AoS28: Freyvid Hafnar - The Eclipse

Is it like the hand of God hovering above?

Freyvid Hafnar, Chief investigator of the Barak-Nar Biologis Guild, had been commissioned, alongside an Overlord warfleet, to venture into the humid cloudbanks of Ghyran in search of a missing explorator fleet. The Kharadron had long forsaken the realm of life for the riches of their native Chamon, but greed and hubris garnered from their dominion over the skies eventually pushed them outward. Rumors circulated the airways of some daemonic taint that had begun to overtake some of the farther reaches of the realm, and the Admiral Counsel began to fear that their ships may have been lost to its vile clutches. In hopes of salvaging something from the lost venture, they commissioned a Grundcorps reconnaissance fleet to investigate, with Hafnar amongst their storied crew. Never ones for superstition, the Barak-Nar Admirals reasoned that a scientist would prove useful in case the lost fleet met their end via some unconventional means. Hafnar was also somewhat of an expert on Nurgle pox and maladies, if anyone could truly be called such, studying the Guild’s labyrinthine archives on the matter. Whatever the fate of the lost ships, the decaying hand of Nurgle or otherwise, they would be found and avenged…

Dragged into Turbolasers Episode 22: A classic design revisited, Primaris Space Marines

Hope is a mistake.

With this episode we are joined by the extraordinarily talented Mr_Pink, from the blog Modern Synthesist, to talk about the newly revealed Primaris Space Marines. We talk at length about the models as well as the lore surrounding them.

Ways to improve resin casting: pressure and vacuum chambers

Using a pressure chamber dramatically improved my resin casting.

Getting into resin casting can be a difficult thing, with so many details to consider (what silcone and resin to use, how to create effective vents, etc.), that it is easy to get overwhelmed. I found one of the trickiest elements was determining how pressure and vacuum chambers can be used to improve the process. Both are used to reduce bubbles in the final product, but since they work in very different ways, each is suitable for a different aspect of the process. A vacuum chamber is used to physically remove bubbles from a material (and all the air from the chamber itself) by creating a vacuum, while a pressure chamber shrinks any bubbles present in the material via pressure. Because the mixing process of silicone introduces air bubbles into it, a vacuum is applied to the mixture before using it (pouring it) to create a mold. This is possible due to the slow curing time of most silicone (~5 hrs). Resin, however, solidifies much more quickly (~15 min.), making a vacuum not a viable way for removing the bubbles in resin before injecting it into the mold. Instead, the mold is placed in a pressure chamber after the resin is added, to shrink any bubble to a negligible size. Although using both strategies are not absolutely necessary for creating molds and using them for casting, from experience, it dramatically improves the final product. I currently use both, and they allowed me to nicely cast the true-scale Space Marine that I recently built. In this post, I wanted to talk about both vacuum chambers and pressure chambers, and how they were important for dramatically improving my resin casting abilities.
