Building a new workshop / lab
« on: August 13, 2012, 10:05:12 pm »
I have been living in my current home for the last 12 or so years. Tucked away at the end of the garden was an abandoned shed. My landlord (Alex) who lives abroad had a great deal of his things stored inside. As we never had the keys for this shed, we never paid much attention to it.
Recently, Alex was in the country and dropped by to collect a couple of his things. Unfortunately, without our knowledge, the roof had gone in many years ago it would seem. About 10% of the roof remained intact and most of the contents has been ruined.
We reached an agreement where I could use the shed provided I made repairs to it and store whatever was still in good shape.
This suits me because my workspace has expanded over the years to the point where some extra space would be most welcome. It may seem crazy of me to invest my own money in someone else's property, but I will save money by not paying for off site storage anymore. My return on investment is about 8 months.

So, lets get set to work.

Quite a mess, it'll only get worse though. Alex put polythene on the roof perhaps in some sort of panic.



Inside is pretty bad and even with no roof, it stinks of rot.









Upon removing the contents I found one of the walls had split from top to bottom. I pretty much pulled the whole wall down and built it up again from the ground. I put steel reinforcing band between each course.









Now it's time to get a new roof on. The entire roof had to be removed as the joists, although in not too bad a shape, were under spec'd. The joists really need to be 50x100mm treated timbers with 600mm centres. I also went for 18mm ply, expensive, but necessary in my opinion.

The old timbers are removed and the floor cleared. I had some much appreciated help from my brother and my friend Chris.



Now we have to get rid of loads of plants that have grown through the roof over the years.







Finally, the timber delivery arrived at 3pm. I had to get the roof on the same day because rain was forecast for the Sunday.

Roof timbers going up fast.







Now the ply goes on top. As a side note, if you ever have a project that involved driving a lot of screws, do yourself a favour and get self drilling Torx head screws. They save a great deal of time. No cam-out at all. My local store stocks a wide variety of the Paslode ones. They are more expensive, but well worth it. A great deal cheaper then buying a Paslode nailer ;)
Note that the correct tongue angle when performing this task is vital :)







Now the boards are screwed down, the surface needs to be swept and prepared for the one piece EPDM rubber roof.



The rubber is laid out and here I am applying the glue.





Just before dark, the roof is complete.



The next day I put up the roof trims and guttering.





So now, it's time to get the inside done.
I applied a liquid DPM (damp proof membrane) but I didn't get on with it much so I put polythene down on top of it. I then put stud work on the walls and floor to hold the insulation in place.



The insulation arrived on time. I went for high performance Celotex PIR insulation boards. 50mm for floor and walls and 75mm for the roof. This stuff is manufactured locally, some of the boards were produced just days before by the date code on them.



It's pretty easy to cut and install.



I used odd planks of wood from the ruined flat packed furniture to make the floor. I just trimmed the rotten ends off of the pine sheets to make a good solid floor.
The floor is mostly complete, just the odd shapes to be cut and screwed in place.



That's my progress so far. The next thing is to put a decent door up.

Mmm, thats a whole lot of white folks in Zimbabwe  ;D
I second the comment on the Torx screws. I switched to those as well and they work way waaay better than Pozidrive or Philips.

I'm missing the electricty in your 'lab to be'. Wouldn't it be easier to get the feeding cable in before adding the walls? And how about air conditioning?

That in the housing industry is called a "unique fixer-upper opportunity"!

12 years is a long time to be renting in the one place. What's the housing market like in Zimbabwe? can you get a foothold on your own place?

Kibi may be a Whenwe, but he is an expat ( like most of the population) living in the UK. It does not get that cold in Zim that you need insulation, rather you would thatch a shed roof as insulation, and you would use natural round wood trunks as the framing. Or you use a lot more slope and a sheet metal roof because it rains a lot, heavy rain and a lot of it, then the dry season.

Torx screws are king, they don't slip like Philips! And the bit size is go nogo. Perfect match for powered tools.

Kibi, that garden needs a serious workover. Brushcutters, pangas and a truck to take it all away. You can film an episode of The Jungle Book in there.........

Oh yes, I am from Zimbabwe, but I have been living in England for the past 12 years or so.

Ja, this is a problem. It's the reason that the power cable is not in yet. It's going to be a lot of hard work clearing all that away. The thing is, certain things must be done whilst it is still summer, other things can be done even if it's raining.

After twelve years I'd have thought you might have noticed that a British summer mainly consists of rain, too ;)

Living in the UK it's difficult to get on the ladder even with a good income and sensible savings.
The housing market in Zim is a bit different though. The last I heard was that the seller could keep the first US$50,000 of the sale and the reserve bank would "look after" the rest for you. This doesn't leave much incentive for people to sell their US$1M properties. Some of my relatives just managed to sell their property before the new law came into effect.

Ya sure ... where i live is much worse
Living in a house similar to mr jones's house will cost a few million.
AAND you are bounded to a 99 year lease, probably 30 years left if it went for 1M

At least you have a lease and legal recourse. Zim is all political abuse and expropriation without compensation.

I have made a little bit more progress.

I've got a much better door on now. It still needs to be insulated, but I'll do that once the latch and maglock are fitted.



I've also got the sub-floor complete and most of the plasterboards up. Oh yes, I also cursed each and every one of those Phillips head plasterboard screws, every single one cam'd out unless a metric kiloton of pressure was applied to the back of the driver. Rubbish screws, worst invention ever.
Please excuse the noise on the below picture, I quickly took these photos with a telephone.

How much room will you have left for your stuff once all the landlords gear is put back?
It seems quite small to start with.

Better screws! Of course you will find frequent stripping of screws if you use China's screws  ::)
Screw them i'll say!

Most of the old kit is still there, now forming the floor and roof. Remember 90% was tossed due to damage.

It is reasonably big. Nothing is square there, so the small end is about 2.5m wide, the wide end is over 3m wide and it's 4.5m long.
I have re-thunk things and the landlords stuff can go safely elsewhere, so more space for me :)

Never had a problem. Get better bits? ;)

I was using the bit with a depth stop for plasterboards, probably not the best quality. My regular Bosch bits may have been better. Never mind, not much more plaster boarding to do now.
I have been very spoiled by the torx screws though, such a pleasure to use.

I hope to get the power in this weekend and hopefully the singlemode fibre in next week. I'll have to see how things go.

Yeah, those cheap ones suck. Either a normal, good quality bit, or a proper screwgun. Torx screws are very nice, the only problem with them is the complete inability to drive them from an angle.

Get bits with a diamond coating they don't slip and last ten times as long, Most plasterers use them these days as do chippies, if you go to builders merchants you will find that the plain bits are sold in boxes of ten's and hundreds to tradesmen as they get thrown due to wear frequently, especially high wear rates on the bits with the modern hardened screws.

So, finally there is some power in. Not very much power because I still need to get the rest of the RCBO's.
I dug a trench for the power cable and put the earth rod down.

Here is the 1.2 metre earth rod smashed in and a 10mm cable attached.





Then, as SeanB suggested, the clamp is covered with grease, a finger from a rubber glove goes over that and then self amalgamating tape over the lot. This prevents corrosion.



Now, if there are any Health and Safety police about, please do take the day off. I am well aware that my board looks poorly installed, but is not complete by any stretch of the imagination. It is working for now, it is providing protection and has only got to run a lamp for the moment.
I plan to mount the Consumer Unit on a hinged board to that I can bring the cables in and out from behind it. This also makes it easier to perform modifications in the future.
All it has now are a 100A incomer and a 6A RCBO. The incomer is what was supplied with the Consumer Unit, the cable is protected appropriately at the head end.

When people talk about building their labs they usually look to put test gear on a bench, not starting with the housing for the lab, or even getting AC power lines from the company!  This thread is a first.  A large amount of work, and very good job.   At least you have an opportunity to design pretty much anything you'd like to make it most ergonomic.  Please keep posting photos, this is like watching "This Old House" for EE folks.

I managed to recover sufficiently from my hangover today to put the worktops on.
The work cannot be completed today because my saw blade is dull.

Circular saw? or Jigsaw? I was looking to build a wooden bench too as an extension of my current bench

Circular saw is laying on its side on the table. I assume that is the blade he is talking about.  Some of the particle board fillers of those table tops can be very abrasive, killing a non carbide blade very quickly.
