Woodpeckers Protractor (ruler)
« on: April 11, 2023, 04:49 AM »
Recently Woodpeckers released the protractor for the t-square as a onetime tool. This month, they released the same type of protractor but then for the rulers. I decided to buy one of those, hoping it could fulfill the following:
  • Repeatable angles
  • Easy measuring the length of an angled corner from the start of the wood till point X

To start with the good things, it came well packaged and fits like a charm on my existing rulers. There is a slight height difference between the ruler and the part of the ruler that is connected to the protractor, but that is not really important. Just as Woodpeckers claimed, the protractor arrived calibrated in exactly 90 degrees. Changing the angle is easy by loosening the 2 knots on the back. Woodpeckers made it so that when flipping the protractor, the angle stays the same.

As far as the cons go, I wasn't able to make repeatable angles. For me it was very difficult to place the indicator exactly on the line. Even a hair of, results in a different angle. In the end, I ended up sawing some pieces of wood using my TSO MTR that has the option to pin different angles. Using those pieces of wood, I set the right angle for the protractor, but this beats the purpose of the protractor.

All in all, it is not what I hoped it would be.

That's unfortunate... [sad] ...but getting good repeatable results without using positive stops is always problematic. I used a Vemco drafting machine for years and that was repeatable ONLY because of the extra vernier scale next to the head and even then you still had to be very careful.

Those reasons are exactly why I purchased the Woodpeckers Posi-Lock T-square with positive detents every 5º. It may not be as versatile as the one you purchased but it is repeatable and fits my needs.

If that also works for you, consider talking with Woodpeckers to work something out, it's worth a try.  [smile]

Appreciate the review.  I am currently in need of a protractor that I can lay flat atop my boards and was almost ready to place the order for the Woodpeckers head.  I also looked for other options and instead, settled on the Starrett protractor head to use with my Starrett rules which I have in 12", 18" and 24" lengths.  The head may not be as large as the Woodpeckers offering, but it's tough to beat Starrett precision and quality.  I doubt that it would be any more repeatable than the Woodpecker head, but the ability to set the angle as well as the distance the ruler protrudes from the head will be a plus for the Starrett.

I don’t have an immediate need for a protractor, but I did some research a while back.

The Shinwa sliding bevel seemed to meet my woodworking needs.  They will lock positively with a thumb nut.

Ships free with Prime from Amazo.com at just $49.00.  It is designed for woodworkers and made in Japan when I checked a couple of years ago.
