Finger Joint Studs - How And Why?


My crew and I were discussing how finger joint studs are manufactured, and I was just curious if anyone has perhaps a diagram or a link to somewhere that would show me what exactly the process is. It seems like the FJ studs here in BC's quality has been going downhill for a while now.. Has there been a change to the process of their manufacture? We're convinced that we're shipping all the good stuff to other countries. But even something as simple as the glueing of FJ studs isn't even always done properly. Have you ever opened a lift of studs and had EVERY SINGLE ONE fall apart because they weren't even glued? Or on the other end of the spectrum, had a whole lift GLUED TOGETHER?
Anyway, if anyone could send me in the right direction to find out the details in the manufacturing, thanks.

Check out the West Fraser website.. If you are in BC, there's a good chance a lot of your finger jointed studs are produced there.

Re: Finger Joint Studs - How And Why?


We had several lifts do that. From what i heard from the lumber yard is that the FJ manufactures work of supply and demand big time, and because so many people aren't big fans of FJ studs (I have no idea why, there the best!), they have some lumber stores with lifts that don't get used for a year, so when your local yard runs out, they call other yards and get there old lifts. we had a couple lifts that were two years old. Full of ants and all the glue was wet and nothing held together. Just send em back.

In Ontario the best brand of FJ studs we could find is Lamco studs. 7/8" long finger joint, which is the biggest I've seen. and guaranteed 5 FJs a stud, which means straighter studs, shorter piece means less chance of warping. They are hard to get a hold of though.

Re: Finger Joint Studs - How And Why?


The thing that would dissuade me is the fact that they are "vertical use only".. i don't want to send a search party out to different piles to find sticks.. Pick it and go.

The fact that sometimes the 2 year old stack just falls apart should scare the dickens out of you.

Re: Finger Joint Studs - How And Why?


It's an engineered product. No decent yard should leave LVLs, TGIs, or OSB just laying around untarped. I'm guessing the one we got the old lifts from had them laying around in the back corner untarped and covered in weeds.

As for vertical use only and having two different piles, you get used to it. I don't know to many framers that are cutting studs up for other things other then jack studs.

Re: Finger Joint Studs - How And Why?


There was a Boise-Cascade ad in the late 70's that showed a bunch of plant employees carrying an fj 2x4 that was like a quarter-mile long out of the mill. Pretty impressive at the time.

We used to get fj 2x10 joists sometimes back then, but the glueing was different for structural.

A couple years ago we couldn't get fj studs for a green project because the plants closed during the slowdown.

I don't know about New England but we use them around here all the time. All the ones I have seen are really bad quality, not straight, falls apart.

Re: Finger Joint Studs - How And Why?


a FJ 2x10 joist sounds like a pretty ridiculous idea...
and i think FJ studs are common anywhere in North America..
we never request them they just kind of randomly show up... and a lot of people say theyre always straighter and truer on average than non FJ... but i beg to differ. not to mention in the wetter months the FJ lifts are usually covered in mold

Lvl studs are awesome. And perfectly straight. As long as they're stored properly.

Fj studs are being phased out according to my engineer due to inconsistent construction. I never order them. But I've built with them.

I know Jesse around here is only framing with LVL studs or something like it. He said its awesome to frame with, beautifully straight with zero culling.

Didn't the FJ studs make a showing during the US Ban/Restriction on Canadian Lumber...along with the >engineered< studs with holes in them for electric? Ban was on lumber not "engineered", funny loop hole

Re: Finger Joint Studs - How And Why?


Do you mean lsl studs? I've used those plenty but have never even heard of lvl studs. I'd think the cost would be nearly triple that of a dimensional lumber stud...?
