I asked the same questions when I first started and got excellent responses.
On #12 Bill Young gives the Dropbox link for his original design.http://www.talkshopbot.com/forum/showthread.php?19057-Desktop-Jigging-Pics&highlight=desktop+jigging
1.5" spacing and his fences/jigs have dowel spacing offset by .75", so the workpiece always winds up at an inch increment.
I just added inserts equidistant from his reference dowels so stuff can't shift and dowel holes don't gradually get out of round.
Yep, Shopfox from Amazon, but throw is very limited and need to make some eccentric cam clamps for myself for a larger/faster throw.
Spoilboard file to big for on here because I have a bunch of stuff in No Man's Land because I had to rotate it to Tile through my Y axis.
Likewise with his "fences and jigs" file as I have his originals/my stretched ones with bolt hole drilled and counterbored for Fastenal Connector bolts(Nice flat profile,no washers needed,and Allen key is simple/fast), so messy, but I just copy/grab what I need and put it in the field and nest them.
Have used Adrian's nylon bolts and saved me twice:)
