if available at a good price, there's always something one can do with the stuff. brass can be troublesome, esp if it's cast. in sheet form, it should be ok to engrave. i have had little trouble working the stuff in sheet form. then again, i never knew specific alloy info.
the centenial brand was very good for me. one had to grind a flat to allow indexing for sharpening. it can only be shaped with diamond or special "green wheels". ordinary grinding wheels will not work for carbides.
i failed to mention that some of the old engraving books are free on the net. the entire book can be enjoyed on your computer, one page at a time. one can even print some of the pages. i don't think there's a copyrite problem. you can get them using google.
uh, well, prettty much what they all said. the texture and flow in the portrait is unbelievable !

trying to layout...
way to go on #3 ! a friend has a 172 he has access ( 1/3owner ) to.every now & then it's nice to leave the neighborhood for a couple hours. be careful, you may enjoy flying more than you do engraving
"stuff" like that may surprize you. might work very well. or may need a great deal of tlc. one way to finf out, take a chance if it's reasonably priced. i've seen quite a few home brewed ones. none xactly like this one.
i use an old 1.5" dia. lead screw and flange. such allows me to adjust the part easily to the focal point of the scope. the scope never needs adjustment. all are comfy for me when seated. easy for me, as i have a couple of welding machines and cutting torches.
all this is attached to a "scope...
if there's a decent scrap yard near you, you'd be surprized what may be obtained in such a place. the yard where i buy has all manner of ss there. if you like, i'll check and let you know if there's some 302 there.
