"After cutting 6 necks from 2 - 1x2x8ft Poplar. When I got to the last scarf cut, I read the UPC tag - premium pine..Any problems with bowing?" I built one neck to test. I used 3 E strings (52 g). After retuning a couple of times (new strings), on the 3th day there was only a 1mm bow, and it had stayed fairly in tune. I was looking at the canjo videos with Ben Baker, and he mentioned that larger dia. strings put more stress on the neck. Has anybody out there had a problem with using premium pine on a 3-string, or should I use this batch for canjos? Thanks
I have used broken hockey sticks for necks no issues. I do not know what scale you are using , 1mm of bow with 3 E strings. I would say it would work for a 3 strings . I don't know how well the pine will hold frets if you are building a fretted instrument . You may have to use hardwood fret board glued to it.Build one see what happens. Just my opinion.
Thanks Erasmo. Sounds like a good idea.
Using a hardwood fret board is going to strengthen the neck and help resist bowing.
I used Pine for the neck on one of my 4 stringers. I knew it would probably bow, so I glued on a Red Oak fretboard. It still bowed. I then removed the fretboard and cut a channel for a trussrod, installed a non-adjustable trussrod and glued the fretboard back on. The the headstock bowed a little, but now it's stable.
If your Pine or Poplar neck is flatsawn and doesn't have a trussrod, I wouldn't use more than 3 strings for a scale longer than 25.5"
If you can't find any quarter sawn boards, take a couple of flat sawn boards and glue one on top of the other. Then draw a neck with headstock and heel from a side view, cut it out on a bandsaw, flip it over 90 degrees and glue a fretboard on it and you'll have a multi-piece quarter sawn neck. LOL
Lots of ways to strengthen a neck if you sit back and think about it awhile.
Also remember that the wood you get at the big hardware stores are most likely still green.
ever notice that balsa is considered "Hardwood" lol
Yeah that's messed up.
The Pine I used was Southern Yellow Pine(a glorified weed) and is probably the softest Pine. That's the Pine that's mostly available here. Pine, Aspen and Douglas Fir from American west is good. Guitarist Bill Kerchen (Hot Rod Lincoln fame) has a Tele body and neck made of Western Pine without a trussrod and it has remained usable sine the 60's. Just depends on type and location.
That Radiata Pine sounds interesting Chris There's a Asian wood called Paulownia that's very light/soft that people rave about tone wise. Wonder if it's an Asian Pine?
Laminating pieces is supposed to add strength, but all pieces used have to be straight. Gluing one piece to another can react in a negative way(bowing), lots of clamps and leaving it clamped til they completely dry can take more time with whether/moisture levels. I glued 2 pieces of Red Oak with a non-adjustable trussrod once that had too much back bow and had to be used for slide playing. You really take chances all the time with wood, you never know how it's going to turn out. Might be good, might not. That's why it's good to have an adjustable trussrod, but I wouldn't worry about it on a 3 stringer.
Ditto what Chris said,.,,.I have used Pine for half my builds.,,.the hardwood fingerboard does add strength.,.,and I know of a well known Ebay seller that has built and sold in excess of 3000 Pine necked CBG's with good results.,.,I say If your concerned you could always make that batch "high strung like a dulcimer .,.,
That canjo looks great. I am of the school that pine is fine if you add a glued up finger board.
Thanks Uncle John. The neck is all one piece, just painted the lower half. Used copper wire for frets.
