bending blades

[newholland]

I purchased a really nice old Delta single owner Model PM 1512 24" scroll saw. I keep bending blades and obviously not installing correct. Can some one help. Also I purchased this for my natarsia projects and need to use # 5 blade. Any suggestions.

Which direction, and at what point are the blades bending? How much bend?

You do not have enough tention and pushing too hard into the blade.
The blade should make a nice high ping sound or should not move side ways more than 1/8". Have good speed and push vey slow into the blade, let the blade do the cutting they say. You need patience when scrolling.
