  1. Oh yes - here's a diagram I roughed out:

    trussrodrouting.jpg

    Basically, the yellow line indicates the trench sunk by the round nosed bit which extends to the ends of the collars. This needs to be snug to the rods, but not tight. The green line indicates the larger flute bit which you square off to house the collars. Again, snug so the rod doesn't rattle but loose enough to it doesn't seize. The white line indicates the "tunnel" from the headstock to the rod which the adjuster goes through. The red line show the "opening" of the headstock so the adjuster can be accessed without it being awkward to work with.

  2. I use a combination of round-nose bits and flute bits for truss rods cavities, since I primarily use dual action rods which don't need a curved trench. The round nose bits run the length of the rod from collar to collar leaving a nice rounded trench. The smaller flute opens up and squares the bottom of the ends for the collars - you can then neaten and square the recesses for the collars with chisels or a corner punch :-D You then drill into the headstock at 90° to create a hole for the adjuster to emerge, and then using the larger flute bit to extends the trench where it emerges over angled headstocks for access with adjustment tools. To a degree, a lot of these steps are unneccessary, but this is probably the furthest you'd want to take it for completeness. I didn't go that far with my current bass build - I just ran the round nose bit the entire length from the far collar, over the headstock and then opened up the trench at the headstock end for adjustment. The rod was installed with a couple of drops of silicone under the collars to stop em moving.

  3. I've been searching high and low for laminated black/green/black (green, not mint!) to make a custom pickguard. There are a few auctions on eBay for JEM pickguard and headplate sets in the right material, but I can't seem to find the source or a suitable replacement. The only other choice I have I guess is to make my own using 1mm plastic sheets and laminating it myself with acetone.

    Before I consider this option, has anyone got any leads?

    Many thanks in advance :-D It's going to a good cause (my T-Bird).

    EDIT: Agh, just noticed that the ideal material i'd prefer to laminate into the pickguard is solvent-resistant....

  4. Cool. Received ten bottles today as well as a set on inlays which i'm installing tonight. I'd say it's the equivalent of medium viscosity CA so it should fill the gaps in reasonably finished inlay cavities nicely given a good chemical curing period before sanding. Excellent product!

    PM sent, Setch.

  5. Totally on there Marksound :-D The analogy of an author applies also - whatever the name on the front of the book, the quality of the print or the paper it's printed onto, the content shines through. Better gear does help develop technique through the whole "feedback in learning from the sound" to a degree, but not as much as general study and practice of course.

  6. None of it is glued yet. Since it's a good ol' classic 2x4 neck, you can do EVERYTHING as far as the routing goes on the tenon without gluing the wings on! The neck is a lot easier to handle without the extra bulk of the wings, so whilst i'm still doing "coarse" work (routing, bandsawing, etc.) i'm leaving the wings off.

    As you can see, I have yet to complete the headstock (got a bit distracted yesterday as my wife and I went to a GWAR gig).

    Anyway. More about the build. The neck tenon is five laminations of wenge and mahogany, the central mahogany core being some OLD OLD growth quarterwawn mahogany which, with the wenge, should add a good deal of stability and stiffness to the neck:

    The wings are plain mahogany. After about three months of research, I couldn't figure out an easy or economical way of doing the Gibson-style V-jointing between the wings and the body so I sacked it off in favour of a straight planed edge join. The finish is going to be a solid one, most probably in black with green accenting same as my mainstay gigging bass. In that respect, I better do some hunting for black-green-black pickguard material or plastics which I can laminate to achieve the same effect....once the pickguard and truss rod covers are made, i'm hoping to have them engraved with the band logo or something along those lines....

    The nut is currently going to be a Warwick Just-A-Nut 2 which is a height adjustable plastic nut which is simple to install and will get the bass up and running in the shortest time possible. I'll most probably replace this with a black Corian nut - ring your local outlet for samples which are ideal for several nuts! :-D

    Oh man, I never mentioned how proud I was of my first well planned and executed scarf joint. The other two scarf joints were done in a bit of a hit and miss manner, but using Setch's great tutorial and a couple of similar tutorials on here, the laminations line up perfectly. Once i've shaped the volute i'll post pics and beam with self-satisfied pride of course!

    Overall, a very simple and quick build also. No more than six hours work has been spent so far (lots more in terms of thinking and planning time however) excepting the gluing time of course. I'm tempted to rattle off a few more Thunderbirds now!

  7. If a luthierie is releasing a video giving insight into their "tools of the trade", i'm sure that showing somebody hammering in frets looks a lot more old-school and "desirable" than a chimp whanging frets in using an arbor. Maybe i'm biased against marketing, knowing how it works to manipulate your perceptions. Anyway. I think that on the face of things, hammering in frets makes luthiers look experienced and confident which leaves an impression on your mind of attention to detail, care and consideration.

    Personally, I love the Taylor factory tour where they make no bones about CNC machines, automated spray booths and all the advanced manufacture procedures which improve potential error margins hugely, and make what used to be boutique craftsmanship down to earth. Of course, boutique craftsman make one-off creations, whereas manufacture is geared to quantity....

    I digress. I believe that pressing is as good as hammering, but this is dependant on who bears the hammer or the press. A badly slotted and prepped board will suck no matter how good the fretting. Whatever works for the luthier to achieve the same end result shouldn't matter unless you're severely suffering from obsessive-compulsive guitar manufacture disorder.
