Almost completed rebuild of "old" bench grinder

[tooki]

Painting still in progress. :-)

Bonus points for who knows what the "pink material under the grinder" is.

And it's purpose.

That switch gives me the heebie jeebies. Combined with the lack of understanding you demonstrated in the prior threads, I’d be borderline afraid to use it. I don’t think you really understand the safety implications of motor wiring.

You are entitled to your opinion.

I am indeed. But I'm far from the only one here who thinks you are doing things that could end up with you getting injured or killed. As Zero999 said, we'd rather you have a bruised ego than be in a coffin. Do you not understand this??

As others have said, nothing here is "personal attacks". Nobody is judging you as a person -- ALL of us started off from knowing nothing about electronics!

We are, however, responding to the content of your posts, and that content makes us worry you could injure yourself (or potentially others) with an unsafe rewiring job.

For example, threads like this indicate to us that you do not understand the basics of electricity, since you didn't understand the need to actually connect components, nor the need to insulate things that shouldn't be connected. So when in one of your numerous grinder threads, you express an assumption about a protective ground that's the exact opposite of the way it works, it really indicates you're working on things you do not understand well enough to do safely. That's not a personal attack, it's an invitation to take a step back and fill the gaps in your knowledge before something bad happens.

I will answer your question when the personal attacks stop completely.

What kind of childish attitude is that? Do you always have to be so rude?

You come here asking for help and you are rude to those you are asking?  You argue with the advice you are given. You are told you style of opening multiple threads on the same topic is annoying and clutters the forums and you argue with that too. That is how you ask for help? Sheesh. Some people beg with an attitude like they are the ones giving.

Really, learn some manners or take your attitude elsewhere.

Totally agree with you -- and you and I have had far, far bigger disagreements than this! (But I still ultimately respect you and don't assume you're coming from a place of malice, like the OP here.)

I am somewhat disappointed by that response.  I was hoping you would provide something to help diffuse the tension, but that has done the opposite.

It is not my intention to jump on your head - nor do I see such malice in members here, in general.  However, you seem to be taking offence at any comment which calls your abilities into question.  As I - and others - have said, you have made statements and asked questions that clearly indicate your knowledge is lacking in some areas - and critical safety areas at that.  As we have a wide range of experience and expertise available here, it is this indication that brings concern for your safety and being a group that fully understands many of the non-obvious potential fault conditions that could eventuate, we must, in good conscience, air those concerns.

Your reaction is a classic expression one would associate with the Dunning–Kruger effect - something we have seen here before and which has, in the past (and very likely in the future) garnered the same sort of response that you have received.  It is not a case of being high and mighty on our part - but an honest expression of concern.  Without proper understanding, you could do something that could damage a machine or destroy a home.  It could maim or it could kill.  You may think this melodramatic, but the potential is there.  We can see it.  We had hoped you would come to see it as well.

You talk about respect, but fail to give any to people who have far more knowledge, just because they point out something that you don't like.  You see it as an attack, rather than help - even though they are trying to look out for your well being.

I have no misgivings about my own skill set.  While I first started my journey with electricity at age 8 using a 9V battery, developing over a subsequent period of several decades, I still acknowledge there are many things I do not know.  I have dealt with 415V/240V mains in a domestic environment.  I have worked on battery operated equipment and CRT TVs.  I am still here to relate my tales - but I do not claim to have complete understanding in any way, shape or form ... and if a member here were to call me out on something I was doing, I might be embarrassed - but I would listen.  And I would probably thank them.


In short, our wish for you is simple:  Be safe.

Extremely well said, Brumby.

Participating on EEVblog (and watching a few other great youtubers like bigclive and John Ward) has been an extremely enlightening, educational, and humbling experience. I've learned a ton, and also learned about areas of knowledge ("traps for young players") that I didn't even know existed, and thus would never have thought to ask for help with, and about dangers I would never have thought of, and thus would not have watched out for.

And to be sure, for the most part, if one accepts the advice offered here with an open mind, fellow members will be helpful and help you learn. It does sometimes take a thick skin -- this isn't the most diplomatic forum I've ever used -- but it's all coming from the right place.

Damn. Still replacing a switch? 
The pink stuff is ESD shipping foam, commonly sent with electronics components. To reduce vibration?

One reasonable person among a sea of "anger" challenged individuals.

That is refreshing.

I will answer your question when the personal attacks stop completely.

Tooki, shhhh. Be vewy, vewy quiet. We hunting wabbits.

Oh, I get it now.

Respectful? S.E.* ??!?
Useful, yea, grant that, but no group with Phil Allison as a member could be described in those terms!
 
If you hung around Usenet before the "Eternal September", in the electronics groups you will know who I am talking about, back then calling someone on usenet a pedo because you had a minor difference of opinion was a MILD rebuke, and manufacturing evidence was merely considered doing it properly.

This place is calm, collected and polite in comparison to almost any Usenet group back in the day. 

That job on that grinder is a total cackhander by the way.

Regards, Dan.

You come here asking for help and you are rude to those you are asking?

To be fair, he didn't ask for help. He informed us how LOL it was that the ground wire wasn't even connected to the motor. This prompted unsolicited help.

Then he started a new thread (for secret reasons that might or might not be to bury this stupid mistake and the resultant noise). And the continued and redundant help followed.

Fixit, if you just acknowledged any of the 20 people trying to educate you on the other thread, this probably wouldn't happen. We all make mistakes and as long as you're still breathing, it isn't a big deal.

Oh hells, I'd forgotten Phil, thats a person with some serious issues, I think I had a run in or two with him, Aussie guy I seem to remember with a thing for insulting hifi people by telling them they weren't intelligent enough to understand him?

Walt  Davi(d)son and Jim Thompson come to mind as well, both great guys and hugely helpful but neither tolerate fools.

Jim is/was a great guy but for your own sanity, do not engage on politics unless you are prepared to agree with him and accept there is no other possible opinion.

Then there's PICList's own 'read the datasheet' guy, Olin Lanthrop.

EEVBlog is a fluffy, soft, warm and cosy kindergarten in comparison to usenet.

I am no more than a hobby electronics guy. I am however a licensed electrician. The switch you are using is rated at 15 amps and that is higher than the 4 amp motor. However that switch was not designed to turn on and off a motor. It was designed to turn on a circuit with low draw items or outlets with devices that have their own switching, like a vacuum. But it is not rated to turn on the vacuum.
The problem is that the blade within the switch isn’t designed to deal with the initial current draw on that motor which most definitely will be over 4 amps. And because the blade doesn’t have a spec grade snap action, you can hold the switch in a position that will cause it to be almost making contact. This will do more than shorten the switch life. It becomes a fire hazard.
Tinkering and doing things on your own is fine. However there are easily obtainable correct switching that can be used that will make your home safer. This resi grade switch will arc badly every time the motor is turned on. Over time the switch will either have poor contact and need replacement as the arcing gets more noticeable or it will fuse together one day and you won’t be able to shut it off without pulling the plug. Both options could be avoided.

He actually choose a more appropriate replacement switch in one of his other three threads on this subject and didn't use it.

I am looking forward to his next thread: Splicing a green wire to a brown wire. Which one should go on the left and which one on the right?

Almost completed

So, how far have you got now after the two days? Please provide us with the final result, after teasing us with the first post.

Care to post your angry list?

The person you've just responded to didn't come across as being angry or aggressive.

[fixit7]

No, I do not.

I have found a group of professionals who have already helped me with many of my needs.

I just came by to see what's going on.

Same old angry, unforgiving people.

I will pray for this forum, and I sincerely mean that.

well mr not angry list, care to share what those professionals adviced you on how to connect earth wire and make a proper painting? we are ready to be educated.

[soldar]

I will pray for this forum, and I sincerely mean that.

How do you know you have the right deity? Or will you pray to the deities of each one of us individually? 

I am mostly agnostic/atheistic but I kind of worship money. Will you send me some money?

[Mechatrommer]

there is one out of many noises if you care to look. but if you dont care, even if there are 1000 Gods you will not be able to find a single one. money cannot replace organ failure nor remove anxiety and desperation

Locking this topic, the OP is clearly not open to seeing reason or good advice, there is no need to keep this thread going.

@fixit7 I am sorry that you feel that the conversation here has been hostile, however please understand that those responding here including myself are not angered at you for what you are attempting to do.

This community is full of people that mean you well and are trying to help you see that the decisions you are making on how you alter this device are not only incorrect, but unsafe in a way that can lead to serious injury or even death of you or anyone else that comes along to use your equipment.

From a purely safety point of view, you have removed a safety mechanism from your grinder as it no longer has a simple bump stop, and as grinders are prone to causing some of the most horrific accidents in workshops removal of such a safety device IMO is a very bad idea.

From an electrical point of view, your switch selection leaves much to be desired as mentioned here by quite a few people with far more professional experience then I have.

These comments are not an attack on you, if you still feel they are perhaps you need to take a step back and realise that both machine tools and mains voltage electronics are both lethal and could kill you, and unless you're an expert in both fields (which clearly at this point in time you are not) this community (myself included) advise you to wait until you understand more before making a decision that could ruin your life.
