Ben, I just had a vision of how you walk around in your workshop, enjoying life, taking in the wonderful scent of woodworking. You grab your favourite chisel to work in peace on the finer details of a project close to your heart.. Just to realise that the chisel is dull as a butterknife. You don't want to lose temper or inspiration so you simply pull out your second favourite. Just to realise that "someone" has molested your perfect sharpened angle in a massacre of an attempt to sharpen it for you. "No worries" you think, you have a good day. You will re do it. You pull out the stone of choice, just to realise that it more resembles a wild rollercoaster ride than a flat surface. You take a quick glance in dismay around the workshop and to your horror sees a diamond stone submerged in water. Your beloved tools corroded in a pair of sweaty hands. A young kid sharpening with a course file and the unmistakable sound of a grinding wheel. And the truth dawns on you. Your bit of heaven is infested with demons from the lower depths of hell..

sharp tools = sharp work, this is the most important part to all guitar building , its all in the preparation, really cool topic to cover

@CrimsonCustomGuitars 9 лет назад

I couldn't agree more! Without sharp tools you may so well just forget building a top quality guitar, or piece of furniture for that matter!

@Beargrizzly76 9 лет назад

I absolutely love sharpening my chisels! It's therapeutic for sure. Only recently, I was sat on my garden bench at 6:30am, cup of tea not far away, using my oil stone to sharpen my AI chisel...a great way to start the day. It's a bit odd but I love the smell of the 3-in-1 oil too! I finish up with the veritas honing compound which to me, is the mutts nuts. Seriously, it never fails to bring up a super polished finish.

@walterrider1612 9 лет назад

thank you Ben. yup heat will destroy the hardness of tools so be careful

@WoodesosGuitarMods 9 лет назад

Great video, thanks for posting. I learned a lot. Even as a long time hobby wood-worker, sharpening is just something I've avoided. I think I'm gonna try to revive some old tools:-)

@michaelvalkevich6085 9 лет назад

Great series, Ben! Very informative and it is interesting to hear your comments about your long-held opinions. I think we all have those ...

@clehman67 6 лет назад

Good video! I'm thinking the reason the oil stone is cutting so well is the chisel is a softer high carbon steel (i.e. O1). Harder steels such as A2 and Chrome Manganese (Cr-Mn) benefit from diamond plates and water stones. All of them will work, but some stones will take longer. The Popular Woodworking channel has a video about Carl Bilderback who does what he called "oilstone dance" which allowed him to keep his oil stones pretty flat after 20-some years of use. Might be worth a look if you haven't already seen it.

@blackfender100 8 лет назад

Thank you so much I learned so much here.I just went out to my garage and got 2 pathetic wood chisels so sharp it's scary.The grinding wheel method worked great kept me on the perfect angle on the oil stone.Thanks again Ben

@CrimsonCustomGuitars 8 лет назад

My pleasure, once you have the knack of sharpening effectively, whatever method you choose, it opens up so many possibilities for improved work in almost every imaginable part of woodworking and many other crafts to boot. Thanks for watching, I appreciate your support.

@nigelsmith858 9 лет назад

Thanks Ben I think I'm really going to enjoy this series. Its ironic you start off with the same method I already use for sharpening chisels. The only difference is I use the white norton grinding wheels which come in different grits for the grind and then a 1000 then 5000 waterstone freehand followed by a strop. Same results. I like the hollow grind on chisels makes it much faster to get the cutting edge. I do use a honing guide for my plate irons though, I find them much harder to do freehand especially the wider irons from a 6 or 7.

@boozoochavis7506 5 лет назад

Can always tell when any stone is working because the lube is moving swarf and turning black. If the colors change it has to be moving some metal around some place! Those work great for honing and polishing more than anything else.

Camera thoughts: The thing with the prime camera lens you said you are using is that it is very bright, which is why it is good and sharp. But unfortunately that also means it has quite a narrow focal plane (ooh planes) at the brighter aperture setting which causes your close up focus difficulty. I'm not certain of your settings when recording but a smaller aperture (larger f number like 9 instead of 2) would give a wider focal plane (ooh planes) which should keep the whole bench in focus. That is assuming the camera isn't overriding that automatically. Photographers use these bright high apertures (2 or smaller number) for exactly this reason - to narrowly show an object in focus, like a persons face, and blur the background and foreground deliberately. Not quite what you were wanting to learn about but meh :)

@stefanwolf88 9 лет назад

Nice washita stone /around 600 grit ANSI standard - around 15 microns/ - paired with a Norton coarse/fine india /90-30 microns/ and Norton translucent arkansas /around 5 microns/ makes dependable sharpening set. Your videos are really good. Have a nice day.

@trackie1957 8 лет назад

I use a block of hard maple for my stropping - rub it with compound and use it the way you use the leather. I think it has the advantage that the surface doesn't 'give' as much so the flatness is better preserved. The softer leather could produce a slight radius at the edge, but maybe the real reason is that I don't have a bit of leather. Either way, the wood works quite well and is very flat. Love your videos, btw.

@CrimsonCustomGuitars 8 лет назад

Thanks for your support! I kind of feel the same about the strop, I love mine but worry about that softness.. I'll do a vid comparing them in this series. Btw if you ever order anything from the store put a note on the order and I will make and send a leather strop for you to try foc. And you can let me know what you think once you've had a go..

@pmckinlay653 8 лет назад

Don't grind all the way to the edge- You get all the advantages of hollow grinding without the ragged edge. That advice came from Vic Tesolin :-)

@gabrielemaggioni5521 9 лет назад

Hi Ben, if you don't like the smell of mineral or synthetic oil, try Johnson's baby... It also leaves your hands skin much smoother ;)

@MrBomccorkle 9 лет назад

hey ben! I actually have an 8" grinder that's a low rpm with a water drip especially made for sharpening chisels and gouges. I can't remember the brand or where I bought it but it does work a charm and slays the standard bench grinder on getting a good edge. I think a bit of Google should steer you along

@rodneyhowe4486 9 лет назад

Really liking these sharpening vids....I use white spirit as a lubricant on oil stones which is much thinner and cleaner to use.

@CrimsonCustomGuitars 9 лет назад

Good tip!

@MrBomccorkle 9 лет назад

also, to add. to make sure I am keeping a good proper angle on my tools I color the ground area with a sharpie to have a good visual reference

@pmckinlay653 7 лет назад

I'm waiting on a soft/black combination oilstone from Natural Whetstones. I'll let you know how that goes!

@wolflahti412 9 лет назад

Flattening the back of a chisel is an essential first step before you try sharpening/honing a bevel.

@transcendcraft304 8 лет назад

did you figure out the angle that luthier Tom secretly sharpens his chisel at? The "Right Angle " is as much a point of conjecture as the world sharpening method lol

@willford8475 9 лет назад

I have a bunch of Robert Sorby chisels that look identical to that one.

@mixolydian2010 9 лет назад

I have a friend who destroys his bridge saddles and pickups with acidic sweat its weird I don't. Cheers for the video.

@tinman1955 7 лет назад

Arkansas stones rock.

@loloaqici82qb4ipp 9 лет назад

There are barrier creams available to tackle the rusty fingerprint syndrome. I don't have any brand names but ask someone who works in engineering metrology and they should be able to recommend one.

@jrmakawoody 9 лет назад

food grade mineral oil is used by many on oil stones

@RafaelHe 3 года назад

Did you end up adopting the oilstone in your sharpening routine? It actually looked like a Washita stone to me, a type of Arkansas stone.

@CrimsonCustomGuitars 3 года назад

I do use an oil stone quite regularly now days, amusingly enough a white Arkansas stone for the most part. a great stone! B

@esa062 9 лет назад

The ability to discover that you have been wrong and change your mind is a sign of intelligence.

@kearnsguitars2236 7 лет назад

I found some stones at an estate sale, how can I tell if they are oil or water?

@lambofwrath95 7 лет назад

Would the youtuber you are talking about perhaps be named Paul Sellers by any chance?

@rodneyhowe4486 9 лет назад

I have an old scalloped "india norton" oilstone which is hollowed, how could i re-surface it flat again????????

@CrimsonCustomGuitars 9 лет назад

A diamond plate or rough sand paper on a thick glass plate. I've even run stones through a wide belt sander just before changing the paper out, though that felt very very naughty ;)

+Crimson Custom Guitars Im not sure if hes eating fish sticks because hes lonely and just moved here... lmfao

@NeilTheDruid 9 лет назад

That corrosive sweat nonsense is real. I tried to take the pickups out of one of my guitars a while ago. Took about half an hour longer than it should have.

@ianbcnp 9 лет назад

Some swine has persuaded me to spend far too much money on a Robert Sorby Pro Edge. I have high hopes! Just hoping Yandles get around to dropping me an email to tell me it's on its way soon.

@CrimsonCustomGuitars 9 лет назад

Who was that? Quick, get the pitchforks :) you will love it, I guarantee!

@ianbcnp 9 лет назад

I've been pondering whether to get one for a while. I enjoy woodturning in my spare time. I can sharpen a flat chisel, plane blade or axe to a razor finish on an oilstone and strop but getting consistently good results on curved gouges using a 6" wheel is something I've really struggled with - particularly as I'm not spending 8 hours a day at it. I just want to come home from work, pick up a sharp tool and get turning so I'm hoping the Pro Edge will hit the spot. Turning hardwoods can take an edge off a tool frighteningly quickly so I'd really like to be able to put it back on equally quickly. Your unboxing enthusiasm just pushed me over the edge :-) I also wonder if a hollow grind (particularly the relatively harsh hollow grind from a 6" wheel) is ideal for skews and parting tools (or anything else for that matter). I can't help thinking a flat grind should be somehow better. I'll let you know in a few days if I can drag myself away from the lathe for long enough to type!

@jeroenverbeeck7925 9 лет назад

that intro :p

@ayeitsme6988 9 лет назад

bit too much movement on your oilstone. i only polish the front edge of the chisel which is much faster.

@ianc4901 9 лет назад

It's hard to believe, given your experience that this is the first time you have used an oil stone. Most oil stones are double sided, it looks like you are using the fine side on that stone, I can see a thin, lighter coloured section.

@CrimsonCustomGuitars 9 лет назад

Ian Clarke premium ones are cut raw from the ground and the 2 sided ones are manufactured.. I've used this for years for scrapers but little else..

@jwhite46151 7 лет назад

I know this is a long while after your response but I just stumbled across your videos. I thought it would be helpful for you to know that natural Arkansas stones are routinely sold as combination stones from reputable quarries. They are made by laminating two separate densities of stone via an adhesive. While gluing two rocks together may technically be manufacturing they are still natural stone. I make my living from working wood and have used them for maintaining my edge while in the work for many years. One stone on the bench; quick, clean, and easy. Good on you for putting a chisel to yours.

@ianbcnp 9 лет назад

Blimey - you've been censored, expurgated, de-belched! Are you trying to be taken seriously or something? It made me laugh - but you have a long way to go before you can compete with my 17 year old daughter's window rattlers!
