Yes, you can.
I was looking into this recently and some informaton from this very board that appears to have been lost. Google had the info cached and I plucked it from there.
I quote:
The plastic that Verlane uses is LDPE. Which stands for either, "low density
poly ethelene" or "low density poly eurathane" can't remember which just at
the moment. Verlane kindly gave me a sample of it. It works realy great!
Just place it over a drawing (mirror imaged) of your patern and then engrave
the lines with an oscillating engraver (not a rotary engraver). These
engravers are less than $20 at hardware store. Scourcing the plastic can be
a bit tricky. It is used by the people who make prosthetics. So find a
medical supply company. I've been told that you can also heat it with a hair
dryer and then shape/mould it around the swell of a saddle fork for
transfering tooling paterns onto swell covers. Have not actualy tried that
yet, but given time I will.
I have taken this information and obtained a piece of .020 LDPE (low density
poly ethelene), tried it, and it works great.
I cannot take credit for this information because, as I mentioned, it is information that this board lost which I was able to gather from Google's cache so thank you to the original posters of this information.
Also, as I discovered on this search, if you search Google for something that did not reappear here on the board, you might still be able to see it in Google by selecting the cached link that appears below the individual search results.
