  What a neat way to view fringes, projecting the laser reflection. Never seen that.

  I am so glad I came across this video today.<br>Im doing some lapping plates atm myself and was debating on whether i do pretty much the same design as you have but now seeing it done gives me motivation to go with that style

  My eyes bugged out when you said &quot;40 millionths.&quot;

  How does one go about removing the embedded/charged abrasive particles after the plate is made?

  Awesome video! &nbsp;And perfect timing, just when I thought I&apos;d watched all of the lapping videos on youtube the past 2 days ;-). &nbsp;Time to make some plates!

  Interesting optical flat setup, can you explain how you built laser apparatus more so that it can do optical flat inspections? Thanks. Also more details why only 2 plates are needed and not 3?

  I heard you&apos;re coming to Kern for a semester? Are you coming to Germany?

  Would the rounding be less if you held the part in a V-block while lapping? With both the V-block and the target part touching the plate simultaneously? I suppose it would take a lot longer though due to the extra surface area.

  Can you lapping on them diamon and silicone carbide for like f2000-8000? For natural stones

  It looks like the grooves are tapered/beveled. I assume that’s to encourage the abrasive to be drawn in between the plates. Can you confirm this and maybe elaborate a bit? Thank you for this video!

  Excellent video. Would you mind putting a link to the reference video by Spencer? I can&apos;t seem to find it. Thank you.
