[DIY] My "Loud" Inner-ALC Experiment (Sugar Maple + Hinoki) - "Taiko"

Before I made the all-wood violin blade I posted earlier, I was actually experimenting with Inner-Carbon. This is one of an inner carbon blade, with carbon layers are bonded by epoxy while other layers hide glue.

The Experiment:

I tried a different wood combo than the usual Limba/Ash:

Outer: Sugar Maple (Tangential cut). I sanded this super thin (0.2mm) after the press to try and keep the wood feel.

Force Layer: 1.0mm Horizontal Hinoki.

Core: 2.6mm Ayous + Blue ALC.

The Result (Serendipity & Mistakes):

It feels fast with a turbo. Vibrates at around 1330hz

The sound was a total surprise. It is LOUD. It makes a huge "POK" sound, almost like a drum. I am guessing the thin maple act as a drum skin while the soft horizontal thick hinoki is acting like the drum body resonating the sound. It’s actually really satisfying to hit with.

I guess the feeling of fastness has something to do with the huge loud "pok" sound.

Play-wise, it has a weirdly high arc. I thought the Hard Maple would make it flat, but I guess because I sanded it down to 0.2mm, it flexes more than I expected.

(I laser cut a Tomoe representing Taiko, a japanese drum in the back after I found out it plays this loud)

The not so great (Weight):

The performance is there, but I messed up the lamination.

I didn't measure the epoxy ratio strictly enough, and the blade came out at 103.3g.

A member here (@SlowPower) gave me some great advice recently about measuring the epoxy by weight rather than volume, so I’m hoping my next attempt (maybe using Basalt fiber?) will land in the 90-95g range.

Right now it's at 196g with kts platz on forehand and ak47 red on backhand. It forces me to play with all my body. It Plays great, but I think it could be lighter?

Does anyone know of ultra-lightweight offensive rubbers that's on the cheap/ultra cheap side that you recommend?

did you glue everything in one lot or did you first make the ALC into sheets ?
there are not many layers here, I just glue it in one go and leave it on a tight clamp for about 50+ hours. Dry for 2 days before cutting to shape. but for more layered one I glue them in 2 go.
