Why not use something like a Hitachi Magic Wand? Remove the normal "head", and drill a hole in the platform (of the correct size to fit the drive shaft off the motor) you are using to hold the mold - turn on the wand when pouring?Show Image(https://static1.squarespace.com/static/55762475e4b0c16ac86e508c/t/55b28899e4b0b85c405acd90/1437763743435/?format=750w)
Or just keep it as is, and hold it near the mold when pouring the resin?
Ha, yes. But it is not mine, the wife maintains control of it... You could go for a larger version, like one use for pouring concrete:Show Image(http://img.diytrade.com/smimg/165826/1036685-262231-0/nn/b72.jpg)
Hey thanks the pointers.
After measuring and mixing the two parts of crystal clear for instructed time, the resin is vacuum degassed. After degassing, the resin was poured through 2 centre spruces into the two part silicone keycap mold. There is also a 3rd spruce for air to escape. I kind of squished the sides of the mold to help some air out. One mold was briefly vacuumed again and another was just left to set. The mold that was placed in the vacuum seems to have come out better. The cap is complete, there are still some bubbles in the resin but they didn't dramatically alter the form. The other key wasn't filled enough.
Another problem with the crystal clear is tackiness. I'm not sure if it is poor mix ratio because of the small amount we are using, temperature or just too quick demolding time. Our double vacuumed demolded pretty tacky still after almost 24 hrs. strangely enough the second key did not come out sticky but was removed at a similar time. Slightly baffling.
Anyways after doing more searching I have decided to try a few different products. A different silicone and a non clear resin, which are apparently easier to work with, and some syringes. Also likely invest in the pressure pot.
Now if only my PBT Caps would show up in the mail I could do some sculpting!
Using small cups and measured on a gram scale.
