cleaning metal

[Rustydog2010]

Just a light film of oil will keep it, at home we pretty much live on the sea, and its bloody windy. In excess of 100km/h
To keep the bed of the mill, lathe and drill press from forming rust, I just clean them down and use Engine oil and just brush it on. Works like a charm

We use engine oil on ours too, and 6% soluble in the coolant.

you can get wire wheels for the grinder. they work 10x better than the drill kind. takes rust and paint off instantly. Thats what i use

I've had one of those expand on me, holy crap that was a buzz, you should always check the max rpm on all attachments

because one day murphy will arrive, typically when you have no grinding guard on to fit that slightly larger disc you scrounged of the 7inch which was taken off 9 inch which beforehand was on the drop saw and who knows, somethng bad will happen knowing murphy......

ive had near eye misses with wire brush coming out of the 35,000 rm dremel. i learned something... ALWAYS WEAR SAFTEY GLASSES WHEN USING WIRE BRUSH! i almost learned the hard way.

 

[fowler]

ALWAYS use saftey glasses when useing any tools even hand tools

 

[Rustydog2010]

I agree, i probably look like a d#$% but will always use safety glasses and earmuffs. No injures yet

 

[fowler]

i use the standards at my work as my standards at home so wearing a face sheild while grinding with saftey glasses and ear muffes but iv had bits of disc hit the sheild and i am glad i looked like a tool cause i still have a face

I think that happens a few to many times..

A serious question, when a cut off disk for a 9inch grinder gets small enough to fit on a 6-7inch (Safely!!) Is okay to use? Not that i have done it, it could save you a lot off money on disks.

 

[fowler]

i dont think so as if its diamiter is smaller than its proberly thinner as well

 

[Bluethunder3320]

hmm, they also may be weakened as well

 

[fowler]

thats what i was getting at

 

[Doc Sprocket]

Arbor size may be different. If it is, don't even think of it.

Buy high quality cut off disks also... Cheep ones will shatter, take much longer to do the same work, And can be horribly un-ballanced. Ive learned even grinding disks its better to buy the good stuff... Take a micrometer or what ever else and measure a bunch of cheep disks thickness.. Its suposed to be around 2/32nds i think it is.. It can be off by alot!

 

[Bluethunder3320]

yeah i just figured that out bought a 15 dollar grinder and a 1.50 disk... works awesome for the money cant go wrong but it is unbalanced....... like the second i turned it on it was shaking like hell

 

[r97]

thats why i call it "wrestling with the angle grinder", decent gyroscopic forces going on there (?? yea i really have no clue what i'm talking about, but it sounds cool, lol)

p.s. my 1 cut-off wheel is about 2" in dia, its supposed to be 4.5, getting tough to use, lol

 

[Bluethunder3320]

buy some more, haha! yeah its so odd like i turned it on and orbited it in the air and its doing freaky aeliean moves like its so cool though
