Just a heads up, I got my Mintlp Protractor today.
First time I ever got anything for Hong Kong in my life, and perhaps Yip should offer a side service, where he could ship me in a few bottles of some really good Chinese Oyster Sauce! lol Yummy!
Anyway, all arrived intact, Yip did a fine job of packing. I like the lighted magnifier, much smaller, and probably easier to use, than the huge affair I have on hand.
I like the personalized flair that Yip sis with these, it's made "especially for me"! The 211mm AQ PT Arc will work for both tables I have.
So, I'm looking at the Protractor, and saying to myself, ahh, a nice fine Arc line, but I only see just two lines on the Null Grids. Hmm, I thought.
Yanking out the 10X Loupe I have, I look closely at the Null Grids to discover two thicker lines, and three very fine lines in between, plus a very minute Tic, right on the Arc, which it where the Stylus must be placed.
While I haven't done the alingment yet (I know one must be prepped, and in a very happy mood before toying with anything like this) It looks to me, that Yip has made a very good product, with very high resolution.
It must be this ultra-fine resolution that sets his Protractor apart from many others avaliable.
Hopefully, I'll find a correct Spindle sized hole when I begin. I'll write again, when I can offer more to us 'Goners here. Mark
