… ….................................…-- Elevator Section Part 7 ---

============================================

I'm actually a lot further along on the elevator section that what it appears. The next three pages actually all happened before the side supports, the control panel and the start of the backdrop on the preceding pages. Sorry didn't get around to posting it.

.

Having the line straight above the lift point is important but not critical.

Think of the elevator working similar to a piston going up and down in a cylinder bore. It only has one item attaching it between the piston pin and the crank, the rod. The rod doesn't even stay perpendicular to the piston as the piston goes up and down. The pistons side walls and skirt keep it from rocking in the bore.

In the elevator's case the top track surface just goes along for the ride and the line to the top is similar to the rod on the bottom of the piston. The top is only a place to attach the line (similar to the piston pin) and a place to park the train for the ride to the upper level. The little wheels on the sides of the part of the elevator that goes up and down (shown above) are similar to the piston skirts that keep the piston from rocking in the cylinder bore.

The bottom fixed part of the elevator is the bore walls. Two of the walls are adjustable and can be pressed in until the moving part of the elevator is a fairly tight fit and won't rock going up and down. Also there are guided stops that will be shown shortly that also guide and stop the elevator at the top and the bottom of its stroke and level it out and position it. The line only has to raise and lower the elevator and is not responsible for centering or leveling it. I still want it as close to the center as possible though. Also if the line stretches a little over time that doesn't effect anything as the lift bucket never hits the floor so always maintains tension on the line.

One other item is the weight of the part that goes up and down. It is about 45 lbs.. I could lighten it but want the weight as that is a stabilizing factor and also now the weight of a 10 foot long N scale train is negligible so I don't have to deal with it being also centered.

Hope this helps and ( HERE ) is a video I put together earlier.
