So dear chakster, You can sell your Feickert and buy one plastic
caliper which you can use for all your carts/headshell combinaions.
The only thing you need to separte are your tonearms and headshlls
which you use with them.
Bad idea. I have about 10 different tonearms and about 20+ different cartridges. Feickert NG is precise tool for every turntable, cartridge and tonearm. I prefer to use universal devices and actually i paid fair price for my Dr. Feickert (well worth the investment). As i said earlier i use all geometries/alignments according to tonearm manufacturers specs (Baerwald for many tonearms and Stevenson for some of them).
I have no idea what is "plastic caliper" ?
I have Technics overhang gauges (about 10 of them at least) as a cartridge/headshell holders (here is my cartridge
with it), but for my technics turntables and technics tonearms this gauge is fine for quick adjustment. The reason is that technics tonearm on SL1210mkII (and modern SL1200G series) is not exactly Stevenson (and for this reason i use manufacturer's device, that plastic overhang gauge), but i can re-aligh with Feickert to Stevenson, Baerwald, Lofgren.
I'm not getting the Feickert because my buddy has a protractor. My plan is to install the FR-7 and hope it lasts forever.
Then all you need is correct Pivot to Spindle distance according to the FR template.
