    I have not changed my mind about the G0698

    Hello all,

    In light of all the different postings and responses I have given to others, I just wanted to state my feelings as of now. I still think the lathe is a good machine, comparable in quality and value to Jet and others, and has more capacity. I do not regret buying it, as I feel it is a good value with excellent features.

    My only problem is that instead of just an option to return it, or live with the low rpm "pulsing/ searching" issue, I believe there is a fix if Grizzly would just turn their heads in that direction, and pursue it. I believe technically speaking that this is very achievable goal to eliminate this pulsing at low rpm, but my feeling, again my personal opinion, is that they think the easiest way for them to address it is to change their specs and leave it like it is.

    They have not impressed me with this approach, and I wish they would contact me and tell me that they would do their best to remedy this for me as one of their valued customers. Overall, I still like the lathe, and do not think that this issue will prevent me from obtaining good turning results.

    I am having second thoughts about any future purchases, and I have plans to build a new shop and equip it with some new machinery, when I am able, and I am waiting to see how they ultimately deal with this problem.

    As of now I wonder how I am viewed by them ... am I really a VALUED customer?

    The performance is definately there!

    Hi all,

    After my last post about still liking the G0698 lathe, I decided it was time to get back into the shop and turn something else. It has been snowing here in Virginia and has been hard to get into turning as we have had 2 blizzards in a row.

    Anyway, I got a couple of cherry blanks from a tree cut down last June in a friends yard, and I had made turning blanks from the logs. Man, was this stuff hard! I ended up with a blank from the half logs that were about 14 or so inches, and cut them on the bandsaw, and they were too thick to cut them mostly round because it caught on the blade support on my saw, so they were not round, and very out of balance.

    I mounted one of them using the 8" faceplate that came with the lathe, and proceeded to turn round, using a 1/2" bowl gouge with a long side grind on it.

    I had to use the slower rpm settings and turned the blank at first around 180 rpm, and gradually upped the speed as the blank got truer. This lathe never bogged down, and only vibrated when I turned it up to a higher rpm than was called for. The lathe did not walk, and it almost "speaks" as to the correct range by the smoothness and setting for the speed dial. I have learned that your tools [gouges etc.] will let you know about your technique when they do what you want and when they don't give you the cut you desire. [I digress]

    Even though I was turning a lot of "shadow line" such as you would with a natural edge bowl, and I did get a few catches, this thing really performed. It did take to heavy a cut twice, and the lathe just stopped, like it is designed to do, and I turned down the speed dial, hit the off button and reset the breaker, and off she goes. This is a great safety feature!

    I just wanted those who are following these series of posts, and who may have misunderstood the frustration over what I consider a minor issue, to know this thing rocks! I still believe the minor issue of "Pulsing/searching" at low rpm could be addressed and remedied if Grizzly had a mind to do so. I can only surmise that they may feel like they have to change their customer service policy in order to accomodate my wishes.

    I think the lathe is a great value, and boy so far, it really performs! Personally, I don't think anyone has anything to fear from purchasing this lathe. It, in my opinion, is more likely to pleasantly surprise you with its performance.

    I do think in the future that I am going to add the boards for a bottom shelf to stiffen and add balast. It just makes sense if one is going to be turning larger, heavy and out- of -round projects.

    I wrote to Bill Crofutt at Grizzly expressing my concerns about the G0698.


    Here is my Question:

    Bill this is the last post in this thread you my want to check it out.

    http://www.aawforum.org/vbforum/showthread.php?t=6877&page=9

    Grizzly's 'supposed' response has me wondering. I did see the RPM's stated on the web site before & after the change & I do have all the print outs available from the web site for this G0698 lathe. It would be better of the low speed settings lowest speed was about 100 RPM'd less than 330 RPM or even lower though because these speeds don't even allow anyone to use the speed chart to match the speed up to the diameter of wood being turned. I was planning to purchase one of these lathes later this year & am saving up to pay cash. Please help out with this if you can Bill.

    Thanks, Bart Leetch

    Here is his answer: Hello Bart,

    I am not a member of this site so I can't post, but feel free to post my response to your question.

    We tested the samples and the production prototypes. All along we knew it would not operate well much below 100rpm. When the manual was written and the spec sheet produced, the writers noted it was variable speed and that it would stop when turned to the lowest position. They wrote the manual and specification sheet based on the fact it would stop, in other words slow to zero. I didn't notice it when I proofed the documents. We didn't change our specs recently as much as we corrected them. Will it go below 100? Yes. Will it go all the way to zero? Yes. Can it be used at those speeds? Not really.
    It is unlikely these specs will change. We are not looking into changing the design to allow a lower speed.
    In your email below, I read it as though you think the lowest speed is 330rpm. Maybe I misunderstood, but the lowest useable speed is 100 spindle rpm.

    Thanks Bart, let me know if you have any other questions.

    Bill

    Hello Bart,

    I just got off reading another thread I started about programming an inverter, and Bill Boehme has given me some great info explaining the difficulties with getting below 100 rpm without basically destroying a motor by overheating.

    I think I am going to let this "pulsing/searching" at low rpm rest, and after another turning session this afternoon, man I"ll tell ya, the thing really performs well, and as I have said all along, this pulsing is a very minor issue, and now it has been explained by both Bill Crofutt and Bill Boehme.

    Best of luck! I would not have any hesitation purchasing this lathe again, even with this minor issue, because it is most likely something that doesn't really matter.:cool:

    Headstock Rotation

    Hi, this has been a great thread on this lathe. I was just about to go with either the Jet 1642-2 or the Nova Dvr XP but I am now going to take a much closer look at the G0698.

    My question is have you rotated the Headstock yet? The Catalog page has "Headstock Rotates 180 degrees".

    Can you rotate it say 12 degrees off the bed like the Nova for ease of bowl work?

    I plan to call Grizzly in the morning and see what they are currently quoting for a ship date. I am ready for a bigger lathe and do not want to wait until June.

    Thanks for all the great feedback on this Lathe.

    Headstock rotation

    Hello Frank,

    When I received my G0698, I had to remove the headstock to take it into my shop and set the bed on the legs. One could very easily rotate the headstock 180 degrees, simply by unscrewing the nut on the bottom of the threaded shaft that the lock down handle is connected to. If one really wanted they could totally reverse the set up of the lathe for a left handed user. Could not be simpler!

    I hope that Grizzly has one in stock for you. I really like this lathe, and if you follow the postings on my other thread "reprogramming an inverter" then you will see that the "pulsing/searching" issue is really not an issue, but the nature of the beast when it comes to inverters. Pay attention to Bill Boehme's posting. He is an electrical engineer with much experience.

    The lathe has great features and a great value - [IMHO] good luck! Oh by the way, no it will not go 12 degrees like the nova dvr, but you can slide the heastock to the end of the ways and turn off the end, by using an outboard tool rest. That gives you probably 26-28 inches swing for turning something like a large platter. Nova handles their ourboard turning by rotation of the headstock at an angle to the bed ways, to save from having to reach over to hollow out a bowl, but this lathe allows for sliding the headstock to the end to hollow out in a very natural standing position, both are equally good.

    Thanks Roger

    I will post what I find out about shipping time from Grizzly tomorrow.

    I can re-arrange my shop and make room at the far right end so I could turn with the outrigger. The Nova would definitely fit better the way I have it set up now. However the biggest blanks I have now in my stock pile are about 17" so the G0698 would work "out of the box".

    Frank,

    You could rig an out board rest using a roller stand or some other shop made rest and it would not be necessary to have the outrigger attachment, although that would be a nice thing to have! Good luck and good turning!:)

    Backordered

    Well the first 10 must be gone from the PA warehouse. I just checked this morning and they are back ordered. For those of you on the west coast they may be a little sooner than that.

    Now I have to decide if I am going to wait for the G0698 or go with a machine closer at hand. The Jet 1648's are showing as in stock at Amazon/Woodcraft.

    Differences between Grizzly and Laguna Lathes

    I'm just getting my first lathe, and found this thread very informative. I decided on the Laguna 18/47 Platinum, and it should arrive by the end of the week. I asked them about the resemblance to the Grizzly and why theirs cost more, and he said primarily that their motors have constant torque monitoring and there is a hand wheel on the headstock, two features that the Grizzly lathes don't have.

    Torque monitoring / encoder in the motor?

    Hi Joe,

    I started another thread asking Bill Boehme about "constant torque monitoring" and that will be interesting to hear his answer as to if that is what prevents 'pulsing/hunting" at low rpm. This might be a reason for the difference between the lathes [and the hand wheel of course] or it might be a sales gimmick or it could be what Luguna calls an "encoder in the motor" that perhaps was left out of the Grizzly version.

    I am anxious to hear from Bill

    Hello Frank,

    I own a Laguna 18/47 and I have rotated the headstock, twice this week. I wanted to turn two vessels from the other side, but my lathe is too tight to the wall to get behind it, so I turned the headstock around. It only turns 180 degrees due to a cast tenon that slides between the ways of the lathe.

    It works so good that I'm thinking of making a remote for the controls that parallels the original controls so you don't have to reach around the headstock. I'll wait until the warranty is done though.

    Good luck deciding which lathe to spend your hard earned money on, it took me a year to decide.

    Tom

    issue of "constant torque monitoring"

    Hi all,
    I would like to refer anyone interested to Bill Boehme's reply to my question on another thread about "constant torque monitoring." It might be helpful as to the differences claimed by some in the different models that compare to the G0698.

    We are interested in the facts, and want all who are interested in this model lathe to have the correct information. Very interesting and draw your own conclusions.;)

    I decided to return my lathe

    I was the guy referred to in some of the postings as having trouble with serious pulsing below 100 rpm. I have been following this thread closely but remained on the sidelines since most of the information was being accurately reported. I just decided to finally post my final resolution and actually defend Grizzly a little bit. The lathe is currently on a truck on its way back to Grizzly in Missouri. I really wanted this lathe to work out but since Grizzly couldn't do anything to change the low speed problem I decided not to keep it. I will give credit to their customer service because they were very polite through the whole process and agreed to take it back and give me a full refund. There has been a lot stated about never needing that slow of a speed to turn something and I agree, but in my case I wanted the slower speeds for sanding natural edged (wings) or warped vessels. I also wanted this to be the last lathe I purchase and I am sure I would have wanted to upgrade sooner or later. I never did get into a discussion with Grizzly about the tailstock since it seemed pointless when I wasn't going to keep it but that also added to my decision not to keep it. Again I thank Grizzly customer service for stepping up and giving me the option to return it and essentially have a "do over".

    Terry

    Grizzly's customer service

    Hi Terry,

    I too am pleased with the customer service of Grizzly. I had some misunderstanding with them related to the "pulsing at low rpm" issue. From what I have learned from their quality assurance person, Bill Crofutt, and from the electrical engineer Bill Boehme, it was mostly my lack of knowledge that caused me to "push this issue." If the tech guys would have explained the issues the way Mr. Crofutt has done, I would not have pushed it, so it was a communication problem.

    I have since been told by owners of 3520b that theirs cut off at 50 rpm. and this helps me to know that this is the nature of the beast, and any lower rpm could overheat the motor, and result in failure, according to Bill Boehme.

    I hope you will be satisfied with whatever is your new choice, and post when you get it. I hope something on this thread was helpful to you.

    I am still very pleased with this machine, and knowing what I know now, and with the performance I have experienced, I would make the same decision to purchase again.

    Questions about the Grizzly G0698

    Roger

    I have some questions about the G0698 . I received mine about 2 weeks ago. My previous lathe was a Harbor Freight so I have limted experance.
    The first is what is the proper way to turn on/off the lathe. Should you reduce the varible speed to zero or leve it at the setting I am using at the time I shut it off?
    Also when I want to stop the lathe to look over what Iam working on is it ok to leave the lathe on and reduce the speed to zero or do I need to sut the lathe off?
    I removed the cover plate from the drive side of the head stock and noticed two threaded holes next to the through hole.(were you would use a puller to remove the pully)
    Could you use these to install a hand wheel? (does this sould like a good idea). Because the through hole is not threaded how would you set up a vaccum chuck?
    Thanks Tom

    your questions on the G0698

    Hello Tom,

    First of all congratulations on your lathe purchase. I believe you will like it and have made a huge leap forward in in your turning capabilities over you afore-mentioned HF.

    I think that the proper way to turn it off is to [first] look at your speed indicator in case you want to go back to that speed again, and then turn the speed dial to zero, and then, if you want to do some adjustments to your chuck or change something, turn it off with the off button. If you just want to take a look all around your blank, you could just move the speed dial to zero. Just don't hit it if you are touching your work.

    As to the possibility of mounting a hand wheel - I think it could be done with an extension to the spindle [shop made or made at a machine shop] that has a flange welded onto it with holes to exactly match up with the holes on the pulley. It would need to be true to avoid vibration, so it would probably take someone who knows how to do work on a metal lathe.

    I think it is a do-able thing, and would be useful for mounting a blank on a screw chuck.

    Let us know how you are doing with it, and give your review as well.

    additional on possible hand wheel

    Tom,

    I forgot to mention that if you do have an extender for the spindle machined, that you need it to have the same size bore as the spindle, so you can still use the knockout bar to remove centers, vacuum chucks, etc.

    You can find that measurement on the specs sheet in your manual.

    Thanks Rodger
    Good point on the through hole in the hand wheel extension. My brother runs a machine shop so I think I’ll see if he can make on out of aluminum.
    I changed the belt to the low speed and my lathe runs fairly constant at 80 rpm.
    It sound like the motor is fluctuating but visually it looks like the chuck is at a constant speed.
    I also found what I think is the MFG web site and notice their Specifications are 130 rpm as the low speed.

    Burt group

    Hello Tom,

    I have seen the web page for Burt Group also, and I don't know the relationship between Burt Group and GeeTech [maybe a holding company ?] which makes most of the woodworking machines that are here in America. Here is the link if you want to take a look:

    http://www.geetech.com.tw/sp.html

    I think making a spindle extender out of aluminum, and making it so that a handwheel could be threaded on or something like that would be a great thing. Since your brother is a machinist, see what he would be willing to do to make one for me also, and get back to me. [this forum allows for private messaging]

    I might be interested in having him to do this for me also, if he can do it well. It would have to be true running to avoid vibration and wobble. It is great to have connections like you do that can help with a part like this!:D
