from what i gather HF2 has a wooden driver holder and aluminum outer shell just like the PS1000 but hte PS1000 has more mass so it provides better/different............????

Both headphones have mahogany undies and aluminum coats.  The PS1000 has a larger aluminum coat.  It also uses jumbos instead of bowls.  Less visible is the fact that the PS1000 vents four holes while the HF2, at most, vents 1.
 
I owned the PS1000 and the HF2 at the same time.  Unamped, the PS1000 had more thump than the HF2 and more HF extension.  When I swapped out the bowls for jumbos, the HF2 had what sounded like the same HF extension but the bass wasn't quite prominent enough to remain full without the aid of a strong headphone amp.  I remain convinced that the HF2 would have the same bass if you vented the driver further.

Haha can't say I would have ever thought to use frickin' laser beams to DIY a headband for my headphones.  I feel like that should go in the "you know you're an audiophile when" thread.  Totally awesome.

PS: The headband looks awesome.  I'm also debating about a DIY leather headband project.. but more along the lines of the cardboard/glue/razer blade variety.

UPDATE
 
I think I've fixed the "where's the grill" issue that popped up.  I spent the evening grilling up every shell I've already drilled and dremeled to fit the C clamps.  Due to the number of shells involved, I didn't use the largest mesh I've got, which is stiffer and more expensive but I'm happy with where things ended up on the other shells.  Some things seem to work better in the quiet of night rather than in the rush of the afternoon, though now I'll need to hustle off to bed before I turn into a total zombie.

Look at all those.

Wish I could buy a bunch of Grado SR60s and change each one out with these cups. One Grado SR60 for each type of wood. That would be awesome.

Yep!  That's the headband thread I was planning on following.  Looks like a good place to start.  I was thinking maybe finding some kind of memory foam sample or something to use for the padding.  Might be too much hassle tho.
 
Bilavideo you're a machine!  Those look great

hey man!

i dont know anybody in this country that has an SR325 let alone a Grado can... im still enjoying my SR80i woodies and well i just cant resist the temptation of exploring deeper and getting into the aluminum world.
 
ive not seen spec sheets of grado GS1k and the HFs ones... if only someone can provide me...

I was able to locate a pair of SR325 vintage, non "i" model locally on Craigslist for $110.  The purchase was a "no-brainer" for me.  They do exist, but it takes patience for them to come around every now and then.  On the other hand, why not just purchase a pair of SR60i headphones and try the aluminum liners?  After all, the aluminum will more than likely do a lot of reflecting of the sound  and even though the aluminum is in the plastic housings, the only thing you'd be giving up is asthetics.  Plus, if it sounded bad, you could just buy a proper pair of wooden cups to finish out the SR60i mods ... and have some great headphones.

Wje, did you find the vintage black aluminum 325's? If so, you are lucky, I have been looking for a pair of those.
 
Bill, that looks awesome. Makes me feel better about the 10 cups I have sitting in my room with 1 pair of headphones. Would it be possible to get some pictures of the different woods you are playing with now? I see some Zebrawood there for sure, which is the last wood that I want to experiment with I think.
 
Those lacquer fumes getting to you yet Bill? The weather is finally getting nice enough for me to spray outside (as opposed to in a nice closed basement). No matter how well vented, the fumes still get to you sometimes.

I don't know if anyone has checked out InnerFidelity, its the new Stereophile website for headphone stuff. Its actually pretty good, run by Tyll Hertsens, former CEO of Headroom. Well one of the first articles is a comparison between all the Grado pads, current and old including some modded ones, including measurings and the whole shebang. Pretty interesting stuff. Also cool is that the last page has a link to resources and he calls attention to this thread. I would at the very least check it out, its some interesting reading, even if you don't agree with his findings.

Thanks for the props, Sharkz.

Bilavido, if you want to get some measurements of your stuff in the database, I'd be happy to do so.

the photo does not do the band justice. when are they going to make the isight in hd??
 
i first designed the grado logo on adobe illustrator. then i laser cut them, the shape of the band was vector cut (all the way through the material) and the logo was raster (engraved). i'm very fortunate that my school has a lineup of laser machines and other hi-tec doohickeys.

There is a good DIY tip there... A friend and I take machine shop classes at a local community college. Classes are dirt cheap. The highlight here is we get access to all the shop equipment. Lathes, mills, even CNC! We've taken the same class over and over, so the teacher knows we are there for shop time. As long as we don't interfere with the class he's happy for us to work our projects. Bonus, he's happy to continue to teach us as we progress into more complex projects. I think these classes are pretty common in most areas, worth keeping an eye out for if you've got an idea, but don't want to invest in a large home shop.

I took a knife and a hammer to my SR60's today. Oh and a vice was involved too

Anyway Bill's video succesfully guided me through the process of partially liberating a Grado driver from it's plastic housing.
 
Operation Blackwood has commenced
