Winter 2019 Build Off - The Carl Factor

I wasn't going to participate this year, I just had a long mental block about what to mash up. I spent days looking at pictures of every bass you can imagine and couldn't come up with anything. I threw in the towel, then was prodded/shamed by the nice folks here on LC to think about it one more time.

The second time, instead of looking at random pictures I thought about basses that I've lusted over. I came up with two, the first one I can't explain - the Kubiki Factor bass. I just remember seeing this in a magazine at one point and thinking it was the coolest bass I had ever seen. So that's part number 1, this is especially apropos because I'm now a headless convert (I'm doing a five string so I won't be replicating that detune thing on the headstock):

The second one is probably pretty easy to understand. The first thing I did after I got home from seeing Primus the first time was to figure out what bass he was playing, such a cool instrument, never mind how he plays it. So the second is Carl Thompson. I think the "twins" are some of the best examples of Carl's work, so I'll use that as the second half of this build:

Here's the raw mash up, and it's pretty raw!

From there I derived an outline in powerpoint (luddite I know):
Slide2 (1).jpg


The details of the bass:
  • Neck through five string headless/fretless with side fret lines
  • 35" scale
  • Honeybadger 5 string pickups
  • Audere preamp
  • Brazilian bridge/tuner set up (never used this one before)
  • 7 piece laminate neck (maple/walnut)
  • Fingerboard will likely be tiger maple with a wenge binding, coated with UV resin
  • Heavily carved body will be a hippy sandwich of walnut/anigre/walnut with wenge strips in the body
  • wood covers over the pickups
  • chambered body
Somewhere in my cluttered computer filing system and/or workshop I have written details about how the body will come together, but as is true with all my builds, I'll be making a certain amount of this up as I go.

I've got another build in the final stages, I'll probably glue up the neck blank today, but the rest of it will probably not really get rolling until after Xmas.

In the wood pile below from the bottom up I've got wenge, anigre, walnut boards with the dimensioned neck wood on top. I've never built with anigre before, it's got some awesome grain and figuring on it, I'll find some cool sections so it shows through the carving. It's got a nice warm brownish coloring that should look good against walnut. Overall I'm looking for a bass with very muted colors, but lots going on with all the carving. I saw some awesome reviews of the Honeybadger pickups, but I haven't ever heard them live, they are very heavy, if that means anything. So the sound is a bit of an unknown factor at this point. I got them used, but they appear to be pretty new.

While I was waiting for the dye to dry on the other bass I pulled the neck blank out to work on it. I figured everything out the other day, but now that I had a good picture I figured I'd check it out again. I always check measurements like this many times before making them. It turned out to prove to be a good practice again as I found an error, whew. I just subtracted the top thickness from the wrong number. It wouldn't have been catastrophic but it would me a slight redesign on the neck construction.

I'll check it again in the morning before making the cut, but I think I've got it right now. That knot will be largely removed and what remains will be buried in the body.

I cut another piece of anigre off, this one is much cleaner. Then I cut out the chambers and control cavity, then glued it up to the walnut that will be on the back. I used sheetrock screws to hold the pieces in the correct orientation then put them in the the vacuum bag to clamp them together. I left a little overhang on the neck side, so once they're dry I'll cut that off to get a clean gluing surface. There will be a piece of tiger maple between the wings and the neck.

Super busy morning in the shop today. As I've said before my wife makes cutting boards, she's not quite independent in the shop, so when we are down there together I am often stopping what I'm doing to help her with a cut or to check something she's doing. It's great to spend time together like that so I don't mind at all, in fact I enjoy it, but today solo in the shop I see that there are times where I need time without distractions.

I pulled the flat snake and my wings out of the bag, they look good, one small gap that I'll be able to make disappear pretty easily (it will likely end up on the shop floor anyway). I made a fresh cut on the neck side to get a good glue surface. Then I made the chambers and control cavity deeper, the back is thick, so I could take some of that away.

I'll go over my dad's now and cut the cover out on his pinless scroll saw. Mine has pins in the blades, so I'd have to drill a large hole to get that through the wood.

Then I started working on the neck. I got the sides and back cut. I had a bit of an oops with the new palm router when the adjusting nut bottomed out on the guide board. I'm not sure how I will fix that right now. I'll look at it later when things are further along, nothing I can do about it now.

I bought some wenge to act as an accent on the back of the neck. Yesterday I went to the local Woodcraft to get some carving tools with my wife and they had a sale on padauk, so I bought some of that. The padauk will end up being a stripe on the bottom and the back of the neck. I'll also use it on the pickup covers and maybe up by the headpiece. I made a bit of a process error in that I should have glued these up before I cut the sides off the neck, I'll have to see what I can do to make a good glue surface. The accent woods are cut just a bit wider than the neck. I can either use my hand plane or risk sending it through the table saw, we'll see.
