The measurements I’m using come from a set of canoe plans in “Canoecraft.” I draw the grid on a piece of paper and space the grid lines two inches apart. There are a few places you can find tables of offsets from someone who has designed the canoe. Does this answer your question?
@@David-ex8dj yes. But i have made a model and would like to obtain the measurements. I guess its a headache to obtain the measurements from the model. The model is 39 feet long and 13 feet wide
Roy, if you are trying to capture the measurements from an existing mold, or model, one of the easiest ways to do that is by using a 3D scanner. There are handheld laser scanners that can accomplish this. Then someone, from within the software you would create your slices (stations) and take measurements from within the software to create your own tables of offsets.
Very clear and simple explanation! Most designers forget that a lot of folks aren’t boat builders and are just wanting to build their own boat for whatever reason. So they buy plans and then scratch their heads for the next year trying to figure them out.
This was very helpful. I want to build the hiawatha from this same book, but I can't find the plans anywhere and couldn't get my head around how to translate the table info into useful shapes. Thank you for the great demonstration.
@@BOMBERORAFA the + is meant to be an indication of a sixteenth of an inch, approximately. Once I have all of the points plotted, accurately using rulers and t-squares, then I draw the curve. Plotting the points accurately to the sixteenth is close enough for drawing the curve. One if these days I'm going to create a file to cut the stations on a CNC machine. But, for that I think I want to account for material thickness and determine the appropriate cutting angle to blend to the next station appropriately.
Very nice sir. For those who still cant understand how this is done, just find and open in new window the tables of offsets of the freedom canoe ( https :// www.instructables.com/id/Building-A-Cedar-Strip-Canoe/ ) ,put the windows side by side and watch the video. The table of offsets may look like confusing but once you learn it its pretty easy.
*I have already built two Boats. Both were a great success and the building was very straight forward. I have recommended your plans for a long time now [Check Details Here==>**plus.google.com/102864527681244896357/posts/8Hw8CJUYT8H** ] . I look forward to building Eight Boat soon. Thanks.*
Your video has been very helpful to me. I am lofting plans out of Canoecraft for Bob's Special Chestnut Classic. If you still have this book, would you mind looking at the lofting for the stem on page 47? Waterline 20" makes no sense to me whatsoever. Additionally, this plan calls for a station 7 but the the measurements are from station 6. I'm thinking to skip station 7 altogether and just make a stem and stern station to attach perpendicularly to station 6. At this point I have ignored WL 20 and freehanded a line up to about a 3/4 of an inch below the profile of station 6, so that I have room to laminate up a stem to come up even with the top of station 6. What do you think?
Thank you for explaining the table. it's a bit clearer now. I'm not sure where you get the line for the gunwale from I think the table I have works the other way up as it has height from baseline to gunwale as the first measurement
