Great update as always dnme! I know what you mean about those runners making the job solid, it's a great feeling! Not long now until it's a shelter, it's regally coming together. Well done as always

BTW

Seeing as I'm on a forum, there might be people from the trade etc knocking around. I was wondering if anyone can advise or get a trade deal on pvc roof sheets? Is anyone in the trade watching, or perhaps knows anyone in the trade? It's expensive stuff and I'll take any help I can get.

A friend passed me this link, I havn't contacted them myself yet, but your project is advancing much faster than mine. http://www.celuplast.com
Also ploughing match is on this week, might be a good place to talk to agricultural suppliers.

Some questions if anyone can help....

When laying the pvc sheets, where do I start? Will I start at the L over the back door or the other end (outer end)? I have a feeling the house is not square so I will have a taper to cut in opne of the sheets lengthways.

I will have 4 runners. How many fixing screws should I use at each runner per sheet (crossing a 2ft span)?

Should the last fixing screw go through the overlap between the sheet and its previous neighbour?

Many thanks

Start over the door and work your way out to the gable.

3 screws in each sheet and 1 on the joints.

Might be worth taking a few mins to put them up there (a dry run so to speak) so as you get a notion for it and see how square or not the house is. That said one will need a calm day to do this - sadly lacking in Ireland as you can atest !!!:)

dnme · 19-09-2011 1:02pm

How would you solve this?

vicwatson · 19-09-2011 1:31pm

Screw a piece of timber up into the fascia (underside) to bulk out the space so your piece of timber can then be screwed into that piece.

Does it have to go above the grey door surround?

The gap to the facia underside is bigger than image indicates (8cm) so a bridge block may not be an option. I was wondering if I could use strapping to hang the runner out of the facia?

Just to be clear, do you mean 4 screws across the sheet, the last one on the overlap? 4 runners each x 4 screws = 16 screws per sheet. Yes?

vicwatson · 19-09-2011 1:55pm

Hows about using the likes of this, or something similar ??

Or how about an "L" bracket under the timber and into the wall with a rawl plug ?

Have you another longer 6*2 by any chance?

I would use a longer 6*2 and extened the extra foot or so (at least). You will need to rebate for the reveal and cut over for the corner of the door. I thing its the neatest solution.

The easiest is a wall hanger. If you use a strap, won't you have to cut a hole in the perspex sheeting?

TopTec · 19-09-2011 4:53pm

Presumably you are not looking to attach that runner to any wall plate, only to secure it to the house?

If that is the case I would go with VicWatsons idea - bulk out the space above with similar width stock, screwed and glued to the top of the runner under the eave.

From a neatness viewpoint you could then plane the underside of the runner upwards at an angle that finishes above the door frame. If you extend the insert slightly so that it touches the house you could used a couple of angle brackets and fix it to the wall.

It does need to finish above the painted frame otherwise it will look odd and will be the first place we all look when you have your launch party.

:D:D:D:D

Ive strapped it up to the facia and soffet. Looks ugly but its secure.

Yep.

Got the sheets sorted from Reynolds in Carrick on Shannon. Managed to get a 5% discount too. I'll collect them tomorrow or Wednesday.

Tell me, fitting these, is it much of a reach across their width? I presume I fit them by screwing down their length rather than across as per the images?

#1

#2

The reason I ask, is that at each fixing, I need access to under the pvc sheet to place the stand-off (see image) #3) and I imagine that the sheet will flex up (allowing this access) far easier along its length than across it.

Also, do I need to pre-drill? and do I need to oversize the hole for expansion ?

Can anyone answer my questions in post #136. Many thanks

Pete67 · 19-09-2011 10:18pm

This might be useful?

TopTec · 19-09-2011 10:30pm

dnme, The only time I used these sheets I recall them being more flexible widthways. Therefore it makes sense to fix the first corrigation along its length then the next corrigation and so on.

Your last fixing of one sheet will be over the top of the next sheet. So your Fig 1 would be your first line, then four corrigations along and so on.

It still helps having tiny fingers and more arms than an octopus but this is one of those jobs that you will find your own way of fitting.

Happyman42 · 19-09-2011 10:38pm

On a fall like dnme's is it still the case that you should only screw through the high part of the corrugation?

Great thread btw dnme!

vicwatson · 19-09-2011 10:38pm

Good info here too -

That tells me to drill the holes 8mm to 10mm. That seems massive to me, the shaft of my fitting screws is 4mm. Do I really need 6mm left for expansion ? I'm just wondering if anyone here has actually used these sheets before? How'd you do it? Here's what I'm thinking......

-Place the sheet.
-Mark my drill points
-Take down sheet, turn it upside down and drill all holes 2mm bigger than screws.
-Maybe thread each screw / standoff through each hole while its still on the bench, adding a blob of silicone sealant to each fixing.
-Put sheet back up, screw fixings down.

How does that sound?
I wanna get this reasonably right from the start. I cannot afford a "learning curve" with this job. Stuff is too expensive.

vicwatson · 19-09-2011 11:15pm

I think this will be quite adequate.

I don't have much experience with this stuff, but if it was me that sounds about right and even if its not the text book way to do it, I can see zero reason why it shouldn't work. Definitely do the screws in the order you said, go length ways first, so much easier. I know its not much, but its a second brain telling you that it seems right!

Day 10

This day last week was hurricane whatzizname, so that means I would have started the construction part of this project last Tuesday. Well it's up and waiting the pvc sheet. That took exactly one week. That's not bad going I reckon, although I did suffer the consequences by enduring all kinds of weather, the sort of stuff normal decent human beings would down tools for and retire indoors.

I drove down to Carrick this evening to collect the sheets. I have an old Corolla liftback. The boot is massive and the rear seats fold down so I thought I might get away with it. No such luck. They would not comfortably fit without the possibility of doing some damage so I had to ask for the sheets to be delivered. Another 20 dam quid. Hopefully I'll have em tomorrow.

In the mean time I have been slapping on the wood preservative. I started out with what I presume was a water based product, Cuprinol Ultimate. But yesterday in Carrick they had more Cuprinol garden wood preservative on special offer so I took away a tin of that as I had just run out of the first. Second tin is oil based it seems, so I am slapping on oil based over water based. Sod it, I don't care. I'm just drenching the timber and it seems to be adhering well. My god, painting those beams - especially the undersides is a messy job. I have preservative all over the place at this stage.

Anyhow, a picture tells a better story I guess.

When I left you yesterday, I was wondering how to terminate these runners over the door. I went with strapping but it looked awful and there was serious lateral play in the fixing.

So this morning, I undid the strap, put up a ripped down piece of timber with 4 80mm wood screws countersunk 20mm into the wood, with washers.

This allowed me to use strong L brackets. Looks "slightly" better.

The two runners terminated.

Here you can see those same two runners from the other end.

Third small runner installed to the facia amd soffit with L brackets. Not hugely strong, but it has no load to take. It's job is just keep the end of the pvc sheet secure.

Slapping on preservative. Messy messy job, it's as thin as water. It spills and splashes all over the shop. I have basin of hot soapy water and a scrubbing brush ready for when it drips on the walls.

I'll take any help with the ladder I can get.

Katja !!!

Looks brilliant, really great job. You won't know yourself tucked in under there while it's p*****g rain outside

To hell with you rain, hell I say !:D:D

Three things -

What did you do with the light fitting?

Are you still putting up florescent tubing from that outlet?

And a suggestion, if, when you get your boat in, you could possibly use your tarp and pin it to the sides of the structure to prevent wind blown rain in on top of you

ValerieR · 20-09-2011 11:20pm

You will soon need a rocking chair to put under this lean-to ...

Nice job & updates ... Thanks.

Light fitting? oh god yeah. Good man, I totally forgot. I'll have to take it down tomorrow and just terminate the cable to a junction box. I'll go with a fluorescent tube or two.

Re-tarps, way ahead of you:)

Gingersnaps · 21-09-2011 12:15am

Well done. It's looking really good. You won't know yourself when it's finished.:)
