Attaching rafters with rafter ties...

[mdbokc]

You need to use a modified ceiling joist if you didn't notch the rafters. Normally, the ceiling joist is attached to the top of the wall plate. However, you are going to set the joists on top of the wall plate and attach them to the rafters.

Okay, for the record I'm using the 2x6's because it's a shed style roof. None of those brackets will fit because it's rough sawn/mill lumber which isn't the standard 2x, its more like 2 1/2" x. I'm going to notch, it's not the end of the world.

It's actually a 3 sided shelter for the horse (and chickens if they feel so inclined) to use. It's a floating shed, so no posts going in the ground due to a serious lack of soil LOL.

Thanks for all the advise! I'm going to notch and put the hurricane ties on for extra support

So how did you locate roughsawn lumber? I would really like to get some myself but the local farm stores and lumberyards don't know and don't care. Any suggestions?

I am totally not understanding why the dimensions of the lumber has anything to do with whether you can use hurricane ties of the type you pictured -- but it *is* more secure to notch AND use those ties. Make sure to notch only as little as possible, i.e. so the horizontal part of the notch is ONLY as wide as your top plate of your wall, as cutting away any more than that weakens your rafters.

Good luck, have fun,

Pat

For large projects requiring good sized spans and a roof which needs to take a fair load, we use these type of hangers ..... http://www.screwfix.com/search.do?fh_search=joist%20hangers&cm_mmc=Google-_-Building-_-Builders%20Metalwork%20-%20Hangers-_-Joist%20Hangers?P=P&gclid=CJHz9qyItp4CFU0B4wod1AkElg&source=aw

Will take 2 x 6.

Mark.

Sorry, forgot to say, no notching required.

I can tell you my 2x6's cost .50 cents a linear foot, they're very reasonably priced. They do dressed lumber and hardwoods, flooring, siding as well. And heck, it's a nice drive

Plus, since I know you have horses... we have some great tack shops out here

Oh and, I AM going to notch and use the hurricane ties. The rafters will be sitting on a dimensional piece of 2x10 which sits in a notched out 4x4 post (carriage bolted through).

For the record the ties I listed I CAN use, it was the ones that require no knotching that I can't because they're a complete unit meant for home depot type/dressed dimensional lumber.

Rafters have to be notched no matter what you make them out of, UNLESS youre building a shed roof and angle the top plates on the walls

I am building a shed roof for my coop. It is very small. About 4x4x4 framed with 2x3s. I was going to do the rafters with 2x3s as well. Tried some bird mouth cuts out of scrap and there isn't much wood left when I do it that way?

Could you advise me? I am not sure I want to put heavier 2x4s on a 2x3 frame. Seems like for such a small building, I don't need go through the standard methods. My build has slowed because I don't know what to do now?

cutting the birds foot for rafters is really easy. set one rafter in place and mark both sides of the top plate on both ends, label which line is the inside the coop line.

Use your speed square to mark a triangle on each end. the up hill side will have a 90 degree angle on the outside the coop line and come to the inside the coop line at the edge of the board. the downhill side will be the opposite.

Use this first rafter to test your cuts then use it as a template for all the other rafters. easy peasy.
