Having a lot of trouble making the new platform upgrade

Post by cambazz » Sat Jun 23, 2012 3:05 pm

Hello Uppers,

I finally got the new platform suit, but I am having a lot of trouble installing it:

From up site the picture I understand the spring has to be put between the platform holder, and the bottom part:

And here is a picture of my parts:

as you can see the spring hardly fits there. Also, I was just able to put the screw, no washers between the spring and the platform, or bottom piece.
I dont understand why the spring also? could not we put some washers on top of each to elevate the platform? the spring is really hard to fit in there?

Am i doing it correct? There was so little available documentation, i am not sure if i got everything right.

Best Regards,
C.B.

and also, how many mm's does the platform need to be raised? what if i dont use the provided springs and instead i put a specially made nut in place?

best.

Springs are really not the solution, they will quickly be crushed to solid height and no longer work as intended.
All the ideas that have been used, 3 wave washer, 3 rubber o-rings and now these springs are a bad solution in engineering terms for the hardware configuration. :geek:
You need a central point to pivot on and it needs to be a strong enough apposing force to keep the platform from rotating in the sloppy clearance holes in the sheet metal arm for the 3 M3 SHCS.

Get slightly longer screws and punch some rubber discs to create the central column that can be both the pivot point and the compressible compliant point, then always tighten those screws, you can add another disc if you get too close to the support arm.

This is the solution that truly works, try it and you will see.
