Welcome to the forum, Laura,
You can find a wealth of information here and lots of patterns to practice with.
The members are really friendly (for the most part) and generously offer tips,
help, and good conversation.
You may want to consult a chart that recommends what blades to use for
different wood stock but, these are just recommendations. Everyone finds their
own comfort zone. I use the 5R almost exclusively and can cut as thin as 1/8" and as thick as
1 1/2" with that size blade.
Here are two links to the type of chart I am talking about.
http://www.sloanswoodshop.com/PDF/blade%20chart.pdfhttp://www.scrollsaws.com/General/BladeChart.htmlAs a new scroller, you may want to try some spiral blades which cut from any direction on
the blade. In other words, you can cut forward, reverse, left and right with-out turning the
wood because every side of the blade has a cutting edge. If you experiment with them
early in your practice phase you may get better with them than someone like me that
got used to the flat, no-pin blades and struggle with the spirals.
Have fun and show us your projects, please.
God Bless! Spirithorse
