new project..

nicklouse

this is going to be an odd ball. and may take some time.

also it is not really an MTB.

initially it was going to be a rat/fixed/pub bike with a front disc.

it still is going to be so but i am going to look at going internal on the hose and strip and paint the frame. Now i know the odd frame painter/artist.....

so build what have i got? well one 16T disc mount cog and a front disc brake.

frame will still be from the scrap pile but the fork needs to be steel to accept the modding that will be needed for the disc mount and internal routing of the hose.

will update as the bits arrive or and selected.

El Capitano

Interesting...

Wouldn't running the brake hose inside the fork weaken it somewhat?

nicklouse

but if you take an over engineered fork to start with? likewise the bars

El Capitano

I take your point and I assume you're not going to be doing anything too extreme on it.

Are you routing the hose through the bars as well?

nicklouse

that is the plan.

well been rummaging in the scrap bikes to see what might be suitable.

surprisingly there was nothing.

but I have managed to kill two birds with one stone.

I will be using the frame and possibly the forks (if i can work out the brake routing) the wheels and cranks will be going onto a 20 year old bike that needs gears and a brake.

oh and the frame will be this one.

nicklouse

oh any thoughts on colour?

need to do some serious modding to the fork as i need it to be aheadset compatible not threaded.

old skool XT lever


newer caliper



and old skool metal finish (great for the paint finish) hose.

when you say artist, what kind of thing do you want to do on the bike? I originally wanted a bike with large tubes so I could set my artist girlfriend to work on creating me something unique - then i ended up with the Ellsworth with comparatively narrow tubes to the 08 Enduro I was thinking about.

We're looking at using Jon Burgerman as our inspiration;


He creates lots of doodle monsters which I quite like 8)

Two thoughts:

Stealthy matt black. The same for as many components as possible.

Or, bright Bright green - and get the twinrails in the same colour.

El Capitano "Stealthy matt black" + carrot

but lets see.

Won't you get internal cable rub with that?

where? how? nope.

nicklouse

right work has started on the fork.

need to change it from a 1 1/8th threaded fork to a 1 1/8th Aheadset fork.
Also needs lo lose the V brake mounts.



no the mounting of the caliper woll be fun.

thought i had an adaptor made up but the angles were way off.

but will be something like this when done.



just a bit of welding to do tomorrow.


and i need to make a 130mm X 20mm axle.

El Capitano

So you're mounting the caliper on the right-hand leg?

cat_with_no_tail

I must admit, this is all a little beyond my feeble mechanical comprehension. I'm know that Nick knows more about this sort of thing than anyone I've ever come across though, so I'm sure it'll be very interesting to watch.

nicklouse

yep the caliper is going on the right leg , front.

steerer extended. plug welded and seam welded.


has been ground down since.


the seat post and saddle are just to get a feel.




Bars maybe... wheels just for looks as they are in the shop for repair and have a broken spoke.

"grips" just as bump stops.

nicklouse

so this afternoon it was disc brake mount time.

first make a reinforcing plate and attach.



then make and fit the caliper mounts.



then put together till tomorrow.

Anonymous

I'm curious.
Are you mounting the callipper on the front to prevent any chance of the QR opening itself?

nicklouse

nope. just cause I can.

it also will make the fender fit better.

and it is where they should have been from the start.

Anonymous

fairynuff.

nicklouse

Right today has been finishing off a few bits.

like the brake hose routing.



how to cover the hole?





and



graphics are history as is the load carrier and the front fender is back on.

next job strip back down and paint.

and build some wheels.

Spugnut

Looking good Nick. I'm intrigued to see how this turns out.

nicklouse

new rims ordered. black. 32 spoke and disc only.
tyres ordered black and bald.

need to steal a dremel of a mate.

found some powder coaters.....

allthegearnoidea

Love it! especially the internal cable for the front brake,
love the reasoning behind it too, 'Because i can' spot on!!!

Dick Scruttock

Plug weld/braze the hole?

nicklouse

Rick the issue is the hose can not be removed for the welding. i had to make the hole in order to fit the hose. why well they are old stock shimano metal braided hoses with NO plastic coating. So there was noway they would be sold.

so water/oil and even liquid nitrogen have been thought of.

Anonymous

here's two ideas, Nick.
Attatch a piece of string to the brake cable, and pull it through, leaving only the string/wire/whatever you've used running from the lever to the calliper.
Then weld the hole up.
Now, use the string or whatever to pull the hose back through the fork, and re-attatch.

OR.
See if you can find a rubber grommet that would fit it. I'm thinking of the kind that you'd use to blank off holes in electrical boxes. If you have a nearby electrician's suppliers, they should have something to fit.

nicklouse

the string wont work as the hose has pre crimped banjos which is why i need the hole in the first place....

Gromets been thought of and is on the back burner..

Anonymous

hmm. how did you get the hose through? I think I must be missing something, but I can't figure out why you couldn't pull it through.
