Yep. Our grinders must stop if we let go. Triggers or paddle switches. I've worked several jobs that were like that.

I'd find another job. Aint no way I'm grinding all day with a P.O.S. paddle. ESPECIALLY if the nanny lock has been left intact.
The trigger on a rat tail is fine. My 5020 is a favorite piece.Major control.
Most of the time i use a Bosch Slim, one handed.Runnin a paddle one handed is goofy......unless she's bent over beside the Jacuzzi :mrgreen: :ugeek: :lol:

When I responded on Boob T00B I said I'd post the moddifuckated grinding cutting bib from Carharrt and, this idiot posting it. :lol:
Isn't hard to see what I did once you purchase the bibs.Baddest hot weather apron on the planet. :D
The belts position ansd stitching keeps the stiff canvas protecting the sides of the legs.I re-did that a couple times to get it to work.

Awesome job on the apron . I have that same bib, use it for snow riding on the dirt bike, its a tough bib...never thought to re-purpose it like that. I have had to repair a few rips over the years on it, I've had good luck sewing it up with Kevlar fishing line as thread, then applying Loctite GO2 glue over the repair... holds up really well.
Great video's on the angle grinders, watched all 3 of them, thanks for posting !

Another vote in support of your videos.

For some reason, my local technical college decided that all industrial classes would require full time enrolment. That makes it kind of hard for someone like me who wants to attend a class or two to improve a skill or learn something new.

These videos are invaluable learning tools.

UV,

Awesome information there ! I thank you. You are certainly correct on the DeWalts. I have one at my workplace and it's about 12 years old. The other day our young whipper snapper of Deckhand found me and said it's shorted out and won't work.
I took it apart and found the factory original connector terminals from the main cord had just worn down over the years (these things have TONS of hours grinding rust for paint repair and metal prep) so I removed the originals and crimped on some new ring connectors...she fired right up !

Another personal tip: I will regularly take our pinpoint air nozzle (with a reasonable psi) and blow the vents and exhaust ports out. This keeps accumulated rust and metal dust from gumming things up and they seem to breath easier;like an air filter on an engine.

Thanks for your videos - Shawn

Nice work on your vids, UV. You hit the nail on the head when you nailed your head with that grinder. I was once wearing a loose t-shirt while using a wire wheel which of course, caught the flapping-in-the-wind shirt and tore to shreds not only my shirt, but my belly as well. All is good now and I learned that suffering for your art doesn't need to be painful. Some lessons I learned? For wire wheels, I use only the knotted cup style, when I do use one, as it's a little bit safer and throws fewer projectiles, loose clothing, NYET! Porcupine legs and forearms are the norm with wire wheels, so I avoid them. Don't forget the face shield when using ANY wire wheel,but at a minimum safety glasses; better yet, eliminate them from your repertoire, you will find other ways to do the same thing with things like flap wheels, etc.
Although you only touched on it in this series, I think that you understand the value of a neat workplace. I will stop work just to sweep and put away tools every once in a while, wipe off the welding table, collecting cords and other trip hazards. Makes the day that much better when you're not always working in filth and your work lays flat on the table...imagine that, improved fit-up. As you know from your many years experience in a metal shop, safety is on-going and proactive. Tripping in the messy metal shop could easily cost you teeth, an eye or even another hole like the collection in my head!!
Keep up the good work, you put a lot of consideration into the subject and supply good information that not only applies to newbies, but those more experienced like me, who forget about best practices when the clock pressure grows. A reminder or tune-up on safety is always timely, cheers! :D

Good videos, thanks for posting. I also had a grinder with a wire wheel eat my tee shirt...it stopped just below my chin. :o

Great videos! I was hoping to see something in there with Metabo tools, but there wasnt. Oh well, still a very good series.

Thank you UV! I thought the only thing to learn about grinding was some basics about what disc to use and learning how not to grind yourself. WOW! Seriously awesome information and you might have just influenced me to purchase another grinder :)

I posted this as a comment on the Harbor Freight site for their paddle switch angle grinder. It was meant to be whimsical, but I do like their grinder. I wanted to solve the cord problem.
I now own 9 of them, so I NEVER change what's on the spindle unless it's used up. I have spares as I'm on an island and it takes at least 2 weeks to get things shipped in. Those spares are actually used and sport duplicate spindle tools (cutting disk, cup brush, etc) so I can swap grinders when one starts to get hot from (mis)use. My tree is too small to hold all of them now, so I'm going to make a new one and hang it besides the original grinderensis roatansis :D
===============
New species of Harbor Freight tree discovered!

The tree, appropriately named grinderensis roatansis, is found only on the island of Roatan in the Caribbean.
It's discoverer knows it to be the only one of its kind.
This evolutionary development allows many angle grinders to occupy a small vertical space, and especially solves the power cord issue.
Earlier attempts at solving these problems invariably resulted in tools all over the place and cords being wrapped around the body of the tool resulting in an unruly power cord.
This new species of tree may spread to other areas of the world where fertile minds and a bit of welding can create clones.

Saw you videos on YouTube. I am new to grinders, and you had good, solid, and complete info.

Good subject.
I agree with you Mike.
I have nine electric angle grinders and a drawer full of air powered. I still have the first one that I bought used in 1958.
It's 9 inch Black and Decker that bears the name "BAD ASS".
They are the most dangerous tools in my shop and I have bled a little from time to time when I didn't treat them
with the required respect. All my grinders have lock-on switches including the several that have worn out and been
replaced. I wouldn't have it any other way.
I will also mention that the wheel guards are back on most all my grinders.
Safety is one obvious reason and having a large quantity of extra right-hand gloves is another.
I've had success modifying some of the guards, some don't need to be that big.

Thanks everybody. The 3 part angle grinder series is by far is the most popular work that I have on youtube. At the time of publishing it, I really saw that there was a need for this information to be shared, so I made the best effort to make it as good as posable with the knowledge and resources that I had available. I would like to invite you all to visit my youtube page again because there's a bunch of new content all related to metal working there that I hope you find educational. Cheers UV
