'07 YAMAHA YZR-M1 V.ROSSI

MODEL CHARACTERISTICS: YAMAHA YZR-M1 2006 CAMEL TEAM. I AM BUILDING THIS VERSION OF M1 BIKE FROM THE 2005 TAMIYA KIT. AS YOU CAN SEE ON PICTURES THE COWLING IS HAND MODIFIED NOT A S27 UPGRADE. I AM DOING THE EARLY BIKE WHIT THE REAR COWL LIKE AN ARROW SHAPE, THATS BECAUSE I AM ALSO BUILDING DE 2007 BIKE JUST DONT HAVE SOME ENGINE PHOTOS TO MAKE THE COPY. I ALSO MADE MY OWN DECALS, AND BUILD IN MY LABORATORY SOME METAL PARTS. NOT WHITE METAL!!! I MADE CHROME NIQUEL PARTS LIKE BRAKE CALIPERS, REAR BRAKE TANK AND OTHER PARTS.
this photo show the front cowling being preparated to reform the wind shield.
covered with hard silicone to copy the shape.
this is the silicone i use.
this are the separated parts and the silicone pattern.
here i made a mark to the silicone mold to know the limit of the 2006/2007 model.
the blue material is dental acrylic.
the parts of the mold, ready to be finished.
now the mold to make the vacumm formed wing shields.
the mold ready.
the molds to be vacum forme in the vacum machine.
parts ready to be cutted.
the rear brake piston fixed on the frame must be modified. The reservoir tank for brake fluid must be included into the piston.
here is the original part from tamiya kit that represents the reservoir tank.
the tank is separated.
now i copy with the same silicone before used.
here is the modified parts. Copied, and maked in acrilic, styrene, and same parts from tamiya kit to get the parte needed.
close view of the right part.
to get a stronger piece to be copied and reproduced, I cast this plastic parts into Chrome Niquel alloy. In this photo you can see the silicone base and the parts atached, ready to be filled whit a refractary material.
here the refractary material fills the mold whit the parts inside, and after it become hard and burn into an electric oven at 900C, the acrylic, styerne, wax and all burnable materials completely calcinate. And only have to fill the empty spasy whit the metal at 1300C.
After remove the burned refractary material and sanded with aluminium oxyde this is the result.
here the metal parts. Now, rest to cut, correct and polish to get the final parts to be copied or used.
