Longworth Chuck for the Lathe

[@dakotamax2]

Best instruction video for a DIY Longworth chuck on KZbin. As a trained Draftsman, I had to smile at the inking edge on your triangle. One idea that may help with friction is to add heat shrink tubing over the threads of the bolts.

[@jarmstrong2843]

This is a neat tool to make. I wish my Jet 1221vs had a head stock that would rotate 90 degrees. As it currently stands, I ‘d have to reduce the pattern 50% to get it to work on my lathe. Not sure if it would work well on a greatly reduced scale. Thanks for sharing this neat project. Mucho Gracias, Daniel!! 👍👍👍👍👍

[@DanielVilarino]

Hi John! Thank you so much, my dear friend, for watching the video and for your nice comments. The beauty of the Longworth chuck is that you can make it as large or small as you want. perhaps, one idea, is to make it just with 6 grooves. Instead of dividing the circle in 8 sectors, you need a square with a 60° angle and you can divide it in 6 sectors. I have seen Longworth chucks of several sizes. If you check the presentation during the video, you will see that I do not give particular measures. Just trace a circle 3/4 of an inch from the larger border, then another 1/2 of an inch from the faceplate radius and then look for the middle point between the two and through there trace another circle. If you do the 6 gripper chuck, you probably can get all the grooves to reach the internal circle and for a small chuck probably that will not affect its integrity. Also, in this one, I used 5/16 router bit and bolts, but you can do a chuck with a 1/4 router bit and bolts if the size is smaller and that should work great. Take care of yourself and be healthy!

Very nice work! I just found your channel looking for info on Longworth chucks, I hadn't thought of making my own. I had a similar problem with threads binding while sliding in wood. I cut some brass tubing to fit over the threads and no more binding.

[@DanielVilarino]

Hi Brad! Thank you so much, my dear friend, for watching the video and for the nice comments! Also, thank you for the tip about the brass tubing, that is a nice touch! Cheers! Daniel

[@jerrywalters9683]

Excellent video Daniel! I am a big fan of Longworth chucks and have made 6 (for myself and others) over the last 8 years. I too started with the largest size that would fit on my lath. I found it to be unwieldy when working on smaller size bowls. Once you have made one, it is easy to make another. My most often used size is 12" in diameter. For that size and smaller you only need 6 bumpers. The layout for that is much easier than for 8 bumpers. The spacing is the same as the radius. I also like #3 rubber stoppers for the bumpers. They are taller and squeeze out more when tightened to form around the lip of the bowl and hold it more securely to the face of the chuck. Applying two coats of paste wax to the mating surfaces of the chuck helps to reduce friction when adjusting the chuck. Best wishes to you and your family.

[@DanielVilarino]

Hi Jerry! Hi my friend! Thank you so much for the comment! I am really glad you liked it! Yes, I can imagine, I will probably do myself a smaller one with just 6 grooves. I do have the Cole jaws, the large ones, and for the moment that is what I used. But I think a smaller Longworth would be a nice addition to the arsenal. Yes, I did not find those bumpers in the Home Depot, must have been some other aisle, but I saw they sell them in amazon, so I might get them from there. I may also get longer bolts that have threads just in the tip for those. I sanded really well the surfaces that touch each other, so for the moment they slide without trouble, but I am planning in following your advice soon. Cheers and keep yourself and your loved ones healthy and safe! Daniel

[@jerrywalters9683]

@@DanielVilarino I started with black stoppers (like those used in science labs) that I purchased from my local ACE Hardware. After 5 years in Arizona, they start to dry out and crack. I've been replacing them with white stoppers purchased from Amazon. I used the same technique as you to drill the bolt holes. You can purchase stoppers with holes pre-drilled.

NIce project mate. I made one based on your video and it was easy after watching you do it.

Hi Daniel, That was a lot of work. The end result is brilliant. My lathe has a 16" capacity but my big cole jaws will only let me get to 14". Once you have posted the beam compass and the router circle cutting jig I will email you for the Power Point with the detailed plans as I think this will be very useful to have. If I was to buy a 16" it would be £160 nearly $200. Brilliant Daniel. Take care my friend. Cheers, Huw

[@tomcoker9882]

Hi Daniel, you might try some heat shrink tubing on the bolt threads and maybe some CA th harden the inside edges of the groves. Then a little wax and you should have a smooth running set of holders. Cheers, Tom

Welcome back Daniel. I missed your uploads in recent months. As always, your turning is masterful, but as an Irishman the drink you recommended would not be acceptable here. We would instead fill it with whiskey to keep us going through all weathers.

[@DanielVilarino]

Hi Alan! Thank you so much, my dear friend, for your nice comments. Hahahahaha! You know, there is a version of the mate, particularly in the south of Brazil, in which they use a pinapple, they cut the top, and with a knife they sort of cut the inside so that it becomes loose and in small pieces (that would replace the Yerba) and then, they use Cachaça, a type of white liquor, like vodka or similar, instead of hot water, hahahaha! I can tell you that after a few of those, the only thing you want is to sleep it off on a bed!!

AWESOME JOB, AND THANK YOU MUCH FOR SHARING!!! WHAT'S THE MAX RPM YOU WOULD DARE RUN THAT CHUCK? TAKE CARE!!!

[@DanielVilarino]

Hi my friend! Thank you so much for the comment! I am really glad you liked it! I would say that no more than 800 RPMs. I think I feel comfortable between 500 and 600. And I will probably will have to add a set screw to the faceplate to lock it in place in the lathe axis, since the mass of the chuck is huge and has a lot of inertia, so, if you do not watch it, after turning off the lathe, it keeps rotating, sometimes faster than the axis itself and that can disengage it from the axis screw. So a set screw should solve that. Cheers and keep yourself and your loved ones healthy and safe! Daniel

[@hobonickel840]

This was very inspiring... Do you think this would work for a smaller finger gripping radius by only using three fingers and enlarging the size of the fingers ..ex: instead of 1" diameter rubber stopper you make it much larger like 5+ inches so it can reach in further???

[@DanielVilarino]

Hi my friend! Thank you for watching the video and for the comment. Yes, you can remove the 4 fingers that do not reach all the way to the center, and you can certainly use larger diameter stoppers, but there is a practical size, because if they are too large, the space between 4 circumferences placed tangential to each other will limit how big they are. Cheers! Daniel

Hola Manuel! Muchas gracias por tu correo y disculpas por la demora pero apretó el trabajo en la oficina y se me atrasó responder comentarios. No conocía el torno Truper modelo 900, así que investigué un poco y encontré que viene con dos tipos de tornillo en el eje. El husillo parece tener una Rosca M18 x 2.5 o 1 1/8" x 12. Habría que ver cuál de las dos es. La medida métrica M18 x 2.5 no es muy común. La de 1 1/8 x 12 es un poco más común, pero es en pulgadas. Sería importante determinar en el caso de tu torno, cuál es la medida, para ver qué plato le va, o si es necesario conseguir un adaptador. Un abrazo fuerte! Daniel

Hi Daniel, Nice and clear video and I admire the precision of your work. Can you share the dimensions of your router bit with us (cutting diameter, effective cutting length and shaft diameter. I struggle to find a suitable 6mm cutting diameter bit that can cut through 2 x 18mm multiples ( all to short with shaft of 8mm)

[@DanielVilarino]

Hi Cees! Thank you, my dear friend, for your nice comments and for watching the video. Sure, that bit is a Freud 04-118 Double Flute Straight Bit. Unfortunately, the dimensions for this bit are in inches. It has a cutting diameter of 5/16 of an inch (that is 7.9375mm), the effective cutting length is 1inch (25.4mm) and the shaft diameter is 1/4 inch (6.35mm). For this particular bit I had to use the router adapter, since my router has capacity for shafts of 1/2 inch (12.7mm), I do not know if Freud has metric router bits. I know they have one of 1/4 inch cutting diameter (6.35mm). I am not sure if your application needs precise 6mm router bits. Is the shank of your router metric or in inches? Amana has a 6mm straight bit with 25 mm cutting length, but the shaft is also metric of 6mm. I hope this helps! Cheers! Daniel

[@DanielVilarino]

Hi Bill! Thank you for watching the video, my friend, and for the comments. I used 3/4" plywood because with such a large diameters things tend to flex, particularly when holding a big piece. I know that 3/4" plywood will make the chuck 50% heavier and a bit more difficult to handle, but doing it with 1/2" may be a bit riskier. Please send me a message to [e-mail] and I will forward you the PowerPoint presentation with all the construction instructions. Cheers! Daniel

O me notifica tarde. Creo que en tu caso, probablemente, el de 3.5 sea más práctico. Por lo que me comentás, parecería que el torno es relativamente pequeño y un mandril de 5 pulgadas, no solo es más voluminoso sino también bastante más pesado y puede darle demasiada inercia al motor. Sabés cuántos caballos tiene el motor del torno? Un gran abrazo! Daniel

[@teamwild_UK]

Another fantastic project Daniel. 👏 I don’t quite follow why, when at its smallest diameter, there are longer tracks flowing to the centre. Was this a mistake? I think I shall make one out of cardboard to fully understand the geometry before making one in wood. All the best. Ben

[@DanielVilarino]

Hi Ben! Thank you, my dear friend, for your nice comments and for watching the video. No, that was on purpose. If you check minute 38:43 of the video, you will see that by removing the rubber gripers in the shorter tracks, you can use the ones in the longer tracks to get to hold a much smaller bowl. Though it is with just 4 grippers, because the bowl diameter is small, that is still a good hold. Then, for larger bowls you use all 8 grippers. The reason why not all 8 tracks go to the center is because that would weaken a lot the center of the disc, since the tracks would pass very close one to the other if all 8 reached the inner circle. By doing the alternate size in the tracks, you have a more versatile chuck. Other solution is to make all short and then have another Longworth chuck, smaller, with 6 tracks instead of 8, that could go farther inside. Or just use Cole jaws for smaller pieces. Let me know if that makes sense and if you want the Power Point, send me an e-mail to [e-mail]. Sometimes looking at the slides (which appear during the video but in a smaller size) everything makes more sense. Best regards, daniel

Buen día como funciona esa mascarilla

[@DanielVilarino]

Hola Manuel! Muchas gracias, amigo mío por ver el video y por comentar. La mascarilla forma un recinto relativamente cerrado sobre tu cara. Tiene un tubo que la conecta a un ventilador y filtro que se ajusta con un cinto a la cintura. El aire del taller (que típicamente tiene polvo suspendido) es chupado por el ventilador y pasado por el filtro. De ahí el ventilador lo empuja, ya purificado, por el tubo hacia el recinto de la máscara. El aire es fresco y general una ligera presión positiva en el recinto que evita el ingreso de polvo fino al mismo. Además, como en mi caso, que uso lentes, ese aire evita el empañamiento de los mismo y también de la careta de la máscara. Es un sistema un poco caro, pero sufro de bronquitis crónica por un trabajo que tuve antes en la industria química y no quiero jugar con mis pulmones. Un gran abrazo! Daniel

What was the purpose of the 8 small holes you drilled on the one side of the chuck?

[@DanielVilarino]

Thank you very much, my friend, for watching the video and leaving a comment! I believe you may be referring to the homemade faceplate that it is attached to the backside of the Longworth Chuck. Basically, I made these faceplates in this video: kzbin.info/www/bejne/p5bFfZh6o514brs and dedicated one of them to the Longworth. That way it can easily be mounted to the lathe axis. These faceplates have 8 holes for 8 screws. Hopefully that answer your question but if it is something different, please let me know in what minute of the video you see those 8 holes you are referring to. Cheers! Daniel

[@tschmath]

@@DanielVilarino I’m talking about the holes you made where you had to adjust the one curved rout to not hit the hole you had drilled.

[@DanielVilarino]

@@tschmath Got it! Thank you for clarifying. Those eight small perforations are to hold the point of the router jig. The center of the jig slides on a groove until you fix it in position with the knob. The knob tightens on a bolt that on one end has a point and on the other has a small cylinder. So you can use the router either way, on a point or on a small perforation. I prefer the small perforation for this project, because provides a more secure holding for the center of the jig. The following video shows how I made the router jig, and in the minute 3:05 of that video, I show how I grinded the bolt to make the cylinder on one end and the point on the other. So, the eight small holes purpose is to provide a secure placement for the router jig center. I hope this explains and let me know if you have any additional questions or comments! Cheers! Daniel

[@DanielVilarino]

Hola Edgar! Te agradezco mucho, estimado amigo, por haber visto el video. Cuando uno realiza el torneado de un cuenco o un plato, por lo general forma, en la base del mismo, una espiga de agarre o una ranura circular de agarre. A veces, la ranura puede quedar como base, si la misma se hace bien prolija. Otros métodos de agarre incluyen atornillar la pieza de madera o pegarla a un bloque de sacrificio. En muchos caso, luego de terminar el torneado de la parte externa, la boca y la parte interna, queda pendiente atrapar el cuenco para finalizar la base. Este plato, con sus ocho tapones sujetadores que tienen una forma ligeramente cónica, presionan contra el borde de la boca del cuenco o plato y dejan expuesta la base del mismo, facilitando el trabajo y terminación de la misma. Ojalá esto responda tu pregunta, pero si te quedan dudas no dejes de consultar. Un fuerte abrazo y mantente sano y seguro! Daniel

[@haribabu8138]

it is useful for what?

[@DanielVilarino]

Hi Hari Babu! Thank you so much, my friend, for the comments! The Longworth chuck is useful to turn, particularly, the bottom of bowls. During the process of wood turning a piece, like a bowl or a plate, many time, because of the type of holding you use initially, faceplate, glue block, mortise, tenon, etc. the process may require, at the end, to hold the piece on the rim, so that the bottom is exposed and then you can freely work on it without the hindering of the tailstock and the live centers. The Longworth chuck captures the rim of the plate or bowl with its rubber bumpers, and since they have a conical shape, when you tighten them, the press against the rim pushing it against the surface of the disc. That is a very secure hold, even for large bowls as shown in the video. And once you have the bowl or plate held that way, you can then approach the tool rest and work on the base, giving it a nice shape, making a recess to put your makers mark or whatever decoration you want. I hope this helps, but if you have any other comments or questions, let me know. Cheers! And keep yourself and your loved ones healthy! Daniel
