We began to dispose of the copper pipes, which were collected from the school and were considered a waste product.It took a lot of time and effort to remove the wood outside the copper pipe with a saw, and the boys were very careful to contribute their efforts.Later, when we were assembling the copper pipes, we again encountered a very difficult problem — we could not fix the connection between the two copper pipes. We tried many methods, such as using hot melt adhesive, using high temperature heating wire welding and so on.
Because of the serious problem that we could not fix the copper pipe in the early stage, we could not proceed when we were making the copper pipe tree, which took a lot of time and affected our time. But fortunately, we finally found a suitable way to use the sol in the copper tube internal connection first paste, and then use a spray gun to melt the wire welding in the copper tube external,
so that the copper tube fixed connection. Show the final effect.
During the installation, the tutor informed us that we needed to help group 8 install the top of their design together.And to say that our two groups of design together, the news for us is sudden and beneficial.Just enough for us to hang the clouds on top of their stainless steel.
For the evening party, we prepared colorful lights and some desserts, and painted the names of the four harry potter houses on the gingerbread man.
