Ripple effect when cutting on fretsaw

[Jensmith]

I bought some new blades for my fretsaw but using one today I'm getting a ripple effect on the cut which I've never come across before.

It's a pin end blade from Proxxon though the fretsaw itself is a power craft brand. They are 18tpi blades.

Any ideas what could be causing this?

Thanks

Hi Jennifer,
I would try a little more tension, also check your feed speed is not to high and the blade is flexing.

Thanks Mick. I will give that a try. Possibly is the feed rate as I thought the tension was ok - it's quite a high 'ping' when you pluck it.

Are the new blades a different TPI? do you get the ripple regardless of wood thickness?

I dislike prooxxon blades . Two years ago when I start scrollin I bought Several types prooxon pin end blade.
You can't cut the board straight
You don't have control of cutting
No precision

No, they have more tpi. I'm not sure what the old one was or what brand it was as my Dad picked up the scroll saw at the scrapyard and so it was the blade that was in it.

The new one s finer though.

I've not tried it with different thicknesses yet. It didn't produce the ripple on all cuts though.
