Default Switching From Spiral To Flat Reverse Blades

I have been using spiral blades for several years now.

I received some Flying Dutchman flat reverse toothed blades yesterday.

I now have to teach myself a whole new way of scrolling. I had no idea it would be so hard.

I had a few scraps of wood strips to practice on. I scrolled out some "welcome" letters for a future sign. The edges are much cleaner with the reverse tooth, I didn't have to clean up any feathering. YEEEHAAAA!!!!

The letters measure 1/2" x 3/4". Figured to start off small with a higher difficulty level, then it will be easier when I scroll a larger area. I know this first attempt isn't perfect but I will get better in time. I didn't do any clean up with this piece.

This morning I ordered some reverse spirals in case I get too frustrated turning and turning my work. I don't have to turn the whole piece with spirals.

I need to do some more scrolling today to gain more experience with the strait flat blades.

Did anyone else have a hard time switching over?

Thanks for viewing.

Karen

Karen, many of us scrollers find spiral blades much too difficult to work with. FD blades are just about the best though, aren't they?

Hi Steve,

I'm getting used to using the FD RV blades. I'm liking them more and more. The clean crisp edge is fantastic and will save me clean up time.

Have a good day.

Hi Karen
As Steve said, most scrollers learn on flat blades, and find it quite difficult to work with spirals. With a spiral blade one has to have a very steady hand, as the slightest wavering will register in the cut, whereas the flat blade has a tendency to stay within the cut line (like the keel on a ship). If you can work successfully with a spiral, you will do wonders with a flat blade, once you get used to turning the work, (and countering the tendency of the blade to cut more aggressively on one side)
I have been using FD's for the last 8 years - they're certainly the best.

Once you get used to the turning with the flat blades, things will go much easier. Personally I have a hard time controlling spiral blades for precision work. I do like them for veining in some areas where you need better definition. I just switched to FD blades, now I am wondering what took me so long. They are simply the best out there. Take your time and things will progress nicely for you.

I want to thank everyone for the very helpful tips and encouragement.

Funny, I find the spirals much easier with turns, corners, and intricate patterns. BUT, there is sanding involved afterwards for a crisp inside edge. I tighten the tension on the spiral and it stays within the cut area. If it wanders, I tighten it up a little.

With the flat blades, I am still having a problem keeping the blade in position when turning the piece. When there is a large cut without many turns or corners, I will use the flat.

I find myself switching back and forth between spiral and flat blades depending on the cut. Takes more time, but less frustration for me.

My Delta is a real pain in the butt when switch blades.

I will keep with it, and perhaps I will find a happy medium when scrolling. I am hoping to sell enough items this season to get a newer model scroll saw.
