for tersangka utama:
karena tersangka di atas berharga mayan mahal klo udah rakitan pabrik alias build up, logikanya masyarakat yang blom pernah tahu hasil keuntungan dari produk kerajinan kayu scroll saw bila di pasarkan, maka di berikan opsi membuat sendiri mesin scroll saw alias hand made lagi / DIY (Do It Your Self)

for handmade:
kelebihan mesin scroll saw handmade adalah segi ekonomisnya, misal harga mesin scroll saw buildup hampir 2jt an (yang bisa di pasang mata plain end) dan berukuran 22in besarnya, handmade harga ga lebih dari 1jt cost nya. dengan kegunaan hampir menyamai.
untuk mesin scroll saw build up, di bedakan dari sbb :
- kemampuan menghandel besarnya media kayu potong (16in , 20in , 22in, dll)
- kemampuan untuk menghandel jenis ujung mata gergaji (plain end & pin end)

1. Standard Tooth Blades
The teeth are all the same size and distance apart on standard tooth blades. There are two major kinds: wood blades and metal blades. The wood blades have larger teeth and more space between the teeth. They are designed to clear the sawdust as you cut. The metal blades have much smaller teeth and less space between teeth. I find these a bit noisy.
2. Skip-tooth Blades
These blades are similar to the standard tooth blades, but every other tooth is missing. The space (gullet) between teeth is much wider and keeps the blade cooler. Personally, I like these for most work. They are especially good for beginning scrollers.
3. Double-tooth Blades
This blade is a skip-tooth blade with a large space between sets of two teeth. These blades cut slightly slower but leave a very smooth cut.
4. Reverse Skip-tooth Blades
This blade is exactly like the regular skip- tooth blade, except the last few bottom teeth point upward. This is great for preventing tear- out or splintering on the bottom of the cut and for use with plywood.
When using a reverse skip-tooth blade you must set the blade in the clamps so that only two or three teeth are pointing up above the table top when the saw arm is in its highest position. You may have to trim a little from the bottom of the blade to accomplish this.
5. Precision-ground Blades
These blades are actually a skip-tooth blade with small teeth that have been ground to shape rather than simply filed. These blades are much sharper, cut in a straight line and leave a very smooth surface. Personally, I find they are great blades but very aggressive and unforgiving. I do not recommend them for the beginner.
6. Spiral Blades
These blades are simply a group of blades twisted together so there are teeth all the way around. You can cut in all directions without turning the wood. There are a few applications for this kind of blade, but they leave a very rough, wide surface, cannot make a tight or sharp corner and have a tendency to stretch as you use them. I do not recommend these blades except for special applications.
7. Crown-tooth Blades
This is a totally new design in scroll saw blades. The teeth are shaped like a crown with a space between each crown. The nice part is that the blade can be put in either way, so there is no upside down with these blades. I find they cut a little slower than a regular blade, but they are good for cutting plastic or Plexiglas�.
When the blade dulls you can reverse ends and have a sharp blade again.
saat membeli scroll saw blade akan di hadapkan standar" ukuran sbb :
Wide x Thickness - TPI (Teeth Per Inch) - Long
Lebar x Tebaal - Jumlah gigi tiap inch nya - Panjang
e.g : 0,026in x 0,011in - 28TPI - 5in
artinya : Lebar 0,026 inch x Tebal 0,011 inch - 28 gigi tiap inch - Panjang 5 inch
