Titanium grinder?

So theoretically, let's say you had a close friend who had a water jet cutting setup and you could choose to have the 1/2" plate you are planning to construct your next grinder out of be either titanium, or steel. Which would you choose, and why? Just theoretically speaking of course.
 
Steel because it's cheap.

If the titanium is steel price, then titanium so I could sneer at all the poor people who can't afford titanium grinders :chuncky: <--- I'm kidding. It would be cool but I don't see a practical reason to use it versus steel. Having the grinder be heavy isn't a bad thing.
 
If you were doing a lot of nasty wet grinding the ti grinder would be rust-proof and of course mega badass, but I'd still prefer to use a heavy, solid steel one.
 
Steel! there's more to making a grinder than just cutting out parts. Those holes both threaded and not I believe could become very challenging. My grinders don't look rusted out in the least.

Steel. Easier to fabricate. At least I am not set up to weld titanium...
Also, despite my otherwise perfection machine building, something is going to get wonked.
Heavier steel density fights vibration.
 
I was assuming tapping holes would be the big issue. They fabricate with titanium at his shop, so he could build the entire thing for me. But since he is offering to do the waterjet and supply the material, I'm not pushing my luck. My kingdom for an easy way to tap ti!!
 
Ti would offer no practical benefits that I can see, over the "cool" factor. I'm nut sure it'd even have any benefit over aluminum.

Also, while waterjet cutting titanium isn't a problem, when it came to tapping holes, or performing other machining operations, you might have some trouble.

As far as mass is concerned, I imagine a grinder built out of 1/2" Ti plate would be plenty stout, but I just can't help but think it's a bit of a waste of material for no perceived benefit.
 
I was thinking about building one out of adamantium but I can't find a supplier for kryptonite drill bits, and Spider-Man quit selling his special Spidey welding wire. I did find a rebuilt engine from Wonder Women's invisible jet to run it but I can't seem to find a used Iron Man arc reactor to power it so I guess I'll just use steel.

McMaster has kryptonite drill bits. They have everything.
 
Most of the kryptonite these days is just just cheap Chinese mithrel. You got to get the old ones if you want real kryptonite.
