Had a razor sharp mdf system, gave up on regritting the mdf wheel, made an 8" plywood wheel, glued on 240 grit emery sandpaper, just like this lasting over 50 sharpening and still going without any signs of failing!!!!

Some tips: Cut the sandpaper on an angle instead of butting it square for greater longevity.. When going from right to left and from left to right use consistent pressure and move at the same speed in each direction. It takes some practice but that's how you get even bevels. A perfect angle wont get you far without even strokes. Do one past at a time in each direction to keep your edge in the very center. Stay on the sandpaper side until you raise a burr along the entire edge. Break the burr off and then move to the compound wheel. Use way less compound. A little goes a long way! If you've ground the bevel right and removed the burr, two or three strokes on each side and you'll be able to shave with it.

Great job! I saw on a commercial unit angle markings for height of blade for a given angle of sharpening. Great that your rest is adjustable!

Brilliant idea for beginners in regards to the angle device. Great job!

Super. You addressed the all import aspect of holding the angle. So many show the wheels, which is fine, but do nothing to get the proper angle and hold it. Great job. Just thinking that in lieu of a clamp on the rod to hold the knife a neodymium magnet might work?

Having declared my dissatisfaction with this sharpener last night kzfaq.infoUgkxDcr-y2Pf6xdnrFHrSP7dl9kpKaCozcSQ I thought about the problem some more. It occurred to me that I might be undoing each attempt at achieving a sharp edge by the repeated attempts. So, I tried to clean up the unsatisfactory result by honing with only positions 3 and 4.Miracle!! A really nicely sharpened chef's knife, more than enough to handle my needs. Admittedly, it did not reach professionally sharpened razor-fineness, but it is now significantly sharper than it was. A bout of breaking down carrots convinced me. So, major apologies to the manufacturer, Amazon, and all happy and potential owners! Follow the directions: don't buy it if you have ceramic blades; and don't overwork your knife blade.

Best I have seen yet. Good job dude.

Clearly this system works, and requires less eye-hand coordination than using progressively finer grits on a 2x72.

O wiele za szybkie obroty i nie chłodzone płynem. Lipa.

Simple and perfect

Very cool idea

What kind of board are you using? Thank you

amazing

Very nice! Why did you coat the sand paper with the wax? Is that so the metal filings won't stick to it and that way it will last longer?

WTF !!! One man came up with the idea and implemented it. Then there were 1000 copy cats !!!

Can I order the jig? How much does it cost?

Will try your sandpaper method!! I've got the razor sharp wheels, work great for about 5 knives, then need regritting. Trying different glues, anyone having grit retention problems/ fixes? Razor sharp says should be able to do 100 knives......

А что за материал , из которого сделаны круги МДФ или фанера .?Лента что приклеили на круг на стыковке не отвалится и зачем запилы на соседнем круге ?

Parabéns

Huge amount of detail, but no overview, and hard to follow. Have to give 1/5 Try getting narrators to talk for you: interesting, informative. Good luck

I put a diamond disc over the grinding wheel and mounted the bench grinder sideways so the disc is horizontal. A slope gives me 25 degrees for the chisel or plane iron. Not good health and safety but it is cheap and works.

Видео конечно блеск!!!! Ведь у каждого есть токарный станок и.т.д!!!

16 min vid to sharpen a blade. takes me 5 min max

Is there a commercial jig like this for sale anywhere?

Mission Kitna padta hai bhai rate location

yeah. just to much work. easier ways

احسنت

You have to use polishing paste with polishing pad.its effective more than wood

Why don't you remove the motor from the base then reattach after rotating the motor 180 degrees. This way you can have the switch in front of you. there are several videos on KZfaq

I love it when people love what they're doing, BUT......I think it was a serious mistake to glue the sandpaper to the wheel. It will wear out and then what? A whole better way to do it all for quick and cheap is to get a $50 belt sander at Harbor Freight and use different grit belts that are cheap, easy to change, and can sharpen anything from a mower blade to an axe, to a pair of scissors, to any knife, literally in seconds. I applaud what you did, but there is a much easier way.

но нож всё равно тупой

Not everyone has a lathe

The sound of the knife cutting through the paper sounds as if it was cutting against 100 grit sandpaper/ meaning sharpness doesn't equal smooth cutting or durability? HOMEMADE!! Yup/ In A machine shop, at home.

who the hell has all this much Machenry at there home?

Devi fare scorrere non girare la lama , ti cambia l'angolo di affilatura.
