Tickle T-5 .

A ancient 70s Motorcyle Maniacs mag stated the rake was 27.5 for manx , 26 for wideline & 24 for slimline . from memory . Though in that order if not exact .

Obviously the jig for each varied . Saw the other day something saying Manxes were heavier tube than Inters . 16G Vs 18G , saying the Inter frame was lighter .
 
None of that sounds right at all Matt.
Throw all the bits of paper up in the air again, and see how they land this time...

Being niether an inebrite or an Australian , I wouldnt know . Sounds like youd better have another beer .
You sound like a school teacher . Someone who couldnt get a real job if they tried ?

' WE ' have found by concensus that you can debate minuate for ever . STICKING a tape measure on them might help .
BUT , a generally knowledeable and accurate maGAZINE CONSIDERS EACH TYPE TO VARY , aS STATED .

Just in case anyone IS intrested in reality rather than concensus . Otherwise we'll all end up with Camels instead of Race Horses .
or is that penny farthigs instead of decimal currancy .

Or WAS it the WIDELINE at 24 & the Slimline raked out more - with the MANX 27 . :lol:
the N.O.C. seems to consider both road chassis to be Twenty Four Degrees .
 
Now I would be very pleased to see the complete set of those drawings !!!

I own what I think is a replica slimline frame. - It has a 1956 number stamped on a slimline frame which is a bit out of sequence :-) One day I should sit down and measure it all up.

But the main reason I want to check the frame is that it handles extremely well and the rider rates it over any other featherbed he has ridden. But I would very much like to know what the original numbers were.

Thanks Matt, and I've grabbed a copy of the your photo of the pristine manx.
My friend has a very fast Triton with a manx frame. I asked him the question and he said without hesitation that the rake is 24.5 degrees. I've never known him to be wrong about anything in relation to his bike. I know what 27 and 26 degrees look like on the Seeley and the TZ Yam. respectively, the manx is much steeper. I'd take notice of the NOC long before I'd listen to Rohan.
Have a look at the angle on the forks on my bike to the right of this post and compare it with the forks on the manx in Matt's photo. - The Seeley looks like a bloody chopper.

The easiest way to check the frame is by using a magnetic base protractor. If you are racing you should buy one - very useful for checking out the bikes of the fast guys as long as you are not too obvious when you do it. Replica manx frames made in Australia for racing usually have 26 degree rake, and handle like Suzuki two strokes - no long sweeping access to corners, you just front up and tip in. I was once involved with building a triton with one - it ended up winning many historic championships. The guy who owned it also has a Drixton Aermacchi 350, it has extremely steep rake, and absurd offset fork yokes. I commented to him about the huge offset, and he said it is the secret to it's good handling.

'Pristine' model of what Manx though. ?
That doesn't even look like any recognisable year of manx.
A real hotch-potch of bits, in fact.
Still a nice bike I'm sure though...

Saw who and where saying what = details ??

531 tubing was THINWALL HI-TENSILE TUBING.
The 500's (Manxes) got heavier gauge than the 350s.
I have a bicycle made out of something very similar, and its chief claim to fame is that it is LIGHTWEIGHT.

It would be odd indeed if the Inter was lighter, not being made out of such tubing.
The Inters are not noted for being especially lightweight either.
Even the mudguards were steel, in quite a heavy grade....
 
It's always been my understanding that there is little or no difference between the stiffness of 531/ T45 tubing and similar sizes of "ordinary" cold drawn steel tubing, until they were welded, when the standard steel tubing would loose some of it's properties and the 531/T45 type of tubing would not. This would make the frame made of 531 or T45 either stronger for the same weight (if identical dimension tubing was used), or lighter for similar strength. For production the standard steel tubing was significantly cheaper than the 531/T45 variety, hence its use.
Any comments from the experts?
cheers
wakeup
 
I don't know about 531 tube, however a friend has made frames form locally available chrome-moly tube, and it is quite difficult to bend - the spring-back is significantly different. The last one he made was for an SF750 Laverda - was quite successful, however not so easy.
 
Elementary my dear Watson.
The tensile strength/yield points of mild steel is quite low, so it is relatively easy to bend to a new shape.
Hi tensile steels like 531 and chrome-moly are made of stronger stuff, so they need (a lot) more muscle to force into a new shape.
Reshaping steel goes beyond the point where springiness comes into it...
 
Dear Mark!
Do you think, it´s possible to get the other half of the sketch?
I´m not a member of the Norton Owners club, so I cannot write to Phil Hannam personally

Do you (or anyone else) have the rest of this drawing?
I wanna make a CAD-sketch of it.
greetings from austria

and not the cangaroos
sincerely

The sketch is all there but screen resolution will show it cropped.
Right click save on it or right click view image to see all of it.

The frame drawing is only half there - unless someone in the NOC can get in touch with Mr Hannam.

Dear Rohan!
I tried last week, but I fear because of his hw-crash, he´s unable to repost, therefore my question to this community
 
got the complete file last week from a swiss guy.
I just began to transform into CAD and i will put on file to th eboard
