How To Cast In Resin Part I

The Tools:
     Each month, I plan to cover, in-depth, "How To Cast Resin" miniatures.  A few things to know in the beginning are the tools of the trade.
#1)  The mold:
     Molds can come in all shapes and sizes, but a good, long lasting medium for molds is silicone rubber.  I will cover more about silicone mold making in a future post.  Unitl then, check out this site for excellent wargaming molds:

#2)  The pressure pot:
     A pressure pot can be acquired from any tool vendor on the net (see links) and will likely need to be modified right out of the box.

Pressure Paint Tank Pot
Grizzly H6330 2-1/4 gal. Paint Tank
Here's mine:

Some additional parts you may need, depending on which tank you purchased:
          a) Ball Valve
          b) Pressure Regulator
          c) Gage and misc fittings to adapt all of these together
#3)  The resin:
     A no-brainer here, but I will provide some links of where to find good resin.
#4)  Postage scale:
      Most resin will be mixed either by volume, or by weight.  Either way is accepted, but a more exact way to measure is by weight.

Digital Postal Shipping Postage Bench Scales 35 lbs

#5)  Cups and mixing containers
     You will need a stock of paper/plastic cups and stir sticks/spoons to mix your resin up in.  Keep it cheap here, because nothing gets re-used in this department.
#6)  Optional Step:  Vacuum Chamber
     I use a vacuum chamber to degas my resin prior to pressurizing.  I know a lot of people into resin casts that do not perform this step, but for me, I already have the chamber for degassing silicone and it only takes a few extra seconds to do.  I got my setup on ebay from a seller named pvac-1526.
Here's setup if you're curious:

Hopefully this is enough information for those interested to get a good start on tools and equipment.  Stay tuned!  Any comments?  Feel free to post!


  1. Great post! This is probably the next area of the hobby that I am interested in getting into so I am keenly awaiting future parts to this series!

  2. Very good post. I'm currently working on sculpting models actually. Not too good yet, but step by step as they say. Will be trying to make moulds and resin cast in the future. Will try to do it without the pressure pot at first and see how it goes.

    Anyway, look forwards to reading your continued posts.
