[QUOTE="Vipersan, post: 924247, member: 325666"] Not yet there but bloody close I think ... Here are some photos of my first attempt to cast a replacement cam component in liquid plastic ... If successful it would of course have to be drilled out ... As expected air bubbles trapped in the confined space of the silicon rubber mold are causing problems ... These 'bubbles' can be clearly seen in the first component made.. luckilly the part is easily removed and does not stick to the mold thus once cleaned it can be re-used if handled gently.. rgds VS Time to invest in some disposable syringes I think ... These of course could only be used once per session ...(the more molds I have on the go the better) ..but would allow sufficient 'mixed' plastic to be drawn up and injected under pressure into the mold ...and maybe less air bubbles resulting.. just an idea as yet .. we shall see... ...also adding a hole at the top of the mold and inserting a plastic drinking straw would help to allow trapped air to be forced out.
