Raising or Lowering your bike
This information is already in the WIKI —> HERE under Dogbones I will remove this section at 12:30am duplicate content:!: ~Wiki Editor
To raise the tail about 1.5“-2” I go with a 5“ center on center. Stock length is 5.8” center on center. 1mm shorter bones will yield about 2.4mm raise on average.
I've always made mine out of 6061 T6 because it's inexpensive and strong enough.
If your buddy can get it, go with 7075 T6. It's about 3 times as much but has almost double the strength rating. 2024 has about a 7k lb higher rating than 6061 but isn't as easy to come by and doesn't weld very well. Not that there will be welding of dogbones but….
Make them .25“ thick and then standard dimensions after that.
The below figures should give people an idea of the strength ratings of aircraft grade aluminum. Keep in mind any of these aluminums need to be a T6 for strength. A 6061 0 will not be anywhere near as strong as a 6061 T6. All data can be found at http://www.matweb.com
2024 T6 - Shear Strength - 41,000psi Fatigue Strength - 18,000psi Machinability - 70% Yield Tensile Strength - 50,000psi
6061 T6 - Shear Strength - 30,000psi Fatigue Strength - 14,000psi Machinability - 50% Yield Tensile Strength - 40,000psi
7075 T6 - Shear Strength - 48,000psi Fatigue Strength - 23,000psi Machinability - 70% Yield Tensile Strength - 73,000psi
