Simple overwind protection for Constant Force Spring

Can I use the attachments of the ends of a constant force spring as overwind protection? I am using a small (1 in-lb) 100" long constant force spring and I am trying to avoid the complexity of using a string on a spool to avoid overwinding the spring. Althouhg the typical specs for a constant force spring say to leave 1 1/2 turns on the storage and output spools, do some engineers use the end connections of the spring as the overwind protection? The spring is being used to propel a spinning wheel in a piece of wall art. Thanks for any help for the newbie :-)
