obviously doing it 'from home' one would expect the exact consistency and rigidity that a commercial process would yield... as all things it would have that downside... with the upside being the potential for a more malleable application. if the rigidity was comparably 'close enough'.

hmm, well the search goes on then!!

well sir... I mean specifically... what is in your view the correct epoxy for this application? mikro mentioned that it would be a heat cured resin... is there such a think available to reg joes like myeslf?

tell me more of this.... "correct ep-oxy"

kind of makes me wonder... how much tension is on that carbon fiber when it is pulltruded? what if you took carbon fiber tow... cut a 3/32 grove on the back side of a neck... clamped it down and pulled it tight (just by hand) and then use reg epoxy to seal it in place? the carbon fiber they use on fishing rods - they don't put any tension on that... they just roll it up around a rod. then again, maybe that fabric already has epoxy and has tension... seems pretty limp in the video. yet they heat it up... and all of the sudden it's hard. and another thing... how well does carbon fiber/epoxy bond to wood? what if you used carbon fiber as a laminate in a multi lam setup? just the carbon fiber fabric? used it sort of like an accent strip? just a childs' meandering here but something I wonder about.

noice... what do you use for hold downs?

real smooth look to the back there. nice color balance between teh pickup ring, binding and fretboard. good work.

When I 1st heard of this song I had no idea who Lindemann was. And I thought that sounds an awful lot like Rammstein then I looked it up and find out it was the dude for rom steed so forgive my confusion

interesting... it kind of goes along with what I was seeing on the fishing poles. they put them in a heater, and afterwards they are 'bonded'. Not sure that would be possible as a consumer but... all that said I would still be curious of what sort of results you could get. actually, if the carbon strands are 70% as effective as the commercially available rods it'd be worth it. I could see multiple applications (inlay carbon fiber strings on as runners on the back of a neck). further, parker fly used carbon fiber on the outside of wood no? Did they use heat? My gut would guess no as that might cause issues with the wood, but I honestly done know. if they didn't use heat... what sort of resin where they using?

omg... well on that note... yesterday she comes in and I'm watching fishing rod videos while I'm also watching the song 'fish on' by ramstein. someone at talkbass referenced that song and I never heard it before and I'm blushing even now thinking of the lyrics. she gave me an odd look. highly recommend you go listen to that song!

that WOULD stiffen it.

well, I think @curtisa's point about comparing to mfg carbon rods makes more sense... after all that is the thing we are really interested in the comparison to.

as it was described in the thread... it works a lot like concrete with rebar inside it. The two separated have very dif properties than the two together. rebar is in fact fairly easy to bend... concrete is fairly brittle. reinforced concrete is fairly resistant to both. to some degree... by pushing down on the carbon fiber with the filler block, and assuming you laid the strands in there straight, you would be sort of making it taut. as curtisa said, there's little doubt it would add some amount of stiffness but is that equiv of the stiffness achieved by the pulltrusion process? only one way to find out.

right on. there's pulling and there's pulling. I guess it all boils down to what sort of tension is involved in pulltrusion of their product. I think an experiment would be pretty cool... putting that on my 'when I have time' list. could just use a similar weight and measure the amount of 'bendiness' - awe there I go again (hehe). I was thinking I might ask bruce if he has any documentation but I don't want to insult (like who am I asking him to prove it). did a little searching to see if I could find any such tests but no luck. at the very least... we come out of this with a conversation I enjoyed quite a bit. at most, I'm going to snag some of these materials and try it at some point. will def share the results.

you know it's hard to argue with that reason. I didn't know they actually pull them taut when they make them. hmm... kind of changes my mind on it - thank you for that. over at racedayquads you can get little tiny cones (possibly single strand?) that would kind of give me the same possibility for using less of it and yet adding rigidity. afa rods... well... yes. but we don't really want perfectly rigid and we don't want super bendy. are they more flexible than maple - yes. is it more rigid than a hollow maple cone of the same size? I would guess yes. before you ask "bendy" is a technical term we use in the engineering industry. In laymans terms it means plyable. I hate to use fancy and all but sometimes I accidentally slip into engineering mode and can't help it (heheh)

nicely done. that's a lovely bass.

well... as I understand it... the carbon fiber rods you get are not pure carbon fiber. Bruce explained in that thread that they were (allegedly) similar carbon fiber fillaments encased in what I thought he said was a polyester resin? so... in effect... his argument was that the carbon fiber rods you buy are adding in a bunch of plastic to your neck. He also argued that the typical carbon fiber rod is is much bigger than you even need. he said he adds between 2-12 strands of that TOW and that is enough. The benefit being that you can place the carbon fiber below your truss rod where it actually benefits the neck strength more as it's closer to the back of the neck... and you can use a very thin layer of it and very little epoxy... and according to him, that is enough to make his necks quite rigid. Half the reason I posted it here... was to see what you guys thought. Like you, I had the very sm questions "how could some carbon fiber thread possibly reinforce the neck?" While he sites that he has done vast testing privately and for commercial builders... I see no evidence. the only thing that I can offer is that bruce is (apparently) quite popular at talkbass and does neck builds commercially for a number of builders (who... i dunno). The number of 5 and 6 string bass builders on that site that acknowledged/sited him as credible made me think that perhaps he's on to something. that's enough to pique my interest. what we need now is a way to test this. so... assuming I go out and buy some carbon fiber tow thread at some point... and some west systems epoxy... what? make a little cardboard trough and put some strands in it and pour in epoxy and compare the strength of that to another trough that I just fill with epoxy and say... nylon string? also, just wanted to mention... the primary benefit/goal of bruces' method was that you can get 1000 ft of this fillament for $30. ie... it's not only potentially better, but it's much cheaper. so for $30 if you do 12 4' strands per guitar... you can do 20 guitars. all that said... in the process saw two different inexpensive places to buy carbon fiber rods... https://www.racedayquads.com/products/1-meter-carbon-fiber-rod-1pc-choose-your-size?variant=31470540292209&gclid=EAIaIQobChMI_dqLyZvE7AIVfCCtBh2JCAnNEAQYBSABEgJt3_D_BwE https://dragonplate.com/carbon-fiber-rod also... in watching the fishing rods being made... they literally take carbon fiber fabric... wrap it around a metal rod... then heat it... then pull out the metal rod and you have a fishing pole. what does this mean? i dunno... but fishing poles are incredibly strong... I always thought they were solid on the inside... but apparently they are completely hollow. in the process you see this limp fabric rolled around a rod become a fishing pole.

and then my wife wondering why I'm watching videos about fishing rod production... https://www.google.com/search?client=firefox-b-1-d&q=making+carbin+fibre+rods#kpvalbx=_1NGOX4yvDI75-wT1vpiYBQ13

fascinating... it's a good question curtisa... and as a result I have been reading some more threads... here's bruce putting it to work... https://www.talkbass.com/threads/my-les-paul-bass-build-i-need-a-gibby-too.1120298/page-25#post-17990278 I suppose... the way he is sandwiching it in there... doesn't pull the carbon taught... but def is putting some pressure on it.

well, not according to bruce. I imagine that could certainly improve it. that said... once the epoxy dries... the epoxy would be working with the carbon fibre. as I understand the carbon fiber has pull strength... and the epoxy has sticking strength... so the epoxy is essentially holding the fibre to each mm of space... and the carbon fibre's pull strength would be engaged by a bend.

so was reading this thread over at talkbass and thought many here would find it a valuable resource...I see a lot of great applications for this... esp the idea that you can make a much smaller grove for neck reinforcement and not have to worry at all about a tight fit between carbon fibre rod and slot... https://www.talkbass.com/threads/less-expensive-carbon-fiber-reinforcement.1287574/#post-20099564 the jist is: you buy 6K TOW carbin fibre thread, cut a slot... fill it with thread... then fill with epoxy. def going to use this on upcoming basses.

noice... I'm told the maloof is a really difficult build. should be a lot things to learn on that one. vcool. afa veneer... just a thought. nothing wrong with hardtail. rock solid!

right on, well don't be a stranger! would love to see whatever you are working on these days!

please do share your experiences on the rocking chare in the 'non guitar build' section as I've been thinking about a rocking chair myself. terribly interested in the topic. guitar is looking great - if I may.... please please please do some kind of matching headstock overlay. that body pairs so well with the headstock... overall guitar has such a soft appeal... headstock veneer with the sm tone would really take it to the next level imo. also hardtail eh? "I like the cut of your jib"

well I spose it's a lot like the code for air traffice control. probably written in c back in 1992 and no one willing to take a chance on updating it!! that interface is straight windows 95 for sure. I've seen a black version of the interface but I think it was just someone with a skin (I don't think this thing would have themes... but I haven't tried to figure that out yet). My first thoughts on playing with it were "really, everyone across the industry who runs a cnc machine is using THIS interface?" Have to admit tho... it is pretty rock solid functionally.
