Okay I will try that! Could you point me to what part exactly it is on this manual? Thanks https://pdf.lowes.com/useandcareguides/000999375004_use.pdf

I don't think that is the issue because the saw is relatively new, only been used for about a month now and all of the parts are intact. I am not sure if I tightened the blades too much, or somehow damaged something holding the tension in place?

Hello, I am fairly new to scroll sawing and I am currently working with an 18" Porter Cable variable speed scroll saw that is being lended to me. I've used it for probably 6 hours or so, but today I went to use it and I was struggling to get my tension correct with a plain end blade and something broke. Whenever I try to run the machine, the tension instantly releases. This has broken two blades, and no matter what I do I cannot tighten or loosen the tension and get it to hold when I run the blade. I am not sure if I broke it by applying too much tension earlier on, or how to fix it because I do not know exactly what is wrong. I am waiting for a response from Porter Cable, but in the meantime are there any suggestions or does anyone know what I did wrong/what piece I broke? Everything looks like it is not broken, but I do not completely understand the mechanics behind the tension of a scroll saw.
