The Perfect Sintra Curve

I've been reading different posts and looking at the pics of the BF chest armor.

My question is about the curves. I have the templates cut and transferred to sintra. Now I need to curve it to match my body.

How does everyone seem to get the perfect curves on the armor? They all seem uniform and accurate.

Do you just heat the sintra and bend it a little at a time or do you form the sintra around something? I searched but did not find a conclusive answer.

Any help would be greatly appreciated.

Great job everyone, there are a lot of clever people here.

Well, to be honest you cant get the perfect curve with sintra. The curve is a sort of 3d cup curve, and it doesnt really curve like that. So, that being said.

For a single curve its sort of an angle. from the outer upper corner to the inner lower conCAVE spot (first curve up from the lowest INNER ANGLED part of the armour plate.

Using a trash / waste can (look at the trash can armour thread) will give you an idea of the closest curve to 'right. The only difference is after that curve is in the armour the upper curve, which is 'bow shaped' then has to be curved inward (towards your spine for lack of a better example).

Which isnt possible with sintra, unless you boil it and set it on someting that shape. But if you had something that shape, you wouldnt need to use sintra ehh?

I hope that helps. My suggestion is to use a trash can in stead of sintra, if for no other reason than to get the angles so they all match, and make a nice 'flat' front.

Remember that the tighter you get it to your vest, the better the armour looks. It creates a 'plane' instead of multiple planes.

good luck!

actually Seeker has a video floating around here somewhere where he makes a chest piece from start to finish and he's able to get the perfect curve on it. He used a master mold (I think it was made from acrylic, but bondo would work too) that was a perfect copy of what the armor should look like. He heated his sintra up so hot that it was downright flimsy, then he stuck it on a huge cushion and pushed his master mold onto it from above. Just press and hold and it'll be the perfect shape, I guess. Making the mold will take a long time though
 
I took a 5qt glass lid I had and after I boiled the chest piece in the pot, I just laid it face-down inside the lid. Instant curve.
 
I've done this before, and it works wonders. (y) I never would have believed sintra could look that good.

Just make sure it's heated to the point of floppiness. Also make sure you get the sintra piece aligned with the mold your using to shape it, or else you'll get annoying dents/creases on the edges.
 
This is the second time I've seen a reference to making a mold with Bondo and I'll admit, I'm a little lost.

(I'm also a complete neophyte and am picking up my first batch of Bondo tomorrow.)

I want to try Seeker's method for shaping the Sintra, but am slightly confused as to how a mold like that could be made from bondo. Everything I've seen is that it's more of less quick setting slime. How does one get the shape right and then subsequently the curve?

I apologize for the complete ignorance in the question but I've yet to see this answered in my searches.. Gotta learn sometime, eh? ;-)

Thanks!
