Queadlunn- I’ve tried a couple new methods for my polycarbonate gem faceting. I cut another gem (the shape turned out a lot better this time too!) and this time I used iDye Poly to color it.
-WALL OF TEXT INCOMING-
The method of how I made the gem out of poly is pretty much the same as the last one (LINK), I had a cylindrical piece about 1x3” in size and I ground it into a (base) 3-sided pattern that worked pretty nicely. The disk sander we have currently has 80-grit on it, from there I moved to 220-grit, then 400-grit, then a felt polishing wheel (just sitting on my desk), then burnishing with cloth. This got me to image #4 which was looking really nice.
Since my last attempt to dye poly with standard fabric dye was a failure, I used some synthetic-compatible dye that Cata had bought me (iDye Poly, see image #5). I got the dye ready on the stove and dipped the gem in it for about 3 minutes total in 2 runs. I was really careful with the temperature this time (might have been around 85c or 90c or so) since the first test gem ended up with tiny thermal fractures on many facets. After the dye bath I was at image #1.
One drawback with the dyebath is that while it does seem to penetrate, it’s less than 0.2mm (with solid plastic this is understandable) and the dye process does take a bit of the luster from the earlier polishing off and it’s not something you can get back with polishing since you’ll just wear through the dyed plastic.
Since the gem wasn’t quite as shiny as I wanted now, I added a thin coat of Future to bring it back to a nice shine (image #1). Worked pretty well but I’ll need to airbrush the future on next time.
Overall, I think this is a great process, given that you have access to a bench disk sander and access to larger pieces of polycarbonate.
I’ve got one more of these planned, a larger one. I’m thinking of taking video of the faceting process but I’m still figuring that, and the material, out. Also thinking of trying a long-term soak dye (cold) to see if that gets the color farther in the plastic so I can re-polish without having to topcoat the gems.
The well used PSPmetalart Wheel Polishing Machine, along with a couple of fully polished 2010 Dodge SRT wheels. The wheel polishing machine is brutal to operate, but it is an indispensable tool for custom polishing aluminum alloy wheels.
There are only a handful of these machines left in the world…
‘An Unexpected Friendship’ - a short comics I made for ‘Zeszyty Komiksowe’ nr 20 (You can read my article ‘Dojin in Poland’ in this issue). The whole of this comics wasn’t published, so you can see it now ;)
(Yeah, I know the older girl looks like Laura from WicDiv - it was unitentional but probably my deep love for Laura’s design took a wheel.)
When the Sunoco Ferrari 512 M first appeared at Daytona in 1971 it was a revelation. Manned by a dream team that included owner Roger Penske, chief mechanic John “Woody” Woodard, and drivers Mark Donohue and David Hobbs, the car combined Ferrari’s pedigree with Penske’s legendary attention to detail in everything from his crew’s uniforms to the polished wheels. Slated to run at Daytona, Sebring, Le Mans, and Watkins Glen, this 512 M was the odds-on favorite every time the Penske team rolled it onto the starting grid.
