Nice build. We shared this video on our homemade tools forum this week 😎

Love the blue colour. Not so good to use the edge of the wheel if you have a few drills to do. It would be nice to be able to cool the drill in liquid if it gets hot. Very lovely video all the same.

There is one more complicated type to make but it works better(you can adjust all angles and even grind a split point) and that is Lisle grinder.Abom and mr pete have dissasembled one and you can find pictures in manuals.
But you need advanced machines for it like lathe and milling machine.Still it would be cool to see one built for bench grinder.

Wow, nice video, but home made? That's quite the machine shop and processing. The inclinometer was a cool touch. I suspect that building this is well beyond most home shops.

Great video, but don't use the side of A grinding wheel. (Only the face narrow part)
They can explode.

Great project, if you looking for a project, but you can buy a commercial one for less than $20, I believe.

Mekanizmanın merkez kaç şeklinde dönmesi daha verimli olacaktır kesme işleminde matkabın sırt kısmı dolu olduğundan sürtünme daha fazla olacaktır ve buda ısıya neden olur.sağlıklı bir kesme gerçekleşmez  emeğine sağlık teşekkürler.

Good job,I like it!

С использованием такого принципа поворота теоретически затыловка отсутствует. Неудачный ракурс для заточенного сверла не позволяет увидеть это. Но результат сверления, когда металл крошится, а не снимается стружкой, косвенно подтверждает этот вывод.

с такой перемычкой хер оно будет сверлить без расверловки

Amigo,  parabéns  esse torço é de mais.
Faça  pra vender.

Por que só se faaz teste com brocas de mais de 10 milimetros?

Boa ideia ese gabarito para afiar brocas

Ten čap na ktorom sa robí pohyb pri brúsenie má mať sklon. Vrták na tom to prípravku je zle nabruseny, nevrtá, frezuje.

muy buena explicacion y buen invento, pero siempre videos con brocas grandes que tal si lo haces con una broca de 1 mm seria digno de ver

Сделано неправильно нет наклона поворотной стойки ,для того чтобы получалась затыловка

But why when you can buy one for like $10?

You look expert

Boa tarde vc faz essa ferramenta para vender

Never buff on the side of the wheel
