Building the uber-J. Part Eleven.

Bits and pieces. a few things happened while I was absent from this blog and I've got quite a lot to cover so, here it goes....

Headstock ferrules - On the left is the one I made. On the right the one I bought. They are very similar. Only, the one I made is 1.5mm thinner and slightly smaller in diameter. Which works better since ferrule and anchor's size together must be smaller than the total HS thickness including about 4mm allowance for the screws.

I much prefer the look of brass to that of gold - it goes well with the brass nut too. BTW the nut will be slimmer and with less sharp angles than this - I'll do that when it's time to fix it to the neck.

I used this thing here to carve the ferrules. It's a cheep China-made drill press - which over here costs about $80. I can do most of what I need with it.

Everything else is pretty much done by hand. I hand sawed the part from the rod - thicker than I needed coz the cut was bound to be irregular.

On a block of scrape wood I drilled a cavity exactly the size I wanted the final brass part to be (thickness and diameter). With the rough brass sticking out of the cavity I shaved off the excess metal on both sides and end up with a flat, leveled top and bottom. That is crucial to drill straight through the center.

I drilled the hole first, then the beveled part - which was made with the bit you see in the picture. Finally with sandpaper and steel wool I shaved off tiny irregularities and sharp edges.

Once I figured out how to go about with it it took me about 20 min each. Maybe the next batch will take me less if I don't screw up too much

I made this t-rod cover in Macassar Ebony, trying to match the grain. Eventually I will route a shallow recess on the headstock for the cover to sit into.

I've drilled the headstock cavities. The ferrules are flush with the wood. Right now are only sitting there for picture purpose ;) I just luuuuuv it!

The little MOP inlay is a symbol I have used for years to sign off my emails.... O(=< ....... To me it looks like a bass. And it just so happens that my fellow musicians call me Mr. Bassman......yeah.....and this symbol does look like a man when you turn it 90ºCW.... so Bass- man. Perfect! :) ( some say it looks like a mairmaid......or in the position of the picture it reads Vivo...which is Italian for Alive......OK...enough meanings!

The name Uber-J will likely be engraved on the t-rod cover.

The elec. cavity is done. I must confess I'm not 100% pleased with it - never work when you're in a hurry.... well... it will be fine after some more routing and sanding.

I routed a jack recess to try and achieve a few goals. 1. jack doesn't stick out. 2. jack points upward to facilitate inserting cable behind strap 3. in case the cable is not secured to the strap it won't be disconnected accidentally. We'll see if that works pretty soon. ;)

I won't be able to spray until next week. So, this next few days I'll finish the cavity; cut the cover - brass or M Ebony.... mm...brass, I think; route the recess for the t-rod cover; insert the side dots....make the slot for the nut.

Before spraying I will assemble every part - p-ups and el. excluded - and string it to double check that everything is right.

I will also test a few positions for the strap locks, just to make sure the bass is both well balanced and the 22nd fret positioned where I like it - clear of the thumb, that is.

till next update ;)
