<div>I was trying to figure out an easier way to do the alignment on a bigger plane; since My flat table isnt big enough.</div> <div> </div> <div>I was looking around at the laser levels that broadcast a level line and cross hairs. You could measure from the laser line to the LE/TE of the wings.

Fact is, a height gage, if <BR>measuring off a flat surface used at the LE and TE is way more accurate than<BR><BR>the meters. It is quite easy to accurately measure the height off a table to<BR><BR>less than 1/32". On a 18" chord that's 0.1 degrees worst case. I think I <BR>can do better than 1/32". The key is having a flat table (not necessarily <BR>level).
You may not realize this, but what they call "silestone" is a <BR>manufactured granite that is pressed in molds. It's something like 99% <BR>quartz and some epoxy binder. It's redeeming feature is that its flatness <BR>is part of its specification and is molded in. Unlike real granite that <BR>must be polished with large wheels and they never give an optically flat <BR>surface. Silestone has actual specifications. I have a table top that is <BR>accurate to 10 mils anywhere. Way good enough for our hobby. By purchasing<BR><BR>from a stone cutter a piece that has a chip in it, I was able to cover my <BR>work table for $80.<BR><BR>Another nice thing about this investment is that this artificial stone is <BR>nonporous, which means that CA and epoxy don't really stick. They can <BR>easily be scraped off with a razor. I've even spray painted without a <BR>dropcloth and just scraped off the overspray from the table.<BR><BR>I realize this is probably a whole new alternative but I
