Re: tilt seat - was Re: (ET) It's here

Hm. Well, it seems that when it is just beyond vertical, there is a lot of
stress on a rather small point in the plate.

Ah well. I think I'll fix it and install some sort of lift rod. Kind of 
like
on a car hood.

> No strap.  No chain.  It stops when you are out of travel, just BEYOND
vertical.  If you have a tiller on the back, the lift stops the seat.  The
E10M, E8M had a stamped/formed lid that's even heavier, same story.
