Ferrari forming almost complete
I headed to class early to continue on from last week as it's much easier when 20 other people aren't there. It seems that some people spend all day in there which is not possible for my circumstances. None the less, I worked for half an hour then one guy closed the lab for some reason (I presumed he probably wanted lunch) until 1:30. In that half an hour I basically achieved the shape that I wanted with my three metal pieces.
- This session I really focussed on work hardening the pieces further and getting the minute stresses in place to hold the final shape. This was done through a high series of passes with a low pressure applied. I really didn't want to undo my previous hard work but at the same time there wasn't too much to actually do. As you can see in the photos, I managed to achieve the slight variation in angle for the centre piece as it was slightly raised. For the windscreen, the shape needed the most work from week eleven. I decided to get the fold along the centre perfect before folding the edges. This is not just a roll of the edges, it's more of a staggered taper true to the desired structure, and also providing additional strength. Also evident is the upward curve for both the top and bottom parts, working in different planes with conflicting stresses, shown in the sketch below.
- Just on working on the windscreen, as the edges were turned over a bulge began to form at the corner of the centre crease which then needed to be flattened out again. At this stage, I had to leave as the workshop was closed but I was pretty happy with how the work pieces had turned out overall.
- I managed to take a couple of files (flat and round) and sandpaper into the 24 hour space to file and smooth out the rough edges and sharp corners. It was surprising to see that the places where I trimmed with the tin snips had seemingly micro sized metal shards sticking out which was extremely hazardous. Using the rough file I got rid of these and then using a less coarse file put a slight round on the edges so they could be handled safely. Daniel told me that we weren't in fact handing in these work pieces to be marked, that it again was an online submission, so this might not have been completely necessary, however is something I've always done out of good habit, and also to make carrying the metal home easier. The sandpaper was used for finishing off the work piece.
- As you can see from the above photo, the edges were slightly rough and uneven. However the metal had a real shine and gleam to it which was nice to see. Other groups were sanding the entire surface which in my opinion ruined the metal, giving it an almost frosted look. Not only should the surface not needed to be sanded (in my opinion) as it should be completely smooth, the end result looked rough, with large pitted areas, drawing attention to the imperfections.
- Only one of my group mates was there during the lesson working on his bonnet piece as you can see. I'm really happy especially with the joints, to get such a close fit together was a big accomplishment for me and was the result of accurate measurement and trial and error (mostly the latter). My group mates work was fairly rough but you can get the idea of how it fits together, it's quite hard when the group have other major assignments to do and you're the only one there every lesson.
- Once laying the windscreen over the waffle frame, I realised there was the slightest of recesses where the glass would sit, so I amended this with the nylon mallet and the sand bag.
Working towards next lesson and the hand in: I decided to take the work home to reduce the risk of it getting stolen/damaged and to polish the metal to really pop. Next class we will take a photo of the finished product, a half complete Ferrari (due to our small group). Whilst finished structurally, I have a small idea to really make the work piece complete. Stay tuned regarding this.
