Dave,I am using 1 1/4 x 0.120 4130. I bought the ready made axle from Aircraftspruce. Looks about the right size too.CheersPeter.-----Original Message-----

Dear List, I ordered my axle (for a wood gear - spoke wheel set up). I ordered 1 1/8X .083 Chromoly Tubing from Wag-Aero. Never having ordered Chromoly Tubing beforeI wasn't sure what to expect. It has arrived and it looks and feels justtoo light and flimsy to serve as an axle. So, did I screw up, or is this thesame material that most builders are using?

Dave,The Flying and glider plans call out 1 1/4 X 12 GA. Chrome-Molybdenum for theaxle. 12 GA. is .1045" thick, I think most guys go up to .120" rather than downto .095".1 1/8 X .083" does sound a little light and flimsy.Mine is split axle and I chose 1 1/4 X .120".Skip I ordered my axle (for a wood gear - spoke wheel set up).

I used 1 1/8" x .100 and was not happy with the amount of bow in the axle. I switchedit to a 1 1/4" x .120Dick N. ----- Original Message -----

Clif, Your right. F&g 1 1/2 X 12 GA. The 1934 plans split axle 1 1/2 X 10 GA. (.130")My landing gear is a combination of 1934 plans, Grega, and Wag Aero Sport trainer,because I wanted wider tread than Piets 56". Wag Aero has the 1 1/4 X .120".Skip, reading better with morning light and stronger glasses.All the plans I've got specify 1 1/2" tubing.That's the 1932 Fly+Glide Piet, 1933 F+GScout split axle and my plans from DonPietenpol.Where's this reference to 1 1/4"? My copiescame from EAA 10 years ago. Did theymake a change somewhere along the line?Clif________________________________________________________________________________

.120 is the correct size if you're going brakeless. The axle length will be extended if you install brakes which may require upsizing or heat treating for added strength.Greg C. ----- Original Message -----
