Printing is on!

My ultimaker is on an endurance test, it is running for 16h nonstop.
I was waiting for quite some time for the printer, so i had plenty of things to print.

this are two hlafs of a rudder

it is basically the same as the one on fila, two or three thick layers of 2k paint will be needed to cover the steps from printing

this print will be used as a rudder on fila, the next print will serve as a positive for moulds

For future F5g boats such as evolution, cardio etc. a new bulb will be introduced

this is the printed positive, painting is required before a mould can be made, it took the printer 4h to print this

the expected weight is 700g, it is 22cm long and has a max thickness of 12% at 40% of chord

this is the first sold print, it is a gimbal mounting plate, for my friends hexacopter

The last print for today is a keychain for my girlfriend, after that the printer will get a well deserved rest. :)

IMO the prices are fair, much cheaper than other guys..  

IOM bits arrived

A month ago i ordered some IOM bits from chrissails.
These are a Dave Creed build keel fin, rudder, mast-finn box and a plain bulb.

Everything was nicely packed and arrived undamaged.
details:

The bulb needs to be sanded, filled and painted, mounting holes have to be drilled.
There seems to be a stainless steel rod through the midle of the casting to prevent bending, it also gives a sharp end to the bulb, Clever :)

The keel's core is foam, in the middle there is a fullcarbon strtut approx. 12x4 mm giving the strenght, the skin seem sto be two layers of carbon on each side, 4 in total.
Thicknes is about 7% of the chord

The rudder is stiff, there are some moulding faults in the lower part, but not a big deal, i dont realy like the shape, because the lover edge, which is a v, does not align with the waterline if the strut is positioned vertically.

Mast-fin box is stiff, weighs 28g

I am happy with the investment, these parts will go into my first IOM boat.
And will be definately used as a reference when designing my own foils.
