Spirals

Aarghhhhh! I need a beer!

Ian, I was pretty surprised when I went back to the board and saw the title of your message, and here's why.

I spent a couple hours in the shop this afternoon trying out spirals, I had tried them before but never cut anything with them except some letters and practice lines. Today I actually cut something, with them. I wanted to know what all the hype was about so I gave them an honest try. What I decided is
1) They are very aggresive and you must have absolute control over your piece of wood. I was cutting 3/4" pine and the blade went through it very easy.
2) They will move in any direction you want, and it was more like tracing the line then cutting it. You sorta steer the wood as opposed to turning it.
3) The kerf is very wide, compared to a straight blade.
4) They create a tremendous amount of dust, much more then a straight blade.
5) I might try them again but I doubt they'll become my regular blade.
Here's a couple pics of my first attempt,

Marsha;
You did very well for your first try at using spirals. It is generally easy to see if a finished piece was cut with spirals or with a flat blade and this is one of those cases. . Did you find yourself wanting to spin the wood occasionally even though you were using a spiral. ? ? That happens to me whenever I try them and I have to correct myself and move the wood in all directions instead of spinning it around with my finger tips.
Your findings on them about wide kerf and tremendous amount of sawdust are right on with what most die hard flat blade users report not to mention the roughness of the cut on the edges compared to the smooth edge that flat blades produce.
Sounds like you will be joining the majority of scrollers that uses spirals just when you need to when the size of the piece is too large to spin within the throat of your saw.

Marsha you did very good for your first time. I love spirals and soon you will be able to even shave those little fuzzies off with your blade. Just rember that spirals do have a direction to insert them - sticky side goes down when you run youur finger along the blade. and I am not sure but that is what looks like is why you have the fuzzies ( maybe the blade was inverted) I really do hope you continue to use spirals and it will open up a whole new avenue to scrolling for you.

Looks like you got smoother cuts with your spirals than I did, Marsha. What size blade were you using?

I was cursing the spirals when I managed to chop out a piece that was meant to stay after forgettting momentarily that spirals cut all ways .. duh! If you look at the pic you can probably see what's missing ...

I do kind of like the effect the spirals gave on the piece I cut though... it's the first time I've used spirals other than for a couple of bits of veining once before...

Other than the straight edges on the feather section and the shape of the wood itself this was all cut with a #5 spiral ... maybe a smaller one would have been better ...

Yo're right abot the dust for sure ... I was covered in cedar sawdust when I'd finished!! Think wood-coloured snowman

Wood is just over 1/2 inch thick red cedar ... the piece is about 14 inches high. Perhaps harder and thicker wood might make the spirals easier to control?

The best way I've found to control spirals is to use FLAT blades

Before I get blasted, I'll explain...... I'll use spirals if I'm cutting a pattern with "spots" as they remove a bunch of wood fast. For all the other rare times I use spirals, I almost ALWAYS run a flat blade down the pattern line first. Then, if the "vein" would look better "wider", I'll run a spiral down the flat blade cut. piece of cake to control it that way.......

That's an interesting way of doing it BF - I'll give that a try next time ..

My first try using spirals was almost a disaster! No only did I lack adequate control but installing the blade gave me a fit. When I would tighten the blade down, it would bend the end of the blade making it impossible to thread into a gate hole. It I tried to straighten it out, the tip would break off. I may try them again but what it the trick to installing the blade.

Mike, that is about the same experience that I had with spirals. After fiddleing around for awhile I got one to stay in the holders. I used them to cut letters out of a board that was too long to turn around in my saw. It turned out all right for what it was used for.

I can't seem to get on with spirals, so i do like BF does.
