Re: Old dog learns new trick
Greetings Bill,
Try throwing the soldering iron away! I use a new scalpel blade in
it's handle to cut all films including Y2K2. The handle gives more
control in case of the shakes and I cut into a soft pine building
board which helps to stop the blade from wandering by trapping it as
you slowly move along. The only time I use a cautery is with F1D
props. With thick films like mylar, you can turn the wing upsidedown
and use a steel rule as a guide for the scalpel along straight
sections. All other lighter films can be cut from the top.
The edge produced is neat and clean and easy to tidy up afterwards.
Nick.
