I use a one size down dodger as a template, i.e. a 4.5" dodger as template for 5.5" dodger tape. I put some scotch tape doubled over between my template and the dodger tape. I use an X-acto knife with new blades to cut the dodger tape. All in all a real pita but the end result is close to perfect.

Start asking around, you find a source there and you're golden.
