Tweaking suspension on Michell Orbe


Hello,

To all the Michell table users out there - how did you go about tuning your suspension for the perfect "bounce"? What is the "goal" of the suspension tuning and how do you tell when you have it just right?

The instruction manual for the table recommends to set the springs so there are ~2mm of distance between the fabric pads at the bottom of the springs and the bottom of the metal subchassis. I've approximated this - but there is a decent amount of side to side motion in my bounce.

Any Michell tuning experts around?

Thanks in advance

Has2be - Thank you for sharing your knowledge!

I do admit that I'm a bit confused though... :-/

The instructions in the link you provided say this:

"By rotating the springs anti-clockwise (rotate the rubber grommets while holding the metal knurled tops), centralize the three spring support studs in their holes in the chassis (as seen from above). A correct setup of the suspension has been achieved when a light tap on the turntable's spindle results in a free and even vertical bounce for a number of seconds."

Is the rubber grommet (and the "bushing" you refer to in your post) talking about the black piece right below the knurled top of the tower?

So - is the above part in quotes suggesting that rotating the spring (while holding the top of the tower stationary) will affect whether or not the tower is centered in the opening on the chassis?

Does centering the tower coincide with the notion that you are suggesting of having the end of the spring pointing towards the center of the bearing? Or are these conflicting ideas?

Sorry for the confusion - just trying to make sense of it all! Right now I have a side to side bounce going on that I'd like to eliminate.

It would be nice if the manual mentioned any of this...
