You're right. If we were talking just shear strength. I believe the original KR retracts only used 1/4" bolts for the axles on the main gear. My tailwheel is a single fork tailwheel and I'm concerned that, supported on one end only, the 1/4" bolt/axle will bend, not shear. Normal loads would probably not be a problem but when it hits that break in the cement at 30 miles per hour ! My present tailwheel has an axle in the 3/8" to 7/16" range and is rated for (I'm guessing here) about 250 pound load. Larry Flesner
