[SML] SML] question for router wizards

[info at wjsstudios.com]

If I understand your description, it may be an issue changing the base plate size. As the base gets larger your ability to follow detail on the pattern may be lost. I would make a pattern for each shape and use a "pattern follow router bit" or a Flush trim bit.  http://www.stewmac.com/Luthier_Tools/Types_of_Tools/Routers_and_Bits/Bits/Ball_Bearing_Router_Bits.html?utm_source=google&utm_medium=shopping&utm_campaign=2016-12-gp&gclid=CKWHpL6V_NACFcS1wAodV3wP-g

 I want to router cut some ply. The shape is composed of several
 different ellipses but shouldn't matter. I plan to make a template of
 mdf - this is in the range of 4 x 10 feet - and I'd like to cut
 "concentric" versions of the shape all within 2-3 inches of the
 smallest. I thought I'd make template based on stock router base and
 smallest piece, and for larger, make larger round router bases. I
 never for a second thought this was a new idea so went googling and
 can't find anything on doing this. Lots of different sub bases - but
 none that would follow a template on this scale. I could look at two
 rollers or pins but seems nothing would be as simple and safe and
 accurate as larger round bases.
 
 Probably missing the obvious, but most seem much more expensive for a
 one time diy home project.
