if you have been following my efforts with producing Molds and Rubber components for the Bellett's, you would know I have managed to produce Timing Chain Tensioner, Steering Rack isolators and Sway Bar rubbers.
to date I have not fitted a Chain Tensioner inside a running engine, so I do want to test that before selling them.
Steering rack and Sway Bar rubbers have been fitted and are working very well.

but I have been wanting to produce a more difficult, 3 or 4 piece mold and pour a successful rubber component.
as I won a brand new rear brake cylinder on eBay and it included the rear external handbrake seal, I decided to give that a go.

the mold process was not too difficult, but every pour I did was incomplete with the rubber missing at both ends.

but I continued trying different ways of preparing and pouring and tonight I opened my first successful component.
Wahoo!!!
that was particularly rewarding as it can be even more difficult to produce a good part in colder weather as temperature has a significant part to play in failure or success of the pour.

just one more part that I can now reproduce and not have to worry about running out.

below are a few photos. the good pour is still on the base mold and one of the failed ones sitting beside it.

For a second I thought you were making you own kidneys for transplant......
Then I actually read the post and had a big sigh of relief ;)

Your patience has been rewarded Oz

Excellent effort there Oz :P
I was watching American Restoration the other night and saw them remaking an indicator
Lens for an old Czech motor scooter using a silicone mould of the other good one like your
method. What I want to know is what pourable resin would they have used and where could
we get some to start making our own Bellett lenses... Even the front glass ones..... Or maybe
thicker plastic badges than the ones I engrave.

Badges would not be a problem Lewis as the badges ray had made for the club would be a good example. I will chat about this with Isuzu sports and see what they do for them next week :?: maybe we can get some made :!:

am actually looking at resin pours as I have been given a hard resin mold for the round GT front indicator lens.
would look at doing sedan brake and indicator lenses and even front guard and bumper lenses.
my molds would be created from firm but soft rubber, and rear sedan lights would use quite a bit of mold material and resin mix.
the resin material is clear, so I can add orange or red colouring. a small amount of white could make the front indicators look smoky and not quite clear.

Resin pours require only 4 hours to harden but need to be secondary hardened and at approx. 100 degrees C

I will keep updating as I try more stuff out.

Hey Oz, great work on the rubber seal above!

It's been awhile so wondering if there is any update on other parts? Lenses etc?

Following with interest :)

GREAT WORK OZ!!
Have you worked out how to do the engine mounts?
Hm, not easy I hear?

Not at all, Dave. Would need to invest in an Industrial Oven and it would take quite a lot of $80 engine mounts to recoup the cost.
Happy to say our local guy who is supplying at the moment, is doing great job, and i will continue to use his service.
