I was wondering if anyone has any tips for wrapping sills that are beveled with a slope. I know how to wrap 2x4 and 2x6 sills that are installed at a slope by leaving the ends long and capping but I have never wrapped a sill that has a bevel cut on it for slope, seems to me that if I were to bend by metal and then fold the ends over that it wont cover right. Any pointers would help, i've looked allover the internet and could only find information on regular sills.

There are a couple of ways that can be done depends if you are just capping or if the will be J next to it . with J you could leave it long enough then tab th bottom up , front in then top down , would be sealed pretty well. Or you could leave it long then snip the top and bottom , with a hand seamer straghten the top and reshape to the angle you want it then fold it in . Nice clean end on the cap. This the way I do it most all the time. Hope this helps.

Do you have any pictures Randy? There is plaster on the outside of the house, the plaster is coming off so we can blow in insulation, we're tyveking and then siding. The plaster is about an inch thick which means I will probably run my power planer along the sills to make them not stick out so much. I'm worried that since the sills arent square on the end when I cut to do my cap it wont look good. I'm also using smart trim on my sides and head of the window then using J next to it, maybe the thing to do would be plane the sills down to be flush with the smart trim which is 5/4 and then I will only have to worry about covering only a 1/4 inch on the end of the sills since I'm using 3/4 J.
If im following what your talking about it wont look right to have your sill flush with the trim. If the existing siding is 1" and your using 3/4 J the difference isnt enough to matter. I personally think it looks much better for trim to be proud of the J anyhow. How much bevel is on the end of the sills? If your retrimming the casing could you just cut some of the bevel off and make your trim a bit narrower? Its not like your wrap has to be super tight anyhow, i always like to leave it a bit loose to allow for wavyness and contraction.

sills are supposed to stick out,the more the betterer don't plane them down:no:
Nice looking job, hard to tell from the picture , but how far in are you capping? To the stop and then caulking?
I wonder if the OP was talking about the older windows that have a lot more slope to them , seem like they use to be about 12 degees or so. If the windows have a sill that sticks out more then top and sides I like to leave them that way.
I always hate capping the old single pane windows hard to do it right so no water gets in .

The silks are sticking out about an inch and a half already, i'll be removing the plaster which is another inch and replacing with 3/4 j which will make the sill stick out an inch and three quarter. One person mentioned that the old silks were a pain to wrap that had about 12 degrees on them, these are probably at about a 15 and over 70 years old. I'll get a picture tomorrow and everybody can have a look. Thanks for all the responses.

Since the casings were off and the sash removed for replacement, I capped the entire frame and sill. Sill is a 1 piece profile with corners rolled up and caulked. The other sills I'm fabricating out of PVC on this job are ripped to 13 deg.
I would, If was you.
Tear off exterior first.
Tyvek.
Then wrap windows and doors with a nail flange / water flange.
Don't worry about the sill sticking out. I have wrapped window sills that have taken 18" of coil.
Sills should always be out farther then your sides. If there not we build the sill out at least 1".

have to agree with tom. You start planing the sills and your messing with the integrity of the home they were built with sills like that for a reason.
