So is THIS The RIGHT STUFF... Naphtha Head Shrink Question.

[sprytel]

I remove the head from the Naphtha, rinse it in hot water, dry it off, and try to get that last little extra compaction if I can by brute force. Then I install it before it hardens up.

I just did Burnham recently and I was really happy with how she turned out.

In my experience, the continued shrinking is pretty modest. 10% maybe? In any case, I wouldn't remove it early. I have never had it shrink "too much"...

I just picked up some Naphtha and am going to have a go at shrinking some heads... curious about how much a head will continue shrinking when removed from the Naphtha (should I remove it before it is at the exact size I am looking for?) And, once removed, should I wash the head with hot, soapy water to remove any traces of the Naphtha, or should I simply allow it to evaporate.

Finally, will this method work on Marvel Famous Covers heads?

Thanks.

Another neat trick...........once a head shrinks and hardens, you can heat it up and manipulate the shape to a degree. These are Playmates Kirks.

That's just too much shrink! Acetone won't even shrink stuff that much.

That's what I was guessing was the issue.

So, 12 inch heads won't shrink to 8 inch scale (at all)? Not even Mego 12 inch heads? I was just wondering?

Probably because of the size of the head and the density of the vinyl the naptha has to affect?

I’m having a hard time getting my Worf head with hair to shrink any further. I’m going to continue to soak it and try a Worf head with out the hair

^^ That's what I've been thinking too, in addition to the (unknown?) destructive effect on the vinyl over time.

Anyone try this hack on PVC?

Jumping in here.

Anyone shrink the Bride and Creech heads from the DST/ EMCE line? I was thinking of doing it and how long would one recommend to soak and dry in Naphtha? How much is meeded to soak?

That seems to be the question. Since the heads will continue to shrink after the soak, I think it would be best to go slow. Nevertheless, others here know more than I. As a custom head molder, I would cure to desired size, and make a mold at that size. If it continue to shrink, well, at least I still have my mold. But, that is just me.

has anyone tried shrinking the weapons that come with the Playmates figures? I've had a phaser soaking for 3 days and it has not shrunk at all

thanks. I waited a few hours and then did it. it did seem to misshape for a bit after I squeezed it on but went back to normal after a few minutes

If you're popping it on a new Mego body I have found that the neck plug is almost airtight and it doesn't want to let the head "breathe" to reshape faster. I soulved this by putting the head on warm and lubing the plug a little so that the head slides on without too much squeezing. If it hardens a little out of shape hot water makes it pliable again for adjustments.

this was after 3 days soaking. pretty close in size now. how long do you let it cure before attaching it to a body?

Sometimes I don't wait at all, just warm it for softness and pop it on:-)

Two days is about right, my first effort continued to shrink a bit after removal as it cured. It's amazing stuff.
