Paul,

Have you contacted Yamaha about this issue? They might be helpful.

Thanks Brad,

Unfortunately, I studied this idea and this won't be the answer either.  There would be no way for the second strap to grab anything on the far end of the piano as it's really a near triangular shaped thing with two strait sides on each end 2' wide at the keyboard end. When I build this thing tomorrow and Tuesday, I'll get yall a picture of it.  This is a very strange shaped PSO.....not really the other digital short grands we've all seen in the past..like your nice image.

What I'm wondering is why Yamaha didn't think of this already, as they must have known some institutions would be wanting these units as well.

I guess I should patent whatever I come up with and retire <G>.

Thanks for your guesstimate on what might be done.

Best,
Paul

Agreed, construction may be the solution.

Another idea ( easier construction job ) would be to add a pair of 2x4 "feet" to your skid board....one at each at about 6inches from the ends of the board.

They become anchor points for straps that can apply opposing force as you tie down the piano.

I've made skidboards with these type of "feet" installed.  Also done a couple where they are removable, using counter sunk machine bolts and T nuts flush mounted to the surface of the skidboard, ( under the covering of the skidboard )

The placement of these feet help position the dolly in the same place each time.

I attached a screen shot of this setup made in Google Sketchup.

I think the wedge will have to be constructed.  Even if I put downwards,(towards the far end of the piano) there would still only be two feet and a little bit on the board with a different angle and no 90 degree place to put any strap on it.  Perhaps I should design and patent it and make some bucks!??!!

I'm also wondering why Yamaha didn't think of this when designing it.  I realize this piano wasn't really designed for institutional use, but perhaps it should have been thought out better.  I certainly wouldn't put it on a moving board and into a truck to go to our East Campus without some sort of better support. It would certainly have dire consequences.  I sure wish I could have seen them uncrate it at the Yamaha store when it arrived! It didn't even come with a bench! :>(

Best,
Paul
