Today was THE DAY, when i could try the pressing. Steps of the process were these:

pressing1

At first I was mixing a glue. As my course mate Anita said, the consistence should be as a pancake dough:) Danish, probably!

pressing2

Then came ply covering with the glue.

pressing3

Fixing ply to the mold.

pressing4

The mold was putted in a vacuum bag for pressing ply. The pressure is the bag is around 7kg/1cm2.

pressing5

The vacuum bag with the mold should be kept in oven with 50*C for 2 hours.

pressing7

After 2 hours I got this! The whole shape was quite close to expected.

pressing8

But there are some unavoidable defects. Seems that I have to do pressing once again…

I have started to do a mold. At least to prepare for that. Actually that is more complicated as I have been thinking. There should be taken in an account that plywood is changing when bent, so I had to add some extra degrees to the curve. It is quite extremely, because my precise previous work now is changed.

Endings of the bent part are quite important. So there should be double details for squeezing a plywood piece. This is quite challenging – will the system work as supposed ?
