CRAFT-VAC SUPPORT INFORMATION
If you plan to produce quantities of forms or molds, you may want to build a base plate to register the Craft-Vac to the hot plate. This will keep everything in line and centered to get the best result each time.
PLANS - If you built your Craft-Vac from plans, you may have just under 8" of Aluminum angle metal left over from the build. That can be used to make L brackets as shown in the illustration below.
KIT - If you bought the Craft-Vac in kit form, you can purchase L brackets from a hardware store to accomplish the same result. Wood blocks or even wine corks can be use to retain the registration of the hot plate and may actually work better and save money at the same time.
The Craft-Vac JV may require more height depending on your hot plate. If the length of the standard legs are not high enough to properly separate the plastic from the heat, riser stilts can be made using the same 1"x 2" wood used for the frame as shown.
For the DIY build, the riser does not have to be 3 solid layers of wood. The middle layer can be spacer blocks as shown to cut down on material and weight.
For the DIY build, If you were confused about the barbed fitting sizes, I hope the description below will clear up any questions. If you cannot find the exact PVC fittings, there is more than one way to adapt the barb fitting to the 1" coupling. These are a common sizes and should not be difficult to find.
