Understeer is when you hit the wall with the front of the car. Oversteer is when you hit the wall with the rear of the car. Horsepower is how fast you hit the wall. Torque is how far you take the wall with you ... Or ramblings on three originally Dutch TR7's (a 1976 FHC, a 1980 DHC and a 1981 Sprint powered FHC), including the work done to them and their (ab)use all over Europe. With some of my other passions thrown in from time to time ...

New wheel centres for the DHC
Those that
follow this blog will remember that well over a year ago, I fitted a set of
refurbished Wolfrace Turbo's to my DHC. Because they came with only one wheel
centre I decided to have a set of those made. At the time I contacted a few
local companies who specialise in 3D printing, but they all were far too
expensive or just not interested. So I opted to have them
spun from aluminium alloy instead. Sadly the guy who would do the work suffered from a heart attack and as a result he had to stop with work.
So to fill
the gap till I found a solution I fitted a set from Compomotive, shown above.
But they really are only a stop gap solution as they are a fair bit too small,
but so far the gaffer tape bodge has kept them in place. So it was pretty easy
to forget that I had to finish this little project ...
Until
recently that is, when I was given the details of i.materialise, a company in Belgium who
specialise in 3D printing. So the AutoCad file I created over a year ago was
dusted off and converted to a 3D printing format. That turned out to be not as easy as I thought, as one of their support engineers pointed me to the fact that the model I
sent over was rather rough. But with some help from a friend who knows more
about AutoCad then me, the file was converted to a much higher resolution 3D
printing file. The end result should look something like this ...

FHC resto nr. 26; Swage line rectification
Paint
preparations have been on hold the past few weeks due to illness. But by the
end of last week the work has restarted. First on the to-do-list was rectifying
the swage line on the right hand rear wing. As a result of the numerous small
and not so small dents in this area the line had suffered a bit. Which is
clearly visible in the picture posted on November the 9th. After adding some
filler and sanding it down it now looks like this ...
Also did
some adhesion tests to see how the primer attaches to the epoxy primer. I
mentioned earlier that we had some doubts here, but I am glad to report all is
fine. These test were done on the engine bay, which is also finished by now ...

Alloy SU mounts part 2
Or how the
transformation from digital file to machined parts looks like. Friday evening
there was a fairly large box waiting for me at home. Sure it came from
Schaeffer, and nicely within their estimated delivery window. The only thing
that struck me as odd was the box's size. It really was vast for what it should
contain ...
For
comparison I put an original carburettor mount on top of it together with the bolts needed to finish
them. So did I make a mistake with the files, or did something go wrong on-line? Or did they just run out of smaller boxes? But a quick inspection of the
contents showed me all looked fine.
This was confirmed
after removing the parts from their protective wrapping ...
... and
comparing them with an original mounting block. This was a bit of a tense
moment as there is always some doubt in the back of my head ... "did I measure everything correctly".
But I needn't have worried there as everything fits as it should and all holes
align correctly ...
And as an added bonus these alloy mounts are each 40
grams lighter in comparison to the original rubber ones. See how they behave on
the car, and in particular how they influence heat transfer to the carburettors.
Well, the first little winter project is finished. Getting cool air into the
carburettors is one of the other jobs for this winter. To be continued.

Calendar Girls 2015
With the
end of the year approaching it is time to start to think ahead to 2015. What
will the new year bring to us personally and at work. It also means making
plans for holidays, trips abroad and the TR7's. And time for a new
calendar to grace the study wall. This year I decided to use pictures of my
TR7's, taken over the past years across Europe.

Alloy SU carburettor mounts
With both my TR7's officially of
the road it is time to start on some typical winter jobs. First job I will be
tackling are the rubber carburettor mounts with which the SU's are mounted to
the manifold on the DHC. British Leyland decided it would be a good idea to use
rubber mounts, as they act as heat insulators and vibration dampers. When they are new they
probably do their job quite well, but after well over 30 years even the best
original mounts will be well past their prime. Not to mention the very poor
quality of the aftermarket items. When I restored the DHC I thought it a good
idea to extend the life of the original mounts as long as possible, by
supporting them with some heavy duty cable ties. Clearly visible in this
picture ...
To start the winter jobs, this weekend I dusted of the AutoCad file I created almost three years ago, to record the various dimensions of the original mounts.
To start the winter jobs, this weekend I dusted of the AutoCad file I created almost three years ago, to record the various dimensions of the original mounts.
The original plan was to
find a local workshop to fabricate this from alloy. But the biggest problem
here is that it sometimes takes ages before the items are ready. And that is
when I was reminded of the fact that Schaeffer
AG (the
switch panel company) can work aluminium up to 10 millimetres thick. After
a final dimension check against an original mount I redesigned the mount.
This way it can be fed into the
design software as provided by Schaeffer AG. I went for a 6 mm base plate with four
recessed holes to fit countersunk M8 Allen head bolts.
Against which a 10 mm spacer is
fitted. This part has four threaded holes (with M8 threads), enabling the two
parts to be screwed together and preventing the bolts from tuning when fitting
the carburettors. Giving a total thickness which is exactly the same as the
original mounts.
As there are probably cheaper options available I will first do some more checks before hitting the 'order" button. Also finding some countersunk M8 x 45 mm Allen head bolts with the correct (DIN) head dimensions has to be done before the order is placed, as the dimensions are crucial. Something to sort the coming week.

Club Triumph's 2014 RBRR
Finally got round to
finish the pictures I took during last month's Round Britain Reliability Run.
This time with a three man team in a Dolomite 1850 (that really should read
2000 as it is fitted with a TR7 engine).
Team #100 waiting for
the ferry in Dunkirk ...
The usual action at
the Plough ...
Signing in at the
Plough ...
With the stickers fitted to the car we are ready for the start, but that was still a few hours away.
Even the press were present ...
Waiting for the start

The briefing, wonder
why they invented loudhailers ...

Control #2, frantic
action at Blyth Services ...
Just before
approaching the second control stop (and Scotland) the heavens opened up in a
big way. Approaching the Edinburgh bypass, and clearly the weather conditions
still were rather wet ...
Motorway Services
just after the Edinburgh stop. Still wet

But by the time we
reached Skiach Services and the fourth control the weather had cleared ...

After Pimperne the
car's engine started to misfire ever more badly...
But we managed to
limp to control #18 and eventually back to the Plough in time to get the last
signature. For me it was the fifth finish in this event, but have to do it in
one of my own cars yet ...
Teams #93 and #100 on
the ferry, going home ...
