Ever since I got my Carbide 3D flip jig, I’ve been curious to figure out a more universal strategy of doing flip jobs. I thought since I have a sea of holes bed with holes every 1/2" and the repeatability of returning to the center of the bed I’d just drill holes to serve as registration and holding the stock. Using the x and y middle of the bed I drill holes equidistant from the center and in theory I should be ok, right?. Yes, but not perfect. I’m not getting perfect registration and I’d love your opinion on this. Here is the setup:
Drilling holes for registration based on 1/2" spacing for tapped holes in bed
Place threaded rods and spacers at the appropriate holes in bed to align with the holes drilled.
Setup my job with the zero at the center top of stock
In theory it should all be ok, but it’s not perfect alignment. The holes fit very snuggly around the threaded rods and there is almost no play at all once in place.
Here is a closeup of the misalignment.
Any ideas why?. Suggestions?. Rods maybe not perfectly perpendicular to surface?.
