post your grado mods.... - Page 181

I've been quiet for a while now..

Ditched the full-on design in Solidworks and wanted to give the lasercutter a chance.

Got a similar to original design ligned up, ready to be cut. All I need now is a slate of 8mm plexiglass, to complete the required materials.

Expect pictures very soon :)

What kind of SQ do you get from glue?

Nope...they were made from a solid piece of bamboo.

Really nice looking cups. If you don't mind giving a few more detail about your build process that would be great. Did you use a lathe or a hole saw? How thick was the innitial chunk of bamboo? I'm looking to make something like this myself and would love some tips. Thanks.

My own unique maple cup design for my MS-1s. Sitting on my own unique hickory veneered book shelves with HiVi B3S drivers.

Ah! A step closer to the holy grail...not quite there yet, but almost a closed back Grado....

Finally had some playtime with the laser cutter!

Design is finished, but ran short in time to cut all the rings.

I'm missing a grill and the smaller diameter ring after the cushion right now.

Also i need to design the rings to hold the driver down, but I can't measure that untill after I liberate the drivers.

Designed to be cut from a single sheet of plexiglass.

In my case i had some spare red and blue to indicate left and right.

Hoping to start assembly soon.

A few Gradoheads from the local DIY headphile community created them.

The cups are factory made using a CNC machine.

thought i'd poke my head in this thread to note what I feel is an increasingly key grado mod point. That being how the driver is mounted to the cup. Case in point: I recently tried to transplant my absolute favorite drivers from it's current cup which has a perfect press fit for the driver to a near identical cup (same mass, same finish, same wood, same cable) the only difference being that the opening was wider and required a wrap of tape to get the driver to stay put. result. total loss of mojo. Popped them back in their rightful houses and whamo, mojo revisted. lesson for all us grado modders to consider how that driver mates up with the other half of it's functional 'resonance' partner.

actually that wasn't the only difference in the two cups, one had a little more mass of wood around the lip of where the driver mounts. Otherwise the cups were real close in shape and mass. will take a pic later in case this is of interest to any 'yall

added pic:

the finish is the same, pic shows end grain on top so it looks diff/darker

Please share :)...my 225i drivers and cable are wrapped in a foam tape to keep them in their woodies, and I found their sound was warmed up, the bass went deeper, and they became a lot less fatiguing to listen to...
