(...) Then it's a lift lock 'cause that's what Jeff's going for--the bottom of the lock is suppose to look like water going up and down and work like a lock in the Welland Canal Lift Lock system. And then the doors are suppose to open and the boat's (...) (19 years ago, 5-May-05, to lugnet.technic)

(...) First off I think it should be called a boat lift rather than a lock, because in a lock only the water moves. (...) I've read the other posts in this thread and I like both the string and the rack idea's. Racks are commonplace on locks because (...) (19 years ago, 5-May-05, to lugnet.technic)

(...) So much for quick diagrams - of course the back corner should attach to the RIGHT side string not the left. ROSCO (19 years ago, 4-May-05, to lugnet.technic, FTX)

(...) In case I didn't explain myself well, see the diagram (click to enlarge): (URL) The yellow lock level is attached to the string at the red exxes. Pull A to raise, B to lower (they can be wound on pulleys). You can reduce it to 1 per side a la (...) (19 years ago, 4-May-05, to lugnet.technic, FTX)

(...) That looks like a *great* project - I hope you can make it sturdy and reliable! As Larry pointed out, you need to keep all the vertical worm gears in sync by tying them all together. Do you have room for the 24t - worm gear gear blocks in (...) (19 years ago, 4-May-05, to lugnet.technic)

(...) (snip) A worthy project! Hope to see it in person at NMRA... I suppose you already considered vertical racks at the 4 corners of the "water" that are embedded in the lock walls (the rack, visible, might look like a ladder or steps cut into the (...) (19 years ago, 4-May-05, to lugnet.technic)

(...) Another possibility is to not make the connection between the lift lines and the lifted frame rigid, but "slippable" (for instance, instead of using a single line, use a loop that attaches to the frame by wrapping around several fixed pulleys (...) (19 years ago, 4-May-05, to lugnet.technic)

(...) Nice work!! (...) I would suggest trying string. Just have a loop of string in each corner, coordinated like you do with the screws. Or you can run it as 1 big loop, that would avoid the problem of slippage causing tilting. But you would (...) (19 years ago, 4-May-05, to lugnet.technic)

For our current train layout I have attempted to create a working lift lock. Attempt 1: The lift lock project started about a year ago. My first designs used a scissor type construction ( XXXXX ) To try to raise the water, but there was not (...) (19 years ago, 4-May-05, to lugnet.technic, lugnet.org.ca.rtltoronto)
