Bench Dog 10-030 Bullnose Trim Gauge

Definately the way to go if you have bullnose corners and replacing base moulding or doing crown. Saw it recommended on YouTube and had to get it for my house with bullnose corners. Simple to use and cant go wrong.

Great time saver! No more having to mock up a corner to get your measurements.

Simple, effective tool to allow accurate, tight bullnose miter joint cuts at a great price.

This is perfect, exactly what you need when looking for the right measurement for doing base board. I do many many feet and this little guys makes it faster.

Product only accounts for a bullnose with a radius of 3/4 where the transition piece is 5/8. However, rounded corners on my house apparently have a radius of 1/2 so transition piece needed to be 7/16. This threw the math off for both left and right pieces. I ended up using trial and error along with wood putty to fill the gaps. It would have been nice if there was any indication in the description that bullnose corners vary in sizes. This also explained why when I put the trim gauge up to my corners, there were gaps under both sides as they did not sit flush with the corners. I only learned of different bullnose sizes after watching a video showing a cheat sheet. For radius of 1/2, transition piece is 7/16. For radius of 3/4, transition piece is 5/8. For radius of 1, transition piece is 13/16. Finally for radius of 1 1/2, transition piece is 1 1/4.

... the break for the cuts, but youll need to be a craftsman to make the cuts tight. Ill bet your house does not have a single 90* outside corner in it, and that is what you must have, a true 90, for this gauge to do its job. Then youll need a saw that can cut an accurate 22.5* angle both left and right. And the 5/8 throat is rare. Most bullnose bends are 1/2. This device does however, make a great pencil tray on my work bench. Keeps those suckers from rolling off the table and breaking the leads.

Marking the corner on a bullnose corner usually takes more hands that I have. awkward. This tool makes it easy.

Husband loves it. Made the job so simple.

Saves time and is accurate. The corner piece is usually 5/8 short point to short point. To me its worth the small price tag.

The first few outside corners Id tried to cut without this tool, was an exercise in frustration and cursing. Making them with this tool is easy. Once you get a couple corners under your belt with this, youll breeze through them. Was able to trim baseboards around a column with 9 outside corners in roughly an hour. I was ready so sub this work out until I got this tool.
