The spaceframe chassis during clean and paint

well designed and constructed. Very good workmanship

Adjustable gas shocks from Mini specialist

The Vauxhall suspension is well designed and effective

The Vauxhall suspension has some advantages over MG Midget

Taking the body off has allowed me to remove the Vauxhall Viva engine and gearbox.  These are now sold to a vauxhall enthusiast, and a 1380cc MG Midget engine and gearbox has been purchased as a replacement.  … In fact I have obtained 2 engines.  One is a very good, used 1275cc, mildly tuned to give about 90bhp, the other a much more highly developed, fully rebuilt 1389cc unit that will give 120 – 130bhp. … I will put the 90bhp engine in whilst testing and tuning all chassis components.  Then switch to the more highly developed engine once the testing period elapses.

I have carefully examined the front suspension system, and decided that there is no advantage in switching to MG Midget suspension components.  The 60`s Vauxhall system was used in many specials and kit cars back in the day, and has some advantages over the midget arrangement. … It has fully triangulated top wishbone arms, whilst the midget uses the single arm of the lever arm shock absorbers.  The Vauxhall set-up also carries a telescopic shocker, which I have been able to uprate to adjustable gas units from a mini.

Having removed the Vauxhall engine and gearbox I have to consider what to do about clutch operating systems.  The Vauxhall is a cable operated clutch, whereas the Midget is a hydraulic system. … I`m hoping that I can use a midget pedal, master cylinder and slave cylinder, whilst retaining the Vauxhall brake pedal, master cylinder, etc.  … Havn`t got to that job yet, but will post some info when I do.

Anyway, I don`t know why I did it, but I spotted a rather vintage looking hillclimb special for sale, and bought it.  .. I think I must have been seduced by the rather nice looking aluminium body.  I thought  I might use the body on a much modified Riley nine chassis, give it a early Riley nine mag engine, (I`ve got a rebuilt one sitting in my lock up garage), and turn it into a VSCC racer. … However, looking at it now, and knowing how many other projects I`ve got “waiting in the wings”, I was probably a little hasty!  … But there is always plan B.

The hillclimb special was reputedly built by an aircraft engineer back in the 60`s or 70`s.  It is based on early 60`s Vauxhall Viva running gear, and has a 1200cc Viva engine and manual gearbox. (Possibly the most unexciting engine ever fittd to a race car!).  … Plan B would be to change to MG Midget running gear, and fit a tuned 1275cc A series engine from a Midget.  After all, the A series Midget engine can be tuned to give 120bhp, and the spaceframe chassis is well constructed and light.  … Using pre 65 Midget parts would mean that it would qualify for pre 65 races, sprints and hillclimbs, and there are many events that include a class for pre 65 sports and racing cars.  … And of course, the parts are more readily available, and the project is much easier.

Have a look at the pics and see what you think.  … Suggestions and ideas are very welcome.

Well built and nice looking

Not sure about the Vauxhall Viva runnin gear

Why did I do it?

Possibly the most unexciting engine ever fitted to a racer!

I have always been interested in blues music.  It probably started with the blues bands that became popular in the early 1960`s.  The Rolling Stones, John Mayals Bluesbreakers, (with Eric Clapton), Jimmy Hendrix, Fleetwood Mac, etc.  … Having messed around playing bits of bottleneck, (slide), guitar for a while now, I was thrilled to see Seasick Steve on TV playing bottleneck on 3 string instruments.  … Looking into his style I soon became aware of a internet site at www.cigarboxnation.com, (check it out), and began learning more about these fascinating instruments.

Before long I was making these instruments from material found around my garage, (probably explains why the Riley isn`t progressing so well!). … I`ve abandoned the standard 6 string guitar now, and I`m playing 3 and 4 string, home made cbg`s.  I get a huge buzz from playing music on an instrument I made myself from mainly reclaimed material!

The concept is to mimic the American negro slaves of the 1920`s and 30`s in making musical instruments from material to be found lying around, using only hand tools, in a back shed type setting.  Cigar boxes were a commodity to be found around wealthy households in America, just as oil cans were to be found in Africa.  (See the pic of my oil can guitar).  … Playing these instruments by sliding the neck of a wine bottle on the strings produces a “dirty” blues sound reminicent of Delta or mississippi blues.  Put it through a crude amp and you`ve got a Chicago sound.  .. Whats not to like!!

A cbg with just one string is a diddly bow.  Thats where Boe Diddly got his name. … My playing is pretty crude and the songs I can play tend to be simple and repetitive.  (I think it was Woody Guthrie that said, “anyone using more than 3 chords is showing off”).  Well, I have little natural talent for playing, and certainly can`t show off!  … My current play list is, “Baby Please Don`t Go”,  “Sittin on Top of the World”,  “You`ve Got to Move”, “Nobodys Fault but Mine”.  I`m working on “Rollin n Tumblin blues”,  and “Smokestack Lightnin” .  … All of these are taught on Keni Lee Burgess tuition CD`s.  Look him up, he`s brilliant.

I`ve had great difficulty convincing my freinds cbg`s are cool.  However, I found a picture of Johnny Depp carrying a cbg through an airport somewhere, and they`ve finally stopped laughing!  (See my pics).

My collection of cbg`s

One of my favourites

Look who it is! (The only thing I have in common with JP is a cbg).

 I sold my MG competition car, (turned into a bit of a disaster), and switched to a highly modified 1964 example for next seasons sprins and hillclimbs.  More of this later.

Anyway, the Riley special.  I have been working on the braking system, (particularly the handbrake), floorboards, pedal boards, torque tube cover, aluminium panels around the bulkhead firewall, and many other minor jobs. … I havn`t got pictures to post just now, but I`II take some over the next couple of days.

The floorboards have been cut from marine ply and mounted on aluminium brackets and the rebates cut into the bed timbers of the body frame. … This has taken weeks and weeks of making patterns, designing and constructing brackets, etc.  The footboards which are cut around the pedal assembly were particularly complicated and difficult.  They also required aluminium facing as they form part of the firewall between engine bay and cockpit.

Whilst making floor boards I decided to complete the rear brake linkages and design a handbrake assembly.  This would be more difficult once the boards were in place.  The handbrake assemblt is from a early MG Midget. … A nicely made handle and rachet assembly, connected by a standard cable to newly designed and constructed brackets on the brake actuating rod to the rear brakes.  (Something else that took weeks!).  … Pictures later.

About the 64 MG Midget race car.  As I have said previously, I enjoy the MGCC sprint and Hillclimb series, The Luffield Speed Championship.  .. The MGCC Luffield Speed series goes to Prescott, Shelsley Walsh, Loton Park, Anglesey, Goodwood, Silverstone and many other great venues.   The car I have bought for next year is a ex circuit racer that competed in the Midget Challenge race series.  It is a serious competition car with the followin spec:

Ready for 2011 season

Languishing in my lock up

The coachwork is worse than it looks!

recently rebuilt engine. good spec

Nice twin SU set up

For two or three months now I seem to have done lots and lots of small jobs that are not visible when you look at the car but are an important part of the project. (Fellting and fitting brake linkages, sorting the pedal arrangement so that they can be operated by my size 10`s and don`t foul the bodywork, etc, etc). …. I have spent a lot of time working out how to best fit floorboards, footboard, (around the pedals), brakets to support boards, etc. …. Always being aware that there should be a fireproof barrier between the engine compartment and the driver.

The boards are half inch marine ply covered with 20 gauge aluminium sheet around the bulkhead area. I am undecided whether or not to aluminium cover all of the floorboards. (Many old cars just have ply, painted or varnished against  the elements).

I have also been sorting out carbs and inlet manifold.  I have a pair of one and a quarter inch SU`s, but for the moment have fitted a large single SU on a manifold constructed by the previous owner.  …. I know in the MG sprint/hillclimb series many drivers prefer a single large SU rather than twin SU`s, and they work very well.  Anyway, the single SU will serve to get the car running and sorted.

I will try to blog more regularly now. … I have started cutting aluminium panels ready for shaping and fitting.  More of that later.

modern`ish single SU for the moment

As a result of this pondering I have advertised a 1933 Monaco that was “waiting in the wings” for my attention. … I had thoughts of  building a Brooklands replica at some future date.  … Anyway, the advertisment reads as follows:-

1933 Riley Nine Monaco For Sale		£9,750 ono (approx. €10,741 or $14,540)
1933 Riley 9 Monaco. Good mechanical condition, patinated body and interior. Could be MOT`d and used as it is. Plenty of room for improvement to body, trim, etc. … I bought this car with the intention of using it as a basis for a Brooklands replica, but have had a change of plan. A strong running engine, rebuilt 5000 miles ago, with twin SU`s and reprofiled cams, (twin exhaust profiles). Gearbox, axles, brakes and wheels all good. (Rebuilt powder coated wheels). … Body is fairly scruffy but has had some recent new timbers and all doors close as they should without sagging. …. Lovely Rotax head & sidelamps in great condition. This car was taxed & MOT`d in 2008. A former owner was an official of the Riley Register.  I may also part with a fully rebuilt 12/4 engine and pre select gearbox.  However, I would be looking for about £6,500 for this. …… Alternatively a shortened 9 chassis with rebuilt magneto engine and silent third gearbox.  Chassis restored and painted, torque tube shortened, etc. Also about £6,500   I hope to post something soon about the continuing work on the Riley special.

A good tuned exhaust system makes a huge difference to the way the car “breaths” and gives a very worthwhile improvement in performance. … Particularly when matched to a good pair of SU carbs and cams with hotter than standard profiles.

The manifold is a beatifully made, 4 into 2, into 1 system that curves downwards  quickly enough to sit inside the bonnet. … I got it from a craftsman well known for his skills, but also well known for having a very long waiting list of customers.  I ordered it early in proceedings so as not to be waiting when everything else was done.  Expensive but worth the wait! … I also have had made some special stainless steel manifold nuts. These are 5/16″ BSF threads, but with 1/4 bsf spanner flats to enable fitting into the tight space next to the tubes of the manifold.  They are also much longer than standard nuts.  And new gaskets, of course.

You will see from the photos I have also coated the bodyframe with black, oil based paint to prevent the timbers absorbing moisture. … I notice a lot of vintage car bodyframes are left unprotected and wonder why?

The body is made up of high grade marine ply and a few ash timbers.  The ply has immense strength, is water resistant, and easy to work.  The body has enough curvature to not look “slab sided”, but very few compound curves that would make the aluminium panels difficult to produce. … The pictures show the bodyframe shape but still needing lots of sanding down and finishing off.  I have remade the firewall bulkead that sits behind the engine, (not satisfied with the first attempt), and intend making a battery box to fix between this bulkhead and the scuttle bulkhead that carries the rear edge of the bonnet.

Loton park hillclimb, 5th April 2010 was the first event of the season in The MGCC Luffield speed championship.  My car is a standard roadgoing 1979 1500cc, (rubber bumper) midget. …. I had spent the last couple of weeks fitting a fresh engine and preparing the car for the series, (see previous articles).  As it turned out the work took much longer than anticipated and I didn`t finish untill the day before the competition! … This meant no time for a rolling road set-up, and very little time for final tuning and testing.  The ignition timing was done by “sight and sound” and the carbs not touched at all.  Just time for a 2 mile test drive around the block, check nothing had fallen off and all fluids were still where they should be.

Scrutineering was fine.  … Battery strapped down, extra springs on the carbs, no holes in the bulkhead firewall, fire extinguisher fitted, helmet, overalls, gloves all conforming to recent regulation updates. (etc, etc). … Loton park is a lovely hill.  About 1 mile long with left and right twists and turns, a long sweeping section that can be taken flat, it even has a downhill section!

My target time was 70 seconds.  My first practice run was a very conservative 82 seconds, limiting the revs to 5000 and watching the oil pressure gauge for signs of oil surge away from the pump pick-up. … Satisfied that all was well, my second run was 79 seconds, using 6000 rpm and carrying more speed into the corners. ….. The first timed run was 78 seconds.  I don`t have a time for my final run. (I will add it later).  A satisfactory start to the season considering there is more setting up to do on the car yet.

Scoring in the Luffield champs is a calculation of time achieved, measured against the target time.  Assuming my best time was 78 seconds and the target was 70 seconds, I guess I scored something just short of 90%. …. I`m satisfied with that for the moment. I hope to get some scores better than 95% later in the season. ….. The pictures show the car in the paddock and in the assembly area at the top of the hill, waiting to return to the paddock.

I started by removing all auxillary items that either, attach the engine to the chassis, add weight, or are liable to get damaged as the engine is lifted out. … Starter, alternator, carbs, exhaust, fan, earth lead, throttle cable, choke cable, various wiring connections, distributor, cap, leads, etc, etc. … Then removed radiator and all hoses, plus expansion tank. Drained the oil and water, of course. … I also removed front bumper, grill and various other front end components. (Partly to facilitate fitting an oil cooler while the engine was out). … I had Bens assistance in drawing the engine forward untill clear of the gearbox and lifting out with the use of lifting tackle attached to the steel girder across the roof of my garage. … I dare say that this dosn`t sound too difficult but I have the skinned knuckles to prove otherwise!  Anyway, with some grunting, sweating and swearing, the old engine was on the garage floor.  …………… Incidently, I decided to leave the gearbox in place because I saw no sense in changing a gearbox I knew to be good, for one that was unproven.

With the engine out I took the opportunity to thoroughly clean the engine bay and waxoil all of those vunerable corners that trap dirt/damp and allow rust to develop. … I also located the best place for the new oil cooler, where it would get good airflow but not impede airflow to the radiator and engine bay. …. I know that dosn`t sound much but it consumed almost 2 full days!

Lifting the new engine in was not particularly arduous, but not simple either.  Getting everything at the right angle for the engine and gearbox to marry together was fiddly and time consuming, but eventually they slid into place and bellhousing bolts were fitted, (more knuckle damage, but Bens knuckles this time!). … Just the auxilleries to fit, along with cables to replace, wiring to reconnect, ignition timing to set, etc, etc, etc! .. I won`t go into detail but lots more time consumed and more knuckle damage.

A difficult part of this engine change was fitting the new 4 into 2  into 1 tubular exhaust manifold.  This manifold will make a big difference to performance. Perhaps the biggest single  improvement of all the changes being made.     ….. It appeared at first that the steering column would need removing whilst the manifold was wrestled into place.  But after much headscratching I discovered that removing the studs that hold carbs and manifold against the cylinder head allowed the manifold to be slid into place.  Replacing the studs and then fitting the nuts washers achieved satisfactory fitment. …. Just the alterations under the car to get the manifold to meet the long exhaust pipe running to the rear of the car left. (About another half day of work!).

An integral part of this engine change was to fit a oil pressure gauge to supplement the dashboard warning light. … Also to add a voltmeter, battery cut-out switch, and a starter button that will allow the engine to be turned without the ignition on. (To circulate oil after periods of standing which allow oil to drain from bearing surfaces resulting in rapid wear on start up).  … This along with the baffled sump that will prevent oil surge away from the oilpump pick-up will result in bearings staying good even on an engine driven hard in competition.

At the time of writing the engine is ready for start up, but hasn`t yet got the cooling system in place. … New kevlar competition hoses arriving tomorrow.  … I doubt if I will achieve a rolling road set up before the first hillclimb, which is Loton Park in a weeks time.  I will set the ignition timing as best I can get it and tune the carbs to the best of my ability and cross my fingers. …… Rolling road set up will be done later.
