I’m trying to make sure the blade on my table saw is accurate in the 0 degree (straight) position in relation to the table. It came pretty straight but it looked a little off to me.
So I recently got the Wixey digital angle gauge (the 365 model). And I’ve had one of these 6” engineer’s squares for some time: http://www.leevalley.com/US/wood/page.aspx?p=32601&cat=1,42936,42941
I’m trying to figure out which one to trust. The square and the Wixey result in different blade tilts.
The problem with the square is that it’s hard to get it 100% straight on the blade and table. That is, the narrow blade portion of the square doesn’t want to stay in place while I’m eyeballing it with a light.
The problem with the Wixey is that it seems to jump around a lot. I just laid it on the table and zeroed it and the numbers on it went crazy for a while. Sometimes they wouldn’t settle down at all. I’d hit the “zero” button and it would zero out. Then it would end saying 25 degrees, even though it hadn’t been moved a millimeter on the table.
I’ve used a straight edge on the table and the cast iron table is flat, so I trust the table.
But I don’t know which (or either) of these instruments to trust. I also have an Empire aluminum try square and an Empire 12 inch combo square and a Swanson 16 inch combo square. I haven’t used those, figuring they would be less accurate than the digital gauge or the engineer’s square.
So which would you trust?
