It's not tacky. It says says 38-40º on the package. About 10€ a sheet on aliexpress.

You might want to try the Palio AK47 Blue. Not really that tensor feel but close enough.

MDP, did you manage to make a balsa blade, without carbon, in the Off-/Off range, that plays like an all wood?

Yes you are right, feedback is very important. But at the moment i'm looking to build blades for myself. When i find i can build what i imagine, then i can build blades to others. I'm not totally happy with this blade but actually a club mate wanted to buy it on the spot, i guess everyone has...

It's getting better. It takes patience to get the details right but it pays out in the end.

Had a chance to try the blade last night with two Bluefires. The results are positive but i have mixed feelings. After playing i would rate it a solid Off-. The blade is on the heavy side but feels balanced, the handle is comfortable but has room for improvement. The cons: Not suited for...

The core is 2mm, Kiri 1.2mm and top 0.6mm. Yeah, i had to use a thick medial to balance the core. I will play with the blade tonight and report tomorrow.

Thanks, i'm getting better. Bamboo is very heavy, i was lucky this one was a little lighter so i decided to make a core, but i think it will work better as a medial ply to enlarge the sweetspot.

New blade. This one is: Mahogany / Kiri / Bamboo / Kiri / Mahogany - 5.6mm - 90g sealed. I'm expecting All+/Off-.

That was made in excel but i'm using google sheets. Right now it's not ready to share but when it's completed i will share a link to google sheets with all the data. I will upload the image again with a larger font. Here's the table if you want to plot your own chart 5.6 50...

Now in a more user friendly version. This is an example for a 5.6 mm blade. You input the weight without handles (about 20g), the frequency and see where it falls on the chart.

You have to the table i have posted. For example, a blade with e=5.2mm, 60g and F=1300Hz would be off+. A blade with e=6.2mm, 60g and F=1300Hz would be All. Blade 1 would be very difficult to manufacture. It has a density of 0,5 g/cm3 and a stiffness of 7000 MPa, there's no way that could be...

Yes, they ship worldwide but you have to add the products to your cart to calculate the cost.

Thanks GinjaNinja, i saw that store but the shipping cost to Portugal would be 45£, that's very high! I got my Kiri from Spain, http://www.tormodel.com/index.php they list it as Paulownia. I got my order the next day and only 7€ for shipping. There is also a store in Aliexpress that sells in...

Balsa cores are a little tricky because the stiffness/weight ratio is high and the mass is low. Right now i'm only analyzing 5 ply all wood blades, and getting good results, but if i introduce composites then the problem gets more complex. Also, there are stiffer glues then others, and sometimes...

Ok, forget the frequency. Frequency is just the way i have to find the Young Modulus of the existing blades. Without knowing their composition all i have left it's the measured frequency, thickness and mass. With that i can calculate the approximate stiffness of the homogenized section based on...

Funny, i found kiri in 1, 1.5, 2.0, 2.5, 3, 4 and 5 mm easily and cheap but haven't found Ayous. I also bought WRC but only in 3.5 and 4 mm which is a little much for my needs. I have to get it to the right thickness but i don't have access to a thickness sander or planer. I was thinking of...

That is commom sense and i have already explained a few times along the topic: Stiffer=higher bounce=faster

How do you guy deal with the different thickness for the plies? Do you source the material in the dimensions you want or do you use a thickness sander or other tools?

Thanks Tropical. Yes, i saw that thread, in fact it's what gave me the idea to try my own analysis. For those who doubt, or don't understand, that there is a correlation between the bounce test, frequency and blade speed i suggest a couple of papers...
