this one cheaper and is proper stainless steel that has tensile strength of 450+MPa. which is 35+lbs. http://www.amazon.com/Beadalon-Round-Stainless-Steel-15-Meter/dp/B002QYW70Y and only $5. ordered. video is a given.
You're gonna string with steel wire?! The grommets ain't gonna take it! . Also make sure you don't hurt your forearm and wrist. IMHO resistance training (eg with racket cover on) is better than weight for developing the speed and power that is critical in badminton.
well, we will see. no way in hell is that steel wire getting anywhere near my Victor and Yonex. but i do have other rackets lying around. i might have a good candidate for this experiment. grommets are cheap anyway. as for training racket, at the moment this has digressed into steel wire badminton. i will go back to training racket once i finish playing with this.
I wonder what effect the steel wire will have on the shuttle, I bet you will damage alot of corks! Good luck with your adventure!

ok, so here is the weight calculation. given that a string is approx 9m long when strung on the racket. density of stainless steel is 8g/cm3 we have 22 gauge string which is 0.00065m thick. the volume of the 9m string is then: 0.000325^2 * pi * 9m = 2.986cm3 which comes to approx 24 grams. looking ok on the weight side. wrap some more near the shaft so it won't be so super headheavy will do.
ok. looking at more stainless steel property. the yield strength for the 316L stainless steel is too low. and for a 22awg wire it will start plastic deform at 12.6lbs i have changed the order to 21awg wires which have a slightly better yield strength and will plastic deform at 16lbs. which is still not too good.
Interesting, yet scary. I think you might have to fine something to strengthen the shaft. Maybe use some lead tape and cross hatch it to make sure that the shaft can take the new head weight? Maybe along the grip too. dont need to go crazy, just make sure that the shaft wont crack after 2 hits.
You have to get braided wires for hanging picture frames. Those are flexible yet have high tensile strength. http://www.framingsupplies.com/HangingWire.htm
i don't think i will ever fit 2x 1mm thick string through a grommet... besides. i am more worried about the yield strength at this point. i don't want the whole string bed going soft after hitting with it.
Here's a goofy idea. 1. Take off the end cap from the handle. If there is any of the filler stuff (technical term is "gunk") inside the handle, remove and put aside. 2. If the end of the shaft is visible, check to see if it is clear of any obstruction. If obstruction exists, clear said obstruction. Use drill with 1/8" titanium bit if required. Gently. 3. Keep racquet handle pointed up at the sky and head down to earth. 4. Take a really thin funnel. Bag of fine sand. Put thin end of funnel to shaft opening. Pour sand down funnel. Allow sand to filter through past grommets by constantly shaking and jiggling. Fill as desired. Remove funnel. Cap off shaft. How to cap off shaft? Use your imagination, don't ask me! 5. Replace gunk from Point 1 above into handle. Replace end cap. Pray. If the T-joint interferes with the process of filling in the frame, remove a grommet and use the hole as an insert point with one of those funnel-type implements you might find on a dentist's table. Replace grommet when done. Repeat prayer.
