    well duh......

    @ me.......

    Been practicing mortises ----- and could not for the life of me, figure out why I was coming up - typically 1/8" off the target mortise width of 1/2".

    Well - after scratching my head --- measuring - re-measuring - and groaning for awhile - I found the missing width ----- it's the kerf of the saw blade!

    I've been using Kreg setup bars -

    The plans call for cutting off 1/4" - so I grab my 1/4" setup bar - and gap the blade - then cut. I'd forgotten to count the blade kerf ---- which would add to the measurements.

    Well, now that I've figured it all out - I'm hitting 1/2" mortises on the head.

    Good news is --- I've been using scrap wood to practice with!

          That's not uncommon. Getting used to figuring "save", "waste", and kerf gets familiar.

              Glad you solved your mystery.

              I started the habit of marking an "x" on the blade side of the cut line when I mark out a cut on the stock. That way, if I use a stop block or some kind of setup bar, I can make a "pretend" cut and see where the blade is relative to the cut line.

              I have fewer 1/8" and 3/32" mysteries since I started doing that.

                  That's a good idea. I teach my scene design kiddies to put an arrow on the waste side pointing to the line. Didn't stop me from putting a 3/4" dado on the wrong side of the line though.
