I was in Lowes to get a sawsall blade to make a thin parting tool. While looking through the tool section I come across a cheap sliding T bevel for less 5 bucks. I ground an under cut off of the bevel and will touch it up when I get home tonight and give it a try. One slot in the handle is longer that the other so I've got the short slot in top so the blade presure will be upwards into the handle, I believe that I can tighten the one bolt enough to make it hold tight, we'll see.
Anyway, just wanted to pass it along and I'll follow up when I give it a try.
