Re: Thundercats Sword of Omens build (6-1 update w. images pg.9)
For those who have been asking, There WILL be a run once i get some test castings done and working smoothly
Thanks everyone for their insane level of patience with this project!
Time to Mold!
In order to save myself from having to clay up the whole thing, I cut a hole into some hardboard, and raised it up with insulation foam. When claying, I also included a ton of keys and a thin channel that will make sure the edges remain aligned.
Print coat! (Smooth-on rebound 25). The excess was poured into clay scraps to make nubs
a few coats of rebound later, and added the nubs to help lock it into the mother mold (this should help prevent potential "sagging" while casting). I had some sonite wax laying around, so i coated the hardboard with it, to hel[p make it easier to remove when casting the second half.
Plastipaste! looks delicious! (I like to measure my stuff by weight because I personally find it faster, and get to use my shriveling math muscle a little at least!)
After smearing on the plastipaste, I added tissue to the surface and pat it smooth. Plasti-paste tends to leave tons of sharp mean edges. Less sanding to do, and its easier on the hands, especially with the weight of this thing.
When the plasti-paste set, I flipped it over and began demolding that side.
the wax worked great, and the harboard just popped right off with no trouble!
After coating the silicone and plastipaste with more sonite, the same was done for the second half. after the thin print coat, I built up the sides (where the keys are) quickly using thivex silicone thickener.. a coulpe more regular coats of silicone were added to the rest of the sword, then topped off with thicker silicone to get the pesky raised areas taken care of.
Here's the first half of the mold, ready for the second half of the mold
Plastipaste again, and once that set enough, I sanded the edges. Its sitting in the middle of the living room waiting to get demolded.
Time to do finger crossing!!
