This is my first post ,hope someone can help. A friend and I are restoring a 1924 Triumph SD.Can someone tell me what the tapped hole on the underside of the handlebar is for?
-
I would have thought that someone would be able to answer my question ,very disappointing !

I don't feel the urge to apolgise: I have no first hand knowledge of SD Triumphs so I doubt I'm the person to ask. Anyway, since you sound pretty desperate, let me have a go.
Assuming the bars are the originals from your bike, let's assume it is used for something. Does your bike have a stirrup front brake? Maybe something to do with that? If the bike has two inverted levers (front brake on the right, exhaust lifter on the left?), these cables must come out of the inside of the bars somewhere. Is is obvious where this happens? Maybe the exhaust lifter comes out somewhere along the left bar, but the brake cable comes out directly above the stirrup brake, in which case the thread might be for a spring box (for the return) and where the cable joins to the brake rod.
Possible? If not, does it mount one of those single-stem Lucas electric headlights? (Does the bike have electric lights?)
Do you have a parts list? Sales brochures? Magazine reports? Adverts? Photographed every detail of every SD and Ricardo you've come across? Research should really come before nickel plate.
Cheers

Here's a parts list: http://www.triumphmodelh.com/SpareRepairs/SparesManual.html
On page 23 http://www.triumphmodelh.com/SpareRepairs/Pages.php?pg=23 you'll find the brake group. I wonder if you're looking for part no. 2828 and the accompanyiny pieces?

Cardan, thank you for your response and the fact that you are not familier with Triumph SD M/C . However the information that you have supplied is most useful and appreciated . I myself do not know much about Triumphs however my friend Jeff who does not have a computor asked me to assist him . He will come to my home tomorrow and have a look at what info you have supplied .
My bike is a 1927 Raleigh ,model 15.
Regards

I tried to answer this yesterday but the system rejected my password.
Whether it's for a stirrup style front brake would depend upon the year. If you could let me have the frame and engine numbers, with the three letters following the engine number on the crankcase I could give the assembly date and say whether the bike should have a stirrup brake or not. If it should, I can provide a drawing with dimensions for manufacture of same.

Yeah, I advertised for a basket case Vincent Black Shadow for under a hundred quid....guess what, I was disappointed too.... >:(
If you'd Googled for info on Model H's that site would have come up; I know this because I found it when I Googled "vintage Triumph" when after P parts, so rather than bemoan the fact that no-one here knew the answer, maybe you should have chased it up yourself?
You're looking at the best resourcing tool for old bike parts and info ever invented, so why not make use of it? ;)
-
Tri Spec........thank you for your informative reply ,I can get you those numbers tomorrow .
Rex ,you know something, on every forum there is a smart arse! Are you the resident smart arse on this one?
-
Now now Children, play nicely please.
-
Yes I'm quite happy to play nicely as you put it. Perhaps the other plonker should pull his head in and grow up.........there are specific sites for would be ''Jokers''.

What a nice pleasant chap. I ignored your first dig/response, but you seem determined to get some sort of reaction, so here it is.
If you looked properly you would have seen one of these smilies- ;) in my post, and that means it's just banter, nothing serious (as if advising someone to use Google is offensive anyway ::)) but there you go, though judging by the tone of your second post on the SD, I'd say you were up for it anyway.
Well done to you Speedo, chalk yourself up as the first poster I've seen to be unpleasant on this site. :(
You must be so proud......
-
Look Rex ,I asked a simple question ,others responded in an informative manner and I thank them for that . You chose to try and be clever ,your use of ''Smilies '' is your problem ........i responded to what you wrote ,no information ,only an attempt to be clever . If you could or would not give me any information perhaps it might have been a good idea to remain silent .
I personaly could not care less as to your opinion of me and you can sulk as much as you like ,you can also carry on with this but I have said all I want to ......I have other things to do !
-
Thank you for doing us the favour of asking for free information.
Like the man said ,research before nickel plate, you should have built the bike and found/made all the bits first.
If you want people to hold your hand its best not to stamp your foot when you need info.
-
Well said Yebbut, ditto from me too.
Don't ask for help and then throw your teddies out of the pram when people don't drop everything and come running. It won't win you friends on this or any other forum.

how does he get to be an advanced member on his first post? ???

Perhaps back to Triumph stirrup brakes? I hope this thread doesn't end before I learn something more about old bikes.
Looking at the extract from the illustrated parts list posted above (and thanks to John for putting it online - very interesting) it looks like 2828 screws into the underside of the handelbar lug. Is it just a conduit for the outer bowden cable? It seems so, because the usual cable stop and adjuster is a separate part which fits into the tube with the return spring. Why does 2828 exist? Perhaps with a big hole it's easier to feed the cable though the handlebar and get it to come out the big hole; then slide 2828 over the cable outer, and screw it into place to get the outer exiting the bars vertically. Does 2828 have a chamfer on the inside top to allow a "smooth" (but still sharp) bend in the cable (from vertical, to horizontal inside the bar).
Peter C seems to have all the Triumph documents - is this how it works? This was, afterall, the original question.

Thanks Leon for your interest ,Peter C has been in contact with me and his information is valued . Peter seems to think that at a particular date line Triumph changed from stirrup brakes to drum brakes . May be the handle bars that we have ,as Peter suggest could be old stock that Triumph was ''Using Up'
Your theory on part number 2828 sound right . I have put another question to Peter re the valve lifter ,"Where does the cable for this enter the handle bars ''?
I dont think the subject will be taken away ,now there is some sensible content appearing !'
-
The parts list - interesting things, parts lists - tells us the change from stirrup to drum brake was 1924 for the SD. (See details of front wheels/hubs.) If there is no other exit point for the exhaust lift cable, and if it still has an inverted lever (search the parts list for clues!), I suppose the cable comes out through your threaded hole, probably with 2828 to guide it. Can anyone look at an SD to check?

Carden ,we have solved the problem ,a phone call to the owner of the farm where the bike was found on the scrap heap tells us that at one time the bike was involved in a collision . The front forks were wrecked and we assume so were the handle bars . The bars that were with the remains of the bike when it was retrieved from the scrap heap are obviously not the originals ..........thanks for your interest and contribution .
-
Hold on - slow down a bit!
"The bars that were with the remains of the bike when it was retrieved from the scrap heap are obviously not the originals"
They may not be the originals, but given that they were in the same scrap heap perhaps they are. It's interesting to ponder why a set of bars from a completely different bike would be together with the almost-complete remains of another.
I know that SDs used rather "daggy" bars on some bikes, as a few years back we had a very original SD in our club (no longer here) which was fitted with these rather old-fashioned bars. There are various bars listed and illustrated in the parts list (see pages 19, 22, 23, 24), and some are fitted with "Magdyno Lamp Bracket". Are you sure that your bars are not one of the options listed as "Handlebar (Touring Pattern) complete, with "Magdyno" lamp bracket"? Before you throw them away, you might want to think about how you KNOW that they are the wrong bars.
By the way, attached is a photo, from the Yesterdays Archive http://www.yesterdays.nl/triumph-1925-model-p-710.html showing a drum-brake SD. The brake cable exits the handlebar exactly where your "mystery thread" is located, and I fancy I can also see the cable guide 2828 screwed in to said thread... The exhaust lifter cable exits through a hole drilled in the handlebar - perhaps someone brazed this up on your bars prior to plating? (Try not to rely on photos of restored bikes if you can avoid it...)

Cardan.....I can only say '' I dunno'' . You can find many strange things on an Australian farm scrap heap .I hesitate to say that in the same area I found a Triumph frame ,roughly same vintage ,no handlebars . Why I hesitate to tell you is that among other projects I am using this frame and forks to make a replica ''Indian Board Track '' bike . Now purists will shudder but what the hell !
On this same scrap heap was a complete 1900's IHC ''Famous '' engine and nearby a Pasley hot tube engine ....as I said many strange an exotic things can be found
Regards and thanks for your continuing interest .
