• Hi all and welcome to TheWoodHaven2 brought into the 21st Century, kicking and screaming! We all have Alasdair to thank for the vast bulk of the heavy lifting to get us here, no more so than me because he's taken away a huge burden of responsibility from my shoulders and brought us to this new shiny home, with all your previous content (hopefully) still intact! Please peruse and feed back. There is still plenty to do, like changing the colour scheme, adding the banner graphic, tweaking the odd setting here and there so I have added a new thread in the 'Technical Issues, Bugs and Feature Requests' forum for you to add any issues you find, any missing settings or just anything you'd like to see added/removed from the feature set that Xenforo offers. We will get to everything over the coming weeks so please be patient, but add anything at all to the thread I mention above and we promise to get to them over the next few days/weeks/months. In the meantime, please enjoy!

Small workshop

A duo-pitch roof is more attractive visually, and generally gives you more headroom. The mono-pitch or flat roof is (marginally) cheaper, and easier to build. Whichever of those factors is more important to you, that's your answer.
 
Thanks Mike I think I will be happier with a double pitch I have not worked it out but could I have the centre at 2.5 m and the edges at 2.4 m it is going to have the edpm roof.
As I have already blown the budget I might as well build what I want.

Ok I have made a decision the supplier has told me they only stock concrete lintels in 1.2 and 1.8 m so my workshop is going to be 2.4m x 3.6m as per my original plan.
I am also going to use mineral wool for the insulation.
If my joists are 150 mm and the insulation is 100 mm what supports the insulation and does that prevent mice from moving in.
Thanks
Michael

Don't forget to allow for the corners in the overall dimensions.
Possibly going to be 2.6 x 3.6 or 2.4 x 3.8 or 2.5 x 3.7

Sorry Bob I don't know how I missed your post I did work this out but not until yesterday. :D I am going to add the extra to the length. My wife and I are actively discussing the width of the workshop.the distance between the fence and the steps of the decking is slightly less than than the current width of the shed including the 1 m from the boundry. She has been pointing out that all of our neighbours have sheds right on the boundry.
If it ever stops raining I am going to lay out some deck boards so I can see the actual size in place.

If my pictures never show the fence side of my workshop. Keep it to yourselves ;)
 
Just as forecast no rain until after dark I did not stop until the light had gone. So no pictures I managed to dig one long side and the back as I was concerned about rain I filled each trench as it was finished.
I think I may have ordered the wrong filling material I intended to order mot 1 but instead I have ordered some smaller stones in sand but they have compacted really well. No room for a wheel barrow so it was builders tubs all day.
Rain from now until Friday.
 
Hi everyone I may have mentioned I have some issues with my right hand and nerve damage..
Over the last few years I have developed some tendon issues which have required surgery the next one was planned for January I saw the consultant this morning as I was in a lot of pain which was agrivating my whole arm.
He had a small gap in his list tomorrow so I am booked in 12 noon.
So there will be a pause in my construction plans but it will give me time To re read all of the apex rooves as that is my new plan. I may even try to learn sketch up.
I should be able to use it in a few weeks once the stitches are out but have to return to high level Medes for some time until the nerves settle so no power tools allowed. On the bright side my back will have a chance to heal :D

Good luck with your procedure!

Bob
 
Yup...all the best, Michael. If you are serious about getting to grip with SketchUp then I heartily recommend the DVD from one DaveR of this parish. There are some free websites that claim to be 'for woodworkers' but they teach you bad practice.
 
I wish you speedy recovery.

The DVD by DaveR is great, I go back to it on a regular basis. I bought it as a download which means no waiting for the postal service and no import duty

Any idea of how big the download file is?

Sorry, no idea. If you're bandwidth constrained then there is always the DVD
 
Hope your hand gets batter soon and that you do nort end up working outdoors in the worst of the winter weather.
 
That arrow reminds me of my mate's when he had his op on his left leg. He got his wife to write in indelible ink on the right leg...'Not this one, the OTHER One'.

It is scary though. When I had my second cataract operation (right eye this time) just before I went into theatre I went through the formal consent process with one of the nurses. "OK...let's see..you're down for a cataract operation on your left eye". :o
 
Oh yes, I had big arrows on my leg when they were operating to stabilise the lose bit of bone which I'd broken of the tibia.

All these arrows, but where are the cowboys?!!

Not working in the NHS thats for sure! Excellent people.

SWMBO has had 20 significant operations on toes, ankles knees, fingers wrists shoulder and eyes each time they have added the arrows and about half the time (I think) deliberately run through the consent form saying the wrong side. I think is is an attempt at humour and making sure the patient is paying attention.
Her last job was to fuse the top 5 section of her spine. That had no left-right ambiguity and so the only job so far not to get arrows.
I keep telling here she is worth her weight in scrap titanium but she just gives me strange looks :lol:

Bob
 
Thanks I am pretty sure my right hand must be into double figures for surgery over the years and although my life changing accident occurred during surgery. Causing some legal issues which took 5 years to sort I bear them no ill will. I have done some work with this hospital in recent years.

Hey look what showed up today.

At least once I am ready my hands will be warm and dry. My stitches are due out in 10 days the surgeon told me I could take them out myself and he added a blue stitch at the end of his modified blanket stitch. So I would know which one to cut if they were causing me irritation.
That's why he wears one of my hand made leather belts :D
 
Hope the healing process goes well.

I’ve got three permanent markers - tiny tattoos used as aiming points for radiotherapy.
For my major surgery I was marked all over my thighs and stomach by the plastic surgeon indicating possible donor locations.

Rod
 
Rod my surgery is quite minor compared to yours.
The big dressing was causing some issues with my arm today so I removed it the small opsite dressing had curled up inside so I replaced that.
Both sides of the wound are together and all looks really well I have more movement than I have had for many years.
 
Nice to hear it’s healing well.

My big op wasn’t entirely successful so I’m down for a much smaller one - only 2 to 3hrs this time. The last one took 23hrs.
Parts of me to be frozen by a new process of Cryoablation!

Rod
 
Thankfully I am not in that league, I was in and out of theatre within an hour. I hope your upcoming surgery goes well.
 
I am trying to get my head around what is required for a double apex roof I am in the process of re reading threads to gather as much information as possible.
I have made a rough drawing to assist with ordering I think it will be the new year before I place my timber order now. But this should allow me enough time to get my planning right before I start.

2018-12-06_02-22-56 by my0771, on Flickr

I will work out the detail of the roof as my plans progress my aim being to get as much headroom as possible but have a finished product that looks good.
I did manage to get two trenches dug and filled with stone before the heavy rain and my surgery interrupted.
Any input appreciated.
 
Normally such a roof would have joists at wall plate level or partway up pitched rafters and a ridge board.
However with such a very low pitch you might get away with overlapping rafter pairs alone bolted is several place where they meet?

Thanks Bob.
I think I understand that rather than having joists running from wall to wall. Each rafter would go from the wall plate on one side and be bolted to its pair from the wall on the other side.
I plan to use OSB3 11 mm inside and 18 mm under the EDPM.
 
Yes that is what I'm visualising.

Scaling off your drawing it looks like the rafters are inclined by 50-75mm along their length of about 1.3-1.4 m
Putting in a rafter as well would likely mean the top of the rafter would be height than the rafter.
Drawing out a detail section should show the problem.

Several bolts per rafter pair with serrated lock washers in between the rafters should be plenty strong enough and the decking and ceiling OSB should hold the rafter pairs at the rigth spacing making the ridge board redundant.
I'd only suggest this for such a low pitch which gives lots of overlap area in combination with such short rafters for your 2.4 m width.

Bob
 
Hi Sam I have replied.

Thanks Bob
I am sorry I am not sure that I understand do you mean the joist would be redundant as it would take the same space as the rafter. Or am I on the wrong track all together.
I may have to make the rafters longer as I have not allowed for the air gap and outer feather edge boards so to get a 150 mm overhang.
Thanks
Michael
 
The fact that the over hang carries no weight makes things clearer to me I was having difficulty working out that junction. How deep should the opening (birdsmouth) be in the rafter was a question I was going to ask but if that is where the weight is transferred then I guess it will be the dimension of the wall plate.
Allowing maximum contact and weight transfer.
I am trying to find drawings I have previously seen showing this type of roof detail.
Thanks your help is appreciated :)
 
Thanks Roger that explains a lot. Although its minimum angle is 3 degrees with a 209 mm fall from ridge to wall. Should I consider revising my plan or will a 100mm fall be sufficient ?
I understand the junction of the rafter and the wall plate much better now.

Afraid I can't really advise on that...not my area of expertise.

I'm going to disagree with Bob here for about the first time in history. The outward forces on the wall plates from a roof at such a low pitch are great than from a roof with a steeper pitch. The idea of just making a strong junction at the ridge simply isn't good enough, I'm afraid. (I'll also add that toothed connectors are a really bad idea, and can actually weaken a joint, rather than strengthen it......but that's just an aside).

Having said that, there are a couple of simple solutions. Either put in a structural ridge, and with a 3.6m long workshop that could be just a 150x50, or put in one or two ties. These don't have to be in the form of bits of wood, and they don't have to be at wall plate level, but can be up to one third of the way up the rafters. You could use fencing wire and a cheap turnbuckle, for instance, or a piece of universal banding. There is another way, too, which is to have a really beefy wall plate and corner plates to resist the outward thrust of the roof, but that is probably the least practical option.

If it were me, working with that section, I would simply put in a 6x2 ridge beam.
