    better way to machine spindle extender

    Hello again Tom,

    I have been thinking a little more on machining a hand wheel for the G0698 that we both have. Before, I mentioned that an extender would need a flange welded on it with holes to line up with the holes in the pulley.

    After giving it more thought, I think a better way would be just to machine the whole thing out of a piece of bar stock that is sufficient to include the flange area next to the pulley, and then slim it down after it is bored [boring the hole should be done as a first step]to match up with the center hole in the spindle, and then turn threads or make some other way of attaching the hand wheel that would be secure.

    I think that machining it from one piece of bar stock, would make it run truer and be stronger than welding a flange onto the extender that would attach to the pulley.

    Let me know what you think. I would definitely be interested if your brother could machine a couple for us.

    I have been working up a one piece design and think Delrin would work as a material. I could use my wood lathe to make it and its not very expensive. At the same time I want to make a vaccuum chuck adapter like the one on Joe Wookworker out of the same material. Ill let you know what I come up with.

    Delrin?

    Tom,

    Sounds great. When you get it worked out, some pics posted would be a great help. I am not familiar with "Delrin" as a material, but I will google it to see what I can find out about it. Thanks!

    I googled the Delrin and got the following page which has 2 inch rods sold by the foot . . .

    Another Bowl - almost finished -the saga continues

    Hi all,

    In the continuing saga of the newly marketed G0698, I just finished another bowl on it, as far as turning goes. I have applied 3 coats of danish oil on it, and am waiting a week or 10 days for it to completely dry. After that I am going to use my Beall buffing system on it for the first time on this lathe.

    This blank of wild cherry[really hard] only yielded an 8-5/8 inch diameter bowl about 4 inches deep due to some pretty bad checking in the wood, of which I did some repair using CA glue.

    The only reason I post about this, is that I mentioned in the first post that I would give some ongoing reviews as I used the lathe to turn, as this is a new model for Grizzly on the market, and there seemed to be a good bit of interest, and I have been getting a lot of questions about it.

    So far, I am really pleased with the performance. The more I use it, the more content I have become in my choice of purchase. This machine is really smooth, has torque to spare, and lends itself to so many different set ups that make it really versatile. I even used the reverse feature for some sanding on this bowl. It has performed flawlessly to date.

    When I get the bowl buffed and finished like I want, I will try to get my son to help me post a couple of pics.

    Thanks for the update Roger - I'm looking forward to seeing a picture of it.

    I noticed that in the message with specifications that your spindle size is M33X3.5.

    My Laguna's spindle is 1-1/4 x 8 tpi. So here's just a little more info in the ongoing saga of small differences between these lathes, most likely made in the same factory.

    I wonder if some of the differences we've noted could be something like Sears used to do. They would approach a manufacturer and take an existing model, change a few little things and call it a Kenmore. Maybe the parent manufacturer of our lathe changes a few things for their customers, Griz and Laguna +?

    G0698 spindle size is 1-1/4"

    Tom,

    My spindle size is the same as the Laguna, 1-1/4 inch x 8 tpi. That metric measurement is something that came from the Burt Group website, and the Hare & Forbes Woodmaster 18x47 machine specs [Australia].

    The Grizzly G0698 has the same specs as the Laguna from what I can tell. The Laguna, Grizzly, Jet & Powermatic are all made by GeeTech. Here is a link: http://www.geetech.com.tw/sp.html

    Maybe that will help others to know the heritage of this machine.

    Problem found with G0698 or new owner of it

    Hello all,

    After owning this new Grizzly G0698 for close to 6 weeks now, I have found that the lathe has come with something that I did not really expect ...........it was what some call a VORTEX. It has sucked me in, and I am finding now that I have this new lathe, I want all [no, NEED] all these new accessories!

    I just don't understand it! The catalog never said anything about a VORTEX, neither did the owners manual, or the website at Grizzly. I have let go of money for a new chuck, new drive centers, new live centers, new aftermarket rests, new texturing tool, and now I find myself looking in the catalogs at new gouges and scrapers.........do they have a local TA [tools anonymous] meeting, like they ones that are held for those addicted to alcohol?

    I will try my best to moderate my behavior, and dial this addiction back to some respectable level, but I may need prayer! :D

    thanks for the encouragement

    Idaho,

    I guess that one has to embrace the VORTEX, not fight it! At least the L.O.M.L.[i think that is "love of my life"] doesn't seem to mind, and is supportive, as she knows that woodturning gives me a creative outlet, and is good for my well-being.

    At least, this rationale seems valid to me, but some may think "he's too far gone already!" :D

    How about a review of you G0698

    Tom,

    Have you got a chance to turn a project or two on your new G0698 yet? If so, how about a little review as to your impressions on the lathe? I know there has been a lot of interest on this new machine that is now on the market, and I think it would be good to get another owners perspective as well as my own out there.

    What projects have you worked on so far?

    Having read this entire epic thread from the beginning, I saw no mention of the fact(?) that the motors of the Griz and Laguna (pictures posted above) are apparently not fan cooled by an external fan, unlike those of the Jet and PM. Curious if any users have checked the case temp. of their motor after lengthy use? Maybe motor design is related to low rpm "hunting"?

    The lack of a handwheel or knob of some kind on the outboard end of the spindle is beyond understanding, and something that surely many owners are working to correct asap. There have been complaints about the cylindrical "knob" on the Jet, but I find it to be ergonomically excellent.

    No heating in motor noticed

    Hello Texian,

    I have taken notice of the motor during turning sessions. I have turned some bowls, some light pulls, some candlestick holders, and have done some other spindle turning just to practice my skills, and I have done buffing with the beall system, and I have placed my hand on the motor while running the lathe on the low belt setting and hollowed out bowls that were blanks of over 12 inches at the maximum rpm of 1200, and also on the high belt setting for finishing cuts on spindles, candlesticks at 3100 rpm and it never showed any sign of heating.

    I don't know if the case design is something that is made to dissipate heat or what, but the motor case never even got warm to the touch.

    Regarding the "knob" [handwheel?] accessory on the Jet, I think that same design could be machined to fit the G0698 Grizzly, and would work well. the only problem is the thing would have to mate up with the pulley which has two holes that are threaded, and would have to have a center bore to match the spindle bore, thus extending the capability to use the knockout rod, and vacuum system.

    Are you interested in this lathe, or considering it as a possible purchase in the future?

    This has been an "Epic" thread hasn't it? I think it has been a good one though, and has certainly helped those who have been interested in this model lathe, don't you think?

    laguna 18/47

    I have just recently purchased a laguna lathe which is similar to the griz lathe. The lathe from laguna was supposed to have a better motor than that of the griz. lathe. Griz has had problems with their lathes at low rpms....jerky rotation up to 100 rpms. That is the sole reason why I purchased the laguna, the rep said they have never had problems with theirs doing that. well, my laguna has the same problems. it is jerky up to 250 rpms.

    Customer service was ok with Laguna, except for the techs and engineers. They thought it was part of their job to make me feel like an imbecile. That is neither here nor there, they are sending me a whole new lathe.

    Salesman was misleading. He said that Malcolm Tibbits loved the lathe when he used it at the club meeting that was held at laguna. I talked to malcolm, and he had really no experience with the lathe. Salesman also said that it would not have the jerkyness of the grizzly.

    Does anyone own a Laguna and have similar problems with their lathe?

    Oh, also forgot the the headsock and tailstock spindles don't line up either!!!

    No differences likely between Grizz & Laguna

    Hello Kevin,

    A question; does your Laguna 18x47 "hunt" on the low belt setting [0-1200] over 100 rpm? The lower setting is designed to give you more torque at low speed, which means due to the step pulley system, the rpms in the motor stay a little higher which affects the spindle rotation and gives extra torque for heavy out-of-balance turning.

    I think that the real story of both the Grizzly and Laguna is that they are the same machine, and just painted differently for the respective vendors. From what I can tell from others who own the Laguna 18x47 that have posted is that they really have liked their machine, and I really like my Grizzly G0698.

    The issue of "hunt" at low rpm is not a problem, it is the programming of the inverter they use, and my Grizz will turn at lower than 100, but it does the "hunt." The difference between the Jet and powermatic 3520b is that they cut off at 50 rpm, and there is nothing more than a very tiny difference in being able to turn at 50 rpm and 100 rpm, even for sanding in my opinion. Some Jet owners have reported some hunt as well as a few of the PM 3520b owners, but some report theirs do not "hunt." I don't know if this is due to the differing observations of the individuals, or if it is something not really looked at closely, or what?

    I will say that the "sales pitch" you got was probably an attempt to make Laguna's version seem better than Grizzly's for the sake of gaining the sale.

    I would like to refer you to a thread I started where I asked an electrical engineer named Bill Boehme on "Constant torque monitoring" the claim made by Laguna, and let you read his response and it might help you. It is on this forum, just look for it.

    Also, I think that the "hunt issue" is way overblown by some, and my own attempt to push the issue on this forum was due to my lack of understanding about the nature of inverters, and between Bill Boehme, and the tech guys and quality assurance engineer at Grizzly who regularly works with the manufacturer, my confidence in this machine became settled. To date it has performed flawlessly, and the performance has been great.

    These are my honest observations and opinions, yours might be different, but I just wanted to give you a sense of the experience of others with this lathe that have posted and maybe give a framework of perspective.

    We would love to hear you post as you go along with a few projects and get your review as to how it is working for you. :)

    center alignment on your lathe

    Kevin,

    My centers were off a little, about 1/64, [the tailstock being the higher of the two] and I looked at the bottom of the tailstock and there was a little paint that was raising it up. I took a file, and gave it a few strokes, and now mine lines up perfectly.

    Something you might want to look at, when you get your replacement.

    no differences

    There probably arent any differences. The only difference probably is the price tag. I wish I would have known.

    The funny thing about it is that laguna told me that they have never heard of such a problem with one of their lathes.

    In my view they have misrepresented their product. Selling it as if malcolm tibbits loved it, theirs differs from grizzly, they have never had that problem.

    A few other things that bother me about the lathe, you have to take the nut off of the banjo to get it off of the lathe. Getting the tailstock off of the lathe is very cumbersome. The tool rest is worth its weight in scrap metal. Do you have the same problems with the grizzly?

    Yesterday I put a 16 inch blank on the lathe of elm, what a horrible wood to turn for torn grain. It was a mystery wood, didn't remain a mystery for long. LOL. The lathe handled it ok. THe blank was 10 inches deep. I stalled the machine about 5 times, but all in all it turned it fine.

    made with liability issues in mind


    Kevin,
    Regarding having to take the nut off the tailstock in order to slide it off the bed, I think that is an intentional design to address possible liability issues in case one would slide it back to far, and it fall and break someones foot. All it amounts to is that they used a little longer bolt for the holddown on the banjo and tailstock and headstock.

    My Grizz has a steel peg that screws into a hole on each end as a safety stop as well. Personally, I have not found it to be anything other than just getting used to the machine the way they have made it. My other lathe would allow the tailstock to slide off the end with out removing the nut, but lawyers are making the manufactures they represent make things idiot-proof as much as possible, and we end up having to adapt to the changes.

    Laguna has put out videos with Alan and Stewart Batty as well, using the lathe, and I saw the Malcomlb Tibbets interview video as well, I just don't remember him actually turning on this machine in the video, but I would take his remarks as factual.

    I only stalled my machine a couple of times, due to my own mis-steps, one of which was I looked away for a second, and my gouge moved into a heavy blank that was unbalanced , and it stopped the machine just like it is supposed to, and I turned the lathe off, hit the reset, and off she goes. This is a great safety feature, and I should have known better than take my eyes off the work!

    What is your issue with the tool rest? Mine looks to be the same as the pics of the Laguna that I have seen. It seems fine to me. I have ordered an aftermarket bowl rest for mine, and I will probably get another aftermarket one, but so far the one that came with the machine seems fine.

    Glad to hear that the motor does not overheat.

    Not planning to buy, as I have Jet 1642-EVS2. Often power sand or apply finish w/ lathe at 100-150 rpm. Very smooth down to 50 rpm and then shuts off.

    I would certainly make a knob or handwheel for the Grizz or Laguna. A hardwood cylinder would do. Drill through for the knockout rod, drill and tap one end to fit the spindle thread, drill and tap a radial hole for set screw.

    Richard,

    I like your idea for a hand wheel. I might give that one a "turn" [pun intended] when I get some time to experiment with things. If I could turn a piece of maple or oak, maybe find some hickory, then I could turn both the spindle extension and handwheel in one continuous piece. Thanks!

    I have one of the earliest Laguna 18/47's shipped. It is over two years old now. I have not seen the Grizzly beyond the pictures in the catalog and posted in various forum threads. I doubt that there are differences in the motor or speed control. There are however differences in the spindle. My two year old Laguna is configured exactly like the Grizzly including the spindle not exiting the head stock enclosure and the pulley with the two holes. However the current Laguna has and extended spindle that is threaded on the outboard end and takes a hand wheel that they provide.

    By the way I am happy with my lathe and it has performed well for two years. I did have some initial problems but was able to iron them out with Laguna very quickly. The problems were things like quality issues with the Banjo and the original Banjo having a slightly undersized tool rest post hole preventing it from taking an aftermarket rest with a 1 inch post.
