Hello and welcome to the Addiction!
I paid $11 for my first scrollsaw, But that was 60+ years ago. I still have it and it still works, running about 50 years on homemade parts, but still runs. I use it on very light cutting about once a year for the heck of it. I have worn out 2 other saws in between.
You will find all kinds of help and advice here as well as Ideas and patterns!
There are no "dumb questions" although I have seen stupid answers! Everybody does screw-ups, do NOT worry about them most are repairable and the rest can be useful for the campfire!
Scrounge up some free wood for the practice runs and have a great time. Make the "nest" comfortable for you. What works for someone else does NOT matter; what works for you does. Use a small shop vac and jury rig close to your saw to help with sawdust removal, some saws even have a vac port.
The forum will give timely answers -- advice- patterns- ideas and a load of crap to everyone! None of the garbage is personal-- just noise!
We do like to see work, not everyone can be the world's best, do NOT worry about it! If you like it; it is good enough to show us!
