A bunch of things when you are using a grinder.
WHERES YOUR **** EARMUFFS!!!
Sorry about the shouting but in a few years everybody else will have to shout to you too....
Oh, and your safety glasses, I have had about 10 visits to hospital to get flecks removed from my eyes thru grinding, most just fell in there but a few flew in.
So this info is all from experience.
If you feel something in your eye, but can't see it, still see the Doc, its a burn & the scab is what you feel.
They will give you eyedrops that'll make it heal in a couple of days. (eyes are the fastest healing part of your body)
If it heals wrong it will cause a scab, that can ulcerate after 3-4 days & cause a hole in your eyeball & the fluid will leak out & you will go blind in that eye.
Theres no way back with your eyes.
They use a special pick & pick the scab off & it'll heal in a day.
'Fukitohelmik' or something is the name of the eyedrops I got (I'm not joking!)
Actually I just checked it. Its 'Fucithalmic' http://www.medsafe.govt.nz/consumers...ucithalmic.htm

Gloves, actually I prefer what you have done, use one on the left hand only, better grip on the grinder.

You are right about the right side of the steel strip to cut thru, I cut thru the other side thinking I'd save Cu.
I ended up having to hand pick each loop-end out as they burr over & get caught, almost welded to the steel ends.
It took ages.
---------
Put the object you are cutting thru on a solid support, if it moves, you can see how it catches in the vid, it rips chunks out of the grindstone. Causes accidents too.
You can see it on the cutting edge, it should be fine, like sand, rather than chunky & sharp & grainy.
I kneel/stand on the slab to hold it, keep the revs up & work finely/slowly to save on discs, I use a 9inch, thats what I have, I save the worn discs for the 4 1/2 inch.
----------
Let the grinder get up to speed before cutting, that way the disc holds onto its inertia, otherwise the motor has to make up for it & it overloads the grinder & causes you to work more. The stones are made to cut at certain revs, the top revs the grinder does.
Actually its 'Metres Per second' Thats why you can use the worn big discs on a smaller higher reving grinder, the MPS is the same.
In a perfect world I'd have a 9, 7, 5 inch grinders with different discs. Cutting 9 & grinding 7&5.
-------
A BIG deal about working around cars with a grinder. DON"T!
The hot metal grains that fly out are red hot & when they hit a windscreen they melt into the glass a bit.
They then sit there, embedded, then they rust........ Then they rip havoc out of the window wiper blades, instantly, forever.
If you try & chip the grains out, they remove a bit of the glass & leave a chip hole, ruining the finish of the glass.
I guess something similar happens to the car paint too.
--------
I hate craft knifes, thats a personal thing though. I saw a guys hand a few days ago where he cut right thru his thumb, to the bone, 4 stitches, doing scrapmetal.
I used a superthin 4 1/2 inch disc for the same job.
The bandsaws a excellent idea, so usefull.
I love the idea of folding the condensor around a tube, I didn't think of that & ended up using needlenose pliers & standing on the thing & ripping the tubes upwards. That was a real back killer, walking around hunched up groaning for a while afterwards.
I'm constantly amazed at the cleanliness of American workshops.
Our NZ workshops are all dark dirty '****enson' like pits of grime & soot & oil caked dust layered with rust.
(Thats like a Charles ****enson blacksmithing workshop)
Impressed with the video too, quick, sharp, easy to see & to the point. You have saved a lot of people a lot of time.
Thanks again/e
