Awesome tool!
This made bullnose corners so easy. I was a little intimidated at first because I've never done baseboards before and every outside corner in my house is bullnose. I highly recommend this little tool.

Chris L on Feb 4, 2019
I tried to buy the precut round wood corners for my stained baseboard but the stain shop couldn't match the color of stain on my hemlock baseboard since the round corners are poplar. I gave up and will cut them from the baseboard stock but didn't want to guess on where the corner starts. This should give me a line to measure to. On line videos of how to cut the 22.5 degree cuts was helpful

Using the bullnose trim gauge...I line everything up and fits great. When I nail the midle bullnose piece, it shifts and is a little off. Happened 5 out of 5 times. What am I doing wrong?
Bullnose 5150 on Feb 24, 2017
BEST ANSWER: Just nail the side pieces and glue the center piece to the sides. Nailing into curved metal can cause the small trim to shift.
will this tool help with 22.5 degree inside and outside pieces?
rob w on Dec 26, 2017
BEST ANSWER: Yes. This tool makes bullnose corners easy. Just follow the simple instructions and you can’t go wrong.
Can I use this tool to cut out the middle piece?
Bruce on Aug 31, 2017
BEST ANSWER: No, you can't. However, the instructions are very clear on how the piece needs to be cut.
Will this work on square corners not bullnosed?
DAVID K on Feb 16, 2019
BEST ANSWER: No
