My Version on a 24V billet lookin Valve Cover

[JB @ C and L Machine]

Here I am milling the top flat

then milling the sides

Valve cover

"WOW" That is outstanding! great job,Those who have a vertical mill are blessed! GWD

 

[HoleshotHolset]

SWEET!!



I really like how that looks...



I'm jealous... . I wish I had access to and the talent to run machining equipment like that.



Matt

 

[Proram]

Awesome!

John, when i get Better, i realy wanna come and see it in person,

absolutly Beautiful!. (wanna do mine? just mill no polish)



Later, Scott

 

[csevers]

Is that a one time deal to make your truck "original" or are you going to do this as a service? How many hrs of polishing?? It does look real nice.

[Bob Wagner]

jb, was your cover magnesium? thanks bob

 

[JB @ C and L Machine]

Craig. . I would mill anyones VC... . but the polishing is a serious pain in the butt.



Bob. . mine was Alum... . on a side note. . on the magnesium, If your machine it the wrong way... it can catch fire!!! My father saw a machine burn to the ground

 

[Bob Wagner]

thanks jb, will mag shine like aluminum? I am not looking at doing it.



Shoot John Treibel a PM

 

[csevers]

Please explain the fire and magnesium thing I am curious as to how what were when if you could.



Thanks

Craig

It's real simple, it makes it's own oxygen! Old airplanes had allot of mag in them, the procedure for a magnesium fire on board a ship is to jettison overboard(airplane)

In a nut shell Craig and in my own words , this is what I know about Mg



Magnesium, symbol Mg, silvery white metallic element that is relatively unreactive. In group 2 (or IIa) of the periodic table (see Periodic Law), magnesium is one of the alkaline earth metals. The atomic number of magnesium is 12.



The metal, first isolated by the British chemist Sir Humphry Davy in 1808, is obtained today chiefly by electrolysis of fused magnesium chloride. Magnesium is malleable and ductile when heated. With the exception of beryllium, it is the lightest metal that remains stable under ordinary conditions. The metal is not attacked by oxygen, water, or alkalies at room temperature; it reacts with acids. When heated to about 800° C (about 1472° F), it reacts with oxygen and emits a brilliant white light. Magnesium melts at about 649° C (1200° F), boils at about 1107° C (about 2025° F), and has a specific gravity of 1. 74; the atomic weight of magnesium is 24. 305.



Magnesium ranks sixth in natural abundance among elements in crustal rocks. It occurs in nature only in chemical combination with other elements, particularly as the minerals carnallite, dolomite, and magnesite; in many rock-forming silicates; and as salts, such as magnesium chloride, in ocean and saline-lake waters. It is an essential constituent of animal and plant tissue.



Alloyed forms of magnesium have considerable tensile strength. The metal is used when lightness is an essential factor: alloyed with aluminum or copper, it is used extensively in making castings for airplane parts; in artificial limbs, CUMMINS VALVE COVERS, vacuum cleaners, and optical instruments; and in such products as skis, wheelbarrows, lawn mowers, and outdoor furniture. The unalloyed metal is used in photographic flash powders, incendiary bombs, and signal flares; as a deoxidizer in the casting of metals; and as a getter, a substance that achieves final evacuation in vacuum tubes.



The estimated world production of magnesium in 1989 was 350,000 metric tons. The estimated United States production in the same year was 148,000 metric tons





(Other than that, I dont know much about it either. )

BTW, I really like the valve cover. Thats trick!

 

[Chipstien]

Once Magnesium catches there is pretty much no stopping it. Heard of magnesium catching fire and burning clear through 1" plate steel. Now that is a hot fire.

 

[JB @ C and L Machine]

Am gonna have to do some more re-search from my school books from what I remember, that when machining mag that the speeds,feeds, and sharpenness of tool is very important. I was hoping John from the nw site would chime in. I'll pm him. JB

 

[FFL8N]

What ever you do... . don't put water on it to try to put it out!! :--)



Magnesium burns so hot, it actually breaks down the chemical bond in water and turns it into Hydrogen and Oxygen... Now you have an all new fire!!!!! It does look cool though! Stand back and let the sparks fly!!!

 

[Sticks]

Mg has a low flash point, and an extremely high buring temp (5400*F). You can't smother it (cover it in dirt or some such) it will continue to burn quite nicely. It has to be chemically snuffed.

Watch it burn

If you want to see magnesium burn, find a old aircooled Volkwagen engine block. These are made out of magnesium. Bust it up and toss a SMALL piece into a nice hot campfire. Once it starts to burn, get out the sunglasses. It makes an unbelievable amount of light and a nice plume of white smoke(which is probably fairly toxic so don't breath it!)

I'll bet there was beer involved in that little science experiment

 

[CFAR]

The VW transaxles are Mag also, Had a friend cut one with a torch, it eventually burnt out.
