So here we go with another try on this post.
I wanted to post a few pictures of some cheap, but very helpful tools that can be easily made. They have proven to be worth the effort in terms of accuracy and ease of operation. I’m sure there are many more designs and ways to do things, but these have worked well for me.
The scribe, or marking gauge, in the pictures was made with scrap wood from my shop. The metal, the bolt, and the thumbscrew were bought cheap at Home Depot. Any hardware store should have them. The holes for the bolt and thumbscrew were drilled out then tapped with an inexpensive tap from a local lumber store.
In operation, two hands should used to keep things steady. (I had to hold the camera with my other hand). You can also clamp in a razor blade instead of a pencil if you want to cut tape.
I use it to scribe a faint line on the edge of the board so I have a good line for my first run of tape for pinlines.
I have few more pictures to follow. I hope these will be helpful. Doug
