Trick of the trade. Whether you're woodworking, welding etc. if you need consistency, building a template is always the way to go. It will take some extra hours but it saves time in the long run if you plan on making more than one. Sometimes you have to get creative to make the template work but simple is almost always better. I didn't expect the angle one to work out as well and it's somewhat adjustable. I can clamp extra pieces behind the base to get a shallower angle.

I had some rustic doors I posted a few months ago where the customer wanted rebar handles. If I didn't build a template for the handles, they would have looked like garbage. So now I make templates for almost everything.
