Rough Grinding A Plane Iron • Complete Sharpening Series Video 2
ฝัง
- เผยแพร่เมื่อ 4 ต.ค. 2024
- AskWoodMan.com/ This is the second video in my complete sharpening series. In this series I will use the following tools and machines: Makita 9820 electric water stone with an after market sharpening jig, Bosch belt sander, Porter Cable belt sander, Mitutoyo combination square, General Sharpening Jig, DMT Diamond Stones, and various chisels, plane irons and scrapers.
This second video shows how to rough grind a plane iron on the Makita Sharpening Stone. When a bevel is very far from 25 degrees, it is important to re-establish the edge BEFORE sharpening on the diamond stones. This will also lengthen the life of your diamond stones because the vast majority of the steel removed for bevel reset is done on the electric water stone.
In this video I use the 120 grit course stone green wheel to get the bevel as close as possible to the original 25 degrees. For this process I use an after market jig to hold the plane iron in place. This jig is only available at Highland Woodworking. NOTE: I will also show how to rough grind chisels on a belt sander in later videos for those that do not own a Makita 9802-2.
This video is just one in the series where Allan Little shows all his sharpening techniques that he has refined in the last 25 plus years to attain the sharpest chisels, plane irons and scrapers. This series will show not only how to hone and sharpen using the diamond stones, but also how to grind on the Makita 9820 course wheel as well as belt sanders. This series ends with chisels, plane irons and scraper demonstrations.

Great video. Great information. I really got a chuckle when you said "We're not sending this thing into space. It's not NASA." I immediately thought of my father and the fond memories I had of helping him out when I was a young lad. His favorite idiom he used when things didn't always turn out exactly as he wanted was "We're not building a Swiss watch here."
Thank you young man. Your efforts are appreciated more than you know.
Thanks Roger. Not everyone appreciates my sense of humor. So thanks for taking your time to write me such a nice note, and thanks for watching. Keep in touch. Allan
Don't be embarrassed Alan, it just means that you actually USE your tools. Good on ya, mate!
That machine is the Makita 9820-2. I use it primarily for quickly putting a fresh edge on my planer and jointer knives. I have a complete video series on my channel about using it. Last week I was milling some very tough hard maple that had some figure in it, and wanted perfect surfaces with no blowout ,so I pulled and sharpened my planer knives 3 times and my jointer knives twice in one day. It is a really great machine. Allan
@askwoodman You did a pretty good job with that flash intro to your videos.
Regarding the video, I've been looking for years to find out how to sharpen tools. And a full length video like this is really useful -- details like emphasizing squareness and that extra jig are critical. Thanks again.
I bought one of those grinders about 30 years ago for about $30 and never could figure it out. Today I dug it out, cleaned it up, unfroze the bearing and sharpened a couple of my stanley #4 blades. I think the wheel is a little high on the outside edge of the wheel. I have no way to dress it, so I just went back and forth over the high spot. The first blade took about an hour to get right. The second took about 15 minutes. There's a bit of a learning curve. The bevel was easy. Getting the edge square to the side was the hard part. I finally set the blade in the jig at an angle and used a magic marker on the bevel to see where I was grinding.I'm gonna try doing my electric hand plane blades next. Thanks..
Very exciting to see new videos from you!
That bevel angle just creeps up after many sharpenings and it is really shocking to see how far off it can get. Thanks for watching. Allan
I have the same grinder. I wish I had that jig you have to hold the blades.
@dzzz78 No it is not. I just try to be consistent and get everything as close as possible. And before I reground the bevels these knives were still cutting quite well because of the clean facet produced on the diamond stones. But when knives start getting 7, 10, 15 degrees away from 25 degrees it is time to address it.
@wdworking Thank you. I just wish my computer skills matched my woodworking skills. I could go straight to the top baby! On second thought, I like where I am except for my computer skills.
@spelunkerd Thanks for watching. I will get back to you soon about the Fein blade replacement conversation we had. I think the whole sharpening series may be 20 videos or more. I just really want to share a minimalist technique I have developed over 25 years. I want to help woodworkers get past that most irritating block to get work done, namely how do I put a super sharp, durable edge on a knife quickly without spending a lot of money.
This thing is retail at $600 after tax right now for a plastic case with a simple motor probably worth $30. What a crazy world we live in.
Don't complain to me. I don't work for Makita.
Haha I thought I was the only one left in america who still used an old horizonal sharpener.mine was used in the 80s when I bought it for $8.00.it throws water every where , you need to wear a wet suit, needless to say I try to sharpen every chisel and iron at the same time.on ly draw back is it wont do very short chisels.I like the wood degree guage you made , thanks
Edad Martin I have a whole series about that using that machine for planer/jointer knives. It is a mess. In the series you can see the classy garbage bag I wear to keep the water off me.
It was a fair bit off the angle!! I'm a site carpenter, my planes and chisels take a beating so I'm sharpening them all the time, some of the angles I've had on my blades are ridiculous! I can't carry my all my equipment, just my diamond steel like the ones you have so I'm free hand sharpening my edge all the time, it just creeps higher and higher!!
Is a degree really that much of a difference in how the blade performs ?
the sharpening system used sounds different from others I've heard in sharpening videos. This one is made where?
1000 is what comes with it. This is a 120 alternate wheel. They also make a 60 and a 6000.
Where did you get the 120 grit wheel? I can only find 60 and 1000.
@@steadyeddie7453 Unfortunately Makita discontinued that 120 wheel. A real shame because that green silicone carbide really cuts fast.
@@AskWoodManSo odd that they make a 60 grit and 1000 grit only now. Sharpening is all about progressively working up the grits starting with chipped edges to honing and polishing. Even more odd that there isn't an aftermarket version of these wheels. Thanks for the quick response. Cheers
Its now 2022, and I cant find any replacement sharpening wheels besides 60 grit and 1000 grit. Where did you get your 120 grit wheel? Are there other grits available besides these three? Thanks for the video.
thanks
Was anyone else yelling 'TURN THE THE TAP OFF!' at the end?
XD
Thank you. Exactly what I was looking for. What us that grinder called if I wanted to buy one?
My plane iron somehow has a taper on the left side. I spent hours trying to square the edge by hand.
Stupid thing is still not square.
I have found that the squareness of the grind is not that important and I tend not to waste metal chasing squareness on chisels I buy here and there. As I sharpen unsquare chisels I will eventually square them. Degree of bevel is the more important thing to get right.
Hi! I'm wondering if you have any recommendations for sharpening new garden spades that come without an edge. We sharpen about 200 spades a year before we sell them, using a regular bench grinder freehand with a coarse stone. The edges are curved so I don't think a jig would work. I'm wondering if a wet grinder would be better, but we're taking off a lot of metal and I'm not sure if it would be as fast or how often we'd have to replace the stone. Anyone's recommendations are welcome.
I am an avid gardener and i sharpen my shovels with an angle grinder and a 60 grit disc on a rubber backing plate. Works like a dream. Write me at askwoodman@gmail.com and I will send you pictures of the setup. Allan
Was the after market sharpening jig used with the Makita 9820 commercially available or did you fabricate it? Are there any references to the jig availability/fabrication elsewhere on your site? Great video.
+Bill Maille Bill Highland Woodworking still sells that aftermarket jig. www.highlandwoodworking.com/dual-usehandtooljig.aspx
Allan..just got a 9820 off Ebay and excited to try it out this weekend. Is the fluid in the reservoir pure water or the 50/50 w/ Simple Green?
Hot water in the reservoir, but I will the Simple Green mix to clean the stone if I have fouled it with WD40 from oiling the cast iron tool holder.
Where can I get the jig for holding the blade? I bought my sharpener used and it didn’t come with one. Nor can I find where I can purchase one.

AskWoodMan thank you very much. Most helpful and your reply was very quick! Fred
@@AskWoodMan I know that this response was from 5 years ago, but I just talked to Highland and they said they don't carry that jig anymore. Bummer, would have been just what I needed!
what's the grit of the wheel that comes with this sharpener?
I realize you probably have your answer, but for folks just reading these comments, the 9820-2 comes with a 1000 grit wheel. I see 60 and 1000 grit wheels are available but haven't found anything inbetween. I would love one in the 220-320 range.
