How much do you push the wood into the blade

Recently I have started scroll sawing again - after a gap of maybe 6 years. I find that I am too afraid of pushing the wood into the blade for fear that the blade may break. As a result, it takes me way too long to saw even a few inches of 3/4" pine.
I see on Youtube videos that folks seem to be able to cut twice as thick wood in seconds. What is the secret here? Am I not pushing the wood into the blade hard enough? How can I tell when the pressure is enough?

Also, how do you know a blade change is needed?

Thanks to all those kind souls who reply.

The only way I know is to break a few blades. You will soon get a "feel" of how much pressure you can use. And, of course, it depends on the size and thickness of the blade. Don't worry. Everybody breaks a blade now and then.

I am using a #7 Olson PGT blade. And I confess, I initially had the blade upside down and was puzzled when a new blade wouldn't cut the soft pine. I then had to look closely at the teeth and saw that they were all pointing upwards (instead of downwards).
I guess, I will have to scroll saw a lot more to get a feel, like Planeman40 says. When the blade cuts, there's a different sound that the blade makes as opposed to when it is not cutting. This is what my limited experience has been so far. Comforting to know that blade breaking is not that unusual. I thought I was doing something wrong.
In time, my dumb questions should cease to exist.
Thanks again to all replies.

A rule of thumb on any cut, on any machine, is that you let the blade do the cutting… the purpose of your hands and body position is to keep presenting the workpiece in-line to the blade.

For a scroll saw, my recommendation is to rest the workpiece against the moving blade… allowing it to make a very small entry cut - almost an abrading cut, if you will; then, lightly increase the pressure so the teeth can being cutting the wood fibers. Thereafter, the blade will let you know when you're pressing too hard. Finally, invest in high-quality blades… they are tougher and will last longer, and save you time, in the long run.

Good suggestions. Do you use Flying Dutchman or Olson? Currently I am using Olson PGT but have hear and read on the internet that FD blades are equally good? Have never tried them though. My goal is to have just maybe three sizes of blades instead of the mish mash I have at the moment. These should be able to handle from very thin plywood upto about 1.5" thick wood. Any recommendations regarding which blades I should stock are very welcome. Thanks

Practice Practice Practice! I too stepped away from scrolling for about 20 years. I broke out the old Craftsman about 3 years ago. Only took about an hour before I knew that I needed something new. Didn't know if I was gonna keep with it this time around or not so I didn't wanna spend a lot of money. Went with a Porter Cable. Much better than the Craftsman. It's still not the best saw, but it has worked for me. I will be stepping up again soon. I use Olson blades bought from Sloans. They work pretty good in my opinion. You can also download an Olson blade chart from Sloan's site. It will help with what blade is needed. I bought a pack of the their "test tubes" and made my own blade caddy out of a maple tree that fell on my sisters house.

I cut a lot of 1/8" and 1/4" plywood for portraits, and it only requires a feather touch to cut that stuff. I recently had to do a bunch of 3/4" and 1" thick pine lettering, and that stuff required a lot of force to cut through (and wore out the blades a lot faster). It really depends on what kind of material you are cutting - you will get a feel for it.

As for blades. I used to mainly use Olsen blades… until I tried some Flying Dutchman blades, which is now all I use and highly recommend.

Cheers,
Brad

Practice on different types and thickness of wood. You'll get the feel of it again. If you think you need to push too hard, maybe you have the wrong type of blade, or a dull blade. I don't use my scroll saw to often, so I buy the dime store blades. If you want to scroll saw on a regular basis, you will want to get the Spiral Scroll Saw Blades. You can achieve some effects that the straight blade cannot give you.

I am at a scroll saw for hours every day. I use blades until they break and as they dull I have to push pretty hard. Make sure the blade tension is good. You should hear a high pitched "ping" when you pluck it.
I use this same blade, Olsen PGT #7 or #9 for cutting 3/4, and thicker, cuts. They last a lot longer than the Flying dutchman blades do on wood this thick. They cost about double what the Flying Dutchman blades cost though.

I don't do a lot of scroll sawing…but I have had the privilege to watch a true master at work. He made just about everything he did out of red oak. My impression is that scroll sawing is not something you hurry thru. I never saw him break a blade, but he sure changed them when they needed it. The biggest thing was knowing when you had to slow way down to let it cut {tight turns??} and when you could go ahead.
With woodworking in general those that are the best appear to really like what they are doing and are always seen to be "taking their time" and just enjoying what they do. I have some friends that take half a day sharpening chisels…..Personally, I am not that way. I don't enjoy sanding or hand planing or slowing down to "enjoy" the work. That's why I bought a saw mill. Best of luck.
