Lofting(2)

It was great opportunity to lean practical terms of boat building. Although nowadays people use computers for saving time and being accurate, to draw lofting by hand helps me to understand exact process and I was able to check myself at the end.

I discovered accuracy is very important  in lofting because, if not, we cannot make fair boat from that lofting and we might spent more time and material to fix it. The reason why I had to double check was to make my lines were right. I cared the thickness of pencil and even the angel when I grip the pencil. Moreover, once we make mistake, it was pretty complicated to delete and redraw so I consumed much time.

While I was doing lofting, I found somethings was wrong. I compared my lofting and the real plan which my tutor gave and figured out that our table offsets was wrong.

I realized that if one point had been changed the others might be changed too. To check these, I use the intersection points both profile and half breath.  Here is the half breath offsets that I changed.

Starting with lofting I had learnt a lot of new terms about boat building. Through this period, I used    these terms and draw myself,so I could fully understand. Also, our class mates shared information and new terms in our own web site. It really helped me as well.

Generally, we draw half of ship because, most boat hulls are symmetrical.
First, we need to draw profile and half breath. To draw these, we use table offset. It shows exact points to loft hull lines regarding station lines, water lines and buttock lines.

 Make an inclined plane with a hand plane. Moreover gave a roundy groove to the bottom of timber with a cabinet scraper. It is pretty hard because it oftten stuck in the middle and makes bad scars. 

Completed!!

I should be careful like this guy~!!

Using 'Router' was not easy. Because the blade is spining very fast, it could bounce off anywhere if we do not hold it tight.

Opps~! I made a mistake



I turned the machine off  and I moved it, but the Router was still working and I made another mistake. Under the chisel in the picture, there was some scard.    

I decided to fix it. First, I shaved that mistake part as a squre with a chisel. Then, I found and glued a small piece of  wood which has same colour and grains as the main timber.
