So I did not have a case for my Ibanez RG350 and decided to make one of MDF.
The plan was that it would be cheaper than buying one but it ended at about the same price of an Ibanez case. It was fun to make though.
Step 1: Drawing
I made a drawing in SketchUp.
I realized afterwards that I should have made it a bit wider. Perhaps 20mm to make room for more styrofoam around the body of the guitar.
Step 2: Material
Precut (by the wood shop) 12mm MDF, styrofoam and four hinges.
Step 3: Preparations
I routed all outer edges but the corners need som extra filing, my son here to help.
Step 4: Construction
The boards have been glued and screwed together.
Step 5: Hardware
I bought some hardware. Corners, lock and handle: 237 SEK.
Step 6: Draping
The box and lid has been draped with some woofer fabric I had from other projects. I used wood glue (PVA).
Step 7: Mounting the Hardware
The hardware has been mounted, I screwed a piece of strap to stop the lid from falling over.
Step 8: Protective Inside
The styrofoam is cut with a knife and a soldering iron and is glued with wood glue (PVA).
Step 9: Draping Inside
This is where I'm almost breaking my budget. Cloth 100 SEK and spray glue 300 SEK.
Not a perfect fit but it works.
Step 10: Result
And this is the result, the guitar fits snugly. The case is a bit on the heavy side. But I think it could take some punishment.
The total was 1137 SEK but I had some of the stuff lying around.
