1) These are the masters for the track
runs, curves and spares which were cast from
individual links. They are ready for final de-glitching.
I use Mr. Surfacer to fill in the joints and to
prime the surface. This material is a light to
neutral grey colour which allows flaws to show
up easily.
2) Mr. Surfacer is used to fill in any gaps that
there might be between the links.
3) Test-fitting
the curve around the drive sprocket.
4) First the lower hull was sprayed with iron
oxide coloured primer. This was done as I am
doing a late production vehicle. I mixed up my
own paint using Model Master flat enamels. Once
dry, the hull was washed with a very diluted
mixture of Humbrol yellow-brown. You will notice
that I filled one of the mounting holes for the
idler wheel. This was done to allow it to swing,
thus allowing me to close the gap between the
runs of track.
5) The wheels were washed with the same diluted
mixture of Humbrol yellowish brown Following
this, the edges were highlighted with a mixture
of silver 'Rub-N-Buff' and graphite. The face of
each wheel was also given a light rub with
graphite.
6) Aligning the first set of roadwheels using a
straight edge. I checked them in all dimensions.
7) Positioning of the
outer road wheels. The drive sprocket, idler
wheel and idler arm are not glued at this point
8) Test fitting one of
the first test shots. The flexible resin
conforms to the sprockets easily. I had made
moulds for short runs of rigid resin and even
cast them. Since these track sets are going to
be sold, I thought it best to make them very
easy to assemble hence., they evolved as two
pieces of flexible resin..
The two identical pieces are cleaned up and
glued end to end with ca. I use three sections
of brass tubing as a bed for the tracks to lie
upon.
Crawling across my table...the entire run.
NEW PRODUCT ALERT! Mr. Surfacer now comes as
resin primer. It smells like it is cut with
acetone which will give it a bit more bite. The
'ol scratch test found it to be quite durable.
The tracks were first sprayed with a dark
reddish brown acrylic paint. When dried, a wash
of thinned down Humbrol yellow ochre was applied
and let to dry. Following this, I mist coated
the tracks with a mixture of rust and the same
ochre to blend the colours a bit.
Graphite dust was rubbed and brushed onto the
tacks.
The painted run was glued end to end to complet
a loop.
The complete track was streatched onto the
wheels. CA was applied to the top of the wheels
and the tracks were pushed into position with
shoprt pieces of a glue stick to get the needed
sag. By the way, I am building two Tigers at the
same time. One will be the standard early
production model with a yellow base while the
other will be a late production version painted
in red oxide primer.
