While I was working on my boat last weekend I had to run over and use my sons shop and while I was there I noticed he was setting the drift on his band saw blade/fence and using a tool I have never seen. It’s made by Carter and it works very well. I brought it home to try it and it makes for very fast and accurate alignment of the fence to the blade drift. Really beats my old method of making a trial cut and then adjusting the fence.

Here’s the picture of the tool I was talking about.

Cool!

After using this tool I’m impressed. The cut on the bandsaw was close to perfect. They are about $45 for the set which comes in 1/8” increments up to 1/2” and can then be combined to get wider but that’s for aligning a magnetic fence system to a specific cut width. I use a traditional fence system on the Grizzly so that doesn’t come into play. This is a great concept but could very easily be made from a block of hardwood and a round magnet for about 50 cents or less.

So if I understand it, the bars stick to your blade giving you the drift angle? Then you just align the fence to the bar?
