Hello, I am planning to install 14″ solar tube, the joist is 14″ center, the rafter is 24″ center. I want to install the tube straight but the rafter is on the way, and because the height from the ceiling to the roof is only 18″ plus the height of the flash is 10″, even I try to twist the tube, I can’t make it. So if I can cut this joist, see pic. Thanks.

Thanks Rez, it works. :-)
Sure, but use glue and structural screws instead of clamping the sister.

No. You aren't resupporting that the right way.
Yes, but that would be considered boogering. I can guide you in this procedure but I'd need to know more.

you are so right. and more awake than I :) thanks and good night.
Make the sistered piece overlap the cut joist at least two feet on each side of the gap.
Use polyurethane glue and four 5/16"x 4" hex bolts on each side of the cut. Use thrust washers on both sides of the bolts, too, to prevent the head and nut crushing into the wood as you tighten it down.
Set the four bolts in a staggered pattern so that no two bolts are the same distance from any edge.
Note: If you've never used polyurethane glue before, you need to wipe down the wood with a damp cloth before you spread the glue on. This type of glue cures by reacting with water, so the wood needs to be damp. The glue will start foaming within a few minutes, so once you've got the glue spread, assemble the joint right away and clamp down on the bolts.
Don't try to wipe off any foaming glue that squeezes out of the joint; wait a few hours till it's dry then trim the cured foam with a razor knife if it's in your way.

Piffin, I meant clamp a new piece overlap as the pic then use screws to hold them. Thanks Dinosaur with a detail iView Imagenstruction.

So granted that there are many roads to Socialism, Premier Khrushchev...I'm curious why Gorilla glue and bolts as opposed to PL and 3" screws or sistering the joists to either side and then capping the severed joist with a single/double header? (guessing the one side is close enough to the eave to use just a single on that tail)Inquiring minds and all that.'Man who say it cannot be done should not interrupt man doing it' ~ Chinese proverb

Wonder how they did it in the olden days, before Gorilla glue. I've pretty much banished that stuff because of problems unrelated to glue bonds. Like glued hair, black spots on my hands and whatever else, glued clothes, glue foam out, short open bottle life, etc.Id just spike on a 8' splice most likely.
You can lengthen the open bottle time by squeezing the air out of the bottle before you cap it. And a tyvek suit and nitrile gloves will fix those other problems.

Very funny comrade!Thanks for the info. Was just wondering if any of those methods were functionally superior to the others.Now, what's a thrust washer? I see a bunch of references to auto parts and universal joints, but nothing that makes me stand up and say 'ah'.'Man who say it cannot be done should not interrupt man doing it' ~ Chinese proverb

What is talking about is not a thrust washer. Just a plain hardware washer to help spread the force of the head/nut on the wood.A true thrust washer is a one that is designed to help control the thrust from shaft or a bearing. And they are tightly machined product.Often they are used with shims to help control the play in a shaft.Here are some..

Is that one?

I stand corrected. And thank you, Bill. As usual, you're right on.

Actually I don't use Gorilla¯ brand glue; I usually buy PL liquid P-U. Doesn't matter much; the point was to use a structurally-rated goop of some sort and polyurethane glue meets that standard.
I like thru-bolts and thrust washers better than screws for this sort of thing as the likelihood of stripping out the wood is nil with a bolt, while it's fairly high using screws now that ev'rybody and his maiden Aunt Millie has a 24-volt LiOn impact gun. Didn't matter so much in the old days when ya had to pre-drill and wax yer slot-heads, then drive 'em down by hand....

Very improtant before you cut...do you have trusses in the attic?
You get out of life what you put into it......minus taxes.

Not likely with a description of rafters at 24" and joists at 14"
Welcome to the Taunton University of Knowledge FHB Campus at Breaktime. where ... Excellence is its own reward!
Do you think glue of any kind is needed?
Edited 6/29/2009 11:38 am ET by Dam_inspector
Yesbut there are a half dozen variables here that could apply to this answer. Short and sweet is just do it.Like how long is this joist and what load does it carry.
If carrying a storage area as well as the ceiling and insulation, maybe it should be double sistered and headered instead.how good of lumber is it?is he using screws ( what kind) and or nails?Is there strapping in this ceiling?unless this is terribly unigue, just gitterdun
Welcome to the Taunton University of Knowledge FHB Campus at Breaktime. where ... Excellence is its own reward!
No, I have 16 ceiling joist on this family room, none of the rafter is pair with it as I see in new home build. As the joists are 14" center, and the rafters are 24 in, they're barely meet... The rafters have their own joist near on the top....

I second this...
Pesky 'ol framing holding the house up! What were they thinking putting that there?
If it's conventional framing, you should head it off instead of sistering something next to it. Will the sister work? Probly for a while. I'd spend the time to head it, though.
I'm pretty sure you don't want to cut a truss.
That's my 2
