Great thing about old cars and bikes is you can tackle bits like switches apart and restore them. Very satisfying but boy is it fiddley Nice job Mr T..
Thanks Russell
Many decades ago a friend of mine came across a pair of Japanese Quails in a pet shop. Easy, just treat them like chickens. His chickens, predictably, were free range... Opened the door the next morning and vroom... Bye bye, quails... Anyway. Switches. Back in the '50s teams of young womenfolk would assemble hundreds of these switches a day, all the time moaning about what a knobend Albert had been coming home drenched in a barmaid's scent. Her hamster died, I gave her a hug... Lesson to be learned! Don't replace something that you might be able to fix... 👍
Sage advice Bill, oddly enough we started keeping quails about 5 years ago when i happened to go round to the bins by the front door to find a quail hiding behind them.....no idea where he came from as we live on a main road! He went on to sire a batch of offspring even though he was totally useless at " IT " if you know what i mean 😉
You are a very patient man Mr Tweed, there would have been a lot of foul language coming from me during the switch rebuild.
oh there was a bit Glen.......the magic of editing
I’m preparing to rewire my D14. This is great for reference. Thank you. Looking forward to the next episode.
Glad to be useful 🙂
Fiddly job at best. Only done one completely from scratch, loom replace and upgrade and that was on the Riley RM. It amazed me how much better starting, lights and charge was. Actually cleaning my front cut diesel mower loom as part of a salvage project, when you posted. Must be telepathy!! Thank you for posting.
Ah the world works in mysterious ways Mr B 😁
Fantastic, those intros just get better and better 😂
Glad you enjoy them 👍

Very inventive. I did like the one with Mrs. Tweeds stocking feet.
I was engrossed with your patience restoring the switch. You already knew what components would be found and taught anyone attempting this to learn first of all how it works before dismantling! My son restored two motor bikes, one was a Triumph sports Tiger cub and the other was a 1955 Ariel Red Hunter. He dicovered the gear box was a seperate unit made in the 1930s. Some British manufactures after world war 2 could never afford further investment in new tooling for years and cobbled bikes together from manufactured parts and still using pre-war machinery which the photos you showed from BSAs manual of different models testified to.
Glad you liked the switch restoration and even before the war they seemed to grab bargains if they could , the Excelsior has a mix of imperial and metric bearings in the engine/gearbox along with the Bantam which also metric wheel bearings!!! ( more understandable on the Bantam as the first ones where a copy of the German DKW 125 ) ...... these old vehicles keep you on your toes ( the 1927 Chevrolet had metric bearings in the rear axle ! ) .
@@TweedsGarage Interesting about the Chevy metric bearings, I would never have expected that until at least the 70s or 80s here in the states.
I love a strip down of parts that were meant to be disposable. That's the appeal to older things, you can get inside them and fix them . Too many things are sealed for (short?) life and you can end up destroying them trying to get inside.
I've always loved fixing things and as a nipper I remember bending back the tabs of a tinplate clockwork car to gain access to re-attach the spring. I guess it all started from there. Even today before I throw away something broken I still see if I can fix it.
I'm afraid you've been done, Mr Crispin's toothbrush has a royal crest on it. Hope you didn't pay a lot for it.
Thanks for the video, I loved the suspense of someone else getting those three springs in place.
Damn that eBay it was listed as a genuine item with certificate of authentication signed by the man himself !!!! Glad you enjoyed the tension 🙂
@@TweedsGarage When dealing with small springs in tight places, there is always drama and tension to be had.
You are a brave man, taking that switch apart. Well done on not breaking off the tabs. Or anything else for that matter. Fragile is the key word. That is a lovely shade of green in there.
Verdigris city....people pay good money for that effect!
@@TweedsGarage
Indeed they do.
Lovely work! That switch was horror and it came up so well.
Cheers, Peter.
it was awful.......I´m still in therapy
@@TweedsGarage Get well soon!
My brother bought a B175 Bantam a few years ago. The front mudguard is secured by stays, at the front & back. There is no fittings where the mudguard passes between the forks, so the mudguard "floats". There are threaded bosses on the inside fork legs, full of factory paint. There are NO holes drilled in the mudguard anywhere in this area.I can only presume that it left the factory like this. I will make something up, if I can get a glimpse of the said part in RUclips videos...Your videos are hilarious & helpful. Many thanks.
Just had a look in the parts manual ( and had a read of the repair manual) the mudguard is secured by the front and back stays but it also had a central support mounted on the inside of the guard that secured with bolts into those holes on the inside of the fork legs, hope this helps Martin.
Thank you for the advice, sir. i just fabricated my own version. Seems strange that it left the factory without it.@@TweedsGarage
Thankyou for a very informative video, i will try some of the items, instead of purchasing new if available
Glad you found it useful
I always thought what we need for fiddly jobs with springs and ball bearings is one of those baby incubator things to do the dismantling in. I suppose you'd have to take the baby out first... And for continuity testing hell, try building Enigma machine rotors!
I can only imagine Simon, I used to have to continuity check wire wrapped chassis units for multiple circuit boards......tedious to the extreme.
@@TweedsGarage
We had a job with a motherboard for a box on the B2 bomber that needed to be tested 100 percent for any problems. I set up an automated testing machine from the Drive In Movie Testing Company (Ditmtco) that ran all the connections. The box only tested 256 connections at a time so the process required 16 steps, moving interface cards inside the unit to get it all done.
.
I understand your pain in checking out wire wrap backplanes. Like Ykes!
Great episode Mr Tweed, excellent workmanship. Can’t wait for the next instalment 😀
Thanks for tuning in.
Marvellous progress Mr Tweed.
I've been purchasing parts like Imelda Marcos bought shoes....
Great episode Allan, I was expecting a jack-in-the-box experience whilst you dismantled the switch, I've had similar experiences and some of them best forgotten. I also remember Pifco torches and yes, what a marvellous bit of kit, you just can't beat tacky plastic and pressed shiny metal :-)
unfortunately Jason I said Pifco too many times and ended up buying a Pifco motorists torch off of eBay..........currently poised by the front door excitedly awaiting its arrival !!
That was a really successful job ! Really nice to be able to get a new wiring loom together with new connectors, I wonder why they have changed the colour coding on this, I would think the number of these looms that they sell would not make it viable to start producing a new run, so they could be old stock re packaged, you ae lucky it was not fitted with Bosch equipment , that would have self destructed many years ago, when you consider this has been used and abused for 50 years and it still cleans up like new then look at the equipment we buy today this must have been at the very end of a repairable era, I think the crud inside the switch must be the original grease used on assembly of the switch. But it has all come out like new! Well done Allan! Chris B.
Thanks Chris, they did come out surprisingly well considering Wipac was the bargain basement when it came to electrical equipmentn and yes in the UK there is the assumption that Bosch equipment was better but I can affirm on MK1 Golfs that the fuseboxes were absolutely dreadful .
@@TweedsGarage I think the "Bosch is best " thing is brought about by their aggressive marketing ploy, unfortunately the sheep believe it, but from experience everything electrical that fails on my Range Rover and Defender has "made in Germany" stamped on it, I think the problem is that people think a 50 year old electrical device should still perform as new, but electrical things do not like vibration and filth thrown at them. You Bantam has really good front forks? I remember when they had squashed conduit with a rubber bung for springing! Chris B.
Great stuff Alan, you epitomise the old saying that the art of fixing things is having the bottle to take them to bits; which you did with the switches, cracking job mate... Sadly I'm going to be picky, "Loom" seems to be a term which has floated across the Atlantic over the years, back in the day I would call it a wiring harness, the brief glimpse of the manual showed the word "harness" which backs me up somewhat, It's a bit like calling a pillar drill a drill press; I mean what's all that about...Anyway enough of that, looking forward to the next installment mate, I hope it all works... Allen O'Rourke...
You are quite correct, as an Englishman I hang my head in shame Alan, but to be fair when I done my apprenticeship we were taught the art of looming and lacing for aircraft wiring looms/harnesses, it was interchangeable, I think the whole aircraft wiring was a loom and harnesses were sub assembly wiring ( nothing looks finer than a tidy beeswax cord laced loom )
@@TweedsGarage
A well laced harness is a thing of beauty, best done on a loom.
I myself have always called assemblies of individual wires with perhaps some cables thrown in for good measure harnesses. When doing the drawings, I have always used the term Loom for the board or other fixture used to make the harness. But this is just me, everyone is different.
Any time that fitting something to a classic bike upsets the concourse nit pickers makes it worth doing. 🙂
you're not wrong there Stuart.
So true, fun to tweak them by installing LED lights in classic cars. For real evil, the spinner wheels on an old Rolls is always good for a giggle.
Wipac Tri-con switch, I think the red button is for a magneto cut out, not used on a Bantam. A Bantam would use a Du-con switch which does not have the red button.
Nice bit of Wipac info, cheers 👍
There's nothing as exciting as a new Lucas box of darkness. I was on the edge of my seat while you disassembled that switch. I thought we were in trouble couple of times! As always entertaining and educational. Cheers from the shed
With your condition I know we can't have anything to exciting so brace yourself for more switch servicing and tyre changing......and sit back on your seat as it's bad for your posture ;-)
😁@@TweedsGarage
@@TweedsGarage
Would it also be possible to let Shedby watch some competitive paint drying?
@oldfarthacks I've got some chassis painting to do so probably 😉
a lot to be said in favor of carbide lights.
Carbide lights can be such a blast.
Literally. An old geezer told us that he went into a shop leaving his lit carbide lamp unattended. Some kids started messing with the lamp settings. There was an explosion. He ran out, the kids were gone, and one handlebar was bent back!@@oldfarthacks
I like your humour and other content but I want to ask you if you think as I do to it's a good idea to run earth wires to everything rather than using the frame as ground ,I have done it on my c15 the nips did it donkeys years ago it seems so obvious to me that it should make the electrics work better maybe?cheers all the best and please keep up the good work
Yes indeed Frank, especially with a 6 volt system, it needs all the help it can get, it may have been sufficient when the bikes were new but after 50 plus years of corroded fixings and mating surfaces its a miracle if the electrical system works at all and its not a difficult task to run a few earth wires .
