nice addition
Unit works very well but I had to modify the front bracket to fit my delta lathe. But after that minor issue it has worked very well. I have the extension on my lathe and I can cut the whole length
allowing me to make full length legs.
Really enjoy the duplicator. Would recommend and would buy it again.

Woodworking Experience:
I used this attachment on my metal lathe to cut spindles that were 4 inch dia. 36 inches long. Had to figure out how to attach it to a 1911 lodge and Shipling lathe. Once I did that it worked great. However, turn your work down round before you use the duplicator. I had to put all the metal stuff back on, turn them all down round then put the attachment on and duplicate. Turned about 20 spindles, treated wood knots too. TAKE YOUR TIME

Recieved my dupilcator today. This is a very good duplicator for the money, Yes it does take some setting up, but what piece of equipment doesn't? Took me 1/2 a day to get comfortable with it, but by 7:00pm that night, I was turning out 2-3 26" porch spindles per hour. All in all in my opinion, this was a good purchase, have been very pleased with all of my Rockler purchases.

I've read all of the reviews...
I've read all of the reviews and one thing that hasn't been mentioned is that the duplication of spindles is so precise, that I don't think that, even the pros could resist, by stating that it is so simple and easy to set up, that my grandson and my future niece will be thrilled in way these cradles have turned out. All of the 40 spindles, are exact and true to the only original one that I had left. Making these heirloom baby cradles have been very enjoyable, with the precise duplicating of the spindles. Thanks to Rockler, I have been able to make two baby cradles at the same time.

Lathe duplicator
The manual and installation instructions are poorly I illustrated and minimal. The first issue was the dimensions given for the installation of the supports on the lathe bed which are incorrect. You will have too wing it. Secondly the duplicator was assembled at the factory incorrectly. Took a while to figure out and correct. However when finally assembled and adjusted it worded as advertised. Construction is pretty good. It would however be much better if it came with a replaceable carbide bit same as the Rockler lathe tools. Also suggest the manual be improved and possibly a video on installation and use would be most helpful.

Modifications required to fit to a Woodfast Lathe M910
Just bought this duplicator for my Woodfast Lathe M910. I couldn’t get any confirmation that it would attach to my lathe and as delivered it doesn’t. However, I have two tool rest assemblies and by removing the support rods from the support stands and welding on an extension that fits into my tool rest assembly it works brilliantly and far quicker to set up.

I would suggest that Rockler gets someone to edit the manual as it is in Chinglish and figures and part numbers do not align.

Overall a good accessory for a lathe
It is a very good lathe accessory. But I had to buy some threaded rod to attach the duplicator to my lathe. The ones that came with it were about a half inch to short.

Woodworking Experience:
Unit works well as it should. Some difficulty setting up, but not too much. About 3 hours. Would like the hand wheel to be a little larger with a spinner handle. Desperately needs a carbide cutter instead of the HSS cutter. HSS cutter on cedar leaves a ragged finish and requires a lot of sanding!

Accomplished mission
I bought this to duplicate 34 spindles. Overall it worked, however on the 3rd spindle the clip nut stripped that locks the depth. I had to use a clamp to make sure the cutter wasn't against the wood due to spring strength. I was able to complete the spindles and they looked good.

Rich S on Jan 26, 2017
Will it work on shopsmith?
A shopper on Apr 26, 2015
BEST ANSWER: I'm not sure that the lathe duplicator will work on the Shopsmith because of how it mounts to the bed (or rails in the shopsmiths case). In the photos you can see there are two knobs that bolt through the bed. Those mounts allow you to move the duplicator in and out to adjust for the diameter of the piece your turning, they are also set so that the tool at the center of the work piece on 12" diameter lathes. It might be worth reading through the manual under Technical Specs (page 3) has some pictures of the mounting setup.
Is there any duplicator out there that fits on a Excelsior mini lathe with extension bed ?
Thomas M on Dec 16, 2016
BEST ANSWER: I put mine on and older craftsman lathe with tube type rails had to make some minor alterations but worked great.
will duplicator work with a jet 1442 lathe?
A shopper on Jun 1, 2015
BEST ANSWER: The duplicator will work with any lathe. The issue is you may have to do some minor mods to the mounting brackets to make it work for your machine. It is not made for universal mounting but, hey, we are all woodworkers always making jigs and mods to make other things work.
will this duplicator work on a craftsman 12 inch? I'm not sure about the mounting.
Robert L on Jul 25, 2016
Will it work on jet 1220?
A shopper on Apr 25, 2015
BEST ANSWER: I do not know. I have a Harbor Fright 36" lathe and it works great on it.
Will this duplicator fit a Jet Midi lathe?
Donn W on Oct 6, 2019
BEST ANSWER: Not the 1221 model. The lathe bed is too short. I'm not familiar enough with that lathe, but, you might be able to shorten the duplicator, depending on your metal working skills, and then it might.
Will this work on a 9"x30" lathe?
Matt on Mar 17, 2019
BEST ANSWER: this will work on any lath that is 30 inches or more. It does not work on small diameter spindles. will be good for duplicating table legs and such. Mark Cluff
KENNETH W on Oct 2, 2018
BEST ANSWER: Hi Kenneth,

I am almost certain that yes this will fit on your Delta lathe. I have the Jet 1221 and the curve under the bed has made it difficult for me but I managed. I think it will fit yours just fine and it is a very nice addition and ( turning point haha ) well made. I hope it works for you if you decide to purchase. Good luck Greg
Will this fit my 1980s shop smith?
Fredrick on Aug 30, 2018
BEST ANSWER: In reviewing the Shop Smith Lathes, it appears that this may very well fit your lathe with either no or very little modifications! The one thing that I see that may cause some issues is that on the Shop Smith Lathes, it appears that they use two round bars to slide the head back and forth on. You may need to create some type of a mechanical stop to keep the duplicator from walking on the bars.
I bought one used. Where can I get a manual?
K U on Nov 14, 2015
BEST ANSWER: The Manual is on Rockler's Webpage. Scroll down the lathe duplicator page and there is a link under to "Technical Downloads."
Could this duplicator work with an older craftsman lathe with a flat rail instead of a slotted bed?
Bill T on Feb 5, 2020
BEST ANSWER: Im not certain if it will work or not, as a matter of fact I would recommend that you buy a different brand completely, from day one I was not happy with this product or its performance.
Will this mount to a center tube lathe?
Tyler M on Jan 20, 2020
BEST ANSWER: Probably not. The 4 pieces of metal blocks shown in the picture are used to fix this item to your lathe. Two of the 4 pieces go under the lathe rail and the other 2 stay on top of the rail. The 2 long screws connect and fix them. Then the duplicator hang onto the two poles on the top pieces. So i guess it's designed only to fix onto lathes with rails.
Hello, would the duplicator mount on a Woodfast Lathe M910?
Peter M on Aug 2, 2019
BEST ANSWER: I’m not to sure I have a Central Machinery lathe and I had to buy longer threaded rod so I could clamp the duplicator down. The ones that came with the duplicator were about a half inch too short for the bed of my lathe.
Will this duplicator work on a record lathe?
Mary G on Jul 15, 2019

I'm not at all familiar with a record lathe but from what I saw by looking it up my guess would "not at all" would this work. I also looked and I don't think a record lathe duplicator exists. I could be wrong. Hope this helps.

How much can you take off at one time. Will it work to make a baseball bat ?
Carl T on Oct 17, 2017
BEST ANSWER: Two things: 1) this is for general sizing only, it doesn't take off much at a time 2) You still have to do some sort of finish cut as well as sanding. For something as simple as a baseball bat I do not think it is worth the effort and cost.
Will this work on a Powermatic 3520B?
Tom T on Jul 27, 2017
BEST ANSWER: Interesting. My brother-in-law has the 3520B and I have turned on it. The best answer I can give you is that the duplicator from Rockler has adjustable play on the attatching assembly which says to me that it's possible it would work Just an added note. I have found in my many years on the lathe that a good wire welder and a bit of "Mcguiver" attitude and your wood turning will be much more enjoyable. Keep in mind you will need steady rollers with the smaller diameter and longer turnings. I sure hope I have been of some help.P.S. The thickness of the bed rails on your lathe might be an issue of longer bolts on the duplicator attatchments
will this work on a Lanova 18/36 lathe?
Michael R on Apr 15, 2017
BEST ANSWER: Yes.ive used it on a HF lathe and a Laguna 18/36. Its adjusts to fit.
I recently purchased a NOVA 46000 Comet II 12 Inch by 16 1/2-Inch Variable Speed Midi Lathe with a 23" bed extender attachment. Will this duplicator work with this lathe?
Philip P on Jan 25, 2016
BEST ANSWER: I have a 12" Harbor Fright lath. it is 36" long. If your lathe is 36" long on the working bed then I think it will work. Deryl

Does this duplicator work with a this specific lathe: JET JWL-1642-2EVS, 16"x42"EVS PRO?
Kevin F on Dec 11, 2015
BEST ANSWER: My father , the owner of this lather, who lives in Puerto Rico and dosent speak English,and after I consulted with him this question, said that he is sure it will fit your JET, he owns a 1950 craftsman lather and it worrks perfectly,
Can anyone tell me if it works with a Jet 1014VSI with a bed extender on it; and if not, are there easy modifications that would fix any known issues? Thank you.
Bob F on Aug 31, 2015
BEST ANSWER: It should bolt onto the bed with out a problem, BUT the cutting tool will be an inch too high (since it is designed to fit a 12" lathe). I had to cut an inch off of the bottom of the fixed tubes that are welded to the Main Frame. You loose a set screw but the cutting tool is lined up with the center.
I have a JET 1220VS lathe complete with bed extension, will the duplicator be suitable for use with this machine ?
Greg G on May 17, 2015
BEST ANSWER: It did not fit my Grizzly 16' swing lathe as it was too low for the swing. I had to put 1.5' blocks to raise its height to center line. It was not hard to do, just took some thinking. I really found the handle to move it to be almost useless unless a very light cut was taken but I could just push it instead. I am making dining table chairs with lots of spindles and other than those problems, I have found it to be worth the buy.
Will this fit nova comet II midi lathe I do have a bed extension on it ?
Donald Y on Sep 26, 2019
BEST ANSWER: This duplicator is designed for 14 inch swing unless you can fabricate new brackets it will not fit plus you would have to bolt your lath down due to the weight of the duplicator
