From fabrication to installation and dealing with shop activities, what everything day problems do you run into?
Such as cutting a straight line on a ruler, putting transfer tape on large prints, weeding out vinyl, etc.
I am curious and perhaps the members here can help resolve the issues.
The solutions to your three problems are [in order]:
1; Learn to pull a straight line without a ruler. The operative word here is 'pull', just like a brush, you set the knife down out in front of you and pull it towards you. Cut longer than your arm? Learn to step back faster than your pull. Pulling a line is a fundamental skill in the sign business.
2; Tear it and pull it off in narrow[er] strips. No need to fight all that adhesive at once. It comes off in pieces just fine.
3. Pay attention to what you're doing as well as learning just where to put your fingers on one hand while doing sort of a jerk/pull with the other. Of the two paying attention is usually the more difficult..
As for myself, I have no particular problems with anything other than a tendency for absentmindedness and wandering attention. That and I'm not much for janitorial work.
