Finally did it ! The mighty center finder! I took the approach of making the studs and pin out of steel. That was a lot harder that i thought it will be. The 3/8 steel rod is not easy to thread at all. The pin is threading them shaped on the drill press with a file for the pointy tip (that was easy and actually fun). The purpleheart has proven to be very unpleasant to work with, however it did thread ok. the Koa wood was easy to work with and relatively soft. Big disappointment in the $.95 brass insert : almost exploded in the hole and broke on the top. Overall all a big learning project, result is ok but “off” by about .007” due to bad threading on one rod. Next one will be better (i hope..) Cheers.

Turned out pretty good after all the issues you had .
For you next one you may want to try this one
I designed it because I got frustrated with the two pin one because before you get to the end of the board it slips off and have no line near the end .

Really fine work.
Learning is what this is all about, next time it will be spot on. ;-)

This is a very handy tool!

Just curious, why didn’t you make your guide post by cutting the head off of 3/8” bolts? I use 3/8” steel rod (actually center less ground rod) for various things and as you point out, it is a real pain to thread. I wouldn’t ever want to do it unless I had to…..

thanks guy for the comments. I really dig the mix of metal and wood, a lot of different expertise there.
@Splintergroup : good question “what did possessed me to use still rod ” Answer : “honey, i don’t think you should buy more stuff for your projects, use what you have, please ” :-)
