Ryszard's homemade drill guideRyszard writes:
Soon it will be a year since you posted articles about my
workshop and projects
(19 March 2012).
I decided to mount the railing of the stairs in my house. For this task, you need a tool for drilling 25 mm holes for attaching the balusters. Holes need to be drilled at 90 degrees and at an incline of 41 degrees in the handrails.
After realizing such devices are available in stores, it turned out that these are very expensive. For example:
My assessment was that these were unsuitable for "Do it yourself". To purchase one of these for 42 holes would be irrational.
So I decided to make a suitable device.
The drill guide held up unexpectedly well. It is strong and rigid. The clamps can be swapped out for drilling on flat surfaces, such as stairs. You can also use drills up to 400 mm long, with the drill still positioned between the arms.
Angles from 0 to 45 degrees incline can be drilled. The stand has a drill depth stop. For drilling inclined holes 25 mm in the handrails, I pre-drilled 4 mm pilot holes.
