Green laser in Berlin
There's a seriously cool green laser on top of a Siemens building in Adlershof in Berlin.
MDF plug pictures
The first half of our Pikanto plug is now milled. The other half will be done next weekend - and then we have a lot of painting and sanding to do before laminating moulds.

Milling MDF
More plug milling
The model yacht plug we're making is milled in three stages. First a rough-cut, then a finish-cut which cuts the plug 1 mm undersize. Then it's coated with a thick layer of tooling gelcoat. What you see above is the final milling pass where the gelcoat is cut down to the final shape. This way we're hoping the final plug will require a minimum of painting/sanding before use.
Lester Gilbert has some new Pikanto pictures on his site. Eventually this project will produce boats like that, but with a deck which is simpler to mould, and with a process we hope to streamline as much as possible.
