I am trying to miter this piece of wood (one side that has a curved surface). My problem is how would I measure the wood to be at the end using the 45 degree angle. I realize now that I should have just cut the 45 degrees at the beginning instead of pre cutting the wood. Here is the picture of my saw as well as the piece of wood I am attempting to use. Any assistance would be greatly appreciated. Thank you LueyD -- LueyD

Most likely a better way to do it but if I was in a hurry thats how I would do it. Gary9124 posts in 3214 days #2 posted 07-11-2014 06:20 PM a quickie note…. If you measure the thickness of the board and go back that far from the front, you will have a 45 If it’s 3/4 thick, measure back 3/4 from the front. -- Gary, DeKalb Texas only 4 miles from the mill BinghamtonEd2286 posts in 2151 days #3 posted 07-11-2014 06:21 PM I would ditch the fence and attach a backer board to my miter gauge. Run that over the blade without the workpiece to create a kerf. Mark the cut line on the workpiece, then line it up with the kerf in the backer board. If you have multiple ones to do, attach a stop block to the miter gauge board. -- - The mightiest oak in the forest is just a little nut that held its ground. lew11757 posts in 3536 days #4 posted 07-11-2014 06:22 PM A 45° degree triangle has equal length sides (A & B). If you measure the thickness at the “high point” then measure back from the square end the same distance. Draw a line from that point to the edge and you should have the correct distance. Just to be safe, cut a little proud and do what Richard said. Also, be careful of kickback cuase it looks like you’ll be hand feeding the piece thru the blade. -- Lew- Time traveler.

If you measure the thickness of the board and go back that far from the front, you will have a 45 If it’s 3/4 thick, measure back 3/4 from the front. See I told you there was an easy way to do it. This was taught to me way back in High School but I just forgot it in the long absence from woodworking , Now if I can just tuck this into my brain and not forget where I put it this time.
