Guitar Fret Board

I've started to move into guitar production. With school ending soon, by opportunity to use a large CNC is also ending soon. I figured I'd do the pieces which were the most difficult to machine first so I might have a hope at finishing the leftover parts during the summer.

Using 2 vises is GENIUS! They made the setup much faster than if I had bolted the part to the table. I left them on the machine (usually there is only 1 per machine in the school shop). I'm pretty sure others will appreciate not having to unbolt the vise anytime they want to make a part larger than 8" wide.

 I missed a bit of the surface while facing the top. It really didn't matter because it would be almost completely machined away while cutting the frets. The fret marker screws were cut perfectly so they would be flush once the frets were machined into the board.

The pattern from the tool path looks really cool, so I've decided not to polish the fret board. It isn't really visible in the picture, but all of the frets were rounded with a corner rounding endmill.

I hadn't machined any stainless in a while, so I forgot how painful it is to machine compared to the usual aluminum. The machine really wanted flood coolant, but I didn't have that option since the machine wasn't fully enclosed. Next time I'll make sure I use a full machining center when I go to make a big stainless steel part like this. I was also too lazy to do any bit changes so all of the frets with a 1/4" carbide end mill. It just slowed down the process to the limit of my patience.

Also I've just about had it with my cell phones camera... the pictures it takes look like crap. I swear they get worse every day. I'll probably go back to using a real camera instead.
