How to Make a Grinding Wheel for the Lathe

How to Make a Grinding Wheel for the Lathe


Hello again. Today I will make a grinding wheel for the
lathe so that I can sharpen all my tools, such as woodturning chisels and other kinds
of chisels. I’ve come up with a system allowing me to
change and tense the sandcloth in an easy and convenient way by simply turning a screw. Here’s a step by step guide of how to make
it. I’ll begin by cutting the wheel out of this
piece of plywood. It has the same diameter as a standard grinding
wheel. I will also machine these other wheels to
which I’ll attach an extension nut. After machining all the pieces, I glue them
together as shown here. When the glue has dried, it will be time to
attach the union nut. I’ll use polyuretane adhesive, although I
could have also used epoxy resin. After two hours, I wipe off all the leftover
glue and get ready to turn the wheel. I’ll adjust all of its surfaces to avoid any
unwanted vibrations. For that, I’ll set my lathe’s speed to medium. 1500 rpm will be more than enough. The edge of the wheel must be at the exact right angle to achieve good results when sharpening. Here I’ll machine a hole 2mm wider than the
diameter of the screw I’ll use. I prepare this groove for
the sandcloth. And now, using an angle grinder I machine this groove in the screw allowing me to tense the cloth. I cut a strip of sandcloth of the appropriate
length. To work out the length, I multiply the diameter
of the wheel by pi and then add however much is missing to reach the screw hole. As you can see, adding the cloth is quite
easy. The screw destabilizes the wheel causing the
lathe to vibrate. It’s nothing major, but still, I will solve
it by adding another screw of similar weight on the opposite side. Now I will machine all the necessary parts
to build the toolrest, as shown. Here I will also glue the threaded rod with
polyuretane adhesive, and while it’s drying I will machine this iron plate I had in my
workshop to protect the wood. I screw it onto this piece, allowing me to
turn the toolrest. I will sand the upper part to make it completely
flat. I set up the whole system and after setting
it to the desired angle I run a quick test. Touching the screws while the wheel is in operation could be dangerous, so I will look for some plastic covers or something like that to cover them on both sides. Everything seems to be working as intended! I’ve used P120 grit sandpaper, but for this
kind of sharpening jobs, I think P240 at 1500 rpm would be enough. Now I will prepare this accessory for sharpening
round bowl turning chisels. The first tests seem to have gone smoothly. And finally I will prepare another accessory
to sharpen gouges with greater diameters with this hardware I had in my workshop. It’s a very simple design and I hope it’ll
work. We will have to make rods of several lengths
adapted to the chisels in our workshop, because not all of them will have the same radius
of curvature. After several tests everything seems to be
working well. In a few days I will put up a video on how
to use this grinding wheel and how to finish sharpening our chisels.

  2. Suso, I want to show you my simple device for sharpening a semicircular cutter: https://www.youtube.com/watch?v=PcBWipW1H6o

  3. Me encanta! Una labor estupenda, tanto en el planteamiento como en la ejecución. Gracias por compartirlo Suso!

  4. Great video! Question would it be possible for you to discuss how you make your table saw height adjustments. Reason, it appears in previous videos that the height adjustment involves you reaching inside and pushing the saw up and down I have always wondered how you have you have managed to set the saw blade height accurately while reaching inside the table saw housing. Possibly a video on advanced basics using your machines. Thank you for sharing your knowledge advice and your meticulous attention to detail and an advanced apology for the silly questions of a simple minded individual.

  5. Maybe English isn't your first, but it's weird to say "I'm gonna machine x y z" every time you make something.
    To me, it's only a word to be used on a lathe.

  6. As always very rational, but why not combine this device with the disk that was removed. To use both wheels for grinding?

  7. Does the gap where the sandpaper goes in the wheel not flap too much when holding something against it ? friendly greetings, Jörgen

  8. As always, very impressive. Also a very clever solution to tighten the sandpaper. Never seen that before.

  9. you have made so simple, solving some complicated issues at little but with elegance ,love the woodturning chisel guide

  10. Enhorabuena por tus proyectos! me parecen todos una pasada y gracias por compartirlos ya que así podamos tomar ideas para hacer algo parecido .Te quería preguntar,que producto es el que pones entre los aros de madera y la tuerca? se ve que es de la marca quilosa no? pero no se lo que es y otra pregunta donde consigues ese tipo de tuerca larga? gracias y gracias por compartir tus proyectos.

  11. Cada vez que me animo a realizar algún proyecto en mi taller observo tus vídeos ya que me dan muchas ideas, definitivamente eres un grande y muy prolijo al trabajar! Éxitos, sigue así! Idolo!

  12. Good job! The tensioning system for the sanding belt was easy, but genious! Very versatile machine, this lathe. Looking forward to what else you can build for it!

  13. great video saw a similar system for locking belts on a few years ago it works well and you dont get or feel a intermittent cut

  14. excellent video …..I thought my toolrest design was pretty smart but yours leaves mine in the dark…….my next project……thanks great ideas

  15. Really nice build Suso! In the US we commonly see 6" and 8" bench grinder wheels. What is the diameter or your wheel?

  16. Wonderful ! – well thought out design to handle a rather routine task. I have just one observation to make : with the wheel spinning clockwise and the point of the chisel facing upward, there is a possibility, however small, that the leading edge of the chisel can catch the groove on the periphery of the wheel and lead to a catastrophic event. It would be safer to have the wheel spin anticlockwise, and avoid this.

  17. Great video! Nice light, sound and good camera angles. Also a really nice idea, especially the tightening screw. Subbed for sure! I will watch more of your content to learn and get inspiration. If you are so inclined, check out my fledgling woodworking channel, aNmomadsProjects, and show some support? Cheers.

  18. Это крутая штука,только меня беспокоят что заточка инструмента идёт на зерно наждачной ленты. Ты не боишься что стамеска может воткнуться в этот паз куда зажимается болтом наждачная лента?

  19. Oh man !!!!!!!!!!!!………just trying to make that grinding wheel will take my whole lifetime !!!!!!!!!! Awesome quality of work !!!!!!!!!!!!

  20. I have some constructive criticism if you'd like.
    The video production as well as voice over your work was great. I love it and I definitely want to watch your other videos where you made this stuff.
    My criticism is of this wheel speed, the wheel and mechanism to attach the sandpaper is so awesome I feel dumb for not thinking of it. That's how you know you have it right and simple enough, when people feel dumb for not doing it first.
    But it's spinning way too fast. You are going to lose tempering in the steel. If you can spin that wheel at say 60-100rpm while dripping water on it you'd have a tormek for great price.

  21. Здорово молодец! Разработайте круг для токарного станка с шлифованием на плоскости. 😉
