I should avoid going into the shop late in the evening....
A half hour ago, I ran the Y axis ram of my 1964 FP2 into the back of the vise, with some combination of the rapid and an 80mm/min feed. I had expected that in this situation the feed shear-pin would break and protect things, but it didn't.
The damage seems limited, but the L-bracket attached to the rear end of the Y-axis lead-screw is no longer 90 degrees :angry:. I'll have to pull off the ram to fix it properly. The Y lead-screw is no longer straight, but I'm pretty sure that's because of stress from the bent bracket, and the lead screw will spring straight again when I remove it.
When I got the machine, this same bracket was bent and I needed to bring it back to square and shim it. Now it looks like I'll have to do that again.
The shear-pin in my machine is an original Deckel part. Should it have snapped and prevented this damage?
