Rib replacement pictorial

[59FLPAN]

HI AGAIN KARL, I FOUND A SOURCE THAT IS VERY CLOSE TO ME FOR THE WHITE OAK LUMBER, HE A CAN DO MOST OF THE MILLING FOR ME, HE WANTS TO KNOW WHAT SIDE OF THE RIB HAS THE QUARTER SAWN GRAIN? ANY PARTICULAR WAY TO MILL IT?

THANKS FOR YOUR TIME

Jeff. Take one of your ribs that you remove and show it to him.
I am not schooled in the milling of lumber but I believe that 1/4 sawn oak(as it's name inplies) will determine the way the grain runs. And to the best of my knowledge the grain will run thru out the board.
The boards that I used were five quarter x 8 inch boards, appx.
In other words they were 1and 1/4 inches thick by 8 inches wide. I set my saw to the desired thickness( in my case 5/8 of an inch thick) and ripped the stock like strips of bacon off a slab. Then ran the strips thru the saw again to remove the 1/8 of an inch needed to acheive a width of 1 and 5/8 inches.
If you picture looking at the end of a log as a circle when it is quarter sawn the logs are sawn the length of the log to what ever depth is needed and then the log is rotated and sawn again. Creating a board with beautiful marling(sp).
As compared to just putting a log on a mill and cutting it all the way thru lengthwise from side to side.
Hope this make sense.
Karl.

Correction Jeff.
I meant to say that the width of my rib was 1 and 1/8 inches. Not 1 and 5/8 inches. Hence the use of the five-quarter board. Spent a long hot day working on a boat that wasn't wood

1960s Cortland built boats by Thompson Boat Company of New York, Inc. have rib and keelson construction different than the boats made at Peshtigo by Thompson Bros. Boat Mfg. Co., Inc.

THANKS FOR THE INFO ANDREAS, SO WHAT WOULD BE THE BEST METHOD OF REMOVAL OF RIBS ON A CORTLAND BUILT BOAT? DO THEY ATTACH FROM INSIDE THE HULL? I THOUGHT I NOTICED SOME NAILS OR SCREWS INSIDE THE HULL SIDE OF THE RIBS, THIS METHOD IF CORRECT WILL BE MUCH EASIER TO REPLACE RIBS, ARE THE RIBS TWO PIECE, ONE FOR PORT SIDE AND ONE FOR STARBOARD SIDE?

THANKS FOR YOUR INPUT
