Thanks Dale and Karsten! I'm really happy that you're both keen to get started!!! So without further ado....
1. INSTALLING A GUIDE RAIL[/u]
This is possibly THE most important part of the mechanism. If this is installed correctly, the rotor will have nowhere else to go but up and down. To do this, i firstly used ball-bearing type kitchen drawer runners, though these proved to be problematic when mounted vertically. I found that the ball bearings kept falling to the bottom, and the rotor would jam half way on its way up.
*The best thing to use for this is a sliding door track and wheel system that you can buy cheaply from a hardware store.*
I then mounted this on 20mm x 20mm box shaped aluminium tube. See the following illustration to see what I mean...
I installed 3 of these as any less than this could cause the rotor to wobble, and we don't want that to happen!
In this photo, you can see the track with the wheels interlocking it.
Here are some answers to some questions that you all may have...
How long were the Aluminum tubes and how did you attach the sliding door rails to them? The rails had holes pre-drilled in them, so I just used a good-sized bolt to fasten it to the tube. The tubes were 1100mm in length, though this may vary for your build.
How did you fasten them to the floor in the base of your console? I cut a square-shaped hole at the base level of the console, and poked the tube through. Be careful not to make to square cut too tight as when the tube flexes slightly with the movement of the rotor, it may make a creeking noise. Mine did that, and I had to make the hole larger. You can fasten the tube to the base any way you like.
OK...Here goes...first in a series of steps to motorising your time rotor!
First of all, you need: - an old washing machine motor - a reduction worm drive gear box. Unfortunately, I don't know what ratio mine is! - a door closer arm, pinch one from one of the doors at your work place, noone will notice - a drive belt - a frame to house all of this stuff!
here is the motor I use, it's only tiny really - out of a twin-tub washing machine. It is a single speed induction motor.
This is the reduction gear box
This image shows the side of the gearbox taken off, you can see the worm gear at the top
This is the door closing arm that I use
Here it is attached to the gear-box.
Next, fit the motor to the wooden enclosure. Underneath is good, as it reduces its footprint in the base of the console, and it raises the gearbox to a good height for the rotor to sit at stationary level
That's it for now!! Going away for a couple of days. Will be back on Thursday, so stay tuned!!! ;D
