When there is no tetra on it, there is no friction at all. Its when we start picking up tetras that causes problem. We put teflon strips in the channels between the different sections of ladder and then put wheels that would line the sections to where there would be no movement cept up and down. Tell ya what....this saved us alot of time.

Actaully, we used pollyethelene. The strips were too big for all the sections but one so i had to spend some serious time with a kerosine parth cleaner bin!

Some bracketry combined with a grooved ball bearing fixed the issue for the carriage. We are prolly going to make another set of that for the first ladder cuz it likes to bind a bit.

Its a good bot though!
