      I live in Los Angeles, it doesn't rain much here. or snow, for that matter.
      In 1970 I bought my first car, an Austin-Healy 3000. I was 16 and didn't know English cars had a bad reputation. I learned a lot from that car.
      There were various connectors in the body wiring harness that would come apart and various lights stopped working. I found the connector and put a little RTV on it . Those problems went away.
      I washed the engine with degreaser and a garden hose and it didn't start for a while. I went to the hardware store and bought a can of clear plastic protective spray and sprayed my whole ignition system, plug wires, distributor cap, etc.
      My car was the most reliable of all my friends with their Chevy and Ford cars.
      I never had any more electrical problems.
      Not sure if I still have any Whitworth tools :)

    What a great video, so well made and fascinating narrative. Your production should last through the ages. One small point. When you mentioned the Bonneville style engine you showed a picture of what appeared to be a Triumph Saint rather than a Bonneville. I owned a 1968 Bonneville from new but rode Triumph Saints as a London Met speed cop in the early '70s so I am familiar with both. Amazing machines. I smiled at your review of Whitworth sizing. I had a complete set of Whitworth sockets all my life and don't recall ever using them.

      @@paulbrodie There were two versions of the 650cc Triumph with the Bonneville having two carbs and the Trophy having one. The Trophy was used as a police motorcycle. The police version had a single seat (as in your picture) and I understand the first two gear ratios were changed to provide even greater acceleration. With those changes the police bike was known as the Triumph Saint. It was a very fast, fun motorcycle to ride. I remember when I rode them the fastest and oldest bike in our fleet was a 1967 Saint with a single leading shoe front brake. Later versions had much more effective twin leading shoe front brakes. I always thought it banal that the fastest bike we had was the hardest to stop.

    As a 1st year apprentice I was encouraged, by the motorcycle mad machine shop tradesmen whom I worked with, to buy a Triumph Tiger T110, which was as old as me and deemed rebuildable.
    And rebuild it we did although it was more like "grandpa's old axe", which I'm sure you know what that means, by the time we had it completed.
    I learned a lot from them all and am forever in their debt for it.
    We finished it on a Friday afternoon and on its first speed run, on the Saturday, I sadly confused which side the foot brake was on, having ridden Japanese bikes until that day.
    Bike, meet fence .... at >40 mph.
    Back to the machine shop it went for another rebuild and was sold without ever riding it again.
    Your video made me reminisce but also cringe at some of the engineering that was found acceptable by Edward Turner and his crew back in the 1950's.
    As always, thanks to both of you for some great entertainment and education.

    Thank you Paul, great video. I'm in the process of rebuilding a 1959 Tiger cub with my brother in law. It has been very useful for the rebuild we are doing over here in England. After working with the engine, I understand why the British bike industry died. We've used a combination of imperial, Metric and Whitworth spanners/sockets and it is annoying, especially when the Japanese bikes I've worked on, including one from the 70's all use metric.

    Some great memories there.
    I had a BSA C15, its engine was developed from the T20. You could get to the gearbox sprocket a little more easily than on the Cub.
    Separate oils in separate spaces keeps bits of gear teeth out of the engine oil (no real filters on those bikes). My 1992 Yamaha had bits of metal in the oil filter when I changed the oil and filter last week..
    Nice to see your Whitworth sockets were made by Britool. As an apprentice in the 1960s I bought a socket set and spanners all made by Britool when they were British (now French...). They were very good tools. I passed my socket set onto my nephew/God-son ten years ago, but still have some of the spanners.
    Brit bikes used Whit, BSF (British Standard Fine), UNF and UNC, as well as BSC (Brit Standard Cycle) and BA (Brit. Association) threads. Sometimes all on the same machine..
    The “Lucas - Prince of Darkness” thing was from their early trade-slogan, “Lucas - King of the Road”. The Brit m/c industry was not willing to pay properly for their electrical components, so they got crap because they paid crap prices.

      Your comment on the Lucas trade slogan put me in mind of a similar slogan that I've always found funny (was gonna say humorous but I'd have to put a couple more O's in it so you could read it!)-;
      It's been said that the USA and England are two countries separated by a common language.
      That fact along with the typical yank's irreverence have always made me chuckle about the slogan "Triumph - A Breed Apart"
      The common reaction here was "Yep, most of the Triumphs I know of are apart!"

    One problem from new he had was the primary chain case screws coming undone,he tried everything from locktite to
    Drilling and lockwiring,but they still managed to come undone!
    I always think of him when I see a cub nowadays,another triumph he loved was the 55 t100,his friend tony smith had one from new and was a bit of a speed demon on his t100,and was the fastest bike in the village back in the day!

    Great clip Paul. The guys from one of the dirt bike magazines had a cub set up for desert riding. They would be blasting across the desert and for no apparent reason would crash their brains out. It happened several times. Eventually they figured out that the front brake cable was too short. When the forks extended fully it would pull the front brake on and lock the front wheel. I don’t know if it was a stock cable with stock bars. Might be something you want to check before you go leaping over a set of railway tracks.

    I used to own a Tiger Cub here in Australia (with the "fairing" on the back wheel), and when I got it, it had a problem common to many of the other British bikes I owned; someone had not tightened the shift lever enough, and the splines had been stripped, which necessitated drilling a hole in the junction between shaft and lever and inserting a small bolt as a "key". Other than that I never had a problem with it, and my wife rode it for quite a few years, while I rode my AJS.

      Even seen the gear lever tack-welded on. Had to grind down the welds to remove.
      I have resorted to recutting splines with a junior hacksaw, then using a 1mm slitting disc to cut a slice out of the gear lever clamp aperture, to allow more room to clamp up. This is often necessary because the gap butts-up before enough clamping pressure is exerted on the gearchange shaft.

    BSA had their version of a UK learner bike with the Bantam. My father had a BSA Bantam D14/4, this was powered by a 175cc two stroke motor. I learnt to ride on this bike before I was old enough to purchase and ride my own bike on the public roads. When I reached 16 I purchased my first bike a Yamaha FS1E sports moped. Problem was the FS1E had the typical left side mounted gearchange, as opposed to the right hand change that I had become used to on the BSA. To be perfectly honest it only took me a few days to get used to the left hand gearchange. Next bikes were Yamaha RD250A, then a Kawasaki Z650B1 and finally a Honda GL1100 Goldwing. Still have a nice 1983 Honda GL1100 sat in my garage now.

    Paul yes it’s crazy to have to split the engine to change the front sprocket but triumph fitted a largish one and the chain ware is acceptable the biggest I can get on my Ducati 750 GT is 16 teeth and I get about a year out of it. Have a look at the belt final drive bikes and it’s the same large pulleys. I was looking at retrofit as there ware is almost non existent and the width has come down to under an inch. Also with a single loop frame it keeps the package slender the chain line narrow. Wobbels the mad Aussie.

    If you are working on a Triumph Cub, and you adapt metric wrenches, apart from it being a good move to stamp them to show that they are not what they claim to be, you have to call them spanners, the engine speaks proper English.

    That being said, the Cubs were reputed to be one of the few machines that could lose a bottom end whilst still on the showroom floor! Certainly an exaggeration, but maybe not too much of one ... I recall the bottom end conversion by Alpha being the hot ticket for longevity.

Turns out there was a little oil in the holes and as I tightened the screws which were a tight fit the oil pressure built up until the casting blew off.

    As a schoolboy I was looking to buy a trials bike, I was told to avoid the little cub as it had so many problems. I bought a Greeves (Villiers 250) it ran fine once rebuilt well. I used to run a smaller rear sprocket & shorter chain weekdays & ride it to work. Weekend trials time I'd swap back. Transmission was much tougher than the cub as the welding shows. Greeves were among the best 2T in competition until Husqvarna entered scrambles & Bultaco in trials. I worked 2 jobs to afford a Bultaco & it transformed my capability. Wish I still had that Sherpa.

    Nice run through of the cub. The earliest version was the terrier, only 150cc so even less stress, still quite delicate though. I was thinking, the sprocket would probably wear out at the same time as the bigend, so the design is fine.

Luckily, she wasn’t hurt, and the chain was the only real casualty.
    They draped it over the bars, pushed it back across the road and into the barn where it sat till I got it in 1995. It’s still as I found it in that barn, and definitely on my list of projects to complete.

    Wow, some memories. I got my first motorcycle in '57, a Zundapp 200cc Challenger and the dealer also sold Triumphs. I met two young chaps riding around a local park; one was on a Zundapp identical to mine, the other on a new Tiger Cub. We went on for several rides together and, of course, a race on the roads eventually ensued one evening. The Cub was the supposed sure bet to be the fastest but I passed him with about 2mph to the good. As I grew into the sport, the weaknesses of Cubs became fodder for much shop talk at the dealers I frequented. The sub dealer I got my Challenger from had a Tiger Cub in his stable that had been a race champion at Daytona - the amount of work done to it was amazing to help it hold together and it was a powerhouse to boot. The cylinder barrel had been turned from billet aluminum and a sleeve pressed in, very conspicuous improvement, so much larger diameter than stock. All sorts of changes had been made to the bottom end, I'm sure was a roller bearing conversion as so many began to get. It was a blistering fast Cub, could walk away from a then new Maico 250 scrambler which was good for about 19 hp - saw that contest myself. But, the Cubs were no match for the later Parilla 200cc "Wildcat" which I was fortunate to race for a dealer friend of mine in N.Y. a few years later.

    Dear Paul, is the damage to the crankcases, due to rear chains braking and coiling upon the gearbox drive sprocket? Or the box was out of oil then POP!
    I do not know of any other way that the gearbox could burst open like that! I remember many years ago when I was a marshal for (MAG), I got alone side of
    one of these Cubs doing well over 65mph, and the barrels where glowing, so I told him to slow down a bit before it went BANG!!!
    The 200cc Cub, was a great little engine which did well as a trials bike. Thank You.

      Chris, the damage on those (3) cases was behind the gearbox, not where the drive sprocket is located. I have no idea of the story behind each failure. Thanks for watching!

    Its an early cub with the figure of 8 primary case on the stand, the figure of 8 engines are the most fragile with a timing side bush and a plain big end, Bantam Cubs had the strongest engine, with a better oil pump, a crank supported in better bearings and a roller bearing big end and points on the side. I built a few cubs 30 to 50 years ago, last one sold to pay for a divorce, well it paid the wages of a solicitor for an hour back in Y2K, did you know all solicitors are living proof one of their parents was a rodent? ;=)

    When I worked as service manager at a shop that sold BSA we had a 250 that would run at highway speed for a while and then quit. If it cooled of it would start right up and do it again. The problem was the brass pivot shaft for the points which would expand when hot and keep the points from closing. I have many more stories about British engineering. That said I do have a British friend who is a brilliant engineer. They should have hired him back in the 50’s.

    • @paulbrodie
      @paulbrodie  3 ปีที่แล้ว +1

      Wikipedia said the Cub would quit after 1/2 hour at 50 mph. Same as the BSA. And for the Cub they never figured out why. I figured it had to be electrical... Maybe the pivot shaft too?

    Hi Paul, just a note about the Whitworth sizes you talk about. A 5/16" Whitworth spanner is for a 5/16" bolt or stud diameter - the spanner is not measured across the flats of the nut or bolt head. Makes good sense if you're English :P

    “Sometimes pistons go in backwards”. My first bike was a Honda CB125, I had it honed and a new piston and rings but I put the piston in backwards so it kept on popping head gaskets.. I must have changed that head gasket 5 times. When I sold it, the guy I sold it to overhauled the engine and he said “ hey some idiot put the piston in backawards”!

      My son was given an old 1985 CZ 125-488.0, back when he was 18 as a birthday present. It would only do 45 MPH. My son rode it around for a few weeks like this. On popping the cylinder off, the piston was not only in backwards but it had no rings either. It was only running because that's what CZs do. It would even kickstart, once the crank was spun up to a decent speed. My son is 31 now and still has the bike, now with 38,000 miles on the clock.

    40 years ago I bought a tiger cub with the engine in a box big end gone I rebuilt the engine new big end used it to go to work 2 months later the big ends went again so i sold it with a big end gone. Thing is with British bikes back then whenever there was a British bike for sale it always said recent engine rebuild.

    It's going back about 6 decades for me but as I recall my dad (who was a mechanic, motorbikes, cars and trucks) told me whitworth spanner sizes referenced the diameter of the rod the male thread was cut on. Mr Whitworth was a brilliant guy from the start of the steam age, before his standardising of thread forms every nut and bolt was a one off and many times steel wedges were used instead. However that thread form was well passed its use by date decades before the Tiger Cub. BSF was a more modern thread form and more likely to have been used on a motorcycle (whitworth spanners perfectly fit BSF nuts but the designation is different because a BSF spanner is marked for the distance across the flats of the hex nut it fits).

    • @Dave.Wilson
      @Dave.Wilson 3 ปีที่แล้ว +1

      Mr Whitworth was a brilliant engineer, he developer rifling in gun barrels, the spanner size used to refer to the bolt diameter, 5/16 thread, meant 5/16 AF spanner, until the military decided to change it so that the spanner size was re named 1/4, instead of 5/16. and so on though all the sizes. he also developed threads for lathes that increased the accuracy anther decimal place. But Lucas were just shit at electrical equipment.

    In those you could self teach on a sub 250 cc, or a bigger bike with a sidecar. I think the learning phase could last two years before you had to take a test, then you could go back to learning on a _provisional_ licence.
