    When I decided to try a fEarful build as a quarantine project, I posted this thread sing advice about tools and stuff. Some requested build pics, and I figured I's start at new thread more aptly titled to document my process.

    How total noob am I? Maybe not absolute: I built a passable bass body in my college's wood shop decades ago, and haven't touched any wood working equipment since. I can solder patch cables and wire pickups with a reliable reference guide. My only power tool is a cordless drill/screw driver.

    Assessing my skill level, I chose to order a fEarful 12/6 flatpack kit (the wood) and a fEarful 12/6 deluxe kit (the rest). In general I went with the least pricey options, but I threw in the tweeter too.

    Model: fEarful 12/6/1

    cutout specifications:
    - D0604k (2 NL4 speakon medium size)
    - ASD1001 He70 Horn + Lpad
    - No handle cutout (will use a strap)
    price: USD $179.95
    plus s&h: $196.89

    Parts: fEARful 12/6 Deluxe Kit
    - Midrange: Alpha 6a
    - CBG 12/6 Mid Xover Option: Greenboy CBG, Parts only
    - CBG Tweeter Selection 12/6: ASD1001 He70 Horn xover Parts only + Lpad
    - Connector Dish Model: D0604k (2 NL4 speakon medium size)
    - handles: none
    - corner style: Small Pen Chevron
    - price:: USD $388.92
    - plus s&h : $404.00

    total investment: $ 600.89

    My hopeful goal is to mimic the "stormtrooper" look of white Mesa cabs:

    The kit arrived last Tuesday 5/12/20, a bit dinged up by UPS.

    Today, Saturday 5/16/20, I began the dry fit process. As a noob I had to look up Dry Fit. It means assembling without glue or fasteners: literally checking to make sure everything fits.

    First I laid out all the pieces in the garage:

    There were no written instructions ( thought the instructional video says there should be, ) so I watched the video and downloaded Greenboy's plans to try to make sense of which part was which. I had a samsung tablet with me to view the digital info.

    with no proper tools to my name, I found the nicely cut pieces made a fine straightedge.
    I started labeling the pieces in pencil as I Identified them. A few had some helpful markings already, but this wasn't spelled out like an Ikea project.

    Arrows indicated which way the edges go are also helpful, if only to verify things.
    The shelf support kept falling over, so I had the idea to use water soluble kindergarten glue to fix it temporarily in place. (Schools closed anyway, the kiddo won't miss it. ) Experienced observers might spot the seeds of my fist error in the image.

    Have fun! Take your time, use PL glue, plenty of clamps and everything will be fine... and sound good!

    first mistake discovered: Why is the port divider piece not flush with the front edge? It became clear as I first tried to dry fit the back piece. I had reversed the bottom and was facing the speaker baffle to the back!

    A quick tear-down and rebuild, this time making sure the 1/2" lip is in the back. 20200516_144709.jpg

    The speaker baffle was flipped! I discovered this when I tried fitting the mid range box. So one more partial tear-down and rebuild...

    And the midrange box now fits. With no biscuits for attaching the box to the outer panels, I had to leave it out of the rest of the dry fit. 20200516_150152.jpg

    fitting the back I discovered the worst of UPS's scuffing efforts. Some millimeter deep gouges on the interior side. Hopefully no long term acoustic effects. It will be foamed over eventually...

    inserting the back bracing ...the fit didn't make sense at first, until I saw how it was to vertically rest on the port divider. 20200516_152900.jpg

    Side braces installed. This leads to my next confusion...

    Interior shot of the left side pillar brace. Everything else fits so snugly, but there is this inch gap at the bottom of the pillar brace that made me wonder if I'm doing it right. Double checking the plans says yes, as designed...

    Now for a real problem: The bracing actually forces apart the back and sides. They seem too thick by a 16th or an 8th. Is this normal? It was a stormy day, the garage was humid, could that be the culprit?

    Check the biscuit slots for sawdust or debris. That would keep the panels from aligning properly.

    Yes. Keep in mind it is possible that while your pieces were being made whoever was running the biscuit cutter didn't plunge it all the way in, thus not cutting the slots deep enough. I have a Dewalt BC and it does require some effort to keep the fence hard up against the wood.

    A fix would be to just sand down or cut your biscuits a bit.
