October 14, 200916 yr and i evidently got the measurements right on the first try. (well to .0001 anyway)Using just a compass and a straight-edge? The man knows his Stax.
October 14, 200916 yr Using just a compass and a straight-edge? The man knows his Stax. I cheated. Justin came up with the idea. I did not think it was going to work, but it did. I used the macro lens and took a picture at as close as i could get and still have all the pins in the picture. Then i suck the thing into featurecam and tell it the measured dimensions of just 2 of the pins. And it calculates the rest... And damm close too. PDF's of that connector are just plain not available. If this did not work, i could have used the new nikon microscope at work which has guaranteed flat optics and a reticule for exact measurements. justin's way was boatloads quicker. African or European swallow hardwoods? I'm open to suggestions. The harder the better. Edited October 14, 200916 yr by kevin gilmore
October 14, 200916 yr nice, that's exactly what I did I have noticed two problems. First, quality control isn't all that great on the Stax plugs, from what I can tell. So, just because it fits your SR-007 "perfectly", doesn't mean it will fit everyone's within 0.001". I checked around 10 or so plugs and found a good amount of variance, in fact I was rather surprised. The other problem (which really isn't a problem) are the people using the WPI socket. It's around 5-6% smaller, and over time bends the plug connectors so that they don't fit all that well in a properly sized connector.
October 14, 200916 yr I can also make them round and threaded just like the real stax thing. But the diameter is going to have to increase a bit. Time to learn how to cut threads on the NC lathe...
October 17, 200916 yr I'm open to suggestions. My hard wood experience is quite limited but West Australian Jarrah is very nice
October 17, 200916 yr Need to find the electrical impedance of hardwoods... Anyone know?? chapter 3 pages 21 and 22 of "the wood handbook" has something about that Forest Products Laboratory - USDA Forest Service
October 18, 200916 yr My hard wood experience is quite limited but West Australian Jarrah is very nice It's pretty cheap in Western Australia too! Beautiful dark red brown colour. I had some side panels made for the CD player from this wood - they look better than the original factory supplied option.
October 18, 200916 yr Shit yeah don't I know it... complete pita to "hand" drill. But perhaps with Dr Gilmore's CNC mill it may be ok
October 19, 200916 yr I love it when a plan comes together no errors yet, and i think i can probably sail thru the rest... http://gilmore.chem.northwestern.edu/t2chassis1.jpg http://gilmore.chem.northwestern.edu/t2chassis2.jpg http://gilmore.chem.northwestern.edu/t2chassis3.jpg http://gilmore.chem.northwestern.edu/t2chassis4.jpg http://gilmore.chem.northwestern.edu/t2chassis5.jpg current BOM such as it is http://gilmore.chem.northwestern.edu/t2parts2.xls I'm doing a custom radius cutter for the outside from a single blade carbide bit, edm'd for the surface i want. (because I CAN! ) hand drill??? what are you guys nuts??? i'm going to cnc the stax jacks...
October 19, 200916 yr Author Hand drilling is fun until you mess up. I spent the last afternoon trying to drill 32mm holes into the top of a Modushop chassis where all the air slots are with a stepped drill. I really need a 35mm+ punch....
October 19, 200916 yr Starting to think about a completely custom machined knob... Anyone with some ideas ?? The deep engraving is going to be sweet.

October 19, 200916 yr how about a stylized reference to the "zeners" used in the T2 for the engraving? Some sort of artistic interpretation of the schematic
October 19, 200916 yr Show me what you got... Be creative... autocad 3d drawings in dxf format please... or solidworks, or cativa.... no lines <.025 inch please.
October 20, 200916 yr Very nice! What's the dimensions on the chassis? I love it when a plan comes together no errors yet, and i think i can probably sail thru the rest... http://gilmore.chem.northwestern.edu/t2chassis1.jpg http://gilmore.chem.northwestern.edu/t2chassis2.jpg http://gilmore.chem.northwestern.edu/t2chassis3.jpg http://gilmore.chem.northwestern.edu/t2chassis4.jpg http://gilmore.chem.northwestern.edu/t2chassis5.jpg current BOM such as it is http://gilmore.chem.northwestern.edu/t2parts2.xls I'm doing a custom radius cutter for the outside from a single blade carbide bit, edm'd for the surface i want.

October 20, 200916 yr Remember that there are 2 chassis, another identical one for the PS. The circuit board that goes on the inside is 12 x 16. I think the resulting chassis had better be 15.4 wide x 16.7 deep x 2.96 high (plus feet) (plus tubes) (plus about an extra .35 for the neutrik jacks) Still less cubic inches than a dual maestro chassis...
October 20, 200916 yr The circuit board that goes on the inside is 12 x 16. My house mate is laughing uncontrollably after I showed him this with a tape measure... his exact words were "isn't that a bit much" I could make a small surf board with that much fiber glass LOL.
