    Lockdown 1 x 12 Pine Cabinet

    Apologies in advance for the long post...

    Well, with lockdown in SE QLD extended until Sunday, I'll get a good jump on this project.
    The last of my parts arrived today, so the timing couldn't be better.

    My motivation for this is to cut down some weight from my existing 1 x 12 that's made out of chipboard and MDF. That weighs in at 14kg. I know it's not that heavy, but I ain't gettin' any younger...

    Based on weighing my parts & pieces and whacky calculations, I estimate the whole thing should come in around 9.29kg (loaded). I'm including that very specific number here so I can reference it when I'm done and see how close I was!

    So here's a pic of my rough unassembled pieces, and I will elaborate on my scheme below:

    The 4 panels that will form the main speaker box are actually a unassembled beehive "super" (or brood box?). They come pre-cut with dovetail joints and two ends rebated (which will be the front). I wish I could take credit for the idea, but I pinched it from a guy on YT!
    I'm not properly tooled up to cut dovetail joints and I probably lack the patience tbh, so this was a perfect option for me.

    The box is made from 20mm solid NZ Pine (whatever that is) and is pretty clear. There are some small knots on one end piece, but I'm fine with that. I'm going for a fairly "rustic" look, so I won't be putting tolex or any covering on, and will stain and poly.

    I'm using 12mm premium ply (BGS) for my baffle board and 7mm premium ply for my back panel(s).
    Some of the timber I already had and some hardware (jack, jack plate, feet and a 12" Celestion).
    The cab will end up costing me about $180+ which is half the price I've seen for unloaded manufactured cabinets.

    This cabinet is to be paired with my Quilter Superblock US which is a brilliant little analogue 25w amp the size of a dual overdrive pedal.

    I'll post more pics as things progress. Thanks for indulging me!

    Thanks Andy.
    It's the Oxblood/Tan from Evatco.

    At this stage I’m envisioning a diluted Golden Teak for the pine.
    I think that grill cloth will suit that nicely.

    Yeah, I didn't mention the YouTuber by name because I have issues with the "guns" part of channel. I'll leave that there...

    Did you tolex yours, or is it painted? I can't tell in the photos.

    That's a fair enough call!

    I used a cheaper marine leather type stuff. I think from Clark rubber by memory.

    I've managed to get a fair bit done. Still pretty rough and I have few corrections to make, but all in all, going pretty well.

    Day 1 was just gluing up and squaring the box, and I also cut out the baffle board. I have yet to cut the speaker hole (that's on tomorrow's agenda). The speaker box is within <1mm of square, so I'm happy with that. There is an annoying gap on the bottom front right corner that I didn't notice when I did the dry fit... bugger! I can fix it and it will be mostly hidden by the metal corner later.

    Day 2 has been cutting and mounting the battens for fixing the baffle board and back panels, as well as cutting the back panels themselves. I think I'll need to redo the top back panel as I cut it a bit too narrow for my liking. It's purely an aesthetic issue.
    This what happens when you cut it "near perfect" the first time, then try and get it to "perfect" - D'oh!!!

    Tomorrow is cutting the speaker hole in the baffle board; doing the round-over routing; some minor filling and then lots and lots of sanding. I may revisit the larger back panel, but I'm out of 7mm ply and loathe the idea of spending more money! Plus we're in a pretty strict lockdown, so it may have to wait anyway.
