Now you have cast
you first figure you must cut away the sprue and make
sure that all the parts are ready to file and glue.
This stage can often be overlooked, but that would
be a mistake.
Tools you will need when removing
parts from the casted sprues: (Fig.1).
- Flush Snips (Cutters),
- Blade Saw,
- Modeller Knives with replaceable
blades.
(Fig.2) Some sprues have a protective
frame surrounding the parts. This can now be pulled
away from the parts to allow easy access to begin
removal of figure parts.
(Fig.3) When cutting with
flush snips always turn the flat part of the snips
to the part you want. This results in a cleaner
cut.
(Fig.4) It is very annoying to find
that when cutting away the sprue you have accidentally
damaged a piece of the part you want. To avoid this,
it is advisable to cut at least 2mm from the
part especially when cutting thicker sprues.
You will notice that the snips will push towards the
part as it cuts so keeping back from the part avoids
the danger of damage.
(Fig.5) Some sprues connected to
more delicate parts can be thinned by scoring with
a modeller's knife and twisted off or cut off completely
by the blade.
Very thick sprues can be a bit too
much for normal snips. However if you score them with
a blade were the parts meet sprue and then twist off
with the aid if a pliers you can overcome this problem.
Make sure it is well scored
before doing this or you could wrap or damage the
part itself. Some might prefer to use a bladesaw
for a cleaner cut from sprue.
Tips to remember:
- Bend protective sprue away from
parts.
- Turn flat part of snips to the
part you want.
- Cut at least 2mm from part.
- Score sprue with knife to protect
delicate parts.
- Thicker sprues may need additional
scoring or even the use of a bladesaw to weaken
the sprue and prevent damage to the part.
