PART 8: IN WHICH I TIE UP A FEW LOOSE ENDS, HAVE ONE MORE SUCCESS AND ONE MORE FAILURE
I think this post will pretty much conclude this series. Happy to keep commenting, of course, and if anything dramatic happens down the track, I'll add a bit, but for now, my self-inflicted crash course in casting is coming to an end. From here on, I'm using the skills I'm learning to actually make working customs (of which the red Rumble gun is an example).
First up is an addition to the Plastimake (thermoplastic), even though I did discover that its applications are limited (I did use some to fix my clothes airer at home though - winning!). Even though I'm using an unofficial/no-name version of the Plastimake product, I went on the Plastimake website and ordered some colouring pellets. A 4 pack of yellow, red, blue and black set me back about $15 from memory.
It works by dropping a few pellets (which are about 1-2mm square each) per tablespoon or so of Plastimake pellets and mixing it through while it is soft. Even though the bags are pretty small, it will clearly go a very long way. I started mixing the straight colours and then tried mixing colours together. The results were pretty good, with the exception of the purple and brown, which just look ugly. You can lighten colours by adding extra regular (white) Plastimake to a pre-coloured piece of Plastimake.
This might come in handy if I want to make pegs and such of a particular colour that I don't want to paint lest I get paint wear.
Back to the failed 2 piece mould from the last instalment, the handle section of Scoops Targetmaster. As I had to pour resin into the two halves of the stuck together mould and then jam it together quickly, I was kind of expecting a mess, but it came out close to perfect.
There was a small flaw on the other side (not photographed), but easily fixed.
Another product at Barnes was a pigment for the resin. Like the Plastimake colour pellets, a very little goes a very long way, so even though the small jar was $10 or so, as long as it doesn't dry out, it will probably last me until the grave.
I used the same mould as the pic above, but just focusing on the handle/peg. Came out stellar, the details are translated perfectly.
Since abject failure has been a running theme of this thread (it's like watching Bathurst - barely anyone would be interested if it wasn't for the promise of the odd wreck during the race), I wanted to post up an example of an epic fail of a Pinkysil/Easycast resin attempt. It was meant to be the rear legs and alligator head from a TR Skullsmasher that I was doing as a mock up for another custom, that I will be creating a WIP thread for shortly.
Here's the Pinkysil moulds:
The problem (I think!) was that I failed to mix the resin adequately, or not an exact enough ratio of the 2 parts. The legs disintegrated into a sticky mess, The head came out mostly formed, but the end of the snout was soft and bendy and sticky to the tough. It never hardened. Not good for anything but scrap. Same goes for the moulds, as they still have some of the sticky stuff in them and I don't know how a new batch of resin will react to the material already stuck in the bottom of the mould, and I don't want to waste more resin trying to find out.
If you've been a follower of this thread and have made it through to the end, thanks for sticking around for the fun! I have to say, it's been a blast. If you have a thought to try it out yourself, I say go for it. If my attempts have shown anything at all, its that failure is OK, and that without it, you'll never get to the good stuff. The journey is worth it.
