Stirling work!

I have probably missed something but what is the horizontal gap on the LHS (looking at it) for? And those mortises on the door timbers for?

Thanks guys. Great fun day. One of those days where you can definitely see where you've been.

Well, there was about 8 or 9 days preparation went into that one day. It certainly gave one or two drivers a bit of a shock, though. Nothing there in the morning, and a complete frame there in the evening when they went back past.

The slot is for a letter box. I didn't want to spoil the door with a hole, so i put it in the wall instead. The mortises in the outside face of the door are for a canopy over the door on gallows brackets, as per this drawing, (roughly):

Image

There are also long mortises on the door-facing part of the posts, and they're for the spandrels to form the 4 centred arch for the door head.

There'll be a pair of rafter fixed to the wall of the house, not on show, probably with a little horizontal member below in oak, on show, to hold the ridge beam. I'll have a longer think about that tonight. There are alternatives.

:eusa-clap: Oh yes, well deserved cup of tea Mike! Bravo bravo! 8-)

There's an awful lot of work in that; working out, marking up, all the jointing, heavy lifting and assembling etc etc, and to do this by yourself in the time you have deserves a proper stand to attention salute! :eusa-clap:

Moving onto your roof, I can see a couple of changes from the drawing to reality which is normal with most projects (including furniture), but to clarify; it looks like you're going completely traditional - not plumb cutting the rafters into the ridge, but going over the top with a halving or similar, and seat cutting (no bird's mouth) onto the head plate with sprockets from there out with closed eaves. Are you plumb cutting the rafters at the head plate before the sprockets go on?
In my previous life, I was a tree.

The savolit boards sitting in the rebates - do you seal them or does the rendering take care of that?

Hi Paul. Astute questions.......

The pair of oak rafters at the front will, as you say, be bridle jointed at the top, not plumb cut. They're also birdsmouthed over the ridge beam. Behind that, the rest of the roof is softwood, which will have a plumb cut at the ridge. However, they don't meet the oak ridge beam, deliberately, for reasons which should be clearer when I show the photos this evening. There will be a softwood spacer on top of the ridge, over which they'll be birdsmouthed.

All rafters, as you say, will spring from the outside edge of the eaves beam with a seat cut, and an oak sprocket will be fastened over that.

As an aside (I forgot to mention it last night), I was originally going to have the ridge beam sit on a jowl on the King post, so as not to penetrate to the outside. After going back and forth on that for a while, I decided on the easier option. This is a porch on a cottage, not a vaulted roof over a mediaeval hall!

Rendering does that. It's what these boards are designed for.

I've been a bit distracted messing about with the picture hosting but I have found time to keep up with your progress.

Hard to think of some new comment to make. How many times can I say impressive :)

You tackle things that would daunt the best of us like they are easy jobs and at such a pace. Sure I've said thanks for posting before too but it bears repeating - thanks.

Thanks guys, much appreciated. Really, these positive comments do help through some of the more tedious days.

I worked for 10 hours on the porch today, and it looks exactly identical to how it did last night. So, I'll wait until tomorrow to post some more photos.

Wow Mike, looks amazing.
Im really interested in the render boards. The interior of our farmhouse was all covered in those render boards and plastered in. It was an absolute nightmare, joiners here gave its nickname, the grey death for Oak framed buildings. After the war it was a wonder construction material for modernising old buildings and combined with poor choice of cement based plaster it has caused so many problems trapping moisture against and within the frame. They literally used it everywhere.
It was an absolute pain to get rid of as it cant be recycled and they hate having it in skips (different waste types have a different prices, all by weight).
I can see how when used with lime based products it would work well. What are you planning to use as insulation and finish behind the board?

That's a very different stuff from Savolit boards, which have only been around for a few years, and can be recycled. They're vapour permeable, too, so they don't trap moisture, and work well with lime render.

Next on the list was the roof. These were the easy part:

Image

I had thought long and hard about how to make the oak rafters at the front elevation. They were a real complication, because you need the ridge in place to mark out its location on the rafters, but the ridge stops you getting the rafters in place to mark anything out. So, I decided to make the softwood rafters, and use a pair of those to capture the position of the ridge beam:

Image

Image

Image

Image

Image

Having got the birdsmouth over the ridge beam sorted, and the feet cut, I then offered the rafters up into position to mark for the joints with the tie/ door head, and the little window heads. There is a big bridle joint at the top, and I made this next:

Image

Image

Image

That one joint was nearly half a days work, and, frankly, it was a little too loose. I also chopped out the mortises for the connection to the tie beam/ door head.

The joint on the end of that tie beam looks a bit odd because it is joining a 5x5 piece to a 4 inch wide rafter:

Image

It went together absolutely beautifully. I couldn't have hoped for better:

Image

Finally, the little window heads which retain the rafter feet needed their joint doing:

Image

Image

At this stage, the porch had gone backwards from where we were a couple of days ago:

Image

Time to start putting it all together again.Window heads on, tie beam on, and a pair of rafters fixed securely to the house. Before doing the latter I had trued everything up and got the walls exactly where I wanted them (they still flapped about a bit at that end):

Image

I put in another temporary ridge support beam, whilst I come up with something nice in oak. Then the ridge went in:

Image

Finally, I could offer up the oak rafters, and located the Savolit infill panels:

Image

The only way the rafters could move was horizontal, because of the tenon on the tie beam. I had to wax all the bearing surfaces and all the joints, and get my biggest sledge hammer. It took some messing around, and lots of loud hammering, but everything dropped into place beautifully. I captured all the pieces top and bottom with stainless steel screws, with pegs to follow in the next day or two:

Image

Finally, I was able to nail up the softwood rafters:

Image

Image

There's a reason for the odd spacing, which you'll see tomorrow. You'll also hopefully see oak sprockets, and membrane and battens, giving us a watertight roof.
