Re: Walk thru module



I understand your idea but there is only about 1/2" or thin plywood that overlaps between the pieces.  There is nothing strong enough on the lift section to hold the bolt.  My second idea adds more overlapping material that can then secure the catch whether bolt/pin or angle iron.

I think 2 bolts attached to lift section dropped into 2 holes drilled in fixed section is sufficient to keep bridge from separating.  bolts could be one eighth to quarter inch diameter.

I have another idea for the latch mechanism.  WE add an angle iron to the top of the small fixed end unit.  Then a new board on top of the lift up section that has a notch in it to hook on the angle iron.  One on each side will fit in the same line as the hinge support boards.  this would still rely on gravity to hold it down.

Another very simple approach would be to take off the slide latches and replace them with one latch that would not only hold the bridge down from kids lifting it but also draw the sides together.  The latches on the facias are the type I am suggesting.  They reach out and then draw the parts together.  It would need to be opened and closed with each entry but under your watchful eye, it could be released while waiting for a train to pass so you can get it up and down quickly before the next train comes.  We can look at this on the work day Feb. 8.  I have the latches to consider.
 
There are other options being discussed as well.  So bring your ideas.

I think the way to keep the walk thru module from spreading apart is to run strap from the modules on each side under the floor of the walk thru module.  We could use one of the tie down straps and chinch it up lightly to keep the modules from spreading apart.  It would be an easy thing to try at the next show.
