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.

if steps 1 & 2 are spot on, moving to step 3, the cantilever will be slightly off 

Feickert suggests that If the cantilever is slightly off at step 3, it is telling you steps 1 and 2 are not spot on. 

Step 3 “check parallelity with lines on the inner null point.  In case 
parallelity doesn’t match (step 2) go back to (step 1) Otherwise planar setup is finished.
I like my SMARTractor. Except they should have put Stevenson alignment on also. 
@wlutke,

Not my experience brother.

Not what is written either.

Funny how at first you seemed to be questioning your own set-up, now you’re questioning mine.

If you knew, why ask? I’m out.

I recognized your moniker from the VPI forums..... so I felt like I was being set up. Just wanted to see how far you’d go?

You should try a MyMat. Then maybe you'd spend more time listening.
Calm down.  Not a setup at all.  Your info conflicted with the instructions and I pointed it out.  It’s a discussion, not a judgement.  With an open mind I had hoped for clarification of your opinion about the nature of tone arms. I thought the Feickert instructions vague.  Still do.  btw my moniker at the vpi forums is not wlutke.  
@wlutke ,

I'm actually enjoying my VPI now that I found and fixed most of the manufacturing defects.

Peace
