All up I estimate this will take 1.5-2 weeks working 9-5. There is quite a lot to do, but I have nearly all of the parts already or on order so there shouldn't I waiting for anything. Also my new lathe has speeded up lathing quite a bit. My last exam is on the 24th of june, so after then I am planing on working pretty much continuously. Hopefully we will be ready to conduct a test in the third week of the holidays. I would also like to use some of my holiday time to another project, which I wont discuss now.
As for the test site, its still not clear where we are going to conduct the test. There is talk of using a location at pinjara hills, but its not certain yet. I have a few friends who have farms etc which we could use but they will be at least a two hour drive.
