Finding AMT 72 C-10 and Blazer not to scale

[64SS350]

I may be a Johnny come lately, but has anyone else noticed that these kits are not to scale and out of proportion?

How often do you find this in other kits?

[Mark]

Any specifics?  

[tbill]

You may have opened Pandora’s box …….

[Plowboy]

How so?

[Oldcarfan27]

Fine to ask the question, but you need to explain where you find discrepancies so we may agree or disagree with the assumption.

Did you measure something that wasn't to scale or something appears wrong?

I have the Blazer Crew Chief kit if that’s the one you are talking about? I haven’t actually measured the body, but it looks pretty decent to me. There are definitely some scale issues with some of the parts.? Best to get a donor kit for parts or do some scratch building. My build so far…

The discrepancies I have found....

The blazer, according to 1:1 dimensions I found online, is too short. The wheel base is right on, but short front and rear.

The C10, from the bottom body line to the bottom of the panel appears different compared to 1:1pics. The bottom rear quarter angle is also different from 1:1pics. Let's not forget the engine bay is all wrong. As far as length, I haven't checked that yet.

Is this what you are looking for? I have it listed in the Trading Post section. It is factory sealed.

I'm not looking for, "I am finding that..."

I'm posing a thread to discuss the incorrect scale of the kit.

Thanks though 

[Plowboy]

When you measure, are you taking the actual measurements and dividing by 25 or using the 1"=1mm method? The 1"=1mm method is not accurate on measurements such as wheelbase or body length. It's OK on short measurements like a wheel. But, not on longer measurements. 

[64SS350]

I've never heard of the 1"=1mm method, of course that would be inaccurate. The mathematically correct way is to divide the measurement by the desired scale.

[Plowboy]

Something that needs to be taken into consideration concerning the C/10 is when the tooling was made originally. The C/10 was actually made from a GMC that was done over fifty years ago. I don't know if the Blazer came about in the same manner or not. Either way, it's old tooling. 

Exactly how short are they front and rear?

[64SS350]

Actual OL=180.5", =7.22"@1/25 scale.

The kit measures (without having it in front of me) 6 13/16- 6 7/8"

[Plowboy]

Did you measure at the center of the model with the bumper installed?

[NOBLNG]

It looks like it maybe needs a little extra length between the door and the rear wheel opening? The size and shape of the rear side window is a little off, and the rear profile could be squared up a hair? ?‍♂️ All in all, the body looks fairly accurate to me. I have no idea about the C-10.

I'm comparing 1:1 dimensions given to the kit itself. Just wanted to see how prevalent this is among other kits. Seen many posts and heard many conversations about kit incorrectness.

Thanks for the pictures, that helps a lot!

I too see the shortness between the door and the rear wheelhouse, but if the wheelbase is correct as he says, I can't see how to fix it.

Roof looks a little short in the back too. Possibly the window is too big.

Might just have to be a case for "eyeball engineering", if it looks like the 1:1 then that's close enough. It probably would take a little stretching and shrinking to get the desired look.

I do agree with him that the underhood details are lacking in both kits. Firewall openings are huge and the inner fenders are just plain wrong on the pickup and would require major surgery to correct.

But that's why we're modellers, you know. Fix what you can and pass on the rest. Not everybody has the skillset to do that much rebuilding and that's OK. It's about doing what makes you happy, not stressing over what's not microscale correct.

My plan is to make a Suburban out of two bodies, but I have managed it in a way that the one body can still be used for something else.

The pickup engine bay I have a solution for, I will eventually cast it.

[Jack L]

when making that Suburban the length behind the rear tires is longer than on the pickup

[64SS350]

Yep

 

[Tabbysdaddy]

You can pick any kit and you'll have a bunch of people telling you all kinds of stuff that is wrong with it.

[Oldcarfan27]

If you're going to kitbash a Suburban, you've obviously got the ability to correct the shortcomings of the original kit.

Model On!!

I would suggest using the pickup to start the conversion, as there isn't much on the Blazer that is close to the Suburban - except the chassis (4x4) and the grille. But that's just my opinion.

Exactly…that is my philosophy.

I have not measured anything, but from the measurements Karl posted, the body is anywhere from 8-5/8” to 10-3/16” short on a 1:1 (approx. 3/8” in scale). It looks close enough for me and I would not attempt to fix it myself.

I hope you do a build thread on it!?

[64SS350]

I plan to do a build thread, yes. I just got a notion try this build,I made some preliminary cuts, playing around with it here and there. I recently shortened my own 72 C-10 bed, so this is a good next step!  Got a lot of projects this year around the house and at the bench.

I've been waiting a couple years for some resins to be ready that aren't done yet. I know Robert Burns now makes one, but I'm not willing to put that much out right now, though a few years ago....
