Post 10. Final evaluation

To finish my mechanical toy I still had to paint it. I used acrylic paint, but the colour wasn't bright enough so I painted two or even three layers everywhere. I painted the followers but not the ends, so they could touch the cams and work properly, I also did my top part, I think I got some paint into my holes for followers, because when I tried to play with it, the followers did go through the holes, but they weren't loose and therefore my mechanism didn't work properly. So, I need to go to the workshop on the lunchtime on Monday and drill the holes one more time, in order to make extra space in holes and make the followers to up and down without any friction.

I also recorded all the steps of painting my mechanical toy:)

Today we had last lesson in workshop and we were supposed to finish or mechanical toys. 

So today I finished making my ship, I sanded the edges, glued it on top of the follower and got all the cams fixed. 

So, I had my mechanical toy pretty much finished and I had to just test it and see what's goes right and what goes wrong and fix it. When I tested it, I realized that my front waves go up and down as they were supposed to, but they also span around. So I had to drill small holes at the end of the waves and the holes that are parallel to the ones in the waves. Then we putted pieces of wire in those holes, so they would kind of support the waves and stop them from turning. 

 My cams would hardly work because it moved the top part, so I had to make it stay still. Mr Andrews showed us how to do it, we just had to drill the holes through both of the tops and into the side of the box and then put the wire in that hole. But I thought it would be easier if I did the same thing but on the sides of the box, so it went through the side wall and into the pieces of wood that are joined with the top. When I did so, it worked out really well, it's now working properly. So, at the end of this lesson i had my toy finished and ready to be played with. I also took couple of pictures of my mechanical toy. 

So now, I will paint it on the weekends and bring it back on Monday for Mr Andrews to get it assessed.

On today's lesson I made all the round cams. The only problem I had was using mini- band saw. It was a bit harder than I thought it would be. But fortunately for me I had to cut just one cam out. My cam wasn't really accurate so I had to sand it down. When I've done it, I got the cam still not perfect one, but good enough to make my mechanism work. 

I've also finished my box, so now I'm going to make my design which is on top of the box. Next lesson I will need to make 3 small waves that are not moving and are situated at the front and 2 big waves that are going to move and which are situated in the middle as the have to be held on the axis. Next lesson I will also need to make a sail boat. Everything will be made from the timber, except for the sail, I'll make it from the cupboard. 

That's what I had at the beginning of the lesson. 

This picture  shows what I got at the end of this lesson.

Today we went to the workshop on the lunchtime with Mr Andrews, as we are running out of time and we won't be able to finish our mechanical toys. Jill and I were late because we were doing her history speech. But on today's session I've fixed 2 out of 3 cams and next lesson I will just need to finish the last cam and check that everything is working.

On today's lesson a lot of people were absent because of the softball. Everyone got a lot of work done. On today's lesson i finally learned how to set up a drill with round nozzle to make circular cams and I'm not freaking out now when using the drill, which is a big step up for me. Today we were talking that we might not get our work done before the end of term, so I've changed my design a bit, so it will take me less time to finish. I've decided that I'm going to make just one ship instead of two and I'll have just two waves moving, instead of three. I got 2 cams done, I had time to make just one hole and so I have just one offset cam now. So next lesson I will need to make last cam to be offset cam. I will also need to make a pear shaped cam for the ship. 

For our homework tonight we have to do 1:1 drawing of all the cams that we are using, how they are working and where they are situated in the box. 

So today's lesson was really productive for me, I need to work hard, because we have just 6 lessons left and a lot of work to be done.

On today's lesson we were down in workshop. I made a hole for the small circle that goes on the end of an centre axis. Mr Andrews said that my sides are moving, this means that I used not enough glue, so I took both sides off and redone it with a right amount of glue. I also used this thing that helps you check the right angle of the things. The only problem that I had was the extra glue on the surface of the timber. I had to take it of as the side edge wouldn't fit in there. I also got rid of the extra timber that was supporting the sides, I also sand it down. We also got a lot of homework for tonight. Apart for the Blogg, we have to do a list of cams that we use, their 1:1 drawing and errors showing where  they are situated in the actual box. 

So next lesson I'm going to start making cams.

On today's lesson I did a pretty good job, it was a productive lesson for me. I finished the box for my mechanical toy. So the biggest problem for me was to cut the circles using the drill as it is kind of dangerous and I was scared at the first time, but then when I've started using it, I realized that it's not that hard and scary actually. Another problem that I had was probably putting this center-stick into the bigger circle and glue it. because it was a really good glue that sticks two parts together in couple of seconds, so I had to do it quickly. And to my surprise the stick got stuck in the circle and didn't want to go all the way through it, so I've used a hammer to give it some more pressure and it went too far away, like to the middle, so i had to pull it up again. It was hard, but funny. But I finally got it right, I think I've solved the problem really quickly and in a fun way.
I've also done the small circle for another side of the stick, but I still need to make a hole of a right size. So next lesson I will finish doing that, and then I'll start making the cams, I will need two offset cams for the ships and three for the waves. That's my plan for the next lesson. But if I'll finish doing that, which is unlikely to happen, but if I do, I will start cutting the design of my top part of the toy.
That's my box and the small circle that I am going to finish next lesson.
