Adding up all the various costs makes the entry level Teres turntable more attractive. By the time you buy the motor and bearing and the platters (from TAP) it is about a grand and that is without plinth or an armboard.

The Teres Platter is only 2.75" thick. TAP Plastics is NOT a CNC machine shop and *I* wouldn't trust the accuracy of their cuts since they do everything by hand. If you want a truly round platter, CNC is the best route. Acrylic can be purchased in 4" (which is actually 3.93701") thickness at San Diego Plastics http://www.sdplastics.com/sdplas2.html If they feel the job is too difficult, they will sub-contract to a CNC Machine Shop. * machining a platter is more complicated than just making a round piece of acrylic. Chamfered edges - far edge rounding/chamfering are required for bearings to fit into and rest flat in bores. Connecticut Plastics is a higher precision option and can be found on the web at: http://www.connecticutplastics.com/ They prefer to receive high quantity orders but may help you if you claim its a prototype. Flame polishing is almost mandatory for a pretty looking platter. All TAP Plastics stores do flame polishing and so does San Diego & Connecticut Plastics Hope this helps. |
You really don't need a CNC machine to make a round platter. A lathe or bandsaw will do the job quite nicely. I prefer the bandsaw. Just cut the spindle hole on a drill press then use it as a pivot point to rotate the acrylic through the bandsaw blade (use a narrow blade like 1/4 or less) and finish per the Teres instructions. |
