Hey Matt, this is incredibly helpful - thanks for sharing! At this point in your process, it appears you're setting rail rocker? How do you go about deciding where to place the concaves/vees from here?
Matt, thanks for sharing, but i got a question, base on your knolege what is the Best minimun and maximun tail rocker a board can have, don't know if the question is right or if You get the idea of it.😅
Tough question because it depends on the length of board butlers say shortboard under 6'8" long. 1.75" to 3" have been successfully used by various shapers but let's say that I could only pick one tail rocker number for every board under 6'6", it would be 2.25"
Thanks for the videos. With the whole sag debate, wouldn’t it be worth having the board on all four points of contact since that’s how it will sit when it’s glasses?
Thank you very much for sharing your knowledge. Gone on my 7th self made board and still in search to verify where the zero rocker point should be placed and for what effect. A general indication would be much appreciated.....
TheMonkini. That is a common question even among professional shapers. I use exact center because it is fast, easy and repeatable board to board. Some will use the natural balance point of the board itself but those numbers change if the board has wax, deck pad or dings that throw the weight forward or back. All that matters is that you can take a set of numbers that you can understand and apply to a blank consistently. An extreme example would be of you made your tail the zero starting point and started your straight edge from there.
The more I learn, the more questions come to mind (so please bare with me)........please help me.... I noticed in another video you suggested a tool specific for rails called a fred-tool or something...which should a newbie use, planer or fred-tool, or sureform? Sometimes 'm seeing shapers pencil in a line down the rough rocker before shaping it...man I'm confused... Also, what if you want to shape a blank's natural rocker flatter in the entry or nose area?? Is it possible? Would I plane or skin off only the bottom of the blank starting near the center of the board blank toward nose to achieve this? And if it is too flat after doing so, would I plane or skin off something from the top deck to get the upward curve in the nose back? How do I keep the deck and bottom symmetrical from stringer out to rails (for entire length of the board)? Which comes first...the finished shaped board or the measurements, or a combo of both starting before the blank is ever touched?? help me Ole Ben Kenobi, you're my only hope!....
The Fred tool helps get a consistent bottom tuck angle, same can be done with a surform. The question of how to lower the entry rocker is a difficult one because you can't actually lower that entry rocker by planing the front, that only flattens the rocker. The easiest way to lower the entry rocker is to start your shape further back on the blank. Cutting 2 inched off the nose works wonders for lower rocker noses.
Hey Mat! Thanks for all the sharings. I'm a bit confuse because in an other video you're saying that the bar sag the blank and actually after measuring it it was the case. And now in this video you're saying the opposite. Not searching any fault in what you're saying, I'm just getting lost. Maybe here it's not the case and you eliminate the argument just because of the sickness of this particular blank wich is not sagging under the weight of the bar. Thanks a lot!
I am sorry for the confusion. The blank does deflect under it's own weight and under the weight of the rocker bar. The other video I am discussing the level of the blank and how that really does not affect the rocker measurement, just to show that you don't have to be careful about having level racks/level blank etc. The blank sag is still an issue to watch out for.
@@kazumasurfboards Thanks for the precision Matt. I've seen Leo Paul Etienne riding your boards in Guadeloupe, they were looking really great for the waves there. Keep on posting videos please, sharing is saving this profession. In my opinion this is super helpful for surf culture, thanks a lot.
love your videos, I'm keen to give shaping a go.

great stuff love your vids
Thank you

Much appreciated! been thinking about this for a log time.

I was thinking to make a ply template from an existing board with a dodge block , as in carpentry, then adjust to get ride of concaves etc ....

Olivier it does not sag
Hell I use a heavy level and get the same measurements.
