Re: SPEAKIN BOUT FUSES

 

Excellent information.

Another potential point for a break in the grounding of a water pipe is when/where the pipe enters and leaves a water heater. To reduce corrosion, water heaters often employ dielectric fittings where the water line enters and leaves the heater. Thus, the potential grounding of the hot water line exiting the heater becomes electrically isolated from the cold water line entering the heater. While the hot water line should never be used for a ground connection, there is always someone who thinks this would be OK.

There are a couple of types of breakers in a nutshell thermal trip and
magnetic trip.

Both have specific purposes and characteristics.

They do not however have arc over like fuses do. This is VERY carefully
designed into them prevent this very type of failure.

They do extreme testing during manufacturing process to insure this
cannot happen. The stress testing for arc far exceeds its rating.

I have worked as a Controls Engineer for over 35 years and actually
worked for Schneider Electric at their plant that makes breakers I can
tell you it would amaze you how much they put them through in testing.
It is scary to watch sometimes!

Also you always want to break the hot side of a circuit NEVER break the
neutral. That is a violation of both NEC,CE, and NFPA regulations along
with UL. You also NEVER should tie a ground wire from anything to a
water pipe. I know they used to do this. BUT it is no longer allowed
with good reason. THINK about it. Someone comes along and replaces a
section of your metal pipe with plastic. This just happens to be between
your ground connection and actual point the pipes leave the building and
make contact with ground. You just lost your ground. That is WHY it is
NOT allowed. Same as you always tie one side of the secondary single
phase step-down transformer to chassis ground UN-fused and use it as
neutral.

If you put in sub panels AKA secondary panels a ground rod may be
required depending on the circumstances at the panel. Better safe than
sorry even if its not.

It is never too expensive to be safe. Installing ground fault breakers
in a panel are cheaper than plugs at point of use and protect the entire
load of that circuit. You can even get the ones that protect for arc
flash too but they can be a pain with larger electric motors especially
brush types. The sometimes see the motor starting as a fault and will
trip. But you can use a dedicated circuit if all else fails for your
older compressors and things like that.

VAC 3 PHASE EVERY YEAR.
Re: SPEAKIN BOUT FUSES

 

That is all correct info including what the codes say from the other Charles ("Cowboy1764).? Also, if using multiphase, breakers must be ganged so that if one trips, they all go off.? Of course, if using fuses (not recommended for that, perhaps no longer allowed, I'm not sure, I'm out of date) you don't get that protection.? I doubt anybody is running their mini-lathe on 3 phase,? But your home is very likely a 120/240 service with a ganged set of breakers for the mains power coming to the house.? (If not, you should probably have somebody fix that.)

Re: Free-standing Splashguard?

Dear Dave,

Just a thought.
I enlarged the splash guard, moving it both further back and extending it slightly, by using part of the case from an old desktop PC case. I also made mine easier to remove. L shaped slots. (Similar metal thickness.)
It might be worth considering that route. Fortunately for me, the metal PC cover was a very good match for the Chester(UK) 7 x 12 colours at that time.?

Regards,

David (UK)?

It means that within the listed voltages, the breaker or fuse will create a open circuit fast enough that's likely to protect the circuit.? Under very high voltage, an arc can form that jumps the gap. On YouTube, a content creator named Electoboom, just demonstrated this behavior.?

The splashguard on my 7x16 is always getting in the way. It seems a free-standing splashguard 18" wide and 6" higher than the top of the chuck would suffice. Pretty much just a giant sheetmetal bookend.

I could cut one with our makerspace's plasma cutter and bend it on the metal shop brake.

As a newbie, I find I'm not having new ideas, just stumbling on ideas others have had. Any plans out there?

And that lathe is a "CENTRAL MACHINERY 7 in. x 12 in. Precision Benchtop Mini Lathe"

Always check the fine print, HF doesn't have coupons like they used to...

Why do I know this? I was going to pick up another magnetic pickup tool which is all of $13.99 and it is Central Machinery so no coupon for me...

Thanks Jaques! Using the translate option in my mail client makes it far easier to understand your posts!

The only issue with using magnets to pick up the swarf is that aluminum and brass (as well as stainless steel aren¡¯t magnetic :-)

Using the plastic bag is a great idea; in fact I have a magnet stuck in a Ziplock on my bench for just that reason! It¡¯s also really useful for cleaning up on the bench in general after cutting, filing or drilling stock, too.

I have sometimes considered making some sort of enclosure for the magnets like this:?

Only 5-6¡± long to use as a ¡®bench sweeper¡¯.?

I got one of these a bunch of years ago when they re-roofed my house, even after they claimed to have cleaned it ?all up, I probably picked up a couple pounds of roofing nails and other detritus around the house.?

Re: Grizzly is doing better - I hope!!!

 

HF does very occasionally have an actual no exclusions coupon. They had a 20% off coupon right before Christmas, that was actually 20% off anything. Seems like they do this a couple times a year, with the rest of the coupons either being limited to lower priced items, or excluding so many brands that they are only good for buying fuzzy dice and air fresheners.


On the no small affordable US made machines comment, you are overlooking Taig and Sherline, which are both based in the USA and still being made in the USA. Small, but good quality and still affordable, in fact more so now, since tariffs haven't pushed their prices up.

I am also happy to see Grizzly doing well. Without them and HF it would be a lot harder to find home shop sized industrial tools. Like the auto industry, in the 1980s the US iheavy manufacturing base chose to abandon the smaller size machine segment and focus on large industrial customers? instead of competing with the (then, mostly Japanese, Taiwanese and Korean) imports.

The video shows turning between centers, which nowadays is hardly ever used today, even though it's the only way to repeatedly remove and replace the work in a lathe without losing precision alignment.

But I'm wondering, if this is video #11 in a series, where are 1-10?? Not everybody would have the patience to watch them?all, but he should at least tell us how we can.

He cheats, a bit, because he already possesses the knowledge of turning so it¡¯s not entirely starting from scratch, but then the Antikythera mechanism itself didn¡¯t spring fully formed de novo from some ancient supergenius¡¯s mind. There had to have been a long tradition of metalworking of complex devices to get to that point.?
