Review - "Instant Mold" Part 2
I then left the house for the day, and on my return pulled apart the two part pattern to reveal the new green stuff cast. Although the green stuff was "sticky" it did not actually STICK to the "Instant Mold", but it was clear that the putty was not properly cured. This is probably partly to do with the fact that it doesn't get air to help it along, but also just due to the sheer bulk of the component (I'mmuch more used to working with smaller quantities for fine details.
Here is the end result of my first test. As you can see, it needs a lot of cleaning up and there are some holes that will need filling too. But whilst that was going on I threw another batch of green stuff into the pattern to cure.
Still, undeterred I set about trying a different component.
In summary, I think there is a great dealof mileage for using "Instant Mold" to create additional components. My initial experiments showed that it is a bit trickier than you might first think, but this is probably because I jumped in at the deep end to create a 2-part pattern. A simple press mould would be much easier but has limits on what can be created. Of course, there is always the option to create two (or more) separate press moulds and then glue the separate components together!
However, if this has taught me one thing... (other than I needed to buy more fresh green stuff) it is that you don't have to be limited by what you have...
