Building an Organ Dollie

So I have this 250 pound organ sitting in my already somewhat cluttered garage. I was thinking it would be great to be able to move it around myself if needed; also it would be easier to work on if it was raised up a bit higher off the concrete floor. I decided to build what I'll call a platform dollie to put the M3 on - a bit of 2x4 lumber framing, with a 3/4" plywood deck and 4 locking casters at each corner. Here's the completed dollie:


It's 48 inches long by 29 inches wide, just big enough to comfortably hold the M3. Materials were (2) 2x4x8's and a couple 2ft by 4ft "handy panels" from the home store, 3/4" thick, sanded on one side. A few 3 inch drywall screws for the framing, and some 1.5 inch screws for the decking hold it all together. On the bottom I mounted (4) 2 inch lockable casters. For the frame, I cut one of the 8-foot 2x4's in half for the sides, then cut (3) 26-inch pieces from the other 8-footer for the ends and a brace in the middle.

Here's a picture of the organ on the dollie:


The only thing I think I might have done differently was to use larger casters, like 3-inch or maybe even 4-inch, which would make it even easier to roll around. Note the toothbrush in the picture - starting to work on the amplifier. There's quite an accumulation of dust and "stuff" on it and all around the wiring, so I was starting to clean that up.
