Pare sa se foloseasca foarte putin la fabricarea lemnelor de paleta.

Limba wood makes a good table tennis blade. The usage of limba wood became popular in 1950 in guitars. It is considered as as a west African wood. The limba wood even replaced wood like mahogany because of its straight grain and dark color.

Blade spec: Made from Mahogany solid wood.
Speed: All/All+ (I bounce the ball on the bare wood)
Thickness: ~5.6-5.9mm
Weight: 90g (I bought a precision scale this time)
Handle: Straight (The handle I traced based on Xiom Stradivarius)
Finish: Heavily sealed then lacquer finished.
Play Review: Rubber combo used: Neo TG2 on FH and Dipper 3 on BH
Speed: Range from All to OFF. The speed is not linear. On passive/short/block, the ball bounced very short. I have put many of my short serves into the net. On my opening loops, many went off the table. Mid/Far from table, the ball flew fast like a rocket. Control is tough because this non-linear behavior.
Oh well....enough fun with making blades....what should be my next experiments? Boosting? Tuning? LOL

Physical Properties: Moderately heavy and hard with medium bending and crushing strength, low stiffness and shock resistance, moderate decay resistance, and good stability in use.

Hai ca ti le dau pe toate
Sa stii ca si la Hinoki am remarcat neliniaritatea pomenita mai sus. Mingile scurte merg foarte incet, iar cand trag mi-o trimite ca din tun.

I’ll be using common names and a few bits of technical data to frame these species. The technical references made will include a rating on the Janka Hardness Scale, the specific gravity, and weight per cubic foot of each wood.
The Janka rating is determined by measuring the force required to embed an 11.28 mm (0.444 in) steel ball into wood to half its diameter (thus leaving an indention of 100mm sq). I’ll keep it consistent by using pound-force readings.
The specific gravity of a wood is its relative density to water.
And the pounds per cubic foot is (as the phrase implies) the weight of a cubic foot of the wood measured in pounds.
Anigre (Yellow)
Anigre Yellow wood for table tennis blades
Janka: 740
SG: .40
PCF: 30-34
This African hardwood is suitable for medial and top plies, it has a nice soft/woody feel and a very smooth texture. Good for DEF+ to OFF- depending on the other plies its used with.
Ash (White)
Ash White wood for table tennis blades
Janka: 1320
SG: .66
PCF: 42
This is a wood best suited for fast all-wood blades. Its heavy and hard so its best paired with lighter and softer core and outer plies. It's rarely used and when it is, it's generally a medial ply.
Balsa
Balsa wood for table tennis blades
Janka: 88
SG: .17
PCF: 11
Balsa is one of the most diverse woods used in blade making. Due to its durability its only practical use is as a core (or handle for ultralight blades). Its density can vary significantly and its behavior is relative to its thickness, thus it can be used for any range of speed.
Basswood
Basswood for table tennis blades
Janka: 410
SG: .41
PCF: 27
This wood is well suited to blade making. Its in that ambiguous range of hardness and density which can be used for any ply. Its generally used in cheaper blades but it can certainly make a quality product. Its behavior is widely determined by the plies and thus it is another very diverse wood.
Cedar (Red Western)
Red Western Cedar wood for table tennis blades
Janka: 350
SG: .37
PCF: 23
This wood is a good substitute for cypress. It has a soft woody feel and a very nice grain pattern when quarter sawn. Its a perfect candidate for single ply-blades. Kevin from American Hinoki deserves some credit for popularizing this wood in table tennis blades.
Cedar (Port Orford)
Cedar Port Orford wood for table tennis blades
Janka: 720
SG: .44
PCF: 30
A bit harder and denser than its previously mentioned cousin, this wood is also a good candidate for a single ply, as well as a lovely substitute for Hinoki Cypress.
Cypress
Cypress wood for table tennis blades
Janka: 300-800 (depending on species)
SG: .20-.46
PCF: 32
There are several different species of cypress and they’re all usable for making blades. The Chamaecyparis obtusa, or Hinoki wood (as we call it) is perhaps the most sought after wood for blades. Unfortunately its just about impossible to get hinoki here in the United States, so I guess us woodworkers will have to settle for POC. Cypress is very much like cedar in its feel and appearance, but it tends to be more yellow. Cypress and the two cedars mentioned can serve as cores, medial plies, and outer plies.
Douglas Fir
Douglas Fir wood for table tennis blades
Janka: 650
SG: .50
PCF: 34
I haven’t seen any other blades made with Fir, but its one of my favorite woods for medial plies. Its very much like the last three woods mentioned.
Jatoba
Jatoba wood for table tennis blades
Janka: 2820
SG: .71
PCF: 56
This wood is very hard and very heavy. Its only practical use is as a very thin top ply. It melds well with balsa to create a long pips-friendly blade.
Kiri
Kiri wood for table tennis blades
Janka: 250
SG: .26
PCF: 16
This wood is from the Paulownia family. Its a bit over double the hardness of balsa, but it remains very light-weight. This is a great core wood for faster blades with heavier medial and outer plies. Just like balsa, it cuts down on vibration and makes a blade with a little less feeling than something made with a wood like cypress.
Koto
Koto wood for table tennis blades
Janka: 950
SG: .65
PCF: 35
This wood is widely used by Butterfly. Its a good offensive wood. It tends to feel pretty hard and has a sharp tone.
Limba
Limba wood for table tennis blades
Janka: 490
SG: .45
PCF: 34
Limba is a great wood for outer and medial plies. Its has a medium-soft feel.
Obeche (Ayous or Abachi)
Ayous wood for table tennis blades
Janka: 430
SG: .38
PCF: 24
This wood is in 90% or more of all blades on the market. Its commonly called Ayous or Abachi. Its used as outer, medial, and core plies, as well as for some single-ply blades. It feels like limba.
Poplar
Poplar wood for table tennis blades
Janka: 430
SG: .42
PCF: 30
This wood is good is similar to ayous and basswood.
Spruce
Spruce wood for table tennis blades
Janka: 300-500
SG: .43
PCF: 27
This wood is generally used as a medial ply. Its similar to cypress and the cedars in terms of its feel.
Walnut (Black)
Black Walnut wood for table tennis blades
Janka: 1010
SG: .59
PCF: 40
This one is mostly used as a top ply, but I have seen it used as a medial ply. It has a hard but crisp feeling.
Willow
Willow wood for table tennis blades
Janka: 360
SG: .39
PCF: 26
This is an awesome defensive wood. It eats up the force of an incoming ball. It has a hollow feeling.
Zebrano
Zebrano wood for table tennis blades
Janka: 1575
SG: .74
PCF: 46
Another hard and heavy wood. It has a surprisingly good woody feel. Its not used by any major manufacturers but I’ve seen other custom shops use it. Its definitely an outer ply only.[COLOR="Silver"]
Dl. Dan Pop (0448-352369) face lemne la comanda . Presupun ca ai gasi un meserias bun si aproape de casa. Ti-ar putea face un lemn cu proprietati diferite pe cele 2 fete.
Pt iarba as fi curios sa incerc lemn Jatoba (vezi mai jos), dar nu cred sa-l gasesti la artizanii locali.
Jatoba wood for table tennis blades
Janka: 2820
SG: .71
PCF: 56
This wood is very hard and very heavy. Its only practical use is as a very thin top ply. It melds well with balsa to create a long pips-friendly blade.
Am constatat si citit ca suprafetele dure merg foarte bine cu iarba. Cu cat sunt mai dure cu atat mai mare e spin reversalul.

Atentie, nu e mahagony ci mahogany
