Two errors in the Porting and two ways to fix.

It happens that like ten times checked, marked out, drill a hole, and then it turns out (damn it!) In the wrong place.

What I like to work with wood - the fact that everything can be easily corrected in such situations. Wood pleasant, responsive, plastic material. In place of chips, of the separated knots can be done by gluing and strength and post-treated to place it will be virtually indistinguishable from the whole portion of the preform.

Which of the two errors in question.

The first situation, drill a hole in the wrong place. This can be a significant shift in direction - a few centimeters, and here the decision easier, or maybe shift a few millimeters here to correct a bit more difficult.

The second situation, broke the sequence of drilling. For example drilled to drown bolt and threaded drilled first, and when you try to drill under the bolt head, to drill no support and it just breaks the hole.

Ways to fix.

According to the first situation, but rather on its first part is simple - in the wrong hole plug is glued, sanded, puttied and after painting it will not notice. Especially if the plug is not cut from the end and, on the plane and a similar texture.

(About the manufacture of such plugs - a separate issue)

On the second part, when the shift a few millimeters of the difficulty lies in the fact that the center of the right holes can be near the edge of the plug and porting drill may easily come off at the edge and still get an erroneous hole.

In the second situation, the same problem - to drill the center there is no support, because the center has a hole and the tip of the drill bit will inevitably sidetrack.

In two extreme case a good solution is to use a simple jig for porting.

For example, drilled through hole 6 mm., And must also make a hole of 15 mm. Then take a scrap fanerki drill through 15 mm. tsentruete and presses the clamp fanerku drilled over six millimeters and drill.

That is, this pattern works as a guide for the drill.

The same way you can do shallow oval holes.

Put huskies and write comments, I will be glad to communicate.
