Dampening bar for wiper motors

[Thread]

With SCN5, the pro Simxp****** uses a dampening bar, attached with rubber.
It smoothes the feeling, more real, they say.
I am constructing my rig with wipers, and made one dampening bar too, but i am wondering if it is needed at all for wipers, i am afraid there will be no vibration simulation as with SCN5.
And i will want all the possible fast movements.
Now i have to decide whether to include it, because of the fixed geometry by welding.

Anyway, why are the wipers always slower, if they got the same electrical power as SCN5?

Now i see that the damper bar is for:
Dampening Bar (Prevents simulator jumping and movement)
It can be a problem with wipers as well, but if it happens, can't it be solved by putting rubber under the whole frame?
[I can not continue welding, until i have not decided ]

I think it can be done with rubber under frame, you'll just need to aprox. calculate how much your frame can weight with you on it, so you could find adequate strenght of anti-vibration rubber.
