Kotobukiya's Nineball

    An AC's exact height(excluding ACV) has always puzzled a lot of its fans, with some speculating they're several hundred feet tall while developers Fromsoftware say they're around 10 meters. In the japanese wikipedia it is said that the ACs in the AC1 era are estimated to be around 6 meters, but it's not easy to get an exact figure due to a lot of inconsistencies in the game. Based from the number of concept art that I've been gathering over the past few years, it suggests that the AC1-era AC's should be around 7-8 meters high, close to the height of the "labors" from Patlabor.

The lesser of two evils

 With the air bubble problems I'm having with easycast, I thought using a slow setting resin shouldn't have those problems. Apparently not. After waiting for an hour to demould, not only did it have large air bubbles, it had hundreds of tiny bubbles scattered throughout the surface.

  

  So I guess I'll stay with easycast until I find something better. For now I was able to reduce the large bubble gaps by making larger air vents.

Learning the hard way

Using fast curing resin was a bad idea. The resin starts to set within seconds that by the time you start pouring, it barely has enough time to completely fill the mold, leaving gaps in the cast part. Then there's the issue of trapped air inside the mold. Adding vents helped release the trapped air to some extent but some air pockets are still unable to escape since the resin sets too fast.
