You have to plywood to win....... so where are all the guesses or better yet someone who knows what these are. They were sold as a pair but you might only use one..... hints enough for now.
No but you are getting warmer....... perhaps another hint. It has something to do with a saw kerf.......ejant said:Plywood thickness guage for checking to see if the plywood is actually the stated size. You could probably consider it a go-no go guage.
Good detective work! Yes you can slid one or two of these in the kerf to keep the plywood/simular material from tipping and closing up on your cut. I end up mostly working alone since the kids grew up and left so they come in handy.Dr.Zook said:Ed my guess it fits in the saw kerf when you cut a full size sheet of plywood. This keeps the kerf from pinching shut while you rip the sheet. Just a guess.
