I bought this headset at great cost but when i just tried to fit the top stationary cup it seems too big it will only go in lop sided. I have not tried the bottom as i dont want to damage the finish. Im not sure if these are hard to fit maybe i need to try harder. The sizes on the box says cup o.d 32.7 & crown cone i.d.26.4 can anyone shed any light please.
-
Is the frame powdered? If so, then dremel the inside of the tube. Also put the cups in the freezer for an hour, then try inserting them, works every time for me :daumenhoch:
-
The frame is original chrome but i dont want to bash the cups in if there the wrong size can anyone confirm that this SHOULD fit then i can get to work freezing them & bashing them in :-\
-
Have you measured it against a normal cup? If these is a significant difference then dont try, but I know that the cups and frame tubes are not constant and hammer fit does seem to be used a lot of the time. use a tiny bit of grease in the frame when you fit it :daumenhoch:
-
I did compere them to the ones i took out & there was maybe a minimal size difference hard to tell because of the shamfer on the tange cup but it certantly wasnt a significant difference
-
Then I would try the freezer, when I have done it in the past, they slide in sweetly with minimal hammering......
If you can borrow a vernier gauge then you can accurately check the diameters first if you need re assurance :daumenhoch:

Nice one ratty im off to the freezer :daumenhoch:

Let us know how it goes :daumenhoch:

It's a T/A, these things are forgiven. :smitten: :smitten: :smitten:
What's with the Limited Edition thing going on there though?

Ive notice a few bikes appearing with non stock decals & designs & wanted to build a skyway using just black & silver/chrome parts. but then the blue & red decals ruined the color scheme so i got Del off here to do me some custom decals & the result is what you see. I like it do you ? im bringing it to MK just to have a ride around im not gonna race it or show it as its not finished. Firebird also said he can make me a matching padset but time & money are not on my side at the mo bit gutted but hey i will finish it maybe not in time for mk but i will :daumenhoch:

Another pic
-
Yeah, I do like that, mate. :daumenhoch:
Hmmn, seeing as Del can make non-standard decals and Firebird can make non-standard padsets, I have an idea for a T?A build forming...

Some people wont like it cus they think old school should be built as era correct but i like these custom designs like the yellow skyway that was for sale on here recently.

yeah true.
The way I look at it though is that i'm building the bikes for me, if no-one else likes it, then fook em. :LolLolLolLol:

that skyway looks great ben!
and top tip from the ratty
-
Could you take some more pictures of the decals for me please? Perhaps wider angle but not too far away?
I'm intrigued.
Thanks

Where's your chrome shim on the headset. You haven't put that on and it needs to be there. :daumenhoch:

here is the head tube & down tube decals before i fitted them
-
for some reason there is not enough thread on the forks but as im going to get the right skyway forks im hoping that they may be a bit longer does anyone else know why the fork thread is not long enough ?

Yep, I like those decals a lot. I think i'm going to see if I can get Del to do me a set of black/white decals and Firebird a set of black pads with white/grey writing, if they are amenable.
Good job mate.
-
I've just realised that the down tube sticker you have there is a single. Do you not have wraparound ones?

Looking good m8 :daumenhoch:

I had the same problem on my TA but i had one that was not so thick and used that.
I also had a nightmare getting the headset in. In the end i just went for it and it straightend out on the last couple of turns, complete nightmare though.
-
nice skyway mate !!
i remember having a nightmare getting headset cups into my Hitch, i took it to a bike shop in the end, they took ages to get them in properly,...aparently the headtube was oval ? so some edjat must have dropped It at some stage, it all went in in the end, and works perfecto !
-
Mine took some beating to get it in i just didnt try hard enough before in fear of stretching the headtube. as soon as i found out it should fit & the Ratty freezer trick come to light ( i would add that you should pick the parts up out the freezer with a tea towl tho horrible feeling when they stick fast to your hand like super glue :2funny: I just got a peice of skirting board & a hammer & went for it trying to knock the high end down & it sorted its self out with no damage to anything chuffed :daumenhoch:
