In automotive modeling, few things add visual impact to a model kit the way a realistic open grill does.
on many occasions, there are photo etch sets available to give a similar outcome, but on some kits the photo etch just doesn't look right, or its not in the budget.
i will go through the steps on a 62 bel air grill to show you how i open them.
you will need:
a flat file
hobby knife with a sharp number 11 blade
a needle, pin, or sharp pick
find grit sanding stick
patience ( it is not a quick process to get right )
a dremel with a sanding disc also comes in handy if you have one but if you don't i have done this one without to demonstrate.
Starting with this
i trim off the sprue using a razor saw, you notice i left the chrome on this for the process. the chrome layer actually helps you gauge how far you have to go when you get close to the end. so if you are going to strip and rechrome, wait till after its opened.
I start removing material from the backside of the grill with a file, it will take a while. Make sure you work slow and evenly across the whole back side so you dont have any spots thicker than others.
Here is where that layer of chrome helps you, once you get close to 'breaking through' you will start to see areas with the chrome peeking through.
Put the file away and grab a fine grit sanding stick instead. work gently, let the sanding stick do the work. if you are forcing it to cut deeper then you run the risk of bending / breaking the grill.
Now use your hobby knife of the pin to gently trim any of the remaining chrome from the grill openings and clean up the edges.
The completed grill, if you work carefully enough you wont even have to rechrome it. it adds a bit more realism than a black wash and is cheaper than photo etch.
Practice on a grill from the parts box until you get comfortable, then have at it.
its only plastic....
cya next time
