Trouble at mill

I see a lot of questionable advice and methods from the 'teachers' on You Tube. This one took the biscuit tonight.

See if you can predict the outcome. I did, and hid behind the sofa as I watched.

And his use of the ruler just grinds my gears. Its so so wrong, in so many ways.

Steve

And so easily preventable too. Really stupid for a supposedly experienced machinist.

He'll get that scale a little too close to the cutter one day and then he'll be wearing it or it will be embedded in the drywall. An old paintbrush does a much better job of cleaning chips anyway. JD

Yes Steve, that was a new way to use a ruler, at least to me. I too would have taken cover if I was in that workshop.

Changing the subject a bit ( apologies to OP) i noticed that he cut a circular indent in the steel

Probably a dead silly question but:

Forget clamping or material thickness for now - but how would one cut ,say, a 30mm diam sinking of only a couple of mm in the face of a flat steel. Would the method be to clamp in a faceplate & cut on a lathe or is there a way to get a circular shape that is not very deep with a non cad mill when the diameter exceeds end mill cutter diam

For example I might want to use the indent to locate something in a precise position but not have a hole right through

Sam,

Short answer is to use a rotary table.

For anyone who want to watch this and still retain a life just go to the 13 minute bit.

I had to smile when he started and said his machine had lost connection with the controller, then mentioned he was using a laptop.

DUH ??? Laptops have built in power saving, everybody except one knows this.

I do admire the fact that the video came first over hitting the E-Stop

Sam, as above a rotary table or if you have one a boring and facing head, even a plain boring head if you mark out and mill close to the lines then bore.

Good example of recutting swarf, why not just use the cutting oil or a weak air jet to remove the swarf off the job?

Quite so. The same is true of forums, including this one.

There is a great mystery contained in YouTube....Why do middle-aged men desire to post their ineptitude for the world to see?.......

Only the other evening I was sat watching a mid 40's man with a large blob of melted and bubbling plastic stuck to the front of his trousers, who kept up a constant inane chatter like a fountain pen salesman at the Ideal Home Exhibition, interspaced with screams of agony...........WHY, I want to know, did he then post his stupidity for all the world to witness...?

I have noticed some similarities among these people........They are often heavy jowled and apparently lacking in any tangible vestige of charm or attractiveness...they tend to wear 'plonker caps' like in the OP's link and frequently wear shell suits left over from when they were young in the 80's. Their worst feature is their need to constantly chatter rubbish, often about other stuff than the matter in hand, and this, I think, is the 'secret'.......They are so basically lonely, unloved and ignored that they are impelled to post their frantic attempts to gain attention and aceptance whatever the cost.

UK's 'myfordboy' videos show how it should and could be done, but people constantly enquire why he never speaks. It never seems to occur to them that he is too busy 'doing' to chat about the weather or the political situation or the bird song which graces most of his vids.....The whole YouTube thing is a bit weird!

Thanks

So obvious now you have said it that I feel a bit !!!!!!!!!

I think we all know who the newby is by now

No problem, Sam

It's only 'obvious' when you've done it.

What drives people to publicise their ineptitude? The same thing that drives them to post such things on Facebook, Twitter etc.

A recent U3A National Newsletter carried a short article, by someone with a sense of humour, who decided (so he says) to participate in Twitter (or maybe Facebook - it matters not) without the aid of the Internet. So he went down th street, greeting strangers and telling them what he had for breakfast, and how his journey to town had been. He concluded by saying that he now has four followers.

Two policemen, a private investigator, and a psychologist!

What drives people to publicise their ineptitude?

Well, the same thing that makes them become politicians, I suppose.

Tim

Yeah, +1 Tim, but that's too long a discussion to get into...

The internet is a bit like the published word. Once out there and it's for all to see for ever. Doesn't matter if it's wrong, the more people that post on it makes it right.

Classic one is where on the Jose Rodriguez Hobbing video where he get Pi wrong - repeatedly and therefore all his calculations are wrong.

Popped a comment on this guys YouTube site re the use of his rule; this is what his reply was

'Yes I usually use a cheep paint brush. I hate air on the machine blowing swarf around isn't a good thing either. I usually use a brush and vacuum. I've been pretty lucky in my 40+ year career with some of the bonehead things I've done. I have never had any cuts or injury's bad enough for stitches not for the lack of trying haha...

Playing Devils advocate here :-

Yes he messed up. - But he at least had the bottle to still post the video when he could have chosen not to. Presumably he did this to show others what NOT to do.

As the saying goes. "We all learn from our mistakes." Well now thanks to youtube, forum sites and other types of user media platforms we can all learn from other peoples mistakes without the penalty of actually making that mistake ourselves.

Most of us here are hobbyists and do make mistakes. I personally feel it's good when we 'fess up' to them for the above reasons.

With the notable exception of useful stuff like Prof. J. Hugel's notes about drill sharpening

See the Potts thread.

I totally agree with Nick-G. One of the reasons I seldom use this forum is my inability to compete with all the "perfect" people that inhabit the site.
