drawing on auto cad

At the last time in my class, i have been drawing some parts on auto cad, they were center board and rudder, at the beginning, i had times to measure dimensions of them.

by the way, chris sad that that parts you didn't measure it can be guessed by me, it is work.

thus, i had to submit it to chris after i printed it, i was missing some mistakes of the putting radious and names on each parts.

this picture is which i sketched

 

this picture is which i have to fix in the next time

temporary frames and lines plan

few things about what we gonna do in the next time in the class

Lines plan, i have done a little bit about this.

it is almost same with what i have done before on the card board

i have drawn lines on this, when i do this, and i used battens and ducks to draw lines here

i use ducks to hold battens when i draw curves on this, but it is important that i have to check if the line is fair or not

, when doing this, i checked many times. when it is not fair, i must doubt the point which i did, because of it must have correct line and fair when it is put on correct points

by auto cad

I drew Tool box and oil stone box by auto cad in class

actually picture 1 and 2 about blue print of the tool box and oil stone is same picture, I seperated it, and the right side picture3 is which i described the tool box as 3dimension. 

the rectangular shape with two diagonal lines in the picture in the middle side have a role when making a tool box as both sides in it, which means i have to cut the two lines and make the shape in the right side of the rectangular shape

when making the shape in the last picture, i translated the distances in picture 1, 2 into it as it is, and to keep parallel from sides to opposit sides, i need to keep fixed angle when i draw it, i did 30 degrees

these 3pictures are drawn by me.

yesterday i learned how to make the camber, there are few ways to make it,

i know one way only, i made this camber by that way

I used trim to cut half of the circle and divided the half-circle as 8pieces by using command "divide" it help to divide it as equal parts.

the horizontal line also need to divide as 4pieces and each points has lines to intersect with the lines starting from the 3points of the circle, i have to make every lines intersected then mark 3points to draw the curved line by using command "spline"

it would be used like this

i made this by auto cad which i did also in the card board 

in this way, i can do this easier than doing by hand

i have to make perpendicular with buttock 50, and measure the angle between them by angular.

and fix the angle to be 90 degrees by rotate. then it can be drawn.

lofting - 1

Lofting schedule is a plan to be sure for lofting which i have to follow.

The order is important when i draw on the card board. it goes like this sheer, deck line, chine for P, C body, stem line

chine for HB.

at the first time, i did this without the order ^^, so i had to do it again.

This is the Table of offset which say each points where the every lines have to pass

Doing lofting... this has been failed for making fair, so i fixed this again,, not enough, but better than before

this picture is when i erased my Buttock 50, 200 and 400 

Photo0529

this picture is when i erased my WL 60, 100 and 200

For i made this mistake, i should spend much time drawing lines.

----------------------------------------------------------------------------------------------------

There were many problems, actually i didn't care about stem face, fair and kinky point

originally the lines have to be curved from the chine which has the same distance in P and HB from stations

for example if the chine meets buttock 50 in P and has the distance, it must have the same distance in HB.

But, thanks to number of the mistakes i could be better on it.

A thing which i have to be careful is that i need to check the distance from FP to the C body by SFD(stem face detail)

my one was bad because it didn't fit a little bit at each points.

------------------------------------------------------------------------------------------------

The body plan should be done with gathering the information from P and H, and angled transom would be drawn with 10 degrees

tool box

Making the tool box, i made a mistake on the handle that makes loose between the handle and the top of the tool box. When i chiseled on that spot, it has been broken too much areas than what i wanted on it, probably i should do chiseling on it little by little in the point of the end,

oilstone box

making oilstonebox

I am making the oilstonebox after the toolbox, there would be some problems with it, like measuring the deep of the oilstonebox incorrectly and its inside which would be put the oilstone, has to be flat with chiseling, that is difficult, i spended a lot of time for it. Maybe, i have to keep in mind that measuring dimension is important, to make a work easy.
