[Closed] FAO doubters II (carbon brake mount & potential FLAME-AGEDDON content)

You've got your forks on back-to-front mister!

Yeah, but you're a rubbish engineer, looks like a spoon, I know better, why not v's, let me draw you a diagram.

Did I miss anything?

Is that a disc mount held on by gaffer tape?

Where's the spoon...?

you will die............. 8)

..........horribly

Oh.

So you won't make the stag or the wedding then?

We will send pics to the ward.

Are the braking forces going to want to pull that off (no s****ing at the back) rather than push it into the fork?

Where's the spoon...?

coooeyyyyyyyyyy

good luck : /

You'd better still be alive when I pop up to Edburg in the summer Al

Boy, that's there is the ugliest goddam thing I've seen since yo' mamma's come face.

"More middle class than the rest of stw put together" Bez doing street jive, a true gem!

i don't think i've seen bez post on here for about 5 years and then that gem appears.

brilliant

Oh god not again, can you hang fire for a mo, I'm all out of tea bags and need to plump up the cushions, I have a feeling this could be a long one
Seriously though, i appreciate you may be having fun playing at being an engineer but what is this experimentation costing you not just in money and time but in potentially ruined parts?

Are you really [s]stupid[/s] brave enough to ride that?

Look like electrical tape? Just to confirm, you have the disc on the drive side of the bike, on the front?
Surely the rotational forces will just rip the caliper away from the fork, rather than push it into the leg?
Be careful, the last thing STW needs is a martyr.

What can possibly go right?

Has he got his ambulance ride yet?

It's wrapped all the way around the fork, it might work and it might actually work quite well if you've done it right. The wrap could spread the load to the back of the fork quite effectively and apply it to the fork over quite a large area. Doing it the other way would produce two point loads that could be too much for the fork possibly.

Real suck it and see territory though, good luck!

LOLs.

well done the geniuses who've spotted it's on the RH lag. You lot are truly experts in engineering....[i]with x-ray vision[/i] into computer screens to comment on the structure!

Well done, go you!

Multi-layer full carbon wrap cured under compression. I've not worked out a way of compressing it while preserving a nice finish, I'll just sand & lacquer it if it works out.

Thanks for seeing the idea behind it PR 😀

why has he put it on the front of the right fork leg not hte back of the left as usual? And the rotor is on backwards...intend rotation is marked....see no reason to change that even if the caliper is mounted on the from of the right leg....rotation is chosen so the top of the disc spokes sweep crud down and out, rather than up and collect where spoke hits braking surface.

Noooooo!

I thought it was a proper disc ready carbon fork where the heat from the disc had caused the flamageddon!

Can't wait to see it on next years Darwin awards.

Whoa!

You've attached it with....

[i]tin foil??!!??[/i]
😯

I am loling at the thread in general. I really have no idea whether this will work, so do PLEASE let us know, won't you?
🙂

how did you align the brake tabs?

[url= http://www.cotic.co.uk/geek/#ROADHOG_discmount ]Cy was there a while back..[/url]

I think it will stay on, but my concern is where the load goes into the forks (which weren't designed to dissipate it from where it's now coming from).
Yes, no easy way of a good finish on the outside when you compress the fibre. How was that done? Vacuum? Tape?

And the rotor is on backwards...intend rotation is marked....see no reason to change that even if the caliper is mounted on the from of the right leg....rotation is chosen so the top of the disc spokes sweep crud down and out, rather than up and collect where spoke hits braking surface.

Its a centrelock rotor. If it was the NDS the rotation would be right but when the wheel is flipped to put the rotor on the DS the rotation is then wrong, but can't be changed like a 6 bolt rotor.

I give this a better chance than the rear one. Though the consequences of failure are potentially higher!!! 😯

BB7 with std. washers on the mount.

richmars - PTFE bag and string 😎

Do you lot really think the rotational direction matters?

Have seen your latest work can i just apologise for being a doubter.

45 mins between 'going out for a test ride' and posting again. Did it last longer than the rear, or did you just not use the front brake? Attention-seeking whore aside, I'm enjoying these threads btw.

ah centre lock, didn't know they couldn't be swapped....why do they even bother marking the direction of travel then if they have a poke-yoke?

can't wait to see the result of this one...so long as Al doesn't hurt himself that is.

Do you lot really think the rotational direction matters?

No, just trying to explain it. I'd be more worried about ripping the leg off a fork not designed to take a disc mount 😉

Fair play though interested to see if it works!

The disc rotation direction would be the least of my worries

please tell me more about how you applied the compressionz?

Can you please post a vid again al

Ah yes....GavinB has it. No lawyer tabs on the dropouts and Al doesn't want to shoot his wheel from beneath him, which is very sensible....yet he tris this 🙄

Seems to work fine on a stoppie-tastic test ride, I thought I'd let the thread run a bit before telling y'all.

I could easily not have bothered posting this up, and I knew I'd get the piss taken, but it's a bike forum, and I guess I thought someone might be interested in someone who's actually trying to make bike bits. But hey! I guess no one will be interested in my next project....the ultimate mtb!

Ultimate = Last.

Alas, for you, this might be too true 🙂

disc rotation only matters a tiny ickle bit on very muddy rides. Cack will collect at the top of the spokes on the dis, that's all....slightly affectng braking power.

So did it work?
edit, ah so it did...for now 😉 keep an eye out for cracks at the top of the fork leg, that's where the bnding moment will be greatest, that's where it will fail.

Eh? Quote me in full please - you missed off 'I'm enjoying these threads btw' from the end of that. Precisely because, you know, it's about bikes and modifying them. Glad to hear it's working so far.

For compression (if there's a next time) you can try insulating tape, wound sticky side out (so it sticks to itself). Get it really tight and prick lots of holes in it so the excess glue can seep out.
