Topic tags/keywords: sharpen sharpening Hi, New to woodworking here, and very new to hand planes. I bought a couple off eBay that I’ve gotten into good working order, and I purchased a new Stanley SweetHeart with the A2 iron. It takes me forever to get these irons sharp! I’m using some DMT Diamond bench stones, and a Veritas Mk II honing jig. Getting the backs of the planes reliably flat has, in most cases, taken me hours. When doing the primary bevels, I get the burr on the back so I know I’m removing metal, but I can’t seem to get these things sharp in a decent amount of time to actually go work on a project! It’s frustrating. I did buy a DMT extra extra coarse stone in the hopes I can speed up initial bevel formation and back flattening. I also purchased an el cheapo 3000/8000 grit water stone on Amazon. I don’t want to spend more money on sharpening stuff, but with limited free time, I was thinking about getting the Work Sharp WS3000. Something where I can just fire it up, sharpen/hone my iron and go. Maybe I’m being impatient as a novice… Any advice on what I might be doing wrong, or what I could do differently? Some other type of equipment that might work faster for me? Thanks, |

John, frustration in sharpening is normal, but hours is not. Maybe recap what you’re doing. - Are you applying water to the DMTs? Let us know. -- Don't anthropomorphize your handplanes. They hate it when you do that. - OldTools Archive - |

Once you have the basic equipment, sharpening is no longer about those. Any system (oil stones, water stones, scary sharp, diamond plate or machines) can get planes and chisels sharp and all can fail to get them sharp, as well, if not used correctly. It sounds like you have enough equipment to get you going, so then it boils down to technique, process and habits. A couple things to add to Smitty’s points.
You are definitely not alone in the frustration. At my last woodworker’s guild meeting, one of the guys brought up sharpening as something they would like to learn better and about half the group started nodding their heads. Next thing you know, I look over at the guy sitting next to me and he is writing my name down to do a sharpening presentation at next month’s meeting! -- https://www.jtplaneworks.com - In theory, there is no difference between theory and practice.

Here’s a snippet from a blog entry showing the back of my No. 78’s iron. I stopped flattening at picture time.

It seems like we have thousand different ways to sharpen keep trying you’ll find a setup that works for you. -- Aj |

Thanks for the replies! My current DMT stones are extra coarse (they consider it to be like a 220 grit which I never thought was coarse), a coarse, a fine, and an extra fine (1200 grit). I ordered their Extra Extra coarse which is supposed to be like a 120 grit. That will get here Friday. I spritz water on the stones, rub them back and forth until I get a gray swarth, wipe them with an old rag, and repeat. When they stay grayish, I use a Hi Polymer eraser on the stone surface to clean them up (I saw Tommy Mack do that and it works). All the irons have a primary bevel of about 25 degrees. Since they’re new to me, I thought I’d clean up the bevel and flatten the backs. With the back, I only flatten about 1/4” back. On the corners, on all irons, I have spots that don’t look like they’ve been touched! And when I use my jig, often times a new primary bevel begins to form, and it’s often not straight either. I keep checking the jig but it all looks fine… |

Exactly why I started looking into hand planes. I’m making a little end table out of 2×4’s (did I mention I’m a beginner?) and I sanded the top and bottom of the table top. It was noisy, dusty, time-consuming and tedious. I wondered what woodworkers did prior to sanders, and voila! Here I am! |

Most of us plane lovers have a similar story. The nice part is that the first time you get everything working right, hear that “shhhhhick” of a well tuned plane, see gossamer shavings and the surface that results, you’ll be hooked. Can you take some close up pics of the cutting edge of the irons (front and back) and post them? That may help people identify something that could going on and how to help. -- https://www.jtplaneworks.com - In theory, there is no difference between theory and practice. In practice, there is. |

I flatten things on 80 grit sandpaper glued to my tablesaw wing, then when it’s flat, polish to whatever level I want. My way only takes minutes. -- Rick M, http://thewoodknack.blogspot.com/ |

I went through a similar path to you. I started with “scary sharp” followed by trying to use some stones, and flattening/setting bevels took FOREVER. I never really got plane irons/chisels sharp enough, because I would just give up before they were done. SO, I grabbed a Worksharp 3000. I spent an evening sharpening my chisels and plane irons, and was done! I now have VERY sharp chisels and plane irons. I personally have a feeling that if you start with an iron that already has a good primary bevel, you can sharpen it in 10 minutes like many seem to. However, if you’re like me and put your collection together with vintage store finds and ebay junk, setting that primary bevel would otherwise be a MASSIVE undertaking. That said, with the Worksharp you will go through A LOT of coarse sandpaper. Setting primary bevels on some of my blades would go through the lower grits at a 1:1 ratio. Prepare to spend a ton of money on coarse paper when you’re getting started! |

If you are using DMT plates, might try half water and half Simple green. This mixture prevents “rust” on the plates. Abrasive materials are denoted differently in different country they are not the same. 120 grit in the US is not the same as 120 grit in Briton or elsewhere. -- Sawdust and shavings are therapeutic |
#11 posted 03-28-2017 10:15 PM |
I will try the diluted Simple Green. I noticed one of the stones had what appeared to be rust on it which I didn’t think was possible so soon. I had also heard of a person who used Windex with his diamond stones. Same reason? |

I would like to suggest that you don’t try to handplane a surface that has been touched with sandpaper. -- Aj |

I’ve also got an extra coarse DMT stone, use it primarily for flattening water stones. Every now and then I’ll use it on a bevel, but if a back needs a lot of work I do not start with that. It would take forever. I start with 60 grit sandpaper stuck to a piece of polished granite. Then 80 or 120, then the DMT stone, then the 1K water stone. This should not take hours, or one hour, or even half an hour. I’m not a fan of diamond stones. The only reason I own one is for flattening. I know some people hate the work/mess of water stones but I don’t mind, and the fast sharpening makes up for it. Again, this is just me. Everyone has their system and you do what’s best for you. When it comes to flattening backs – I hate it! Not a strong dislike. It’s a real hate. That’s why I start at 60 grit sandpaper. Get this crap over with. Good luck, keep trying methods. You’ll get it. |

From reading your OP I think you should determine whether you have some blades there that are not the best quality or have been mistreated in some way. I’ve bought old Stanley planes with blades that were so warped they were basically unusable. This can be determined quite easily by observing the scratch pattern. If the bottom of the blade is convex, its a hopeless situation. I’ve heard reports of talented people using strategically placed hits with a peen hammer to correct, but I’ve never tried this. If this is the case, you may want to give some thought to a iron/cap upgrade such as Veritas, or even WoodRiver. You will also find a thicker iron is much easier to register on the stone due to the wider bevel surface. So on the sharpening in general, if you’re getting a burr you are on the right track. I would recommend you abandon honing on the primary bevel and hone to a secondary (or micro) bevel instead. This will do two things: decrease your honing time immensely & create a stronger edge. It is quite easy to do, just find the primary bevel and pick up a degree or so. I hollow grind all my irons and chisels I find this makes sharpening easier, too. The most likely issue with a beginner doing freehand is technique. One of those is not locking the wrists and “un” sharpening what’s already sharp due do variations in the honing angle. You may want to consider a simple jig (I recommend the Eclipse=type) to get you started and create some muscle memory. You also need to keep the waterstones perfectly flat. You can use your XX coarse diamond plate for this. Finally, I always finish my honing with 10-12 moderately firm strokes on a leather strop. In no time at all, you’ll be doing quite well. With practice you will be able to rehone and be back to work in less than 2 minutes. Hope this helps. -- Everything is a prototype thats why its one of a kind!! |
