    Hi Reed, your video in now around 4 years old and it is still the best and most all encompassing video on grinding on youtube. You cover the lot. All the best.

      Thanks. I will have some more videos coming out this year. A bit busy at present, building a house and shop. Now I will finally have some elbow room...

    I have had a worksharp like yours for a while now. I’ve been a woodworker for over half a century and find it the best system ever. You can use diamond discs instead of silicon sandpaper.

    I do have a short clip up on platform sharpening, which will be done over again to make it more complete. I think, as much as anything, it is knowing when to sharpen. This is probably most important when making a finish cut. You can use tools that aren't fresh sharp for roughing, but for all finish cuts, I want fresh off the grinder. I use the CBN wheels ( D Way), and most of the time the 180 grit wheel.

      Thank u brother I learned a lot from this video on grinder safety & not all bench grinders are created equal.👍

    I would still like to know how you sharpen yours. They always seen super sharp.

    Thank you so much for a really great video. Today I ordered a new grinder and CBN wheels to fit. Sadly it is impossible to purchase the Rikon slow speed grinder here in the UK and I even phoned the company only to be told that they were not interested in exporting one to me. Can you perhaps give me any tips on using a faster grinder? I have been sharpening by hand using a 4" grinder with a 2" sanding belt attachment. So difficult to maintain a correct angle etc. I'm now subscribed to your channel and I wish you every success in the future. Thanks once more.....Alan.

      I don't really know about what brands are available over there. I know there are several clubs in the UK. My go to guy over there is Mike Waldt, who is in Whales. Great guy and a bunch of project videos up. Not sure what brand of grinder he uses. Just about any 3/4 hp motor will work, though some are better than others. I think there is a Craft Supplies store over there, but they are not the same as the one here in the US. Have fun!

    What was that last jig? Thanks for the great info and why didn't you put the robo rest on this video?

      +Christopher Ashcraft This goes back to before I had the robo rest finalized. I will have another platform sharpening clip up soon, hopefully by the end of this week.

    Reed are your Baldor grinders slow speed? I have an old cheap Woodcraft Model 144290 slow speed grinder. It takes a while for it to come up to speed and has some significant runout. I'm a production turner and find myself constantly going to the grinder to sharpen my tools. I'm looking for an upgrade. Thoughts? Many Thanks - Skip

    • @robohippy

      My Baldor grinders are slow speed. Best substitute I can think of, and at the best price is the 1 hp Rikon grinder. While it doesn't quite match the Baldor for smoothness, it is a match in power, and I think the price, if you can get it on sale is about $220 or so. I have 2 of them, and they come up to full speed as fast as the Baldor. I had to put a 3/4 inch piece of plywood under the Wolverine base to get it to height. I tool the electric light off as it isn't bright enough, and doesn't reach the grinder platform. Of course, the grinder platform that comes with it is junk. I did have to add a spacer or two to get the 1 1/2 inch wide CBN wheels away from the wheel housing. I do prefer to keep that on. Main reason is the dust from grinding can float around the shop like wood dust does. Strange but true. You can order the Rikon through pretty much any big box store. Best price on line that you can find might be Ken Rizza of Woodturner's Wonders. His come without the wheel guards. Oh, I take the rubber feet off the bottom of the grinder and bolt it to plywood.
      Side note, if you can learn to sharpen with a platform, it is a lot faster than using a jig. I have sold out on my grinder platforms, but sent all parts and pieces, and schematics to some one who said, 'some time after the first quarter of 2021.'

      @@robohippy Thanks so much for the quick response Reed. I have seen the free hand sharpening video by Mike Mahoney. I have the Wolverine jig setup but would prefer to sharpen free hand. Looks like Rikon from Woodturner Wonders is the answer. Thanks for the quick response. Your videos are excellent!

    • @robohippy
      @robohippy  3 ปีที่แล้ว

      @@skipproctor8979 The best thing about the free hand sharpening is that it is faster than using a jig. Only set up time is in changing the angle of the platform, which is why I made mine. I know I cover it in my sharpening videos some where. Biggest secret to it is that every thing you do when platform sharpening is exactly what you do when turning. Since I started using the 40/40 grind, I never use a swept back gouge any more since the 40/40 does cut better except for trying to go through the transition and across the bottom of a bowl. I am sold out of my platforms, but they should be coming out by some one else 'after the first quarter of 2021.

    Sharp is better! Razor sharp is the best!

    • @robohippy
      @robohippy  6 ปีที่แล้ว

      Razor sharp is better for bench chisels, carving chisels, hand planes, and in most situations for the skew chisel. For some punky woods, and woods that are more prone to tear out, they work fine for finish cuts. The razor edge is worthless for heavy roughing in most woods because they go dull so quickly. I can remove more wood in an hour of turning than you could in a few days with the above mentioned tools. Get 5,000 or so bowls, in all sorts of wood, under your belt, and perhaps you will understand...

      I am 76 years old been in wood working all my life! I do agree with you on a lot of your shows. BUT you are full of CHIT when you say a dull cutter is better than a sharp one! I have been sharpening tools of all kind all my life and I have never wanted to work with a dull tool they are very dangerous. You should not miss lead people that doesn't know u could get someone hurt.

    • @robohippy

      Well Sam, I am 67, and have been a too-aholic for most of my life. You still have some things to learn. My tools are NEVER dull. Just because I use a 180 grit wheel for most of what I cut, that does not make my tools dull. If there was a safety issue with this type of sharpening, then none of the big name turners would be sharpening the same way I do. I can slice myself easily on that 180 grit edge. Yes, dull tools are dangerous, but your 'opinion' is not shared by most of the people who have forgotten more than either you or I will ever learn.
