What did you use? I was going to use a carbide bit...

I tried to use a cut off wheel on the original plastic baffle. I had setup a little area at the back of my apartment to minimize the dust in case it starts spewing everywhere; but the dremel simply did not have enough power nor precision to do work on the baffle. I'm going to guess its not going to go well with wood either. 

Yeah sorry guys, I should of stated that you guys were going to need a lathe. I hope you guys didn't waste too much money.

I'm sooo strapped for time at the moment or else i'd make them for you guys. 

if you guys who failed could post some pics for others who might think that its possible.

i plan to build 4 of these by the end of next month :)

if anyone needs some work done on a lathe i could help about 3 people i wont provide wood or finish and assuming they would post pics of the final headphone.

Darn all the woodworking stuff I read concerning Dremels was a waste.

You can round wood off quickly and get a decent shape. then Id suggest a forester git to rough out the inside of the cup then use that same sanding disk to clean up. it doesn't need to look pretty to sound good so don't let that put you off.

I just ruined up a nice piece of wood by not thinking what I was doing so even after all this time I still make major screw ups so don't feel bad if it doesn't go how you'd like... It happens to us all.

I wonder why I didn't think of using a drill in the first place... Yeah I was going to use a forstner bit for the inside.

Oh my word, smeggy is human?!
 

Could someone in the US buy some stuff from McMaster-Carr for me? I want to buy some visco-elastic foam from them with the intention of using it as a gasket. However,  McMaster-Carr would not ship to Canadian residences due to export restriction. :( I would pay for all the shipping and material costs and you could take some for your own project if you need them. :)

I might be able to later this week. I was going to buy from them anyways. It'd have to wait until the end of the week though.

Cool! I'll pm you about it later. :)

If you don't have a high speed/high powered sander, it will just burn the wood causing it to turn grey or sometimes dark purple (almost Black). I've tried to work with it using a mouse sander and it just completely ruined it. 

 

Cocobolo isn't too bad to work with on a lathe but once again, its a very dense/hard wood. 

 

To be completely honest, this project might not be the best idea for people who aren't using lathes. I hate being the bearer of bummerness but shaping that cup without a lathe isn't going to be an easy task at all. 

Purpleheart and Cocobolo are both rosewoods so their properties are very similar.  Purpleheart is a little more "toxic" to people who are sensitive to Cocobolo.  I can confirm that Purpleheart splinters hurt far more than any other exotic wood I have every sent into my skin.  It will continue to itch or burn until it is removed completely.  If you aren't sure how it will bother you, wear a mask and gloves.  I just put a small cut in a block, then sniffed the cut and picked up the sawdust with my hands to see what it did.  I knew it wouldn't be fatal, but I was curious. Makes me sneeze like a mad man and it's constant until I flush my nose with saline solution, but it doesn't bother my eyes or hands, so I can get away with just a dust mask and Benedryl. 

Be careful with burls too.  Burls are formed in the wood by a fungus, so you can very serious allergic reactions to burl dust. 

There are sustainably harvest or farmed South American woods too, so just do do diligence ahead of time.  Be concerned about wood blocks that are waxed.  Again, a lesson learned the hard way.  I lost at least 3 sets of SFI pucks in Cocobolo from a bad bock of wood that was waxed so I couldn't see the stress crack in the wood.  It popped on the 3 sets of pucks about a day after they were all cut out.  The one good set became a very expensive pair of wood cups.

Does this mean we should avoid buying waxed pieces, or is there some way to differentiate stressed pieces from good ones?
