Hi JWH,
Welcome to the group.
The bouncing can be caused by multiple things.
Make sure your guard is adjusted properly, if you're using it, if not, you should consider using it until you get the hang of things.
Make sure you hold your wood close to the blade, and make sure your blade has the right amount of tension.
I would recommend you visit
Rick Hutchisson's website for his video tutorials and tips, you'll find good information there to get you started.
Don't hesitate to ask us uestions, we are here to help you on this wonderfull journey that is scrolling.
Do not get discouraged, it isn't that hard; you just need to get the hang of it, and this is the place to get the info to point you in that direction.
You'll have to be a little more specific with your problem with the patterns.
Regards,
Marcel
