MattSA Posted October 14, 2018 Report Share Posted October 14, 2018 (edited) When sanding a flame-top guitar is the grain perpendicular to the flames, or parallel with the flames? When I look at this picture the most distinguishable flames are horizontal, but there are definite vertical configurations as well.

Norris Posted October 15, 2018 Report Share Posted October 15, 2018 On most guitars the grain will be in the same direction as the neck - it's most stable that way. Flames will usually be (close to) perpendicular to the grain i.e. top to bottom of the guitar. However the figuring can run either way - if you think of quilted maple Quote Link to comment Share on other sites More sharing options...
MattSA Posted October 15, 2018 Author Report Share Posted October 15, 2018 Great. Looking at the picture then would you consider these flames to be running perpendicular to the neck or parallel? Quote Link to comment Share on other sites More sharing options...
ScottR Posted October 15, 2018 Report Share Posted October 15, 2018 The flames are are running perpendicular to the neck (and likewise the centerline of the body), and the grain is running parallel to the neck. The vertical lines you see are the grain, which is actually the rings of pores that are the growth rings in a tree. In figured wood like this the pores do not run in a straight line up the trunk of the tree, but rather in a wavy line. The flames you see are in reality rows upon rows of wavy pores--think tubes like soda straws. Lined up side by side the waves create the visual you see as flame. Think of a package of ramen noodles before you stick them in the boiling water. So the grain is going north and south and the figure is going east and west.

MattSA Posted November 4, 2018 Author Report Share Posted November 4, 2018 Can someone tell me if it is dangerous to use grain filler on a figured finish? I am worried the filler might inhibit the display of the figure. Quote Link to comment Share on other sites More sharing options...
Norris Posted November 5, 2018 Report Share Posted November 5, 2018 Have a look at this tutorial... It has some good tips on preparation. And also... Usually a figured maple would not require grain filling. However you can get clear grain filler if you really need it Quote Link to comment Share on other sites More sharing options...
