Hello, I am a newbie to the saw recently. As a result, I have spent a lot of time reviewing all the information that I can find on using the saw. Steve Good Has a great Beginner Scroll sawing videos on youtube. In the second one, around the 4:35 timestamp area, he explains the issue with cutting "straight" with a scroll saw. You can find that video here: https://www.youtube.com/watch?v=nxx-JuQJsms. Others have also explained it the same or similar to Steve's in the video. I bought the scroll saw I have years ago when my kiddos were little, as a result, I didn't have a lot of time to work with it and gave it up. However, I do know that part of my issue/frustration was that I couldn't get it to cut "straight"!
