Update | frame and tank welding

The last 2 weekends I have been at WiMoto, the workshop of Wido Veldman. He is an awesome skilled welder who has been helping me with the subframe of my cafe racer. The steel tank has been made of sheet metal, clean TIG-wedling!
The body and tank will be mounted on the frame with slim tank mounting rubbers; to eliminate all possible vibration problems!

Update | fitting tank cap and rear light

The body has been trimmed; the rough glass fiber edges have been trimmed off. Even so the cuts have been made to fit in the fuel cap and the rear light. Using a lot of paper templates made in Solidworks; digital CAD modelling.
The body and the frame will be joined soon! Some brackets and flanges will be welded on the frame to bolt the body on the frame.

Update | Handmade glass fiber body

Last weeks I have been working on the handmade glass fiber body for the MTD café racer. With the valuable help of Antony, one of my Spark design & innovation colleagues! Check our website http://www.sparkdesign.nl/

After two layers of white gel coat, the glass fibers have been positioned in the mold and soaked in epoxy resin. Lot of small clamps kept the fibers in place while adding the peel-ply and all the foils and vacuum plastics layers.

After the epoxy resin hardened the mold was opened and made super happy! The body is super clean and fitting on the frame perfectly! The coming period the body will be sanded and painted. Keep posted for the latest developments.

Update | Mold making

The three molds for the MTD café racer are finished! The glass fiber molds have been made following the hand lay-up glass fiber laminating. Over the HD PU plugs; which are the CNC milled positive parts of the final motorcycle body.

The plugs have been sanded super smoothly and finished with a clear coat. On top of this coat 7 layers of mold release wax have been added.

All the layers and patterns for all the glass fiber fabrics have been cut with care, and fitted on the plugs before adding the polyester resin. After which the laminating started, merging the fibers with the resin over the plugs.

After the polyester completely hardened the rough edges of the molds have been trimmed, releasing wedges were slammed between the molds and the plugs,… and finally air pressure and two large chisels released the molds from the plugs!

Now these molds will be bolted together for construct the large mold in which the body kit will be made. Keep in touch for more footage..

The first body kit of the custom MTD Ducati café racer will soon be made. If you have interest in this body kit send an email to info@maartentimmer.com

Update | Sanding the plugs for mold making

The last two weeks I have been sanding the HD PU plugs. These parts need to be super smooth before I send those over for a coat of 2K-paint. 2 coats of spray filler have been added and many hours of sanding.
Looking for the right company for the paint job now..
