All of what Fitz offered....I have a rack puller that I ground to have thinner flat surface at the claws and sharper. It is easier to get under the heads and supported with the putty knife does little if any to the planks. But when removing the rib I snap off the clinches using one edge of a sharp claw point and hand poke or tap the shafts out as Fitz does. I measure for a new rib and fashion one a little longer at both ends. I made up a 5+ foot of PVC drain pipe for soaking ribs and fill it with hot tap water and soak over night . Refresh in the morning with hot tap and put on the kettle to boil ...then have a couple of smaller towels handy and pour some boiling water over the hot rib, wrap with the towels and soak with boiling water. ..let sit a few minutes and flex check and resoak the towels if necessary....you will have a rib like linguini and ready to set on the hull and clamp. You WILL have made sure to place the rib correctly with regard to the tapers if they are there, right ? Or, as the song goes, " baby, what a big
surprise ". This works fast and is a very handy process for a few ribs to replace. Have fun !
