How many CNC karma points did I lose

[Julien]

…by doing this ?

I confess. The 8mm circular pocket I milled in a piece I was working on was a hair too shallow, I had already taken it off the wasteboard, so I grabbed the 8mm square endmill and did this. It worked fine but it felt like the Gods of CNC were rolling their giant eyes the whole time

I’m sorry, we’ll have to take the nameplate from your Shapeoko to make up for this grave and unforgivable sin.

Also I really need to find some solution for similar problems. I’m in a situation now where I need to mill a bunch of holes to be slightly wider than they were before.

Is there such a thing as a threaded dowel pin?

I could quote @Vince.Fab in your defence;

"Anything is a drill if you push it hard enough "

[fenrus (Arjan van de Ven)]

the way you solve the “center finding issue” for drilling bigger is one of these:

(there are many variations on the thing I linked, all over the price/quality spectrum, this was just first amazon found)

this should have been designed correctly the first time…your lucky I’m not in charge at carbide you would be fired sir…I have to do this all the time. Your just lucky you can easily find metric drill bits.

@Moded1952 - surely you don’t mean this treatment for @Julien…with the breaking of the end mills too?

[Able (Donovan)]

No shame in saving time as long as you got the results you were looking for. In wood you can get away with using a square end mill in a hand drill fairly easy. Aluminum with a big mill however might be a challenge and require a drill press.

When it comes to aluminum projects with several precise holes I would rather spot drill on the cnc and finish on the drill press rather than watch my machine helix forever while I sit watching hoping nothing goes south.

What’s that old saying? Something like “…the measure of a good craftsman is how well he fixes his mistakes”.

I must be REALLY, REALLY good. HaHa

@Julien

so I grabbed the 8mm square endmill and did this

Maybe it’ll convince @RichCournoyer that it’s ok when someone calls it a “bit”.

[fenrus (Arjan van de Ven)]

well the endmill went into the portable manual CNC unit

[RichCournoyer (Richard Cournoyer)]

I prefer ROUND End MIlls (endmills) with Flat Bottoms…not to be confused with Fat Bottom Girls…And it’ll never happen Neil…never.

Wow, that takes me back!

Karma points are like Attaboys; when you lose them you lose them all!
