Filling in between sheds.

[B R C]

I have a 24’ space between two sheds both same height length. I’m cutting down some 20’ rafters to 12’ with new end plates. Shouldn’t be too taxing but if anyone has any hints? At the moment thinking make A frame i10mm too short and shim as necessary, as it would be much worse if it ended up being 5-10mm too long…

thats what i would do

have you measured to see if sheds are parallel?

Can we have some progress photos please.

measure very one with a steel tape and measure at the top were you are going to bolt to things are not always as thay seem

We are going to, sheds were built parallel but you never know. Too sunny to see the laser atm, will do a bit more this evening.
Progress so far….

Pick your narrowest gap and work dead size to that or slightly under- shim the rest.

Finger pack shims from your local profiler or drill and slot the holes in varying thicknesses work best.

Make one rafter and use that as your template for the remainder- you only have to set your purlin and end plates out once then.

Possibly consider some bracing in the end bay but make it fit afterwards as you don't know how square the sheds are to each other.

Good luck with it

Filling in this

Pleased that max difference between stanchions at eye level is 15mm so no reason to think they’ll be much different at the top, first pair were 8 mm difference top to bottom.
Plasma wasn’t so keen on 15mm but adequate, top plates cut and template for mag drill made out of 3mm

Is existing guttering big enough to cope with extra rainfall from new shed?
Also how will you position rafters so that rainwater falls in gutter?

 

[B R C]

Existing gutters remain, new gutters for new bit about 12-18” below current.

Does this mean you cannot fix rafters directly to post??

 

[B R C]

Rafters fix to post, once I’ve cut a hole in cladding, and drilled holes.
I am trying to figure out how to fix gutter, the shed I’ve just looked at had an rsj an as eaves beam that the gutter rested on which seems a good way as it means you can also walk along it when needed.

 

[AJR75]

You could always crank your new rafters to accommodate a box gutter?

I'll be interested to see how you solve the 'Gutter Challenge'.

Its pretty easy with a steel box gutter. Especially if the eaves of your new shed is slightly below the existing.

 

[Sharpy]

It's really pretty simple.
Set up your fill in shed rafters with a horizontal plate on top of the rafters at each side ideally about a foot wide. Get a gutter folded to sit on these plates to catch the water from both your new roof and the old, this will also allow you to put the new roof at the same height as the adjacent roofs. You really want it wide enough to be able to walk along it with a brush.

As described above. Flat plate on top the rafter to carry the steel gutter, eaves purlin further in to make space for the gutter & bolt it up. We put a higher shed on the side of the original but basically the same principal.

A bit of progress today, plates all drilled and one A frame made up, I think I’ll just put in a decent thickness centre gusset rather than a flanged gusset, should be fine as rafters now shorter and the end plates are 15mm rather than 12mm as I haven’t got any 12mm.

I will add, I replaced a leaking gutter, with a 6" piece of channel, which was long enough to do the whole run of the leantoo, excellent job and much better than the leaking old gutter.

Interesting, I think it might be a bit expensive at the moment with steel circa £1500/t, I need 60m total. Also with 180mm purlins I would like the gutter lip to be quite tight to sheets so probably 150mm deep, I can lift the gutter with the flat bracket that I need to fit to on the end of rafter.
