[HELP] Akiyuki Elevator GBC

Elevator GBC (HELP)

Downloaded the pdf instructions by Blakbird and I am currently building the top part of this module with XL motor and change over unit to incorporate it into my next planned smaller GBC version of this module.

On page 77 - step 9 a shock grey absorber is used.

I only have Yellow version which seems very hard to compress and requires a lot of force to rotate the shaft with crank & wedge pulleys.

Presumable this gives the snap action to the change over unit.

Can anyone explain the difference between grey and yellow shocks.

Am I correct in using a plain 2L connector in the driving ring instead of using the ribbed type ?

Thanks in advance for any help.

The 6.5L shocks come in three different variations with different springs. The yellow are the hardest springs and will not work in the elevator module. They are much too stiff. The gray shocks use a softer spring.

No, it needs to be the ribbed type as shown in the instructions. A smooth type will not work. Because the shift mechanism is oriented vertically, a smooth type would not hold the driving ring up.

Blakbird,

Many thanks for the advice and the excellent instructions.

Wiil buy a grey shock with soft spring.

Re Driving ring.

On page 80 step 17 the part shown appears to be a plain 2L axle connector and the driving ring stays up OK but I will change anyway.

Finally got c/o to work OK after I found I had missed putting the two stops in place either side of the Red lever at step 20.

Thanks again.

Hmm, you are right it does appear to be a smooth connector in the instructions. If that works for you, then by all means use it.

I can confirm that the combination of grey shock and smooth axle connector is the way to go for this module.

Courbet,

Thanks for the timely advice, saved me stripping down work done so far on the c/o unit.

Grey shock absorber arriving next week.

Grey shock absorber received and the change over and drive units built as per Blakbird instructions.

Took a while to get c/o to work correctly but eventually got it figured out.

As the unit is quite large it was too big for what I required, so I set out to replicate the change over and dwell functions in a smaller unit.

Change over device uses a grey shock absorber but a much smaller trip lever snap over unit.

The 56Z turntable replace by a 28Z small turntable with shorter arms to give the same dwell action to the elevator cord driving wheel.

The whole unit is built within three stacked 5L x 7L frames for a very rigid structure.

Frame 1: Change over lever unit.

Frame 2: Reversing unit with clutch gears

Frame 3; Output gear unit giving up to four outputs.

Drive: M motor driving reversing unit via a worm / 24T gear.

Next step is to build an elevator tower and the ball moving cage.

The images below show the construction.
