some more barrel jeweling

I'm also from the "60's" and raced on the streets as well as Westhampton, NY national & Islip drag strips, and yes its done the same way as gauge panels, only difference is I use a machinist drill press vise and have found that a quarter turn on my vise positions it for the next jewel, and you are correct we did call it engine turning. I don't make a living doing this, just like to play around and make my stuff a little different. A couple of things if you want to give it a try, the surface you plan to jewle must be polished to a high luster, next I use vale grinding compound 120 grit, wire wheels which I put heat shrink on so they don't flay out, or I use cratex wheels in a holder, these work good on a flat surface, this was my first rounded surface so the patterns are different than the jeweling on the LC9 & the S&W 629 hammer & trigger. In the 60's on flat panels I remember using 320 grit wet/dry sandpaper on the end of a dowel rod, do remember using valve grinding compound back then as well. As a matter of fact I still have more than 3/4 of a can of the same stuff that I use now.
