Dealmonger: Center It Hole-Drilling Jig $12.90

Aircraft Spruce and Specialty is selling the Center It hole-drilling jig for $12.90. The jig allows you to align a drill bit with the center of the vee-block jig, then place tubing or round stock in the jig and drill a cross-hole exactly on center — a pretty handy tool for work like this.

Very similar design (though obviously a little cheaper, $9.99 NOT on sale)… I’ve had one for quite a while (got it on sale at HF for 4.99), and the couple times I’ve had need to use it, no complaints!
I guess it might be worth it if you don’t have a welder, it would take seconds to make something to do the same job with scrap steel laying around most shops
