Wasn't aware Naval Jelly was that hazardous!! I've used it a couple times to remove rust on some pieces and experienced no adverse tramas, but was I lucky or flirting with disaster?? Instructions simply said wash with water after it did its work. But that was in the 70s when things were done "differently" i.e. drain yer radiator at the curb and run the hose a while so it didn't kill yer cat.

Steve,
Another oversimplified explanation, (kiss;)) might be that they are advertising the high and low end of typical useage. 40 psi being the minimum that most paint sprayers woul require and 90 psi being the highest working pressure that OSHA will allow in the workplace. Just a guess, uneducated at that :)

Nolano, Ed T, Hofi,
You guys beat me to the punch but are absolutely correct about using grinding wheels on soft materials such as wood and aluminum. Its not a matter that they can clog. They WILL clog and become a time bomb. Saftey shields should be used regardless of the conditions but an exploding wheel may not discriminate. An alternative might be a hand held 4" or 9" grinder. They will still clog but they are reinforced with fibers that reduce the risk of explosion. Plus, the grinder's guard will stop a good deal of debris if it was to come apart. That doesn't help the innocent by-stander, however. Always be aware of spectators!! Flap wheels are most likely the safest and most effective when using this type of grinder and they move an incredible amount of material while leaving a nice, smooth finish.

Ellen,
Thanks for clarifiying the scfm / cfm difference. If I understand it correctly then scfm would denote perfect texbook conditions and cfm would denote actual average shop conditions? I know thats probably grossly over simplified;)

WICKED!! I like it. Very Tolkienish ;)

Tracy,
Welcome to the forum. I was stationed near Irvine at MCAS El Toro. Not much of it left these days;)

Sign on shop door: "Work done good, fast, cheap. Pick two!"

JWB, LOL! My cover has been compromised. Improvise, adapt, and overcome!! Yup, Fully aware of moisture and dirt problems and am planning accordingly. Thanks :)

Welcome from Omaha Gary;)

Let me rephrase the question. What would be the smallest compressor I could get away with? Would a smaller one, say a 30 gallon tank, just limit the cutting time or would it limit the cutting capacity etc??

I am getting ready to buy a plasma cutter. I've never owned one myself but used one at work for years and took air supply requirements for granted. Now that I am going to have to be aware of it I realize I may need to get a bigger compressor. You guys and/ or gals that have a plasma machine; How big is you compressor??
The plasma machine I am looking at requires 270 scfh ;4.5 cfm @ 60 psi. I saw a compressor at HF that claims a rate of 6.0 scfm @ 40 psi - 4.2 scfm @ 115 psi. By doing the math, this seems to cover the range but it only has an 8 gallon tank. Do I need a bigger tank? Whats the difference between cfm and scfm? Same thing??
Pre-thanks for your input :)

Brian,
The Marine Corps moto is "Semper Fidelis." In latin this means "Always Faithful." Us jarheads say "Semper Fi" as a common greeting to other jarheads but as I've said before it fits any close knit group to mean "I got your back!" Thats what I mean in my signature that "its not just for breakfast anymore I never saw any combat or overseas duty for that matter while I was in but we were always prepared for that "call to duty". Your son has answered that call and to him I offer him a hearty SEMPER FI!!

Sorry, I haven't checked this thread since I first posted complaining that it didn't work. I need to be more patient Neat process, albeit time consuming. I started one of those rings from a silver dollar many years ago. Drove my mom nutz with all the tap, tap, tapping. But, that may have been part of the motive. he he (I was only 14 or 15) I got frustrated with the tedium of the spoon "hammer" and soon switched to a small (8oz or less) ballpeen to speed up the process. This, however, caused the ring to start an "s" curve around the circumfrence. Interesting but not desired effect. I think I may still have it buried in my "treasures" somewhere. I'll have to try to dig it out someday and finish it. Might even fit now as my fingers have gained some girth since then LOL

Hey Joe,
Welcome. Looks like the bladesmiths are taking over! LOL It wasn't my first interest when I started, but I am gradually being converted. :)

Awsome work Jerry. I am going to be changing idler arm and pitman arm on my Dakota soon. Plan to "recycle" parts;) Dunno if I'll get to it for this thread but will post when done!

Welcome Mike:)

Nice blade Victor. I'm just learning about harmon lines and such but it looks good from here. Have done a bit of photography and Jens (Oakwoodforge) is right on with his shooting tips.

If you opt to lift anything heavy with a cherry picker, engine hoist, block and tackle etc, keep in mind the center of balance. Most of the weight of a power hammer is in the anvil but weight can fool and tragedy can strike quickly! Manny odd shaped things like power hammers, lathes, etc may have the bulk of the weight to one side. Many factors need to be considered when lifting heavy objects. Have plenty of help. Even if you can manage a cherry picker or engine hoist alone, the balance can shift if you aren't using the proper lifting straps or slings. Chain is most susceptible to shifting when weight is applied. Remember, the toes, hands, LIFE you save may be you own!!

Welcome Andy,
I'm a newby when it comes to blade work but having fun learning. I hope I can enventually produce something that nice.

Welcome Cooncreek:)

You were given good directions:) Welcome!

Howdy claypipe,
There are a few farriers here but we don't hold that against them LOL. Most of us are hobbyists. Some even serious about it Seriously, this is a fantastic source of knowlege. Welcome!

AutoCAD is another one, but there again, without some training and a fairly greasy wallet, its out of reach to most. I hear there are a few resonably priced ones out there, but can't attest to their ease of operation. That seems to go with that third dimension. Good, Cheap, and easy? Pick two! ;)

Chris, Those remind me of that ribbon candy that ya find around Christmas time! I bet the bok ends don't taste as good tho LOL
