"I

Says John Day, regular contributer to enjoying
MG magazine
Now that Ratty is finished I thought that it might be interesting
to follow up the restoration story with an article about the workshop
where much of Ratty was created and an introduction to some of the
tools I found useful during the three-year restoration.
I took early retirement nearly four years ago after a career in
engineering and decided to fulfil my long-standing ambition to build
a workshop, which would support my interest in MGs. At this stage
I did not have an ongoing rebuild and our garage was home to my
three working MGs and our modern car. If I needed to make or repair
anything I used a bench. In the corner of the garage but I found
there was always the risk of damaging the cars when welding or grinding.
In fact on several occasions I actually scratched my wife's car
while working on an old MG. Not to be recommended!
One of the major obstacles to building a workshop in our garden
was the limited access via a narrow passage at one side of the house.
It was clear right from the start that the simplest solution to
this problem was to use a prefabricated building. I decided to talk
to the Council Planning Office before making any decisions and found
the staff very helpful. I was delighted to find that I could erect
a prefabricated wooden building four metres high with a floor area
of up to twenty five percent of the garden area without the need
to obtain planning permission. It would have been nice to make a
permanent structure using bricks and mortar but the cost and difficulty
in accessing the site put this out of the question.
I had for some time
admired the wooden buildings from a company called Passmores
who advertise in Enjoying MG. The quality of the materials
they use is first class and all external timber is treated
with a preservative applied under high pressure in a process
called 'Tanolising'. From my discussions with the sales staff
I discovered that the most cost effective building to suit
my requirements for a workshop was a standard, single car,
wooden garage. These are sold in a range of sizes and I chose
one with a base measuring 3.5 x 5.5 metres. It came as standard
with double doors and a pitched roof just within the planning
limit of 3.9 metres.
I placed the order for the workshop and was given a delivery
date and a drawing defining the dimensions and type of concrete
base that I would be required to provide. It was quite a physical
challenge to dig out such a large base manually to a depth
of a third of a metre. It was even more of a challenge to
set up shuttering which was level and met the exact base dimensions
to within one centimetre on the lengths and two centimetres
across the diagonals! The staff at Passmores explained that
this level of accuracy was needed to ensure that the building
fitted the base and encouraged me to get the dimensions as
close as possible.
The next problem was how to get four cubic metres of Readimix
concrete from the concrete mixer truck in the road to the
corner of the garden some seventy metres away, partly along
a narrow passage. The easiest way was to hire a concrete pump
for the job at a cost of £200. It had been dry for weeks
but the weather decided to break on the morning the concrete
arrived. Neither the mixer driver nor the pump man seemed
to think this was a problem, 'A bit of water will do it good,'
they both agreed. It might have been good for the concrete
but it was not helping me. I was soaked to the skin and covered
from head to toe in concrete. However by the evening I had
managed to level the base and the concrete was left to set. |

Three weeks later Passmores delivered and erected the building.
It was a relief to find that the base was within the required limits
and the building was finished in about five hours. I could now begin
to line the inside walls and ceiling with insulation covered by
8mm plywood. I also laid a fibreboard floor on a layer of 50mm thick
polystyrene. The time spent on this work was a good investment because
even on the coldest winter's day the workshop is very snug and a
small electric heater is all that is required to maintain a comfortable
working temperature. A lucky find of a dehumidifier for £10
at a local Car Boot Sale meant that the workshop was now warm and
dry.
The next job was to organise a power supply and I talked to a local
electrician about my options. He recommended that an armoured cable
should be run directly from the house consumer unit underground
to the workshop He supplied the materials which included the cable,
a small consumer unit to be fitted in the workshop and all the sockets,
switches and light fittings. I carried out the installation and
the electrician checked my work before making the connection to
the power supply. By using my labour it was possible to keep the
cost down and I learnt a lot about domestic electrics.
I
have constructed several workbenches and been surprised how difficult
it is to achieve the right design. On each previous attempt they
have been too high, too low or not big enough. For my new workshop
I wanted to create the ideal bench and you can see my efforts in
the photographs. Some people would argue that a bench for general
engineering and metal work would be constructed from steel but I
feel a wooden top is kinder to precision surfaces and timber is
nicer to live with than steel. One vital piece of bench-mounted
equipment for me is an engineer's vice and the final height of the
bench was dictated by the most comfortable working height at the
vice. It was useful to provide a decent overhang along the front
of the bench top to allow sheet steel to be securely clamped. I
decided to build an L shaped bench to allow extra space for spreading
out parts when dismantling larger objects like a gearbox.
Another
of my ambitions was to own an engineering lathe and as soon as I
retired I began looking for something I could afford. New lathes
are available for about £500 upwards but these are intended
for the model engineer. I was hoping to find something a bit more
substantial and more able to cope with light automobile machining.
There are a number of manufacturers to choose from including Myford,
Colchester and Boxford so I kept my eyes open at the local auction
house, in the Exchange and Mart and in the Classified Adverts of
the free papers. Eventually I bought a second-hand Boxford lathe
for £500 that had seen only light duties in a small engineering
company. It is a small scale engineer's lathe with a long bed that
can accommodate lengthy parts like half shafts and has proved to
be an excellent investment that has already paid for itself many
times over.
Car
body repairs require sheet metal working tools and the first item
on my list was a good quality Mig welder. The welder I purchased
has a current rating of 30 to 180 Amps, is fan cooled for continuous
operation and intended for use with an inert gas such as carbon
dioxide or carbon. Both gases give scale free welds although carbon
is more expensive. I was going to use the welder with the large
gas cylinders available on hire but in the end I found the small
gas cylinders supplied by local car accessory shops perfectly acceptable
and cost effective. It took me nearly a year to complete the body
repairs to Ratty and a lot of welding but I only used eight of these
small cylinders. The cost was the same as I purchased the very useful
tool trolley shown in the photos to move the welder around the workshop
and this has an upper tray for storing the various sheet metal cutters,
clamps, and hand tools I used as the work progressed.
One
of the best tools I found for cutting sheet metal was the hand nibbler.
I mentioned this in the Ratty rebuild articles and I found it easier
to use than the type powered with an electric drill. The best tool
for clamping two parts together when seam welding is also shown
in the photos. Both were purchased from Frosts catalogue, were relatively
inexpensive and work brilliantly. Next article I hope to cover in
detail how I use the Mig welder, nibbler and clamps to achieve seam
welds. In writing this article I was hoping to provide an insight
into setting up a home workshop suitable for all types of car restorers.
There is no doubt in my mind that my workshop was a major factor
in being able to complete the Ratty Project. From start to finish
it took me about three months to set up and was ready for use at
about the time I discovered Ratty. It is not an exaggeration to
say that without the extra space and facilities I could not have
contemplated taking on such a derelict car.
