Shiny Formers




















Key
Finished and filled, there's something every model maker needs to learn and that's when to stop, being too particular will take for ever. The key has been given several layers of clear cellulose lacquer in a slight speckle. After 2 days to cure this will be polished back to give a good surface to mould from. The area's that are hard to polish will remain textured from the spray, mimicking the randomness of the stamped metal effect.

Fact -I discovered that to give a beaten affect to an object, brush and stipple wax into the mould. This is what was done on Gladiator so a single mould could be used to produce many helmet with different variations of damage....

LED
First post for the LED, turned on the lathe from chemi-wood, to an amazing finish then lacquered same as the key, and after a few days will be polished using T-cut to make a glass like surface. (also a few layers of Mirror Wax will maker the surface better and easier to de mould)

Contacted Mould life and Alchemy,

Alchemy's advice.
-3660 clear urethane slow, would be best for my LED casting with TRIA inks for the colour, costing £33.15 for the kilo kit. But still need to research the mould required, some urethane reactions are inhibited by tin cure silicones. May need a platinum silicone.

Mould Life advice
-Optic clear 31, mould life are particularly reliable when it comes to advice, and I have used their poly optics before. Will cost around £42 for the smallest kit and will require a Tinsel 40 mould costing around £30. Using TRIA inks for the colour.

ATM - cost is the main concern.....so it hangs on the 3660 mould requirements. TRIA inks cost around £5 a colour.....

CASTING ADVICE
-When using TRIA red ink into clear urethanes, always make it darker than you want when mixing, they lighten up when they curing
-Using standard urethane pigments with 3660 make it loose its transparency.

Weaving
In the image above I tested making a new weaving needle, meaning I could weave 3 stitches at the same time. This did not work, so back to one at a time.

-Note added new link to the giant magnetic letter I will be making.....
