If you used bolts like that, the plate could just have two holes and not need a slot since the bolts can be removed when you want to get the wheel off. We know roughly what kind of torque is on the axle so it should be easy enough to calculate what bolt size is needed.APL wrote: ↑Sep 19 2018 12:05pm
In the meantime.
What do you think of the double bolt idea? Grade 8 bolts would go down into the axel a ways,
for a good anchor, and the torque would work against shear strength, which is extremely high.
9mm or 10mm bolt shafts would fit a dropout.
Perhaps the dual bolts could go through a torque arm strap on the outside face of the dropout?
Hmm..just an idea
If the dropout has a slot like your drawing, the holes could just be above and below the slot so you don't even need a plate.
