@chakster, if I'm reading both your and slaw's posts correctly, Steve is speaking of the other end of the protractor: the hole for locating the center of the arm's pivot point/bearing(s).
Your thoughts on upgrading Feickert protractor
There's too much slack in the Pin hole that hovers over the center arm pivot. There should be a longer sleeve there of tighter tolerances to allow for a more accurate measure of S2P.
Your thoughts.

Ok, i just checked mine and there is absolutely no movement between the parts, metal shaft sits firmly. The latest version of the Feickert called GN (Next Generation). The Universal is an old version and it’s different from the latest NG. If you’re using an old version i must say it has been upgraded with the NG version. If you having some problem with NG version i have to say i don’t have such problem with my NG |
I have the NG and the pin eyeballs maybe a couple thousandths inch clearance to the sleeve. Not really sloppy. I have a question about procedure though. The instructions are vague, or I'm missing something. What I did, and it worked, was to set the overhang at step one while aligning the cantilever to the overhang grid line. At step 2 I moved the platter so the cantilever was parallel and on the grid line (but stylus was not at an intersection?). At step 3, without moving the platter, I checked for parallelism at the inner null point. Sounds great but is this proper usage? Thanks. |
