Removing Parts from the Sprue

One mof the most essential skills for any modeler, which must be mastered early is the art of removing parts of the sprues of plastic kit arriving. If the first meeting, much time can be save in the development of a model for the painting is done correctly. In this tutorial I'll make a few simple ways to removing from sprue.


1. Thrush to delete (in this case, a trough of a Master Grade kit Zaku II Ver 2.0).

2. Cutting tools - a couple of plastic knives (no cutters or nail clippers) and a knife are a must.

3. Suns Barn and sticks (preferably 2 or 3 different degrees of fine to very fine)

Step 1: 
Select the part you need to remove following the instructions provided with the kit. In order to eliminate, as shown, the item must be cut from the corridor at the points where the arrows point

Step 2:

There are two ways I recommend to cut parts. Thrush away the first way is just above the heel. The reason you need to cut the part out is that you will have if you do it this way. More control over the appearance of the piece cut too and the risk of crushing the plastic if you cut and ultimately damage to the side to make holes in the trough is the side walk runs.

Step 3: 

The other way is halfway between the outer container and cut the piece as shown in the following figure. It's basically the same method as in step 2, but allows greater control over how the piece is removed and there is less chance of damage to the workpiece at this point in the assembly process.

Step 4: 

Once the piece is removed from sprue, you can start removing the excess plastic. For this it is necessary to use the knife and cut so tightly to the part as possible. When cut, it is best to quickly cut the plastic exercise. Slowly the pressure instead of Applying pressure can reduce the risk of damage to the part because plastic can boot and a hole to be filled with putty later.

Step 5: 

Once the excess sprue is removed, it is now time to remove the left. The last bit of 'nubs'

Step 6 :
For an alternative way of removing the 'nubs', shave most of the plastic off and then lightly sand it back until it is flush against the kit piece. This is especially handy for curved surfaces where shaving with a knife sometimes leads to gouges and holes due to the curved surface.
