[CAUT] Piano truck for six legs

[McNeilTom at aol.com]

Hi, Bob, and Colleagues -
 
You could use a regular Colson stage dolly with custom-made replacements  for 
the square leg sockets.  Probably easiest and cheapest would be to get  some 
steel channel from your local steel supply house or from a welder or steel  
fabrication shop.  "C 3 x 4.1" is the smallest standard size; that's 3  inches 
wide and 4.1 lbs. per foot.  Flanges are about 1 3/8 inches and web  thickness 
is about 3/16".  Have the shop cut three pieces long enough to  hold a pair of 
the piano's 'feet' and weld end pieces on the channels to keep  the pair of 
legs captured.  Have the shop drill and countersink a hole same  as in the 
original square leg sockets.
 
Using six of the tricycle casters might not be so good.  Unless the  floor is 
everywhere flat they will be forever rattling.  And they don't  provide 
anywhere near the protection to the legs afforded by the stage  dolly.

Sorry Bob, I didn't get this answered the first time. I did  
one for a church once. They wanted something as cheap as 
possible,  naturally, and didn't much care how it looked, so I 
did the cheapest,  quickest addition I thought of at the time. 
Salvage yard steel box, about  2"x3", about 14 gage or so (not 
very heavy). I hole sawed holes in the  ends for the legs to 
set in, and one in the middle for access to the  attach bolt 
and drilled a hole in the bottom the size of the bolt. With  
the legs in the holes (on bolts to keep them off the side of 
the hole)  the sides of the box came 2" up the leg, but the 
height of the piano  wasn't raised over what a conventional 
install would have given them.  Looked a little different, but 
it worked fine. I didn't cap the ends, for  cost savings.

One approach.
