I bought two Oddvald trestles as I was inspired by the piano stand hack but both would have been overkill for my little keyboard. I then worked out this way to use a single trestle as the keyboard stand base.
It took 3 or 4 hours though I did it over a few days to let paint and glue dry. The cost is £10 for the ODDVALD trestle and £7 for table top wood. I owned everything else already.
Large board for table top – 40cm x 90cm – I used 18mm spruce ply
Drill, jigsaw, hand saw, file, sandpaper
6 x 4cm wood screws
Instructions ODDVALD for keyboard stand
1. Draw out three brackets on the 40cm x 30cm ply using the measurements on the template or print out the A4 template to trace/mark them. If you print make sure the measurements are correct on the printed template.
2. Use a jigsaw to cut out the shape. Remember, the inside of the A shape needs to be a very tight fit on the sides of the top bar of the Oddvald so cut the wood slightly too large and use a square file to reduce it to size. Check often until brackets just about slide on while pulling the A shape open slightly.
3. Drill holes in brackets. The holes need to be around 50mm from the end of each bracket and counter sunk. The screws you have need to go from the counter sink through into the table top but not out the other side of the board so place your holes accordingly. I used 40mm wood screws.
Get the right height
4. You need to lower the table height so your keyboard keys is at the standard 72cm-ish hight.
Use calipers or ruler and pencil to mark 60mm from the bottom around the end of each leg. As the legs are at an angle you need to mark around the entire leg.
Use a hand saw to cut each leg down to size. Use a file to take the edges of each leg.
5. You need to move the long crossbar back so it’s out of the way of your feet while you are sitting at the keyboard.
Take both short crossbars and mark 50mm in the centre of the wood from one end. Then use a 6mm wood drill bit to make hole.
6. Use black paint to paint all three brackets, the bottom of each leg if needed, and the inside of the holes left in the short cross bars.
7. Watch paint dry.
8. Slide the brackets onto top bar of ODDVALD bar, one in the centre and one around 30mm in from each end. Be careful not to cover the leg holes.
9. Lay the 40cm x 90cm table top on a solid surface and place the top bar with the brackets in the centre. Clamp or use heavy objects to hold brackets in place. Use a 2mm wood drill bit to drill guide holes in the table top.
10. Remove the brackets and top bar, glue the top of the brackets and place back on the table top. Clamp again. Screw in place. Let wood glue dry.
11. Attach ODDVALD legs. Then attach the short cross bars. Then use the 6mm holes you drilled earlier to attach the long crossbar.
