[QUOTE=robertandsons] The question is, did StewMac consider the center of the saddle
when they configured the compensation?

Lets see:
0.156 and 0.062 make for 0.109 at the front of the saddel in the middle (between D and G strings).
The saddle is 3/32 thick = 0.09375"
The center is at 0.0469"
The compensation at the center is then 0.109+0.0469= 0.156"
Cumpiano recommends 0.15" and this is what I do also.
Your bridge is off by 0.03"
I would say you are OK but your saddel top will be like this   D instead of this O

[QUOTE=BarryDaniels] One thing that has not been mentioned is that when the bridge shifted, it likely had one edge that lifted up over your finish resulting in less than an optimal fit of the bottom of the bridge to the top where you scraped off the finish. If your finish has any thickness to speak off, then your bridge may not be well glued to the top now. [/QUOTE]

Barry brings up a good point. However, your Tru-oil finish is probably whisper thin. If you didn't scrape down into the spruce, but only removed the finish, that couple of mils of finish thickness shouldn't have any effect on the glue joint. Lots of builders scrape (or rout) off the finish a smidge inward from the edge of the bridge outline and glue the bridge on overlapping that little bit of finish around the edge. Some rout a very shallow rabbet around the edge of the underside of the bridge, but many don't do this and don't have any problems. Again, if your finish is very thin and you've been careful to remove only finish, not wood, when scraping, the glue joint should be fine.

Barry, after I read your post, I went out to the work shop to very closely inspect the bridge.
It appears that the optimal fit has been achieved. I could not find any gaps to speak of between bridge
and top. Also, the finish is so thin, it’s barley detectable. After scraping off the finish in
preparation for gluing up the bridge, (out of curiosity) I laid a straightedge on the top, centering
the scraped area. I could not see any gap whatsoever between straightedge and the scraped area
of the top. This made me feel pretty good about the finish. I’m thinking I did it right!

Alain, the math makes sense to me. When you say that the saddle will be like “D” instead of “O”
Are you saying that the vertical line of the “D” would face the sound hole?

Todd, I did exactly as you have described.

Hesh, maybe you could do a tutorial on “First Tune Played at String Up”! With lots of pics! I for
one would enjoy the towel bit!
But, if you’re going to do the “Flying Nun Song” perhaps Lacey could hold a fan in front of you
so we could get the full effect!

Yes exactly.

How can you tell if you got the bridge in full contact with the top by looking at it with the bridge attached? Your finish only has to be a couple of mils thick to cause a wider than ideal glue joint. You may be fine and the bridge may cause no problem. Then again, this could cause the bridge to peel up prematurely. Only time will tell.
