65 Chevy Stepside Box Stock Build: How I am Doing it These Days

OK I am sick of the AMT 69 Chevelle rebuild so I put it aside am and going to build something a lot easier. A box stock Revell 1:25 pickup...that I bought a few months ago....will fill the bill.

Pickups are easy, I think, because they don't have a lot of trim that needs bare metal foil, have nice large bodies that make painting pretty easy, and relatively square surfaces that make sanding and prep go fast.  I got this Revell "Trucks!" kit, 85-7210, at a Walmart Blowout for eight bucks! OK, no mods, no tricks, just a basic box stock build right?

I imagine if you get 100 builders together they will have 100 different ways to do a box stock build. For me, first thing I do is take out all the "white plastic" (non clear, non chome etc.) and wash it with warm water and dish soap and let it dry. I have read this gets rid of mold release agents and other chemicals on the parts.  In reality, I have skipped this step many times and not seen a heck of a lot of difference.

Next up I go through each step in the directions, cut the parts from the sprues, and bag each group of like parts. Yo!! So: one bag. for the interior, one for the engine, one for the body parts, etc. Sometimes I will leave a bit of sprue somewhere to help with painting (more on this next time, and I have talked about this before).

I like doing prep work in batches, like trimming parts from sprues, otherwise I am picking up my sprue cutter 100000 times during the build vs. just blasting it all out at once. 

Next it's clean up time....I go through every part--yes, every single one, and get rid of mold lines, flash, ejector pins, and any other gremlin I can find.  Even if I think the part's defect will be invisible! For this I use a series of files and sandpaper, putty, and glue.  And if I work efficiently it goes pretty fast.

This particular kit was remarkably free from flash and mold lines.  However there are some ejector pins or ejector holes or ejection donuts whatever you call them all over.  My understanding is that these are used during the casting process to "shoot the parts out of the mold".  And little disk is visible from whatever is used to do the shooting.

Revell's craftsmen were careful to try to put these ejector holes on a non visible surface, but they can affect parts fit, and they always bug me, so I get rid of all of 'em anyway.  Sometimes they easily sand or file out, but in this case, for this particular body part, they were really deep, so I am using Tamiya Light Curing putty, which dries relatively quickly and is easy to sand out when it's dry.  I apply this, let it bake overnight, and then run some sanding sticks over it.

Sink marks are another thing to watch for.  As I understand this: this is when the cast part "sags" a bit while cooling off.  You don't want these--they look bad, can affect parts fit, and in general drive me crazy. Fortunately this kit didn't have a lot of sink marks; some of the older AMT kits or whatever have a ton, but this kit was pretty good.  Again, light curing putty and files to the rescue.

OK! once the cleanup is done, I will unbag the parts groups and start test fitting.  Here, I am trying out the exhaust/axle/frame fit, because I have seen this be extremely problematic on a lot of kits.  For this build, the exhaust pipe setup wasn't documented well, but it looks like it will glue up OK without heating and rebending, which is nice.

And of course the body needs extra attention, always--this is what everyone sees!  This particular kit has a lot of body parts, I count 13.  Since I want to try to paint this as a unit, I am going to preassemble it and clean it up once glued.

Here's what I have after some gluing.  The hood fit is dicey; it almost always is, and is going to need some more work.

That's a big seam, so big you can drive a truck through it;  But this is a truck, so perhaps you can drive it through itself?  Something like that.  The hood is a 4 piece affair. I know it has to be sturdy or will fall apart when I try to clean it up.  So I glued it from the inside and will let it dry overnight before trying to fill in the above seam and try to improve the fit.  The complex shape will make this a bit tricky, but i figure I will manage.

Next time: prep for paint.

69 Chevelle--Oh You're No FUN Anymore

For the handful of folks following this blog you may have noticed no posts lately!  The attempt to modernize the AMT 69 Chevelle 1:25 kit is driving me the point where, no model making for the past couple of months.  It feels like more work on this build would be a waste of time.

So here's what I have so far.  The body has been worked over a few times, wheel flares added (because the originals on the AMT kit, and I bought two of them) stunk.  OK that was some work, and in doing that, the body began to warp.  So I got out the chassis I will mate this to--from an AMT 69 Olds, that had more "modern tooling", and banded it all together.

In the meantime I went to work on  seats.  The ones provided by the AMT kit look nothing like the 1:1 originals, and leave out basics like the seat headrests, clearly visible on the box art.  The Olds seats are closer, but still not a perfect match.  (Sorry.)  I razor sawed out the center console and glued the seats to it, filling in the gaps with some .01 sheet styrene. Since I am considering probably never touching a plastic model again, this will have to do.

The hits keep coming!  The ejector pins are everywhere in the AMT Chevelle kit.  At least this time they didn't put the pin right over the floor matte.  Lucky day.  This will have to be filed out, and the "carpeting" redone, probably with embossing material.

And of course the priming I did looks like cottage cheese. You have to prime body reworks like this several times, and it only takes one bad round to have it come out like this.  So it all has to be sanded and reprimed.

Overall I am at the end of my rope here. I could spend endless hours on this build, and then have Revell put out a new tool of it that kicks my work's butt.  I am not sure there is any point.  I may put this one up on the shelf again, and then think about selling off my paints, kits, and tools.

And, the molding on the dash and firewall look like they were from the Jurassic period; a lot of work will be needed to get this to an acceptable level of details.  To me this just isn't that fun any longer.  If you don't see another post for a few months this is why.  I am not sure if I am just going to shelve this project or give up on the entire hobby for awhile.
