash panel interfered with carriage travel and had to be trimmed. If your a machinist be prepared to machine. I am pleased with this lathe and do recommend it. So far set up, leveling, turning has been straight forward. Get some touch up paint...
for a chinese lathe this is a great machine, lots of power and very accurate out of the box, took a little tuning of the gibs to get the cross slide and carriage to my liking.
the only complaint i have is the position of the tool post lever when locked, its pointing almost 90 degrees toward the center of the lathe over the work. this needs to be changed, also it would be nice to see lever on the carriage lock screw so you don't need to have a hex key to lock it.
I'm not a machinist, but I like to play one at home. Mine came extremely scratched and had various broken pieces. There was even a rats nest in the head of the lathe, but no vermin found in the packaging. I cleaned it all up and it seems to work great. Some one else noted that the stand is a piece of crap, I agree the stand is not great. The one I received has 1/4 steel base and does seem be very sturdy. I didn't install the middle piece of sheet metal as it had not apparent structural value and I can build my own cabinet there for storage. Overall, I'm happy with it.
A lot more lathe than I "should" ever need...but having room to grow is worthwhile. A couple of old school professional machinist friends stopped by to check it out and were very impressed with the quality of the machine. Their heads cocked to one side like a curious dog when I told them the relatively small amount I paid for it! I received a text from another friend asking for the part number so he can purchase one : - ) Oh.., and regarding accountability from the Grizzly Company, EXTREMELY satisfied! They go out of their way to ensure you are 100% satisfied, and I am!
Thus far I have about 8 hours using the lathe - mostly aluminum and some steel. Overall and thus far I am a satisfied customer. Pluses and minuses thus far:
+ Everything on the inventory list arrived in the box and all worked as intended right out of the box
+ Repeatability is good, accuracy is ok
+ Impressive circuitry and electrical box with obvious thought given to safety
- Paint is already coming off beyond original scuffing from shipping or assembly
- Setscrew on the motor drive pulley came loose after a few hours - disappointing as to assembly quality
I received this lathe as a Christmas present. Best present ever . I wanted it for mainly gunsmithing, in the past month I have spun up two barrels and the work is immaculate. If your on the edge stop thinking and buy this lathe.
I think this is an awesome machine I think it will serve my needs real well.
The lathe was shipped fast and I did not find any damage even though the crate was broken. The lathe seems to work fine but the underside of the ways were not machined properly nor cleaned after painting . Because that was not done properly it caused the tail stock to jam when I tried to slide it toward the head stock. I was able to clean up and repair that flaw and now it seems to work more smoothly. One thing I think would help is if the machine was shipped with oil in the gear box. Not having the oil shipped with the machine is a problem as sourcing the correct oil delays use of the new machine and also adds an additional unnecessary cost.
Vivo en El Salvador, y estoy muy feliz con la máquina, es un excelente equipo que ocupa poco espacio, la máquina es en verdad una " Pequeña Gigante".
Big improvement over my smaller older machine. I get the job done in half the time now. Loaded with extras. Money well spent.
The lathe arrived packaged well. No damage in shipping and all parts were included as per description. The lathe came with test data and has been true to specs. Three jaw chuck run out is less than .001". The lathe cleaned up easily with WD40. I only encountered a couple of minor problems with assembly. The backsplash shield was about 1 inch too long for the lathe. I had to cut the notch longer where the shield fits over the chip pan and use a piece of angle included in the crate to attach the backsplash to lathe on the tailstock end.
Also you need to loosen the switch box that the forward/reverse switch lever rod attaches to so the sling used on the headstock end to lift the lathe will fit without bending the box.
My lathe came with a nice LED work light instead of the halogen.
I purchased the lathe in December '16, and while it was a chore to setup and connect to 220V, it was worth the effort. I don't have a lot of experience with lathes, but I did have a small bench top lathe for a few years. I setup the stand with the lathe on top to align the holes before drilling in the floor, but I see another reviewer used clamps to attach the stand to the floor, which I recommend. The lathe is pretty heavy and being able to attach the stand to the floor before setting the lathe on it eliminates having to lift it again. I installed it in a 2-car garage using an engine hoist. The lathe arrived promptly and. the mover helped push it into the garage. I had bought a HF engine hoist ($199) and a couple nylon lifting straps ($40) in preparation. It can be setup in a weekend, a single day even if you know exactly what you are doing, but it took me two weekends. One to do the lifting and physical install and another to do the electrical, break-in and testing. After inventorying everything, cleaning it and putting all of the accessories away, it took me some time to get the lifting belts situated correctly. An engine hoist is kind of low for this task and something as long and heavy as a lathe will tilt badly unless the belts are just right. It was easy to roll the hoist around with the lathe attached, but the long legs of the hoist make it quite awkward to position, especially around the lathe stand. If you are doing this by yourself using an engine hoist, expect it to take some time and be patient and careful. I thought about putting it on a heavy workbench, but I am glad I went through the trouble of installing the stand. It is so much more rigid and probably cuts much smoother because of it. The second weekend involved wiring 220v in my garage. I found that I had exactly one spot free for a 2 pole circuit breaker, but only if I repositioned a couple of existing breakers. That and a couple trips to Home Depot ate up some time. Also, put the plug on the Lathe BEFORE you install it. I left some room between the wall and the lathe, but not a lot, and what should have taken 10 minutes to do, took an hour. If I had thought about installing the plug first, then I would have probably put the lathe closer to the wall. But it is also nice to have some space for shelving at the height of the backlash. After the electrical, I did the tests and break-in. The speed and gear change levers are easy enough to move, but you have to get used to when they are in the right position and gears are meshed and when they are not. And don't move any of them when the motor is on. You can operate the apron controls when the motor is on, but not the headstock controls. You will grind the gears. The lathe is noisy in the beginning, but after the almost 2 hour breaking procedure, it quiets down a lot. I was worried at first because of the noise (I want to work late), but after the break in it is about as noisy as a washing machine. I am quite happy with that aspect. I have already made a few parts and finish is really nice. Better than I had expected. And unlike my previous cheap bench top lathe, I didn't have to strip it down and reassemble everything. It was in good shape right out of the crate, after cleaning off the grease they put on to keep it from rusting. The only issue I have had is that the LED work lamp quit working. I need to look at the wiring because it is the LED kind and I didn't expect to have any issues with that, like some have had with the halogen model. In any event, I am really pleased.
I got my Grizzly G4003G 5 days after I placed the order. UPS freight delivered the machine safely. And right to the garage door as I asked them to. Lift-Gate service is very convenient.
The machine is very heavy. I bought 2 ton Shop Crane in the Harbor Freight store and used it to put the lathe on the stand. I wasn't able do it alone, so I used help of my friend.
Connecting electricity also proved to be not too difficult. A licensed electrician spent few hours on it.
Be sure to check the oil! In my lathe oil has not been filled at all.
General impression of the operation of the machine:
1. Operation is not very noisy.
2. The axes movement is very smooth and reliable.
3. Cuts thread perfectly.
4. Very conveniently changes machine's forward and reverse directions speed with just one handle, which is in the right place.
5. 3-jaws 6â€ chuck is perfectly fitted and balanced.
Lathe's manufacturing date is June 2015. The machine has spent more than one year in the warehouse. But it was storaged correctly, the machine is not rusty and works great.
In general, the lathe is very good. I'm happy with it. It is a professional power tool for the affordable price.
I recommend it to anyone who wants to get the right professional lathe for the right money!
Received the lathe in good order and UPS Freight did a good job including liftgate delivery. No problem installing the lathe by myself using a Harbor Freight engine hoist. Made sure to move all the heavy stuff (carriage, tailstock) to the heavy end and lifted with a chain. That left the light end weighing about 40 lbs. Moved it around (slowly) with the engine hoist and a creeper under the light end. When it came time to lift it onto the cabinets, lifted the light end with one hand and put wood blocks/concrete blocks under in 6" increments while raising the heavy end in corresponding increments with the engine hoist. The final step was the light end onto the cabinet with the chip pan in place and then the heavy end set down with the engine hoist. Got the holes lined up and bolts started in about 10 minutes. The headstock had no oil in it from the factory. 4 qts of Valvoline 40 weight took care of that. The carriage had some oil in it, but was a little low. Topped that off too. All in all, the lathe works great! Wonderful replacement for my starter lathe that I have been using for about a year. The owner's manual gives you an example of 13 TPI threading. Wait til you try metric. Lots of surprises when changing the gears. Took me about 2 to 3 hours to get that set up the first time. Now that I have some things straightened out, it will take about half an hour next time. Don't look for the manual to help you on that. Once set up, the lathe cuts accurate threads. I love the location of the spindle lever (turns the spindle on and off with forward/reverse feature). Makes threading and all turning operations a breeze. It's right where your hand wants to go as you are using the lathe. I took the vertical piece of sheet metal that spans the space between the two cabinets and cut it with a torch and bent the edges 1" 90 degrees. Took the brackets and redrilled holes so they would mount horizontal and mounted the sheet metal to make a nice shelf in between the cabinets. Lots of unused space down there. In homage to Grizzly I took the fancy medallion and mounted it on the door of the larger cabinet. The lathe comes with a nice piston type quick change tool post. It is probably me, but I just don't like the action of the piston lock. I modified the mount a little and installed my BXA wedge type quick change tool post and now I'm happy with that.
Still making little tweaks, but all in all, I really like the lathe. I'm pretty sure it is all I will ever need in my lifetime. Lots of capabilities that I never had. Not sure how it will go removing the gap for some of my larger projects that I have planned. At least that option is there. The lathe is just right for me and I don't think I will ever regret the money spent.
I purchased this lathe and probably within a week it was in my shop. I had a friend of mine with a engine hoist assist me in lifting it up to the stand. I took my time and in amazement It went faster than expected and everything aligned pretty easy. I did have to adjust the brackets to the front panel of the stand but it was no biggy. I am just glad I can do some barrels and other big jobs from my mini lathe.
I ordered my Lathe and in less than a week it was delivered. I was actually startled when Fex Ex freight called announced that it would be delivered soon. With the help of some friends and a forklift we set the machine up. The stand leaves much to be desired, in fact I could have built a better one on my worst day. Unless it's properly anchored, the machine can easily tip over causing great injury and damage. If it were 6 inches wider, it would be much safer to handle. I will build a nice solid table with shelves and drawers to store the tooling underneath the machine. The dump will be a nice new home for the stand.
The machine itself is fantastic. It is well built and is of great quality and I'm sure it will hold tight tolerances. The electrical was easy to hook up and it runs smoothly after running it in according to the manual.
If this machine was available without the stand, it would be a fantastic lathe for under $3000.00
I have had this lathe since October and have done several small projects on it. It was a bit more difficult to install than the instructions implied. The lathe weighs 1000 pounds and I had no ceiling height to use a forklift, so did it with a shop crane. You need a buddy to help with this. You cannot assemble the base, bolt it to the floor, and then place the lathe on it. You must place the lathe on the loosely assembled base so you can line up the mounting bolts to the holes. Then I found that toe clamping it to the floor was easier to do than marking the holes through the base, moving the machine, and drilling the holes and moving the machine back. There was no room in the pockets provided for the floor bolts. Once leveled, and clamped to the floor at 8 places, this machine is surprisingly accurate. Several things I did not like: Bolts that hold compound are indexed in the cross slide so as to make it impossible to lock it down at 90 degrees. Carriage and cross slide locks are wimpy setscrews, but seem to work minimally. Machine was a bit noisy But is quieting down as it is broken in. There are several chips and scuffs in the paint and labels. Carriage handwheel set screws are in an inconvenient location to set zero. The swinging cover at the spider bolts at rear of spindle is just plain in the way, making indication of long shaft difficult, unless you remove it. Still, I have wanted my own lathe for 40 years, and now I have one, and it is nice to make projects any time I want.
