Given your goal of moving the digital piano pedal panel backward to accommodate longer legs, and your preference for an adjustable and aesthetically pleasing solution, let's explore your proposed idea and some alternatives, along with specific Bunnings recommendations.
First, let's look at your plan:
Your Proposed Plan: Extending with Metal Brackets
Your idea of using additional metal brackets to extend the pedal panel backward is sound. It's a direct approach to gaining the desired legroom.
Pros:
-
Direct Solution: Directly addresses the problem of pedal proximity.
-
Relatively Simple: The concept is straightforward to implement.
-
Customizable: You can choose the exact extension length.
Challenges to Consider:
-
Stability: Ensuring the new brackets provide sufficient rigidity for the pedal unit, especially during use. You don't want the pedal unit to wobble.
-
Load Bearing: The pedal unit, while not extremely heavy, will still exert some force. The new brackets need to be strong enough.
-
Aesthetics: Finding black brackets and bolts that integrate well with the existing stand's appearance.
-
Adjustability: Achieving adjustability might require more complex bracket designs or a rail system.
Alternative Solutions (and why they might be less ideal for this specific case):
-
Modifying the Bench: While you didn't ask about this, sometimes a different bench height or depth can help. However, this doesn't directly address the pedal position relative to the stand.
-
Professional Fabrication: Having custom brackets fabricated would be ideal for strength and aesthetics, but it's significantly more expensive and time-consuming than a DIY solution from Bunnings.
-
Extending the Pedal Cables/Wires: This is an option if you were to completely detach the pedal unit, but it's not what you're asking for, and would likely result in an unstable pedal unit.
Detailed Plan & Bunnings Recommendations:
Given your preference for adjustability and a clean look, I suggest a combination of slotted angle brackets or slotted channel for adjustability, along with strong L-brackets.
Option 1: Slotted Angle or Slotted Channel (for adjustability)
This option gives you the adjustability you desire.
Parts to buy from Bunnings:
-
Slotted Angle or Slotted Channel (Black if available, or paintable):
-
Description: These are metal strips with a series of pre-drilled slots or holes, typically used for shelving or framing. The slots allow for variable bolt positions, providing adjustability. Look for a robust gauge that won't flex easily.
-
Why: The slots will be key to your "adjustable" requirement. You can bolt the existing pedal bracket to different points along the slotted angle to fine-tune the depth.
-
Examples: Look for "slotted angle steel" or "slotted channel" in the hardware or shelving section. Often, they come in galvanised steel, which you could paint black with a good quality metal spray paint (e.g., Rust-Oleum or Dulux Metalshield).
-
Quantity: You'll need two pieces, one for each side of the stand, long enough to extend from the existing attachment point backward by your desired distance, plus some overlap for mounting to the stand.
-
Heavy Duty L-Brackets (Black or Paintable):
-
Description: You'll need strong L-brackets to attach the slotted angle/channel to the existing stand structure. Choose a size that provides good surface area for attachment.
-
Why: These will provide the primary structural connection between your new extension and the stand.
-
Examples: Look in the brackets section. Search for "heavy duty angle bracket" or "corner brace."
-
Hex Head Bolts, Nuts, and Washers (Black or Paintable):
-
Description: You'll need various sizes.
-
To attach the new L-brackets to the stand.
-
To attach the slotted angle/channel to the L-brackets.
-
To attach the existing pedal bracket to the slotted angle/channel.
-
Why: Strong fasteners are crucial for stability. Use washers under both the bolt head and the nut to distribute the load and prevent damage to the material. Consider using Nyloc nuts (nylon insert lock nuts) or thread locker (Loctite) to prevent loosening from vibrations.
-
Examples: Look for "M6," "M8" or similar metric bolts. Measure the diameter of the holes in your existing pedal bracket and the slotted angle to ensure compatibility. If you can't find black bolts, you can paint them.
-
Metal Drill Bits:
-
Description: If you need to drill new holes in the stand or the new brackets (e.g., to match existing stand holes or to secure the L-brackets).
-
Why: Essential for a clean installation.
-
Metal Spray Paint (Black, e.g., Rust-Oleum or Dulux Metalshield):
Installation Steps (General):
-
Measure: Carefully measure how far back you want the pedal unit to go. Also, measure the existing bolt spacing on the pedal bracket (~6cm as you mentioned).
-
Disassemble: Carefully remove the pedal panel from the stand.
-
Mount L-Brackets: Attach the heavy-duty L-brackets to the inside of the piano stand's side panels, where the existing pedal unit attached, but positioned to allow for your backward extension. Ensure they are level and secure. Use appropriate bolts, nuts, and washers. You might need to drill new holes in the stand's side panels if existing ones don't align.
-
Attach Slotted Angle/Channel: Bolt your chosen slotted angle or channel to the L-brackets. The angle should extend backward. This is where you'll utilize the slots for future adjustability.
-
Mount Pedal Panel: Attach the existing pedal bracket to the slots in your new slotted angle/channel. Use bolts, nuts, and washers. This is where you can make small adjustments to the depth of the pedal panel.
-
Test and Refine: Reassemble the pedal unit and test the position. Make small adjustments to the pedal panel's depth using the slots in the angle/channel until you find the ideal position.
-
Paint (Optional but Recommended): Once you're satisfied with the position and everything is secure, disassemble the new brackets and paint them black. Let them dry thoroughly before reassembling.
Option 2: Heavy Duty Flat Bar and L-Brackets (Less Adjustable, but simpler)
If adjustability is less critical than pure strength and simplicity, this option is viable. You would essentially create a fixed extension.
Parts to buy from Bunnings:
-
Heavy Duty Flat Steel Bar (Black or Paintable):
-
Description: A solid flat bar of steel.
-
Why: This will be the direct extension. You'll drill new holes in it to match the existing pedal bracket holes and your stand's mounting points.
-
Examples: Look for "flat bar steel" in various widths and thicknesses. Choose something substantial.
-
Heavy Duty L-Brackets (Black or Paintable):
-
Hex Head Bolts, Nuts, and Washers (Black or Paintable):
-
Metal Drill Bits:
-
Metal Spray Paint (Black):
Installation Steps (General):
-
Measure and Mark: Measure how far back you want the pedal unit to go. Mark the drilling points on the flat steel bar to match the existing pedal bracket holes and the mounting points on the stand.
-
Drill: Carefully drill the marked holes in the flat steel bar.
-
Mount L-Brackets: Attach the heavy-duty L-brackets to the inside of the piano stand's side panels.
-
Attach Flat Bar: Bolt the drilled flat steel bar to the L-brackets, extending backward.
-
Mount Pedal Panel: Attach the existing pedal bracket to the drilled holes in the flat steel bar.
-
Test and Paint: Test the position and stability. Disassemble and paint if desired, then reassemble.
Important Considerations for Both Options:
-
Tools: You'll likely need a drill, drill bits (for metal), a wrench/spanner set, a measuring tape, a marker, and potentially clamps to hold pieces while drilling.
-
Safety: Wear safety glasses when drilling.
-
Measure Twice, Cut/Drill Once: Precision in your measurements will save you headaches.
-
Test Fit: Before making any permanent modifications or painting, dry-fit all the components to ensure they align and function as intended.
-
Cable Management: Consider how the existing power/signal cable for the pedal unit will be routed with the new position. You might need to use cable ties to keep it tidy.
-
Aesthetics: If you can't find pre-blackened parts, a good quality metal spray paint designed for outdoor use will provide a durable and aesthetically pleasing finish. Remember to prime the metal first for best adhesion.
I lean towards Option 1 (Slotted Angle/Channel) because it directly addresses your desire for adjustability, which will be valuable in finding that "ideal position" for your long legs. Good luck with your modification!
