    Yes, there is a buffing compound that I put on the wheel. Sorry, I did not realize it had been edited out. You can see that the edge of the wheel is white and the compound stick is sitting right below the wheel. You can this compound anywhere buffing wheel are found. I will also put a link in the description where you can buy the compound.

    Make a second MDF wheel the same way you made this one, then on your band saw, using the finest blade you have, make 1/2 inch deep cuts every 2 inches. These relief cuts will help keep your blade cool, this will make more sense as I continue. Mount your new wheel to the opposite side of the grinder as your original sharpening disk. After you go through the finishing stage as you did with the first wheel, apply a light coat of jewelers rouge to your new wheel. This second wheel will be your finishing wheel, used to remove any fine burrs, or wire left on the blade, leaving you with an absolutely perfect edge. If you're concerned about tying up your bench grinder with 2 sharpening disks, pick up a cheap bench grinder from Harbor Freight, Craigslist or even a garage sale, and make it your dedicated sharpening station, completely freeing up your better quality grinder for other operations. This sharpening station is now perfect for sharpening everything from a pocket knife, to a kitchen knife, and even an axe head. You can also unbolt the grinder from it's base, turn it 180 degrees, and reattach it to the base. Now, the switch will be on the front of the grinder, and the top of the wheels will turn away from you.

I live on a budget so my tools aren’t top notch so I watch the experienced people like you and others and at this point I want everything and my biggest purchase is the skil table saw but still want a jointer and planet and a router table too.... you keep making your videos and give me many ideas and dreams of things to make and buy...but disability in Canada don’t pay so much like I make $672 a month so I depend on people like you so when I do get tools I don’t have to replace them every month as they break down or do a terrible job!!!!

      Paw Paw’s WorkShop - Thanks, that is a great idea. Woodworking is a hobby that I picked back up. I love fabricating things. I built race cars, and now building a new Desert Race Truck (2017 Ford Raptor) for next years racing season, which started out as a hobby (that became a runway freight train, because I picked up several major sponsorships this year). However, more money goes out then comes in, a CNC machine would be great, because we are hand building the specialty parts for the truck. My day job is working as an Army civilian employee... after I served 21 years of active duty as a soldier. My Racing Team is called Toy Soldiers Racing. I’ve been seriously considering fabricating a light, hardwood center console, using ash wood because of its strength and is light weight. With all of the technology in modern race vehicles, I thought it would be nice to have a nice hardwood instrument/radio center console as a touch of old school wood components in a world gone mad with Carbon Fiber. Your thoughts?

    Help! Made one of these today. Double thick 1/2" MDF glued together. Used a chisel and sandpaper on a block to get it smooth and round. Charged it with white compound. And all I could do is blunt my knives, which were sharp before. I use stones and a strop to get hair shaving sharp easily. I thought MDF would be an upgrade. I have a variable speed bench grinder and I definitely have some side to side wobble on the wheel. Is this why I am finding blunt knives after doing this?

    • @PawPawsWorkShop
      @PawPawsWorkShop  Рік тому

      The wobble is definitely not good. That means it out of balance or not flat and round. To sharpen the knives, it all about the angle. It should be approximately 20 degree angle.

      It may be possible. The hole in the center must be the same. (Most likely it will be). The guard will likely need to be removed. This potentially poses a safety hazard. Depending on the design of the grinder the wheel may hit the base. Bottom line is you need to try it and see. Please be aware of the safety issues.

Maybe that is still to modern. Tools always evolve. Either evolve with it or stay in the dark ages. Your choice. For me being an old guy, I chose to move into the 21st century. I like technology. It makes our lives easier.

      Hell just grab a beaver by his neck , set his nose on the board, an hit his butt 8 times for board. Now for that half inch center hole 🕳, well that’s tricky, grease your finger up 🙈 you see where I’m going here? Lol

    Why in the world did he make this video? If you have a cnc raise your hand. He said don’t let the knife dig in but he didn’t explain what direction the sharpening wheel needs to be turning to prevent that. If someone gets hurt it will be his fault. Misleading description of the video. Not about how to sharpen but about making a wheel. Thumbs down on this one.

      @@PawPawsWorkShop no problem. Make a video that will be useful to common people. We don’t have cnc machines. Thanks anyway.

      Just grab a jig saw and a drill. You can do it.

      I don’t know what video you watched but he explained it pretty well I thought. He showed the direction of the wheel turning and he showed how to hold a knife so as to not dig into the wheel. Pretty obvious. So if you gave him a thumbs down for that I think you’re kind of a douche or an imbecile
