Default The weld

The picture of the step weld doesn’t show any ripples in weld seam this may indicate grinding of weld . This will weaken the weld possibly leading to weld failure. The steps I received had visible weld ripples. Thank you Pat Cullen

You had better call Vans about your specifics. The only thing people are reading is "step" and not which bird it is for. I know there are a few failures at the lower weld on the 10 and Vans is evaluating a fix for it. It is not a weld issue and the tubes crack 90 deg to the weld due to tube cross section shape deformation under stepping loads.

I assumed given this thread is in the RV-10 subforum, it would go without saying the topic relates the step for the RV-10.

But I'll ask the reps at the Van's booth at Sun 'n Fun for clarification. Thanks.
