Ich garantiere bei meinen Bauberichten und Teilelisten keine Vollständigkeit etc...es wird aus den Teilen gebastelt die gerade herumliegen.
Bitte keine Anfragen zum Bau/Fräsen von Frames, Teilen oder sonstigen Aufträgen. Ich betreibe die Seite rein als Hobby und nutze die zur Verfügung stehende Zeit gerne für meine eigenen Projekte.
Bei einigen Projekten werde ich zu gegebener Zeit die Pläne veröffentlichen - aber auch hier lasse ich mich ungern hetzten ;-)

No waranties for completeness of any contructions, part lists etc.. I build from party i have just lying around in my workshop.
Please, No requests to buy frames, builds, etc.. I run this page in my spare-time and as hobby only. Want to keep my free time to work on my own projects - sorry
I will release the plans for some build at some point in time, but again, please don't ask for unreleased plans, i don't want to get rushed ;-)
