I bought a good angle meter from either Rockler or WoodCraft 3 or 4 years ago and it is not nearly as accurate on my table saw as the registration triangles are. When trying to cut/rip precise angles for 8 sides or 6 sides, the angle meter does not get it right dead-on as the registration triangles.
I don't care if it is old school or new school. I don't have an affinity for a name. I do like for it to be dead on with no leeway. If the angle meters went to xx.001 or even xx.005, I might be happy with them. So far, this expensive meter doesn't do as well as the registration triangles for me.
Hank not sure what you are talking about. But the Wixie if used correctly is pretty dead on. If you are using a digital gauge for setting the miter I have not found one that is accurate at all. I use my Dubby cutoff sled for that which is dead on accurate. . . .
As I mentioned when you get into making things like that accuracy of the saw itself shows up too and you now add the blade in the equation and if you are using a fence, throw that in the mix also. It must be aligned with the blade. You must check all these things before committing to an an accurate cut like that.
Noooo, not a miter gauge, - Blade angle (bevels). Wixey - I think that is what I have. Been so long since I used it, I forgot the name. However, I have registration triangles that set things precisely, provide I have 2 flat surfaces to contact them. I bevel the blade, set which ever triangle I have to the surface of the saw, slide the angle up to the blade and adjust until there is perfect contact between the triangle and the saw and triangle and the blade. I put a light behind or sometimes a white cardboard behind so that I can check the degree evenness or unevenness of the contact points.
On "registration" triangles and squares: these used to be somewhat common to find, but not anymore. They are precision triangles or squares that can be used as a registration point. Extremely accurate. More so than .01 degrees, IMHO. I used the Wixey for a few times after getting it, but found that it had more tolerance for error than the registration squares and triangles.
I got mine from WoodHaven (makes heavy duty miter gauges) about 20 years ago. They quit selling them a few years ago.
