OK I will burn these I'm for another days giving them 100+ hours of burnin.
I am struggling to find a local source for thin hardwood to make my cup extender. Shipping is going to cost me 5 times the cost of the wood if I buy online!
Here is my plan for anyone interested. I am going to buy Shure 840 pads (89mm by 109mm oval). Buy 1/16" thick cherry wood. Cut three ovals. Two will be 89x109 and one will 83x103. The bottom and top pieces will have an inner oval cut the exact size of the plastic plate holding the driver. The middle piece will be the smaller oval with a hole cut to the size of outer edge of the driver. The 3 pieces will be glued together and will fit over the plastic plate. The smaller diameter oval in the middle will allow room to tuck and hide the 840 pad lip. The middle plate will have 3 matching screw holes to allow the plate to be screwed into place using the existing screw anchors allowing the plate to be removed to return the headphone back to stock configuration. By making the top and bottom plates have an inner oval the size of the plate it would allow people the option to incorporate the original foam underneath the 840 pad whixh the ear would rest on enhancing the isolation. I am going to either paint the extender black or possibly stain it black to retain some of the wood grain.
What I might need is a willing partner from the US to buy and cut a sheet of wood up into 3.75" rectangles and mail them to me. I am going to check out the local lumber store locally on Monday first though, just in case I can find someone who has what I need in stock.
Here is the one online reseller I have found in the US, that had 1/16 cherry wood sheets available. http://www.kencraftstore.com/woods/Thin_Lumber.htmlEdited by dweaver - 3/29/14 at 5:22pm
