Fixed Angle Jig

 

For use with the Wood Owl 1/2 inch bit...this jig will be used on resultant angle sightlines to make holes for staked furniture builds.

 

This bit is 7.5 inches long and cannot be used at the drill press for this process.

This jig will enable the bit to used in a hand power drill at the proper angle.


 

Using an oak blank...drilled a 1/2 hole at 15 angle at the drill press.

Inserted the 1/2 inch Wood Owl bit through the angle jig...placing the lead screw on the mark...

Brought the prototype 1 jig down to the surface...aligned the front mark with the resultant angle sightline...removed the bit...

Secured at bench and drilled out the hole...worked reasonably well but jig is huge...need to downsize.
