Built a Flexi-type rack?
John,Nice score on the brass. I figured that since the final weight of the rack was in excess of 200 lbs while fully loaded, there was no need to firmly tighten all of the weight-bearing brass cones - the sheer weight of the rack alone would provi... 
Where does your user name come from?
you said it. 
Built a Flexi-type rack?
The aluminum (or whatever material) jig doesn't have to be square - simply consistent - though being square certainly helps align to the corners of your workpiece. Mark the jig as to what the top outside corner should always "key" to -- in other w... 
Built a Flexi-type rack?
Measure twice and cut once! When I drilled my shelves (on a drill press which I know to be mandatory - it is nearly impossible to cut a perfectly perpendicular hole with a hand drill), I made a small jig out of thin aluminum, which guaranteed the ... 
Built a Flexi-type rack?
I would like to point out that I constructed this rack about three years ago. With the wild upward fluctuations on the world metals market, I am not at all suprised by the price quotes on the raw material. Material such as copper has nearly double... 
Built a Flexi-type rack?
As I recall, the final cost of materials was right around $550 - a simple breakdown was $275 for the maple (sourced from a local millworking company), another $125 for the brass audiopoints, and around $150 or so for the brass bits from McMaster-C... 
Built a Flexi-type rack?
My "flexi" was built using 2" maple, sized at 24" x 24". My upright support rods are 3/4"-10 threaded brass from McMaster-Carr, with all brass fittings - nuts, washers and top acorn nuts. For the spikes, I used Audio Points (model 2.0AP-1OINT). I ... 
Bob Dylan's Modern Times, a new Masterpiece?
My feelings pretty much mirror Hdm's in regard to sonics. While it isn't a bad sounding LP per se, there is little doubt it spent significant time on a hard drive somewhere. While you can hear some pre-echo at the beginning of a few tunes, indicat... 
Acoustic Foam Panels - Blu Tack ???
If you have sheet rock walls, medium length common pins will work fine for smaller panels, say up to 2' x 2'. Be sure the head of the pin is secure (many plastic tips will come off rather easily), and that you try to distribute the weight evenly u... 
Power Supply Whine, Need Audiophile Help
Actually, Bob was quite correct in his response. ALL computer (read "switch-mode") power supplies have some degree of high-frequency whine. Read up on the design priciples behind SMPS and you'll discover why they make that awful high-frequncy whin... 
task lighting suggestions
My criteria for a suitable lamp was that it must be flexible in positioning, have no transformer (or any other sort of noise-producing quality, either physical or induced over the power line), and preferably NOT clamp to an existing rack or stand.... 
LP12 - identifying Cirkus bearing
The Cirkus bearing is flanged out at a 45 degree angle as it mates to the bottom of the subchassis. The original bearing is not. I think I have a picture of both kicking around somewhere. The color of the bearing well is not relevant. You might al... 
How do you clean your RCA female inside ?
If you have an electronics wholesaler in your area (NOT the Shack), see if they carry GC Electronics products. They make a "cotton applicator" (a Q-tip) with a pointy head that is absolutely perfect for female RCA jacks. If you go to the GC Electr... 
Ungrounding an Amp--Any Danger?
Defeating a three prong power cable with a "ground lifter" etc., is not only dangerous, it defeats the UL listing (Underwriter Labs is an independant body which tests electrical devices for safety under extreme conditions), and will invalidate ANY... 
Transformer noise including Powervar
I built the second link Jea48 mentions in his post, which is essentially the same as the link I posted. I kept it simple and used a piece of perfboard mounted on nylon standoffs. Everything can be configured point to point, and takes up no more th...
