THANK YOU for talking about keeping the guard on an angle grinder. I get really frustrated with fabrication channels on CZcams that present themselves as how-to guides for hobbyists, then show the alleged expert using an abrasive cutoff wheel on an angle grinder with the guard removed. As you mentioned, when one of those things flies apart, it sends shards out at unbelievable speed.
Good video that also reminds me of the need for strong hearing protection when grinding. Just listening to the video makes my ears ring.
Excellent review of grinding process,thanks for taking the time to make this video
This dude is like the Bob Ross of welding😂😂 I love your show!!! I'm a beginner, got any books or tips you could direct my way??
Bob, Thank you!! You remind me of my high school auto mechanics instructor. He was a great instructor and took the time to explain and show you how to do things. Just learning how to weld at 62 and sincerely appreciate the videos. Again, thank you!
Bob, you are the man.
Excellent vid Bob, thank you.... Cut off wheels are the WORST. Also, snagging a sanding disc, chipping it, and then the vibration....! Cheers....!
One of the most important topics to be covered on welding. I see a lot of unsafe practices being done by CZcams makers and it's kinda scary the amount of influence they have. I would love to see more on safety and metal prep if you guys would be willing.
Face mask or some type of filter for particulate. Welders don't need any more help getting lung cancer, emphysema, etc from the welding fumes and other dust. Grinding dust is straight up bad for you.
Great video Bob!!! Not one I expected to come but you gotta be well rounded and know how to do it all. Thanks!!
R.D. Mercer. I still have some of his stuff recorded. Funny, funny, man. Great Video Mr. Moffett.
I think Bob listens to Ron White with the coupons.
Alvin Wheedleton You got me!
When I was in college I drank with Ron White at a bar in Appleton, wi, I told him a bad joke for a drink. Also i use a "dingle ball" cylinder hone on a flex exsention with my drill for cleaning the inside of tube/pipe. Works great.
Alan Michael Good stuff right there.
I love your videos especially because I'm learning very informative 👍
Super video not to forget hearing protection
Something bob is pretty loose on surprisingly. Any time using a grinder, any loud machine ear plugs ear plugs ear plugs. Hearing will never return.
Great video! Thank you for clearing up grinding with an 1/8 inch disk. I see people doing it online and it's crazy scary.
Same here. I always only hand-tight the grinding-wheels etc.... I maintain the treads also from time to time with tap/die and put never-seize any next month.
Great video on an important topic no one seems to cover. Thank you.
The guard I use for my cut off wheels (1mm thick) is deeper and would take that flap disc no problem. If you check out the grinder manufacturer's spares lists they normal show the type 1 guard (like your grinders all have) and the type 47 guard which is designed to give the higher level of protection that thin cut off wheels need.
Preach safety. Everybody gets a guard.
dreambuilderkmg finally some one with the same frame of mandate as me with just leave the gard on haha great video
Yup. Mine have guards on them also. After one kicked back and sliced a knuckle on my thumb a good 1/8" into the bone, guards went beck on. I just learned to live with them now and havnen't found them to be an issue anymore.
Sometimes we need to go back to basics and be reminded about safety. I'm guilty of all of those sins at one time or another. Like you said Bob, you wish you could get that one second back.
R.D. Mercer is a name I haven't heard in years lmao. I'm only 28 but my grandma used to let me listen to him on the cassette tape lol
I prefer to use a grinder with a potentiometer (adjustable RPM) because I found that I don't really need the max RPM all the time. It does wonders when you use the flap discs. Also, I use the 2.5 mm cutting disc to do prepping. If you don't press on it like an animal then there's no need to worry. Does a heck of a job.
And of course: always use guards, ear plugs and at least safety glasses.
Thank you for this, Bob! Nothing pissed me off more (or quicker) than an unsafe worker.
Grant B They don't last long around me.
be safe and see tomorrow Good video
Good learning watching you
Good Lord now I know how and why to grind (clean). Thank you very much.
Great topic Bob. I created a special channel to save this video in addition to the mig and tig process videos I already have.
Its generic lol good video as usual bob love the info and the laughs
Two questions one on hearing protection and the other on grinding when you finish grinding do you stop it before you set it down and do you wear ear plugs.
Leonard Gilbreath I do wear ear protection quite often.
On earprotection...... If things continues the way the are going, then we (the welder/fabricators) soon won´t be needing them no more.
I´ve been grinding/welding for almost 20 years, an in that time I´ve seen huge improvements in noise reduction on grinders.
The ones I´ve got today are way more silent then the first ones I had.
.........................On the other hand, every thing else has gotten more quiet as well.......(wonder why??)
A 10 on the safety.
Great video
WEAR YOUR PPE when grinding at the very least hands and face/eyes. When it comes to thin sanding pads with plastic or rubber backings always try to use rubber backings. A: they last forever. B: if you catch an edge or corner then dont shatter and leave a SHARP half a plastic backing pad spining around. True story, this happend to my coworker who had been around the trade for a long time, the grinder bucked right under the face shield and the plastic pad hit his lip and cut him open like the damn joker. The next week the company switched over to rubber backing pads that we had been asking for for at least a year.
Sad part of every company. They dont provide the essentials until someone gets hurt. Where my dad works somebody got her arm ripped off her body by a 3hp drill they were using to drill a 20mm hole into sheet metal without a guard or and kind of an easy access to the stop switch. They still didnt sort it out and there is still blood on the machine but the workers have to keep on working on there. Even with it being dirty.
Also be careful of wire brushes in tubing ends, sends grinders flying!!
I think you guys would appreciate Project Binky. Funny as hell.
Bob, could you do a video comparing solid mig wir welding and dual shield flux core. Bend test on plate. Advantage and disadvantages. Between the two. Thank you in advance.
great vid.
We all love y'all bob, great video.... does 55 gallons of whoop ass, require butt protection ???
Rigger Chris It's too late for protection if you get 55 gal poured on ya! Ha
And that's why I wear foam gasket safety glasses inside a full face shield when grinding.
I wear in ear plugs when welding, of any process.
Yeah, I'm a hobbyist. I have one set of eyes. IDGAF how dorky I look. I'm geared up son.
I was wondering what happen when you use a single pass flux core wire in multiple passes. Dose it change the weld spec
William Mercer It sure can.
Butt Whip brand desert topping....no thanks! i prefer 36/40g flap wheels to hard wheels for heavy grinding. why or why not Bob?
jim brown I like them too as long as they don't load up and quit cutting.
New to the trade ,where do I Get a graining shield like yours and how are they rated ,thanks.😎
When I use the grinder correctly on the right side it vibrates like crazy!(you cant feel your fingers) so I grind with the left side and its not such a huge problem since I am alone in the shop.
I once bought some cheap cutting wheels. Had one explode with just safety glasses on. I don’t wish that on anyone. Felt like buckshot to the face Lesson learned face shield and quality wheels
My instructor is big on ear protection, that’s the only thing I saw in the video that could be added In.
Great video bob. What’s the part number on that roll cone you have for cleaning the inside of pipes with? I’d love to stock up on a couple. Thanks
I do not have a part number. That would be generated at your local welding supply store or anywhere you buy.
How the hell do you plasma cut that smoothly?
lolz larkin Turn table /positioner or track torch.
Breath right. Relax, loosing your arms. Free your mind.
I accidentally order a metric crap load of 8018 the deal was to good to pass up and didn’t look into it to much. My question is does and 8018 run similar to 7018?
Yes, it does.
Bob ever bend any metal with 1/4 7024
Robert Ward No, 7024 I use on fillet welds mostly.
aww man you would HATE me XD i stuck a flap disc into my thigh once XD no guards, no handles in my defense in working on small shit though and i can never get the grinder in there with the guard on..... on the plus side i dont grind with cut off discs so ive got that going for me
No excuse, use a different tool.
im also using 150mm grinding wheel on my 125mm grinder
Get a bigger grinder. Seriously, some day you guys are going to regret it.
Can someone tell me what that grinding wheel he used to clean inside of pipe is called? Thanks
Grinding stones. They come in various shapes.
Beware of what's around you. I've seen more stuff set on fire with a grinder than with a welder.
Just one question to the "camera guy". (since we NEVER see him) "Just how big a boy are ya"?
Mark Tracy I've seen him in person. He won the national arm wrestling championship 3 years in a row and can hold the camera outward with only one finger and no boom. Dude is beast!
How can Bob get any better, educates us all about welding AND puts the RD Mercer bug in peoples ear. We need more of this.
It proves welders do have a sense of humor, at least Bob does.
What is the stone for inside of the pipe rocone?
Grinding stones. They come in various shapes.
I’ve never seen a grinding stone that size able to run at that speed. New to me.
Good video and tips! Thank you!
But yes, think a little more about yourself! Please use hearingprotection and a respirator! Protect those valuable and sensitive lungs of yours! Grinding dust is really bad for you!
Other than that, thank you for all of yours really good and informative videos. Have learnt a alot!!
Wait there are different grinder wheels and you can cut out bad welds and fix them? My instructor never told me that, oh wait that's because he doesn't instruct -_-
Deathicael That concerns me.
I don't even know how to set my own welding machine for what project I'm working on, allot concearns me
Where are you going to school? I'll help you all I can, if I can.
I think we've already talked once on FB? Dont want to talk in the open about specifics
Deathicael Pm me.
tell me about that dinky little cap you wear bob, I see it on a lot of US welding video's nothing like that here.
Welding cap?
yes, welders dont use anything like that here, maybe because it's too hot. But I sweat a lot, looks like
it might help keep the sweat off your lense!
Jack Dawg Where are ya?
Jack Dawg it keeps the sparks off your head too
Jack Dawg well, if you don’t mind loosing your hair over time then don’t use one. But when a hot spark lands on your head, hair ain’t growing back on that area.
I cringe every time I see a grinder without a guard, it just isn't worth the risk of a chunk going through part of your body (straight into an artery? - no thanks), and if it goes for one of your eyes while not wearing a shield or goggles...
Butt whip definitely has worse connotations than whoop-ass.
Give me a like
AG Electronics CZcams should show the amount of dislikes
