Your thoughts on upgrading Feickert protractor

My way is get the stylus centered on the cross hairs in step one.
In step two is where I align the cantilever with the grid
Step 3 is somewhat overkill and unnecessary if steps 1 & 2 are spot on.

I find that if using step 3 as part of the main alignment procedure, is not a good thing. If you pay close attention, if steps 1 & 2 are spot on, moving to step 3, the cantilever will be slightly off. This is due to the nature of a pivoted arm. Not a major issue.

Are you serious? chakster protractor CAN'T be improved. It is already the best (grin).

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.
