Thanks guys, haven't touched the blanks yet as I've been wrestling with the fingerboard.
It only took 4 goes and about 8 different rigs to finally get it setup right.
So I've persevered with the Tassie Oak, because its easy to get and cheap. Getting it down to a reasonable thickness without springing $500+ for a thicknesser was a bit of a challenge. I ended up using some aluminum right angle and mounting it directly to my router table to make sure it was as flat as possible. Dressed one side, with the router, then flipped and dressed the other. I just held it in place using the superglue and masking tape trick .Board ended up just on 8mm thick from approx 12mm as it came from the big green shed.
This setup is also exactly wide enough to put my radiusing block in so I can remount the finger board in there and do that a bit down the track.
Anyway some pics. I'm happy with it. The slots are not quite at finished distance, I'll wait until I've added the radius and then give them a final run through with the kerfing saw.
I'm so happy and relieved to be at this point now as being able to successfully make my own fingerboards has been a bit of a road block for me to this point.
