    I suffer from a low grade variant of OCD - SKOCD Sorta Kinda Obsessive, you know... I like matching cabs and now that the cherry walnut 1x12 is finished -

    I need to have a matching head that is 20" wide. I had a single ended amp that I built a cherry shell for but it's only 12" wide and nothing I own or am willing to own fits in it. The Barracuda chassis is 18.375" wide and it really likes EVM12Ls so I'll pull it from the African mahogany & zebra wood cab it's in for this build -

    So measuring about in the shop tonight I came up with a plan. Here's the wood for the project -

    I'll decide which of the walnut bits will be used for the trim. Cutting and squaring should begin this weekend.

    Cutting has commenced, three cherry and eight walnut trim pieces and pine for the bottom.

    This cherry is 'happy' namely it doesn't have any warp / cupping that makes finger joints 'unhappy'. I've done some nutty things with finger joints including plans to build a drum cylinder with my drummer son but boobs became more interesting than drums and that project died a flaccid death.

    The trim is cut.

    On to the finger joints on the cherry.

    That is some nice looking cabinets!
    If I had gear that looked like that, my wife would allow me to move into the civilized part of the house.

    Thank you! I've been told by wives at the shows I've displayed at that the cabs were living room worthy...

    Finger joints being cut

    [​IMG]

    A new bit of equipment, a phenolic insert [I've had it for 3 years] I finally installed for use. It certainly keeps the saw dust down.

    [​IMG]

    Glue up commences. I've said it a million times - if you know a wood worker buy them CLAMPS! These planks are only 5.75" wide but I've managed to stuff a bunch of clamps on it.

    Coffee time.

    One of the joys of wood working vs. metal is if you screw the pooch on measuring and thus cutting you can glue in more wood. I cut the bottom bit of pine a 1/16" too narrow. Luckily I had a bunch of 1/8" walnut strips I used for piping on a 1959 head shell and now a FUBAR is an artful accent.

    [​IMG]

    The other challenge of the day is the top cherry piece that laid so nice and flat for the finger jointing decided it needed to stress relieve with a bit of a twist. :facepalm: So I clamped it flat to the fab table and glued in the pine bottom hoping that the additional bit will straighten or at least minimize the twist.

    [​IMG]

    Meanwhile as I impatiently wait for a reasonable hour to commence cutting on the face plate and more contemplation of my mad scheme to rout in the beautiful flowing script of the Satellite logo...

    Gibson even made [probably just refinished them] a few cherry burst upright pianos.

    Face plate time.

    Cutout corner locations

    [​IMG]

    Drill it!

    [​IMG]

    Cut to it.

    [​IMG]

    Then the cut that makes me [and my fingers] nervous.

    [​IMG]

    The angle that starts the round over.

    [​IMG]

    The moment when you know your box is square...

    [​IMG]

    Gluing of the walnut trim pieces has started - no pics as of yet and now to draw the Satellite logo and begin carving it in.

    The trim and the fake fingers are glued in - sanding time tomorrow night!

    [​IMG]

    [​IMG]

    Then in the great 'Let's push this to the hairy edge of insanity' mode I decided to carve the Satellite logo into the face plate. I didn't like the metal logo plate covering up the wood. I also enlarged it 2X.

    [​IMG]

    Two + hours of carving with a mini plunge router and a 1/32" router bit.

    [​IMG]

    I had to finally walk away as I was tired and starting to fix the cuts I didn't like. Yep, done for the night.

    Took a break yesterday and now back at it in the two hour window I give myself for shop noise after work.

    Sanded the 'proud' trim bits and fingers flat with 60 grit then smooth sanded with 80 grit.

    [​IMG]

    Trim and finger details

    [​IMG]

    Now on to the face plate. I fixed a few of the letters since the last pic as the proportions weren't quite correct for SKO standards. I consulted with my color expert with some test dyes and RIT cherry was the winner.

    Painted in and the over laps sanded off

    [​IMG]

    Filled with epoxy

    [​IMG]

    Tomorrow evening will commence the corner round overs. After that the entire cab will get sanded out to 220, tea washed, 0000 steelwooled then hit with clear.

    Round over time. I draw 3/8" & 3/4" witness lines to cut the 45° first bevel to the 3/8" lines. I used 60 grit disks on the end grain and my favorite #3 high angle hand plane to cut the walnut on the front of the cab.

    [​IMG]

    I finish out the the plane cut with 80 grit and then sand a series of flats to the opposite side. Then I take the orbital sander and literally round the flats from one of the sides to the other.

    [​IMG]

    Then a quick lick of 150 grit on the rounds then it's super glue and accelerant time to fit the small gaps on some of the fingers and where the trim joins. I also filled the pin holes in the logo.

    Tomorrow night finish sand and tea wash.

    My very first (real) job was a cabinet maker position which led to a shop foreman role until it closed down. I joined the military shortly afterwards. I sure miss the woodworking craft. It felt natural to me.

    After - still wet

    Tomorrow night three coats of clear - then wait 72 !!@*#!!! hours to final sand then more clear then more waiting...

    I really enjoy watching you build cabinets. Amazing work and I'm always excited to see the finished product.

    First coat of clear, I'll stuff another couple in the next 1.5 hours.

    While the cherry is better looking on the speaker cab the walnut is nice on the head.

    Test fit whilst I impatiently wait for the finish sand and last few coats of clear. I'll drill the handle, feet and chassis holes as well.

    [​IMG]

    [​IMG]

    Test fit - could't go any narrower!

    [​IMG]


    I expected the walnut to lighter on the head cab the cherry is significantly lighter. I suspect I'll be leaving the head shell out in the sun for a few days / weeks.
