In experimenting with some scales, even a hair dryer will produce enough heat to allow slight re-shaping of plastic and celluliod scales. I used one to gently heat several sets and ease them back into the shape I wanted, then rinsed with cold tap water to set where I wanted them. Another tip that helped me was to use something to maintain the proper space in the middle of the scales; a q-tip stick (cotton pulled off of one end) worked pretty good.
Just be careful if you opt for a heat gun. It may produce too much heat and will be really detremental on light-colored scales (may yellow them).
I am not any sort of expert so use at your own risk; just my personal experience!

You may also want to search on Traveler.
He posted or re-posted something recently on this topic using an oven and popsicle sticks.
Hope this helps....I have a fairly new razor I need to fix the scales on too. I will likely try a hairdryer first and then the oven as a follow-up if needed.
I have had success with dipping them in boiling water and then holding them to shape in a cold water dip. (No, I didn't put my fingers in the boiling water, douh!)
Thanks. It's THIS thread. Sometimes the search terms are a little hard to pin down.Quote:

Just dipped a razor with warped black plastic scales in fresh boiled water for about 10 secs - manually held them under cold water for about 10seconds after that. Just the shape they need to be - only thing is the black has gone milky coloured in patches and won't polish out. Not the result I had hoped for - what did I do wrong? Suppose I need to do a little bit more aggressive polishing now to erradicate?
I tried some really hot (not boiling) water on a razor tonight, and while it worked really well it did discolour the scales. I can scratch away a little of the discolouration, but not all. The scales were uniformely black before the unwarping, and now they are mottled brown.
Has anyone else experienced anything like this? Unless someone here can tell me it's fine I'm tempted to get rid of the scales in case I've started some celluloid rot-like reaction.
You may have gotten them too hot.
May sound odd, but take some metal polish to them and work in in with your hands (vice a cloth). I use eagle one polish for billet (motorcycle shops generally carry it) but most fine metal cream/polish will work.
As you rub the polish in, it usually will start to feel tacky as it starts to dry. Add a little more and work it with your bare hands a bit longet until it starts to feel tacky again. Rub it fairly quickly (builing a little heat with your hands) and then wipe clean with a cotton cloth (old t-shirt).
It may take a few times to clean them up, but it has worked well for me anyway. I finish up with a little warm water and dish soap. Be sure to run a cloth between the scales to get the residual out.
Good luck!

Thanks, I'll try that. :)
I think just by looking you may have cooked a little of the natural oil out of the horn. I would think after you polish them up you will be fine.
I can say for sure the boiling water trick works for horn (at least temporarily). I Soaked the scales in the boiling water for 1 minute, pulled them out, put a tapered chopstick inbetween, flexed them, and then into cold running water while flexed!
You definately need to be holding the scales in the desired position when putting them under the cold water. You can't just mold them then harden. And It took me about 4 tries to get it right so... try and try again!
Metal polish worked a treat, thanks for the tip. The scales aren't horn btw, definitely some sort of synthetic material.
Has anyone tried successfully re-shaping fancy Dubl Duck scales? I'm worried about the effects of heat.
