My first project with the SCM combo unit will be the making of a wooden soccer ball which is made up of hexagons and pentagons with very precise mitre cuts for the joints. The guy whose U-Tube video I am following gives those angles to three decimal points! What is the most accurate angle finder out there- regardless of cost. All I see are these $30 devices which seem to be made in the same factories with different labels on them... thanks!

You have the Mitutoyo protractor which are super accurate (but the once who will give you 0.01deg resolution costs over $1000)
Before getting such an expensive protector I would probably use the less accurate devices that will give you ~0.1 deg accuracy and made the cuts 5/6 times on a scrap and see if the align to an hexagon and make the micro adjustment there?

That’s easy. ?Bridge City Tool Angle Master Pro. ?It’s the tool I have and use for this kind of thing. ??Watch this - skip to 1:00 in the timeline. ? |
Here's a screen shot from my iPhone app that goes along with it.
Or you can use the web interface: ?https://bridgecitytools.com/pages/anglemaster

Not on their website- ?seems like it is NLA

Did you read my previous post - ?I linked to it in my first reply. ?They come up on eBay about every 2 years. ?
You could also consider this. ?I have one of these too. ?Make me an offer:

Once every two years?
I don't think those protractors are accurate enough...

That’s funny - I’d love to see you consistently set and cut compound angles on your sliding table saw more accurately than that Mitutoyo protractor can resolve. ?What a joke.?
The Bridge City Angle Master is highly sought after and has cult status. ?That’s why they are so rare. ?I guess you still didn’t read my previous past. ?Good luck.

I have the Starrett version of this - bought it a few years ago on EBay for ~$300 IIRC. It is a little fiddly to set up, but once that’s done it is incredibly accurate. I use it regularly to dial in parts cut on my CNC mill.
Question, David: do you have a manual, (or link) to you. Mitutoyo? The Starrett version is about 1/2 page, and basically assumes that if you have this thing, you should already know how to use it.

Gerry- which Starrett product are you referring to? ?If you are referring to a protractor type of gage,
then is simply not accurate enough regardless of what has been stated here. ?For the application that
I am using it for, the tool has to be used to reset a variety of angular dimensions.

Accurate and repeatable to an accuracy of 0.08 degrees. ?

It was just too far gone and and support for a 25 year old machine was limited and I did no want to wait around for some unknown period of time hunting and? pecking for parts.
Same Blasco made me an offer I could not refuse on a cu300C

I have used that General Tools Angle Protractor #17 for various things.? I have also used this General Tools Angle finder #39 for things as well.? They work well, even if they are not super precision.
I also have a set of the Bridge City Tools UG-1 Universal Gauges that I have used as well.? They are very nice:

Just did some angle measurements this am a on staircase parts with 100 year old Starrett. Becomes very easy with I phone 14 camera

yup that’s it - Starrett #C359. It don’t think they make it anymore. Mine also came with the optional right angle thingie, that attaches to the bar with the logo on it. The right angle attachment is useful, but increases the complexity of the setup, if needed. I use it at least weekly, to check the accuracy of angles cut on my CNC mill.

Nothing beats a sine plate, although not very practical for woodworking. All of these bevel gages are not anywhere close to accurate enough at 5 minutes of a degree. The Bridge City Gizmo is going to give you the best angle setting for a relatively easy to use jig that is applicable to woodworking, as it is basically using the sine plate convention with a digital caliper instead of Jo blocks.

I would love to see one of those bridge city devices, but alas…
So no one who has responded uses one of those digital devices?
