Tracksetta's are really useful. Stick to the more useful radi 24" 30" 36" and maybe larger depending on the area you have. Don't bother with anything smaller than 24" a lot of loco's won't go round these small radi.
You might want to make a trammel using some thing box wood and a nail as the centre, you can then measure off radius points drill a hole to accept a pencil and you can cover most useful sizes, and those that you don't have.
