Default Segmenting Setup

I have learned to understand the curvature of the scallop based on 15, 45, 60 degree segments.

How should a blank be prepped if you want a crisp right angle without the curvature?

Use a zero degree segment.

That can be done easily enough by cutting a wedge in from the end of the blank instead of cutting a bevel off the end.

The scallop is not actually curved the outside edge is curved. This was hard for me to understand until I did several then you learn to use that outside arc to your advantage.

Thank you all - let me explain my objective.
My avatar has the square and compass ... I would like to achieve the same look in a segment.

I do realize the same can be achieved with inlays or decals. My hope was to do it with a segment, then apply the "G" via a decal. There are other masonic symbols that are similar that I could do, if this was possible.

Thank you

I think you are going to find it quite difficult to accomplish your task with segments.The reason being is because of the scale of what you are trying to do it on.I don't think there is a saw with a thin enough kerf to make the cuts and leave enough room for the segment material while remaining centered in the barrel after turning.A laser,cutting the pattern through a round barrel is probably your best bet.

One thing that I am conjuring up in my head may help you. It may have been done before but I haven't seen it. Just a disclaimer in case someone else has already done this.

If you can visualize this symbol in the center of the pen, first cut your blank into thirds. Take the center section and make the V cut for the square. I would use some light wood like maple so that it looks like a ruler but your could use thicker aluminum. If you haven't done segmenting with metal, you have to rough it up with 100 grit first so the CA can grip it. Segment it and glue it all back up and let it sit at least overnight. Square it up then cut the compass V. Obviously it will be at a more acute angle. Lay in some aluminum and glue it all back up again. Let it sit for a couple days. Now, sand the sides of all three pieces lightly to ensure straight lines and glue all three back together. I think when you turn it you will end up with a reasonable symbol.

You can also play with putting in some other kind of wood to get the symbol center a different color. There are a lot of options to play with. Let me know if you need any more thoughts or guidance. This is just want I visualized I would do if I were to try and do what you are trying to do.

Good luck!

And the top of the compass, you can just drill a hole and put in and aluminum nail or something. I would drill half way thru from each side so that you make sure it is at the point.
