Go Go Go

Hi.
It's been a while and there is lots to tell. We have just had 2 weeks with no students and during that time I made a prototype to test and refine the process and check the completed product. On the whole all went to plan and there will only be small tweeks to the process that I had planned.
The prototype came out well! There was a bit of a problem with the resin building up at each edge but I was able to squeeze most of that out with a veneer 'hammer' whilst the board was in the vacuum press. In the next ones we are using less resin and a rubber squeegee to spread the glue (Phill from Polymer Engineering suggested this and a couple of other changes. Thanks Phill.) I have also added an extra insert to be used to align the core and the base during the lay up. This is machined in the core in the usual way then super glued to the base before laying up. The insert, now fixed to the base, is used to align the 2 parts during lay up to ensure that there is no exposed timber in the completed board. Which could happen if the core is misaligned. We are also using some micro bollons mixed into the resin for the egdes to help fill the voids formed by the tangs on the edges.


















This is the prototype in the press.
