I have owned a couple belt drive lathes, one reeves drive and one
variable drive. As they get more use vibration has been a problem. I have replaced the belts. So my question, is the Nova DVD really vibration free and is the motor/computer reliable? Thanks to all that respond. L Bledsoe |

I has been a world of difference from the reeves drive machine I had. Quiet, vibration free, true variable speed. Never any problem.

The vibration can come from a lot of different things. Personally, I
wouldn't have a reeves drive. They always seem to go out or whack. I have a little experience on a DC motor which is variable speed, and a lot of esperience on the 3 phase variable speed lathes (8 years on a PM 3520A and a year on a Robust). I will get to turn on a Nova DVR next month at our local club meeting. By all accounts I have read, it is a fine lathe. There is only one thing I don't like about it from seeing it, and that is the bed sits almost flat on the lathe stand. There is no room to scoop out shavings that fall inbetween the ways. I do prefer a sliding headstock to a pivoting one though. Just more sturdy. I don't think that the belt is usually a contributer to the vibrations. Usually, sticking out too far, turning too fast with an unblanced piece of wood, a flimsy, light weight lathe stand, and worn bearings are the main culprits. robo hippy Gerald Ross wrote: Q47m wrote: I have owned a couple belt drive lathes, one reeves drive and one variable drive.

So my question, is the Nova DVD really vibration free and is the motor/computer reliable? Thanks to all that respond. L Bledsoe I've the DVR XP for a while.. Probably done 200 pieces on it, several of them pushing the edge towards abuse.. The motor is amazing... Smooth, very quiet and has great torque at all speeds.. The computer that monitors the spindle is incredible... Keeps rpm constant under load, 3 adjustments for how much of a catch you need to stop the spindle, etc.. I've pushed the limits several times and got what would have been a bad catch on other lathes.. and all it did was stop the lathe.. Another nice feature of the spindle monitoring is that when it detects a catch and turns off the power, the spindle then free wheels, so it stops quickly.. Compared to my Jet 1442 with Reeves drive, it's about 10 times smoother and quieter.. It's very energy efficient and has enough power for me to not convert it to 220v for the extra 1/4 hp it claims.. Also, your warranty is void if you don't use a surge suppressor and 220v suppressors are out of my price range.. As Reed said, Reeves drives are problematic.. I was always adjusting, fixing or just putting up with small problems on the Jet.. Vibration? The Nova vibrated at certain speeds, but not nearly as much as either of my jet lathes, which I was very happy with until I got the Nova.. The up & down arrows that adjust the speed by 5 rpm let you find the best speed for whatever you're doing, allowing you to eliminate a lot of vibration.. My mistake in buying the xp was in getting the "Universal stand" IMHO, it's a piece of crap and not worthy of such a nice lathe.. I should have bought the cast iron legs, but that would have taken another 4 or 6 weeks to ship and I WANTED the damn lathe ASAP.. I didn't opt for the bed extension, so maybe that contributes to the stand vibrating, but it's very annoying.. It buzzes and clanks and since I hang a lot of stuff on magnets, such as the chuck key, it clangs like hell if I don't ease them onto the magnet.. IMO, there's no substitute for cast iron for absorbing vibration.. Would I spend $2,000 for this lathe again? In a heartbeat.. YMWV mac Please remove splinters before emailing |

I have replaced the belts. So my question, is the Nova DVD really vibration free and is the motor/computer reliable? Thanks to all that respond. L Bledsoe I've had an original DVR and I really like it but there are a few things to note - - the computer control is ok but it it's annoying to have to sit there holding the speed up/down buttons to go from one end of the range to the other (eg when going from drilling or sanding at low speed to turning at much higher speeds). I understand that the DVR XP allows you to program 5 preset speeds though, so this won't be as much of a problem. I'd prefer it if the control panel had a large, raised stop button in case of emergencies. - if something goes wrong with the headstock it's possibly going to be something you can't fix yourself. I've had to send my headstock away for repair once before and I'm again getting an error state message on the console (which you should be able to fix by getting rid of dust around the spindle speed sensor, but I tried that yesterday and it didn't fix it). One good feature of the lathe is that if you open up the control panel you can fit a home-made break out box which gives you access to all the controls when eg. the headstock is rotated or when you're hollowing a large vessel and you don't want to have to reach round for the controls. I've heard that Teknatool are working on their own (wireless?) remote but have heard nothing from them about this in the last year. As for vibration - I've never really used any other lathe so I can't say if it's more or less than normal. There are a couple of locations in the speed range where there's some vibration even with the lathe running without a load, but 5 or 10 rpm either side it's fine. We have an original DVR for our club lathe at it always performs well. If you're not aware - there's a yahoo group at http://groups.yahoo.com/group/teknatool/ and a my family group (I think you need an invite for this, but just ask if you want one). Hope that helps Duncan -- ---------------------------- www.duncanhoyle.com ---------------------------- |

One surge protector for everything including the dishwasher and your 240 VAC air conditioner. Those also need protection. "220 volt" protection means one protector for everything - 120 volt and 240 volts appliances. |

I owned a DVR for about 5 years. Great lathe. The headstock is well
built and, without any load, it did not vibrate. But I did get some vibration from the DVR lathe at certain speeds and certain situations. This was more a problem with the stand that I used and not the headstock (I used the sheet metal stand made by Nova). I also had trouble with any piece of wood that was large and/or the least bit out of round. That is because the machine was not heavy enough for what I was trying to turn. I now own a Oneway 2436. I has a belt drive and again, when spinning without a load there is absolutely no vibraton. It is 900 pounds as opposed to the DVR's 200 lb. Even though I don't get anywhere near the vibration problems with the Oneway, with large and/or out of round logs the fact is vibrations can still be a problem - even with a 900 lb gorilla. With any lathe their seems to be some RPM's that you will get a vibration depending on the load and situation. The point is that your problem is likely more about what you are turning and not a problem with the DVR. Ted J. |

The through head is nice for vacuum chucking, but the factory vacuum adapter prevents the use of the factory knock-out bar.

I didn't realize that since I don't use the Nova bar... I didn't like the "no-knob" design and use the rod from my Jet 1442, so I never realized that the one for the lathe didn't fit... must be a smaller diameter..

I've never used a knockout bar when the vac adapter is on, not only because of the hose, but what would I knock out?? I guess some folks leave the adapter on all the time? mac Please remove splinters before emailing |
