Vertically driling jig

[devonwoody]

Seeing the Rutland spam this morning re their vertical drilling jig gadget, I thought I could make one of those.

two identical strips of strap flat steel sealed into position with masking tape and drill your series of diameters.

Separate and fix to a flat length of batten the steel drilled pieces top and bottom, cost under one pound.

I saw that two and thought you could actually make one in wood if you had a pilar drill. Admittedly it won't last forever but for the sake of drilling some holes in some off it's occasionally it would be fine.

Those things are also useful for hand-tapping a thread. Providing the tap closely fits through one of the holes it will start the tap perfectly at 90 degrees.

If you can't drill vertical...........

I was going to make one myself but in the end I bought one of these. Amazon now sell them.

I usually do that on the pillar drill: take a drive belt right off, and hang a weight on the handle to counteract the quill spring. Turn the chuck by hand. Advantage: I can see what's happening.
