SHOCK ABSORBERS. x7520 x7425

With reference to the broken shock absorber casing. I find that the casing I was going to send you off the bump is not the latest type. The case which Hancock has broken on 22-EX is the very latest type F.80321. Apparently, from Hancock's report, it has fractured in the usual place.

Would therebe any objection to thickening up the casting at this point? It seems very strong from the drawing, but as we are in production, I suppose we ought not to risk leaving it as it is.

The cross steering tube fouls the bottom of the damper just on maximum bump braking. The axle twists the rear end of the spring up in spite of the torque control. Perhaps this has some bearing on the trouble.
