Thread: Cutting a 90deg into sheet

I think you are on the right track. I would use a jigsaw to cut the lot, using a timber guide clamped to the workpiece to get the cuts in a true line

so there isn t any more precise techniques?

Hi Vicente, and welcome.

You could use a router with a template following bit, that is a straight bit with a bearing.

Firstly rough cut the waste out inside the line.

Clamp a straight bit of timber on each 15cm line so the gap between them is 2cm. Clamp a bit of timber in between to line up with the end of the cut. Now your router will run around the inside of your timber guides giving you a perfect edge. You will still have to tidy up the internal corners with a sharp chisel.

If you are doing several of these notches you could make a jig which you can reposition for each notch.

Vicente,
How about making up a template, clamp/screw/hot glue/ it in place and then use a small diameter flush trim router bit to cut out the body of the waste then use a chisel/fine saw to square up the corners. You could use the jig saw to remove most of the waste just keeping a couple of mm for the router to tidy up.

What material is the pin board made from

If you search for "Ron Fox wood working" in Google videos you will find a series of videos which show you exactly how to do this, using a template following router bit. In fact these template following bits are one of the most useful router bits you will ever buy. For example when you get an 8x4 sheet of material it is too big to breakdown initial on a normal table saw. But you can use the template bit to accurately break down a large sheet into smaller more manageable pieces.

To me when you say pin board I think of canite Sp? If that's what it is then I would be using a Stanley knife.
