Worldcruiser,
I really like your scarf jigs, especially the spar jig ! I have been trying to work out the best possible way to handle the large spar scarfs and you look like you have got it down just right !
For my ply scarfs, I am using a John Henry attachment for my planer. It works very well on the ply and with the addition or removal of spacers can attain any number of scarf ratios.
